Abstract. Children with exercise-induced asthma face several challenges in their
daily life, which can improve by proper self-management practices. AIRplay
combines biomedical sensing with gamified environments to improve physical
conditioning and self-management of asthma among children aged 7 to 9 years
old. The goal is to develop a proof-of-concept of coaching application that mon-
itors physical activity of a young asthma patient, provide feedback based on this
activity data, and integrates this application with an interactive playground to
improve fitness. We discuss three areas where we can improve the current man-
agement of asthma among children based on literature and interviews with health
care professionals. We present the coaching application and the interactive play-
ground game, followed by a discussion where we discuss the current proof-of-
concept using the Persuasive Design Model (PSD). We also foresee some chal-
lenges for future development and research.

1 Introduction
Asthma is the most common chronic disease in childhood. In the Netherlands the num-
ber of people with asthma is well over 443.000 and is steadily increasing [1]. Recent
estimates show that about 5% of children (4-11 years old) in the Netherlands have to
cope with asthma [2]. Asthma is an inflammatory disease of the airways of the lungs,
characterized by variable and recurring symptoms, including episodes of wheezing,
coughing, chest tightness, and shortness of breath. Exercise-induced asthma (EIA) af-
fects 70-90% of the asthmatic children [3]. EIA can deter children from participating
in regular physical activity and eventually lead to dropping out of play and sports [4].
Many environmental factors have been associated with asthma’s development and ex-
acerbation, such as house dust mite, air pollution, tobacco smoke, and perfume. How-
ever, the extent to which each one of these factors induces exacerbation is highly per-
sonal [4]. Children must learn about how to anticipate triggers/circumstances that en-
hance their EIA. Medication adherence, physical exercising and education –aimed at

improving the ability of children to control their asthma themselves– are crucial for
successful asthma control.
From interviews with medical experts (three pediatricians with experience in the care
of asthmatic patients) and from the literature we identified three main areas where tech-
nology could be used to improve the current management of asthma among children.
The informal semi-structured interviews were performed in several iterations, three
meetings were accompanied with presentations to explain the problem areas, care chal-
lenges, and opportunities for technological enhanced asthmatic care. First, there is the
importance of the physical conditioning of the children. Systematic- and meta-analysis
of the literature showed no consensus whether children with asthma are differently en-
gaged in physical activity than children without asthma [5, 6]. However, it is generally
accepted that maintaining active lifestyle is of utmost importance for management of
asthma symptoms, and therefore children with controlled asthma must be encouraged
to engage in physical activity [7,8]. Children with uncontrolled asthma are less fit. Un-
controlled asthma is associated with less time spent in intensive physical activity, re-
sulting in reduced fitness [9]. As a consequence, compared to their healthy peers chil-
dren with asthma are more likely to be overweight, bringing additional health related
problems [6]. Children with asthma report experiencing limitations related to various
activities that involve a physical effort (such as playing outside, carrying heavy weights
or swimming) [4]. Technology-based interventions might support children in achieving
the recommended levels of physical activity at their own pace, thereby increasing their
asthma control.
A second area is the use and adherence to medication. Adherence to medication pre-
venting asthma symptoms has been associated with better disease control. Non- or
suboptimal adherence is associated with poorer disease control and increase in asthma
morbidity and mortality [10].
Studies examining adherence rates with preventive medication by asthmatic children
have reported average adherence rates of 50% to 77% [11]. Learning the best practices
on how and when to take medication is a crucial step to improve self-management of
asthma, which can be supported by technology.
The third area identified in which technology can support self-management of
asthma relates to the social, emotional, and mental aspects. Children with asthma do
feel they are different (less popular) and lonely because of their disease and the medi-
cation they have to take. They experience limitations during (sport) activities with peers
and are being bullied, left out and not believed by their peers [4]. Technology might
support social integration of children with asthma by enabling initiatives that require
cooperation between children within the same group.
In childhood asthma there is critically low treatment adherence and there is treatment
failure which is resulting in high costs and low Quality of Life (QoL). Self-management
is needed for optimal asthma control (and life-long health consumption). Current
healthcare is not sufficiently supporting children in acquiring self-management skills
because of lack of support by health professionals and a lack of insight among parents
and children.

