      Abstract. Reflective learning is an important activity of knowledge-
      workers in order to improve future working-behaviours. The insights
      gained by reflective learning are based on re-experiencing and re-evaluating
      past working situations. One time- and cost-effective way to support re-
      flective learning is the employment of applications that collect data about
      working processes, store the data in user profiles, and visualise it in order
      to provide timely feedback to the employees. However, a single applica-
      tion can only capture part of the data that might be relevant for reflec-
      tion and the parallel use of several applications leads to high demands
      on the user regarding the interpretation of relationships between sev-
      eral single visualizations. A combined visualisation of data captured by
      different apps should enhance the support for reflection about the work-
      ing behaviour and experiences. This paper introduces an overlapping
      user profile application, which combines and aggregates data captured
      by various applications. The goal of this overlapping application is to
      provide higher-level reflection possibilities by combining visualisations of
      different application data in order to better induce and support reflective
      learning at work. A first proof-of-concept of such an approach indicates
      that a combined user profile application and especially it’s visualisations
      can be beneficial with regard to reflective learning and can enhance the
      awareness about the multiple aspects of a user’s work life.

1    Introduction
Today’s work environments are constantly becoming more complex, globally
integrated, and knowledge-centric. This simultaneously leads to a stronger need
of employees who are motivated and capable to reflect upon their activities and
as a consequence adjust their working practices to new demands. Especially for
knowledge-workers, reflective learning is an important activity to re-experience
past situations during work and to learn from them in order to improve their
future working-behaviour [2]. One possibility to motivate knowledge workers
to become reflective practitioners is to support them with corresponding tools

  or applications, which could be easily integrated into their daily work-life [14].
  These applications have the task to gather data from work processes and to
  provide guidance for reflection in form of raising awareness and offering triggers
  with regard to unusual or extraordinary work related experiences or situations.
  In contrast to formal learning settings, reflective learning at the workplace deals
  with informal and self-regulated learning, where challenges like no additional
  working effort, easy integration in daily working routines as well as a clear benefit
  for knowledge workers have to be considered right from the beginning.
      In order to support reflective learning at work, within the EU-funded project
  MIRROR (http://www.mirror-project.eu) several applications have been devel-
  oped, which aim at motivating and activating users to reflect upon their indi-
  vidual working experiences. After the reflection process itself, knowledge work-
  ers should have gained some benefits or insights for themselves and as con-
  sequence derive and apply behavioural changes for future working situations.
  These changes should permanently improve and facilitate the handling of up-
  coming similar situations or experiences.
      The applications developed within the MIRROR project have been applied
  within a wide range of working environments (e.g. care homes, hospitals, IT com-
  panies, and emergency situations) and support various sets of professionals (e.g.
  knowledge-workers, nurses, physicians and carers as well as emergency workers).
  Each of the developed applications collects and gathers different kinds of data
  and stores them in their corresponding user profiles. This data encompasses on
  the one hand information about the user. On the other hand it consists of in-
  formation on users’ work processes, which is captured automatically or inserted
  manually during the user’s work. Examples are application switches, application
  usage and documents used while working on a PC as well as manually inserted
  data such as the current mood status of the user, individual notes, feedback
  on different working situations, ratings, scores of serious games or quiz results.
  The collected data is stored within the applications themselves and for some
  applications additionally in the so-called MIRROR Spaces Framework [20], an
  underlying data storage system for exchanging data between applications. In the
  spaces framework, the user’s data is stored in the user profile and is accessible
  only by its owner. Each of these single applications visualises the data for the
  user in a sophisticated way with the goal to trigger reflective learning. However,
  user studies conducted in different environmental settings (e.g. [9], [16]) showed
  that single applications can only capture part of the data that might be relevant
  for reflective learning. Participants of these studies asked on the one hand for a
  better guidance to interpret the data in order to initiate reflection. On the other
  hand they wanted to see a clearer benefit for themselves, which would serve as
  motivational trigger to use the application and to reflect about the captured
  data. Thus, similar to research outcomes from the field of learning analytics, we
  found that a combination of data is often more adequate for successfully support-
  ing users. Whereas learning analytics addresses self-reflective learning mostly as
  important aspect of self-regulated learning in formal learning environments, we
  focus on work-related reflective learning in informal learning environments.

