      <abstract>
        <p>Hearing impairment was indicated as the second largest proven deficiency in world population. People with such disabilities face many obstacles in their communication and interaction with listeners, even with equal level of cognitive development. Collaborative tools offer the possibility to improve the interaction between listeners and hearing impaired subjects. This study presents an approach to support this type of interaction aimed to augment the participation of hearing impaired in collective activities. The approach has been materialized in a collaborative writing tool on which participants from both categories work together to produce a common document. The approach was evaluated by means of an experiment conducted with listeners and hearing impaired students in a learning environment. Analysis of the results obtained in the experiment show that the collaborative writing enhanced the interaction and contributes to a more harmonious and real coexistence among listeners and hearing impaired.</p>

      <title>Introduction</title>
      <p>
        The WHO (World Health Organization) estimates that
10% of the population of developed countries is
composed of people with a disability. In developing
countries this rate is estimated between 12 and 15%.
According to
        <xref ref-type="bibr" rid="ref17">Smith (2003)</xref>
        among the world's population
under the age of 15, approximately 62 million have
permanent and hearing loss.
        <xref ref-type="bibr" rid="ref16">Olusanya (2005)</xref>
        indicated
that two-thirds (41 million people), live in developing
countries. The incidence of hearing loss in newborns,
according to
        <xref ref-type="bibr" rid="ref21">White (1993)</xref>
        is 1.5 to 5.95 per 1000 births.
In the literature, we also found that presbycusis - hearing
loss due to age - is the main cause of hearing impairment
in the elderly, with an incidence of about 30% of the
population over 65 years of age. The noise, especially in
the workplace, is appointed as the second leading cause
of sensorineural hearing loss among adults. Hearing
impairment affects five percent of adult population in
U.S., according to NCHS - National Center for Health
Statistics. In Brazil Hearing impairment stands out as the
second largest proven deficiency in Brazilian population.
      </p>
      <p>Hearing impairment is characterized by total or partial
loss of ability to hear. It manifests as mild to moderate
hearing loss and severe or profound deafness. It is
considered one of the main disorders that can interfere
with language development and speech. According to the</p>
      <p>American Speech-Language-Hearing Association it
represents 60% of communication disorders. Thus, this
difficulty interferes directly in the interaction with
hearing individuals.</p>
      <p>
        People with hearing impairment may have affected
their learning and their integral development, since
language plays an essential role in perceptual
organization and the receipt and structuring of
information, learning and social interactions of human
beings. For
        <xref ref-type="bibr" rid="ref9">Gatto (2007)</xref>
        the hearing is a pre-requisite for
development and acquisition of language. Hearing and
language functions are interrelated and interdependent.
      </p>
      <p>Despite these data, the hearing impaired subjects are
not easily recognized in society as people who have
distinct needs. This recognition occurs when they need to
communicate, because of the difficulty they present using
oral colloquial language. This difficulty directly
interferes in the interaction with listeners.</p>
      <p>
        According to
        <xref ref-type="bibr" rid="ref5">Capovilla (1998)</xref>
        , technology should aim
to solve human problems and the solution should not
discriminate any type of person. It should look
universally the situations faced by humans, assuring them
full participation in the environment they live. Thus, we
should also use technology to help those who have
disabilities in having a life as normal as possible.
      </p>
      <p>
        New technologies offer good alternatives to facilitate
interaction among individuals communication. In this
scenario, there is a powerful mechanism of interaction
among individuals: the collaborative writing. This
mechanism allows the diversity of knowledge and skills
and helps individuals who have difficulty to formalize
certain knowledge or build a solution alone. Thus,
problems can be better solved by a group of individuals
working collaboratively, than by a single individual
        <xref ref-type="bibr" rid="ref10">(Howard, 2000)</xref>
        .
      </p>
      <p>The aim of this study is to analyze the contribution that
collaborative writing can offer to improve the interaction
among hearing impaired and listeners. To support this
claim an experiment is proposed by mixing in each group
listeners and hearing impaired subjects enrolled in a
common task: the production of a document in a
collaborative way.</p>
      <p>This paper is divided as follows: Section 2 describes
the communication aspects of hearing impaired persons.