Initial studies on technology-based interventions to promote self-management of
asthma focusing on education and medication adherence among the pediatric popula-
tion have suggested promising results [12]. Studies indicate that gamification might
improve the self-management of chronic illnesses, such as diabetes [13,14]. However,
engagement with the technology, which often asks for additional activities from the
user, diminishes over time. The challenge is thus to keep the user engaged with the
system in the long run. The combination of gamification and virtual coaching, is ex-
pected to have a positive impact on the patient’s self-management skills, knowledge,
and adherence to their health care regime.
2 The AIRplay Concept
The AIRplay project aims to improve the physical conditioning of children with asthma
(7-9 years old) by combining mobile monitoring of daily physical activity with behav-
ior change strategies in gamification elements. That is to say, that we focus on the iden-
tified problem areas of physical conditioning and social/emotional aspects, and at least
for now not focus on medication adherence. This in short is the context of our AIRplay
project: a collaboration between healthcare professionals (Medisch Spectrum Twente
and Ziekenhuisgroep Twente) and researchers from the University of Twente in the
fields of biomedical signals and human computer interaction.
Pervasive technology makes it possible to track physical activity, using affordable
sensors that can be worn throughout the user’s daily life. In combination with tablets
and other mobile devices that provide visual feedback, this allows for improving insight
into children’s own behavior. In order to persuade children to change their behavior,
improving their insight and also encouraging physical activity, we incorporate several
coaching and gamification elements into a combination of pervasive technologies.
We are currently working on an implementation of these technologies, consisting of
three elements 1) a simple wearable physical activity sensor, 2) a tablet application, and
3) an interactive playground. With this combination we go beyond the screen, unlike
other exertion games we attempt to change behavior beyond the game play itself (cf
[15]), and target the three areas identified in interviews and the literature: the social,
emotional, and mental aspects of the children; their fitness; and their adherence to and
use of medication.
For one, in this project we choose to both address healthy children and children with
asthma together, in a similar manner. We view that children with asthma should not be
stigmatized but should be included in social play behavior (according to their capabili-
ties), and preferably be challenged to increase their amount of play with others, which
in turn can help to improve their emotional and mental aspects.
We also target improvement of the fitness of the children. Each child will be pro-
vided with a personal daily physical activity goal, in the form of a to be attained number
of steps for that day. The target number of steps will be tailored based on their capabil-
ities, and the amount of steps counted by the sensor is send to the tablet application.

and a tip of the day (bottom right)
The application will show which percentage of their goal they reached, and in this
way tries to stimulate to move more and increase their fitness. A ranking between chil-
dren will be made based on this percentage. Another element we are incorporating, is
to reward children with additional abilities in another game, that is physically present
in their world. This game is played on an interactive playground that could be placed
at a school. This playground, consists of an interactive floor projection of about 5 by 5
meter, that responds to players positions as measured by top-down Kinects, see Figure
1. This system was provided to us and allows users to walk in and play without addi-
tional calibration or devices, for more detail on the system we refer to [16].
The application will also provide useful information and tips regarding the medica-
tion, but only for the children with asthma. This could increase the awareness about
their medication, and in this way also help to improve adherence and use of medication.
3 The Playground Game
We created a game on the playground where children have to use their projected avatar
on the floor to either tag an opponent or to catch an opponent, see Figure 2 for a depic-
tion of the game mechanics.
There is a ‘safe house’ that is located in a corner, and switches to another corner
every 10 seconds. This ‘safe house’ can be used to take a break from the game, players
cannot get caught or tagged whilst inside, this might allow a child (especially those
useful for those with asthma) to take a deep breath or even take medication, if neces-
sary. In order to materialize reaching their daily physical activity goals, children are
rewarded by unlocking additional levels in the playground game, for instance a level
where both teams are able to catch each other.
3.1 Playground Play Sessions
About 80 children played with the playground game in four iterations. In total in the
first and second iteration combined about 60 children (6-12 years old) participated as
part of field trip of their primary school to the university premises. In the first iteration

children were slightly older (10-12 years old) than during the second iteration (6-10
years old). The third iteration involved 7 healthy children (7-9 years old) and the fourth
and last iteration included 8 children with asthma (7-12 years old), playing in the play-
ground. During the four sessions children showed evidence of physical fatigue, as could
be witnessed by their red faces and fast breathing rate. The children did have trouble
understanding the game, and additional explanation was given during the games. None-
theless, children very much liked to play in the playground, as they often asked us to
play again, and as was witnessed by the remarks made during the game.
4 Discussion
Although we did not explicitly start with using a framework like Persuasive Systems
Design [17], having several years of experience in persuasive technology design, we
can still clearly see that the system design embeds several principles of the PSD frame-
work. Here we use the PSD in a more post-hoc formative evaluation manner, and focus
on the persuasive design features of the framework. Many principles are already incor-
porated to some extend but other principles of the framework provide insightful sug-
gestions. We mention some of these below.
For the Primary Task Support principles it is clear that we used reduction, tailoring,
personalization, self-monitoring, and rehearsal. Regarding the principle of tunneling,
we do not yet specify how the activity goals will be changed over time, and how the
hints will be used from a more holistic point of view about medication intake. Further-
more, steering behavior in the playground –changing in-game behavior in a more di-
rected way with the introduction of new game elements– could also be used as an in-
teresting tunneling approach to further improve physical activity [18]. Also, simulation
is not yet incorporated, one might foresee virtual players on the playground (simulating
a certain attainable improvement of a player), or exemplify in the app how medication
intake might change performance.
Many principles regarding Dialogue Support are also taken into account to some
extend: suggestions, similarity, liking, and the social role. Other elements also provide
interesting possible additions. Praise, although the winning team of the playground