      With this paper we want to present a first approach on how to meaningfully
  combine and visualize data captured by different applications. The goal is to
  provide a greater variety of reflective learning opportunities in order to facilitate
  deeper insights on one’s working experiences. We are aware that this approach
  raises privacy and security issues which need to be carefully considered when
  employing the app in a real working environment. However, for this first approach
  privacy and security were only of secondary interest, but will of course be treated
  in upcoming research settings.
      Therefore, we developed the so-called ”MIRROR Integrated User Profile”
  application (MUP App) which has the task to integrate, summarise, analyse,
  and visualise data captured by several different applications in order to induce
  and support reflective learning at work. For a first proof-of-concept, we used
  two different applications in parallel, namely KnowSelf and the MoodMap App.
  KnowSelf automatically captures work activities on a PC, whereas the MoodMap
  App allows knowledge workers to easily state their moods during a working day.
  We collected, aggregated, and visualised data from a small sample of knowledge
  workers to to get a first impression of users’ interest and motivation and the
  app’s usefulness. From this we derived the following three research questions:
    – RQ1: Are participants interested and willing to use more than one applica-
      tion in parallel with regard to reflective learning?
    – RQ2: Does the MUP App as overlapping application facilitate reflection
      about users’ working experiences and contribute to raising awareness of mul-
      tiple aspects of their work life?
    – RQ3: Do participants perceive any individual insights or benefits for them-
      selves?

  2.1    User Profiles
  Since the terms user profile and user model are not always used in exactly the
  same way, it is essential to clarify our understanding and usage of the term user
  profile, which we base on existing theories regarding user models and on our un-
  derstanding in MIRROR described by [15]. User models in general are models
  that computer systems have about their users. The data in such user models is
  automatically captured by the system and is mainly used in information retrieval
  and intelligent tutoring systems or user-adaptive learning systems (see e.g., [10,
  1]). User models, which are utilised in learning environment systems for mod-
  eling the learner and the corresponding learning activities, are called learner
  models. These types of user models are created by the systems automatically
  and are not directly accessible by the users via user interfaces. Furthermore
  they are used to adapt teaching strategies or to inform the learner about the
  learning progress as basis for reflective learning. Additionally [3] suggested that
  learner models should keep data like knowledge, interests, goals, background,
  and individual traits, thus abstract concepts relevant for learning. In order to


                                           53
Application overlapping user profiles to foster reflective learning at work - ARTEL14


  apply a user model or learner model as basis for reflection on one’s own learning
  activities, achievements, or progress towards the individual learning goals, it is
  necessary to make the models accessible and manageable for the user, which was
  explicitly suggested by [12] and mentioned in [4, 5, 13].
      In MIRROR we prefer the term user profile (UP). Although the MIRROR
  user profile (MUP) is based on theory and research of user models, the term user
  profile better reflects its mission in MIRROR. First, the purpose of the MUP is
  to guide and support reflection by mirroring user data in the form of activities,
  experiences or artefacts of work, notes and insights, moods, work practices, and
  other concrete data sources back to the user. Secondly, we intended these user
  profiles to be created and maintained by a mixture of automated methods and
  manual management, where the process of editing or updating the data may also
  explicitly trigger reflection.



  2.2    Learning Analytics


  Although learning analytics is not in focus of our work, several approaches,
  methodologies and technologies of this research area are closely linked to reflec-
  tive learning. Learning analytics deals with methods for analysing and detecting
  patterns within data collected from educational settings or learning environ-
  ments about the learner, and leverage those methods to support adaptation,
  personalisation, recommendation, and also reflection. Siemens [21] defined learn-
  ing analytics as ‘the use of intelligent data, learner-produced data, and analysis
  models to discover information and social connections, and to predict and advise
  on learning’. The focus of learning analytics is on the support of the learner in
  formal learning setting, while in our work the focus is to support the knowl-
  edge worker in an informal learning setting. Nevertheless, the parallel to our
  work is evident. Also approaches like learning dashboards for example described
  in [8, 19] present an overview of the learner’s own learning activities and learning
  progress, and in relation to colleagues at one glance. Such combined visualisa-
  tions support self-monitoring for learners and awareness for teachers as well as
  empowers the learners to reflect on their own activity, and that of their peers.
  Explicit traces (e.g. the learner’s entries in a chat or a discussion forum) and im-
  plicit traces (e.g. the learner entering a course or clicking on a document) stored
  in the corresponding learner profiles serve here as basis for the aggregation and
  visualisation of the gathered data.
      The main focus of learning analytics is to support the learner while learning
  in an educational setting or learning environment. Although learning analytics
  includes also reflective learning approaches (e.g. [18, 17]), our work can be clearly
  distinguished from these approaches by focusing on knowledge workers in real
  working environments and and to support reflection on working experiences or
  working artifacts in order to learn from them to improve future work.

  2.3    Reflective Learning
  Individual reflection takes normally place in every day’s life and obviously also
  during work or work- related situations. Reflection may be triggered by different
  reasons for example by conflicts or problems, by unexpected experiences or by
  a person acting in a complete different way in comparison with the individual
  (external trigger). But also if an individual feels uncomfortable, for something
  bothers her or an inner voice is nagging, without being able to make this feeling
  external (internal trigger). As reaction, a reflection process may be triggered with
  or without the awareness of the person. This reflection should lead to an individ-
  ual insight or outcome which may be used to guide or adapt future behaviour.
  Within MIRROR we follow the definition of [2], who define reflective learning as
  ‘those intellectual and affective activities in which individuals engage to explore
  their experiences in order to lead to new understandings and appreciations’.
      Bringing this together, reflection is both a crucial part of learning and a re-
  sponse to past work experiences. These experiences as well as the behaviours of
  the individual engaged serve as starting point for the reflective process. The de-
  sired outcomes of reflection may lead to personal synthesis, integration of knowl-
  edge (internalisation), validation of personal knowledge, a new affective state or
  the decision to take on actions for future events. To achieve these results the
  characteristics of the individual (learner) have to be taken into account as well
  as the intention of the individual self. Individual reflection may occur sponta-
  neous and unconsciously and in any possible situation especially then when it is
  not expected [6]. Of course it can also be consciously triggered by peers super-
  visors or by meeting created specifically for that purpose [7]. Within MIRROR
  we focus to initiate reflective practices with the support of technologies, which
  might automatically detect unusual working patterns and working behaviours
  and by making the worker aware of them in form of reflection triggers or explicit
  reflection guidance e.g. by means of prompts.


  3     Examples of MIRROR Applications
  In the scope of the MIRROR project a series of applications supporting indi-
  vidual reflection have been developed and evaluated in different settings [16, 9].
  Some of the user studies showed that gathering and visualising data captured
  by single applications is not always enough to initiate reflective learning. To il-
  lustrate how the MIRROR applications support reflective learning, we want to
  shortly introduce two applications, namely KnowSelf and the MoodMap App.
  The same two applications will later be used as example for a possible combined
  usage and integration via the MUP App.
      KnowSelf automatically captures work activities (used applications and
  resources together with the exact time of use) on a PC, provides simplistic project
  and task recording and presents an overview as well as different visualisations
  of the captured data [16]. Providing these visualisations regarding time use at
  work should lead to reflection on personal time management and potentially
  motivate to consider improvements in this respect. The user profile of KnowSelf


                                           55
Application overlapping user profiles to foster reflective learning at work - ARTEL14




                    Fig. 1. KnowSelf (left) and MoodMap App (right)



  is not a conventional user profile, because it consists only of user activities, but
  not of information about the users themselves. The application stores all work
  activities captured on the user’s computer, including window focus and title, if
  applicable the system location (path) of the resource, focus switches, and idle
  time. Additionally the user can manually record time spent on projects or tasks
  and save observations. The collected information is displayed on a timeline and
  as statistics in the form of pie charts.
      The MoodMap App is a web-based application, which allows knowledge
  workers to track their mood during a working day or virtual meeting and recapit-
  ulate their work experiences afterwards. The MoodMap App provides an easy-
  to-understand user interface to state individual mood points by simply clicking
  on a bi-dimensional coloured map. Each mood is composed of two dimensions,
  namely valence (negative to positive feelings) and arousal (low to high energy)
  based on the model proposed by [11]. Additionally, it provides several visualisa-
  tions on an individual as well as collaborative level, to make users reflect on the
  mood development over time or to provide easy comparison possibilities of one’s
  own mood with the mood of others for example colleagues or team members
  of the same team. The application related user profile stores information about
  the user, sharing settings for security and privacy issues as well as individual
  email settings. Furthermore, individual moods and inherent notes, correspond-
  ing meetings, context information of a day or meeting, as well as personal diary
  entries are stored in the internal user profile of the application.