game is always shown and praised, the app could use some more praising elements
when a user reaches a personal goal. Rewards, we tried to provide meaningful rewards
by having impact (unlocking levels) in a game separate from the app, akin to an ap-
proach applied for digital games were achievements in one game resulted in rewards
for another [19]. Power-ups at the start of a game, or more aesthetic rewards both in the
app and the playground could also be considered. Reminders, the goals are visualized
and can serve as a passive reminder (more in the form of self-monitoring), however the
intended active type of reminders are not yet specified and could be of additional value.
Regarding System Credibility Support elements the systems clearly has a level of
trustworthiness, expertise, authority, third-party endorsements, and surface credibility
(mainly due to the help of the health care professionals involved in the project). The
principle of real-world feel suggests it would be worthwhile to also include possibilities
to contact the doctors about tips in the app. Although some third-party endorsements
are inevitably linked with the cooperation of doctors in the project, more endorsements
for instance of patient interests groups, and the hospitals (e.g. logos) could be helpful
for the persuasive power and implementation of the system. The principle of verifiabil-
ity suggests that further information and sources could be provided in the form of links,
for instance regarding the hints or the level of the set personalized goals.
The systems also include many Social Support principles, mainly due to the ranking
system and social play aspects: social learning, social comparison, cooperation, com-
petition, and recognition. The latter could also be improved by creative appraisal of
behavior similar to achievements in popular games: ”Great you are this week’s busy
boots boy” or by using our contacts to show images, videos, and quotes of well-known
sport heroes. Regarding social facilitation as well as normative influence, it is also in-
teresting that we plan to place a playground at the hospital waiting room, where multi-
ple children with asthma can play the game together, perhaps even together with parents
and a passing-by doctor, which might help to increase the norm for amount of activity.
We can conclude that the PSD framework can efficiently be used for providing many
valuable suggestions, even when an app is linked to a playground. Once we incorporate
some of these suggestions, we still remain with the challenge to evaluate the level of
success in a more summative way based on actual use. For instance, the scope of the
project does not allow for doing a more thoroughly planned RCT, or doing the required
long term study (e.g. 3+ months). At the same time we expect that the novelty, and
tendency of children seen previous research to be positive during evaluations, will be
of influence and that for this and other reasons the long term adherence could drop
compared to results from simple user tests. A challenge of the multi-disciplinary work
is that we need to design both creative solutions while addressing appropriate targets.
All members of the team should work closely together in order to provide valuable,
new, and refreshing persuasive technologies. Furthermore, as is suggested with the PSD
model, to do so not only the medical professionals need to understand aspects of tech-
nological concepts, the HCI professionals also need to understand the user and context
of use. Another challenge beyond the design and showing some scientific proof will be
to actually incorporate into daily practice. Several possible advantages could help to
facility this process such as an entertaining and social environment to stimulate activity
while providing opportunities for automatic behavior analysis (cf [16]). Furthermore,

we believe that the close cooperation with health care professionals from two different
hospitals could be a persuasive element for other interested groups.
5 Conclusion
In this paper we present our work on the AIRPlay project. The goal of the project was
to develop a proof-of-concept which combines a coaching application that is able to
monitor physical activity of a young asthma patient, provide feedback based on this
activity data, and integrates this application with an interactive playground. The inte-
gration of the coaching application with the interactive playground allows us to create
a fun way in which children can interact with the system to improve the current man-
agement of asthma among children. The AIRPlay proof-of-concept can be improved
by implementing knowledge from the field of persuasive technology and behavior
change support systems in a more structured way. The PSD model can be used to im-
prove or add features to the system to maximize the impact of the system on the man-
agement of asthma among children or to apply and translate the concept into applica-
tions for other (chronic) conditions. Interesting topics to explore are the way how
knowledge from these fields can help to evaluate the system and to design a next ver-
sion of the AIRPlay system.