  4    The MIRROR Integrated User Profile (MUP)
  Insights from evaluations conducted separately for KnowSelf and the MoodMap
  App led to the conclusion that single applications capture only part of the data
  that might be relevant for reflection [9, 16]. Although the developed applications
  proved to have high potential to trigger reflection at work, we wanted to go
  one step further. As a first step, we made triggers from different sources easily


                                           56
Application overlapping user profiles to foster reflective learning at work - ARTEL14


  accessible to the users, in order to further facilitate the reflective learning experi-
  ence and help users to get more insights at one glance. Thereupon we developed
  the MIRROR User Profile (MUP) concept, which focuses on the combination
  of the captured data and corresponding sophisticated visualisations. An early
  prototype of the MIRROR User Profile Application (MUP App) was realised
  and tested with a small sample of knowledge workers.


  4.1    Prerequisites for the MIRROR User Profile

  In order to efficiently implement a common MIRROR user profile, it is of crucial
  relevance to use data captured and gathered by several MIRROR applications
  and not only by a single one. To achieve this, we employed the MIRROR Spaces
  Framework, an underlying data storage system developed within the MIRROR
  project to store and exchange data of the applications. For the development of
  a common user profile based on the MIRROR spaces the following prerequi-
  sites have to be considered: assumptions regarding (i) data, (ii) reusability, (iii)
  sharing, (iv) privacy and security, and (v) accessibility by the user interfaces.
      Data stored in the MUP can be divided into three different types, namely
  personal data about the user, private data, and shared data. Personal data about
  the user consists of general information about the user (e.g. name or email ad-
  dress) and login information. For the data implicitly captured by the MIRROR
  applications (e.g. work history in KnowSelf) as well as data explicitly inserted
  by the user (e.g. mood in the MoodMap) it is essential that the user has full
  control over her data by deciding for each type of captured data, whether it is
  private or can be shared.
      Reusability is one of the major potential benefits of the MUP. By storing
  the data according to a predefined data format, applications are able to reuse
  not only their data but the data captured by other applications and other users
  as well. Account information can be stored once in the user profile and then be
  used by all MIRROR applications.
      Sharing data is of major relevance for reflection in order to provide possibil-
  ities for comparing one’s own data with that of colleagues or a whole team. To
  account for different levels of sharing, settings (e.g. anonymised, sharing within
  the same team or department) should be very fine-grained.
      As mentioned above privacy and security are a major concern when storing
  data in the MIRROR Spaces Framework. It has to be ensured that the privacy
  settings defined by the users via different applications are always met by all
  applications, aggregations, and visualisations.
      Sharing, privacy and security settings along with other data gathered either
  explicitly or implicitly by applications, should be accessible and modifiable
  by user-friendly interfaces and visualisations provided by each MIRROR appli-
  cation. This has the advantage, that the user has full control about the data and
  has the potential to decide on a very fine-grained level, which data she wants to
  share with whom and which data should be kept private only.

  4.2    The MIRROR Integrated User Profile Application




  The MIRROR Integrate User Profile Application (MUP App) serves as a bridge
  between the MIRROR Spaces Framework and various MIRROR applications.
  It provides services for data administration as well as for directly supporting
  reflective learning. The latter is achieved by making users aware of unusual or
  significant behavioural patterns. The MUP App’s service can be used by other
  applications to show and promote reflective learning by presenting combined
  data aggregated by different applications or from different users.
      The tasks of MUP App are two-fold, providing (a) access to the data stored in
  the corresponding user profiles per user within the MIRROR Spaces Framework
  and (b) a data analysis service, which aggregates data from different applica-
  tions (on an individual level) and/or from different users (on a collaborative or
  organisational level). The aggregated data can be used to raise awareness on
  relationships between data captured from different applications, make compar-
  isons along a timeline or among different users, and finally detect patterns that
  are relevant for individual or collaborative reflection. Reasons for reflection can
  encompass the need for problem solving, decision-making, emotion regulation,
  or detection of significant deviations between the individual user and a team.
      In this first phase of the development we pursue a more general approach
  directed towards basic types of data that are comparable across different ap-
  plications. We mostly focus on statistical analysis to extract information on for
  example the number of different applications used by an individual, on providing
  a chronological overview of the applications used, on presenting the number of
  entries in various diaries, and on general information (e.g. when, how often or
  which data) was captured by each application. The data is presented on different
  types of charts, which can be selected by the user in order to ensure that the
  chart fits to the available data. In addition, the user may visualise her data in
  direct comparison with the data to other users (e.g. her team-members).
      For the second phase, we will be concentrating on the different types of
  data captured by various applications, in order to provide analysis on the com-
  bined data. For instance, combining the usage of the MoodMap App with data
  captured by KnowSelf, might show a relationship between moods and specific
  working tasks. This would lead to new insights that may be the basis for ini-
  tiating reflective learning. As an example, the left of Fig. 2 shows the hourly
  application usage history of a single user for both KnowSelf and the MoodMap
  App. The picture on the right of Fig. 2 visualises combined application specific
  data, namely the number of hourly switches between tasks or resources captured
  by KnowSelf and the corresponding mood of a user, depicted as separate lines
  for arousal (mood.energy) and valence (mood.feel) by the MoodMap App. For
  this visualization, mood values from the MoodMap App depicted in Fig. 1 are
  expressed as numbers between 0 and 100.

  5     Proof of concept

  In order to investigate the potential of a common MIRROR user profile as sup-
  port for reflective learning, we conducted a small combined user study employing
  the KnowSelf and the MoodMap App in parallel. Although we used only two
  application for this first evaluation, the MUP App is able to handle all applica-
  tions that store their data in the common user profile. Based on what we have
  learned from the separate evaluations, we see this study as first proof-of-concept
  for the MUP App. The goal was to find out whether a combined analysis of data
  from both user profiles will i) be accepted by the users, ii) enhance the boost of
  reflective learning, and iii) provide clearer insights or benefits for the single user.



  5.1     Setting


  The participating team consisted of 6 knowledge workers (3 women, 3 men), on
  average aged between 30 and 40, all of them mostly doing computer work. They
  used the KnowSelf and the MoodMap App in parallel for two weeks during work.
  Each day, either in the morning or in the evening they were asked to re-evaluate
  and reflect about their captured data and write down their insights and thoughts
  directly within one of the two applications. User activities automatically logged
  by KnowSelf could only be analysed for 5 persons due to technical reasons on
  one of the PC’s. At the end of the trial the participants were asked to fill in a
  questionnaire and to take part in a semi-structured interview.
      The questionnaire covered information regarding features and functionalities
  of the applications, usage, and reflective learning. During the interview, com-
  bined statistics (see Fig. 2) of the captured data were presented and discussed
  in order to find out the insights and benefits gained for the individual user.

  5.2    Results & Discussion

  The analysis of the log data of both applications is depicted in Fig. 3. Because
  of the small sample size only descriptive statistics are presented. As measure
  of central tendency the median is used for the same reasons. Each data point
  represents the average mood values (in terms of valence and arousal) of one
  participant in relation to the application usage and working activities (switching
  frequency and used resources). Whereas there is no trend to be derived from this
  small sample for the active use of KnowSelf, the number of moods entered per
  day seems to increase with higher valence and higher arousal values indicated
  by the participants (i.e. with a more positive mood). Switching frequency was
  measured in seconds between switching from one resource to another. Fig. 3
  (bottom) shows that higher reported valence seems to be connected to longer
  times between switches (that is a lower switching frequency) and fewer resources
  used. Interestingly, the arousal level increases with the number of used resources.




  Fig. 3. Relationship between mood (as valence and arousal), application usage and
  working activities



      Analysing the data collected via questionnaires and interviews, we can give
  first answers to the research questions:
      RQ1: Are participants interested and willing to use more than one applica-
  tion in parallel with regard to reflective learning? Ratings from 6 participants
  answering the questionnaire (using 5pt. agreement scales) indicate that there
  is an interest in getting support for time-management (Md (median) = 4) as
  well as in capturing one’s working activities, own mood, and the team mood
  (all Md =3.5). Participants found the applications easy to use, liked their visu-
  alisations, rated the presentation of information as comprehensible (all Md =4),


                                           60
Application overlapping user profiles to foster reflective learning at work - ARTEL14


  generally liked using the applications and would recommend them to colleagues
  (for both items Md =4 for KnowSelf and Md =3.5 for MMA, respectively).
      RQ2: Does the MUP App as overlapping application facilitate reflection about
  users’ working experiences and contribute to raising awareness of multiple aspects
  of their work life? The interview results revealed that the combination of data
  has high potential to trigger reflective learning although we have ambiguous
  statements in which way. One participant reflected mainly on the number of
  used applications and its relation to how the level of arousal developed over the
  day. Another participant mentioned that combined data helped her to detect a
  working pattern, which occurred especially in the morning. After reading emails
  the application switches and the arousal level increases, thus she knows that
  she started to work. Similarly, one of the participants observed that her arousal
  level is very low in the morning and increases during the day. This was a trigger
  to compare her arousal level to the average level of her colleagues and reflect
  upon eventual differences between them. An important feature mentioned by
  more than one participant was the overlapping visualisation of captured data
  on the timeline chart. Here the data was understood at one glance, which can
  facilitate reflective learning and enhance awareness of the multi aspects of their
  work life. Despite of the different approaches to reflect, for all participants the
  combination of data captured by both applications was important to understand
  the relationship between their working activities and moods.
      RQ3: Do participants perceive any individual insights or benefits for them-
  selves? Besides the findings already described in relation to RQ2, participants
  reported some additional insights they gained by reflecting on the captured data
  provided by the MUP. One participant stated that her arousal level fluctuates
  during the day. By becoming aware of the falling arousal level she decided to
  take smaller breaks to better recover during the day. Further insights concerned
  participants’ self-estimations of how they spend their working day. Whereas one
  participant stated that the captured data confirmed how she estimated the rela-
  tionship between working activities and mood development, another participant
  was rather surprised in the first place. Although she was six to seven hours in the
  office she spent only four hours in front of her computer. Only after comparing
  this awareness with her dates in her calendar, she could reproduce her day and
  explain why this happened.
      General discussion. In general, this first proof-of concept of the MIRROR In-
  tegrated User Profile indicates that such overlapping visualisations can facilitate
  individual reflective learning and raise overall awareness of users’ work life. All six
  participants used the combined data to reflect on how their working activities are
  related to mood changes and could gain some individual insights. Nevertheless
  there a still some points which need further discussion. While KnowSelf captures
  automatically the resources and applications used on the PC, the moods need
  to be inserted manually. Having to repeatedly insert a mood in a web based
  application can distract from the normal working process. One recommenda-
  tion to alleviate this distraction was to add five different smileys in the system
  tray to facilitate the mood capturing. Another point for consideration is the

  optimal time for reflection. All of the participants perceived the combination of
  the data captured by the MoodMap App and KnowSelf as useful, because they
  could check at all times what they were doing during work and how they felt.
  However, one participant stated that it was not very useful to reflect on how
  she felt three days ago, but that it was more interesting to become aware of
  her mood in relation to her work directly while working. For other participants
  especially the knowledge of how they felt for example three days ago was very
  important. Especially when the mood could be directly related to the mood
  note, used applications or used resources. A rather interesting statement from
  one of the participants was that her working tasks did not influence her mood
  at all. With respect to the visualisations, the interviews showed that different
  types of aggregating the data would be useful, so that users could indicate their
  individual preferences, e.g. to visualise the data along a timeline, to aggregate
  on an hourly basis, or to offer a summarising view in form a pie chart.
      In summary the MUP App provides new visualisations based on data cap-
  tured by different applications, and therefore offers a multitude of new possibili-
  ties for individual interpretations. In our proof of concept, we only combined data
  of two applications, but also within this small setting we received different ap-
  proaches on how the participants interpreted the captured data for themselves
  and what they learned from it. We also mentioned some shortcomings which
  must be taken into consideration when proceeding with the development of the
  MUP App. Nevertheless, our findings encourage the assumption that combining
  data of more than two applications, leads to more meaningful possibilities to
  interpret the data and to gain more diverse insights for oneself.


  6    Conclusions and Outlook

  In this paper we presented the new MIRROR integrated User Profile Applica-
  tion, which aims at supporting reflective learning at work. Based on the results
  from previous user studies, which evaluated single applications, we derived es-
  sential requirements for the development of the MUP App and implemented a
  first prototype. Results from a first small evaluation regarding the parallel usage
  of two applications indicate that combining data captured by different appli-
  cations, analysing and visualising them together can further facilitate reflective
  learning. Furthermore, it can also enhance awareness of the work life by leading
  the users to get more diverse insights about themselves. Of course, after this first
  proof-of-concept, user-studies with larger samples and more applications need to
  follow. Thus, our future work will focus on the integration of further applica-
  tions developed within the MIRROR project into the MUP App. The goal is to
  provide different variants of visualising combined data and more sophisticated
  ways to provide guidance for reflective learning. For example, Fig. 4 combines
  KnowSelf data with corresponding geo location data captured by another MIR-
  ROR App. Thus it makes you aware of your working activities in relation to
  your working places (e.g. customer visits or travel activities) and can provide
  more triggers for reflective learning.