Section 3 presents the collaborative writing process and
its features that help collaboration among individuals.
Section 4 describes an experiment conducted to evaluate
the benefits of technology supported collaboration in
overcoming individual deficiencies. Section 5 analyzes
the results of this experiment and Section 6 presents the
conclusions.</p>

      <title>Hearing Impaired Communication</title>
      <p>Social networking has had a clear impact in the world,
connecting people to find and create new friends, share
ideas and organize events. Although social interactions
are activities that have always happened naturally, on the
Internet this process becomes more open and fluid
affecting the way people interact. These processes find
their "natural" environment on the Internet, where social
collaboration and dissemination of information is
facilitated by recent innovations.</p>
      <p>
        According to
        <xref ref-type="bibr" rid="ref1">Adams (2008)</xref>
        “The driving social
behaviour now though is collaboration. The networks are
established and have become part of the scenery. As
people become confident social agents in online networks
they begin to act, to organise, to create.”
      </p>
      <p>Collaboration in social cooperation between
individuals may have different objectives, both to make
life more pleasant and to supply their deficiencies. The
computer is seen as pro-cognitive activity of structuring
knowledge representations and also on emotional
development (Oliveira, 1996). It is a resource for children
with learning difficulties despite its shortcomings and
limitations develop their cognitive capabilities and
possibilities of their own.</p>
      <p>
        Hearing impairment is a kind of sensorial restriction,
whose main symptom is an atypical response to the sound
stimulus, being classified accordingly to the degree of
hearing loss
        <xref ref-type="bibr" rid="ref4">(Marchesi, 1996)</xref>
        . However,
        <xref ref-type="bibr" rid="ref6">Ciccone (1996)</xref>
        states that the hearing impaired is an individual with
potential normal cognitive, although the hearing loss
implies, often, in serious obstacles to its interaction with
listeners.
      </p>
      <p>
        According to
        <xref ref-type="bibr" rid="ref7">Couto-Lenzi (1997)</xref>
        , in interaction with
hearing impaired, listeners should consider that among
the hearing impaired, some are born with hearing loss
and others lose their hearing after birth, during the
prelinguistic stage or after learning mother tongue, resulting
then, in different prognosis in the learning process and
development of writing.
      </p>
      <p>This distinction becomes relevant when interacting
with deaf people since it implies a greater or lesser
degree of difficulty in the use of colloquial language
oralized, practiced by individuals listeners.</p>
      <p>In accordance to Northern and Downs (1999), any
symbols that emerge in society are conditioned to a
language of listeners. In the hearing impaired these
symbols lose their meaning and sign language will
always be the most prevalent.</p>
      <p>This difficulty of interaction may also be reflected in
collaborative writing, since the hearing perception is
correlated with the acquisition of written language, due to
the relationship of sounds to the graphic symbols that
characterize the natural language. Thus, the formal
writing produced by deaf people is based on a different
way of thinking and basically sign languages.</p>
      <p>
        As
        <xref ref-type="bibr" rid="ref3">Gotti (1991)</xref>
        affirms, the phrase structure of the
hearing impaired is disjointed, without connecting
elements, often without verbs, due the deficiency in logic.
      </p>
      <p>This is one of the major challenges of the interaction
between deaf and hearing people through writing.</p>
      <p>
        There are studies that link the technology-mediated
communication as a facilitator of integration. As reported
in the work of
        <xref ref-type="bibr" rid="ref18">Santarosa (2003)</xref>
        with deaf and blind
people, that integration is provided communication
interfaces to facilitate and support the interaction among
these subjects. , with evidence from a blind person that
corresponded with a colleague, using technological
resources, not knowing that this was deaf. In another
study
        <xref ref-type="bibr" rid="ref19">Santarosa (2002)</xref>
        stresses that the use of electronic
means, primarily e-mail, allows the advance in
development of the deaf, with a view to written
communication and social interaction.
      </p>
    </sec>
    <sec id="sec-3">
      <title>Collaborative Writing</title>
      <p>The human is in continuous biological development,
influenced and influencing the social environment where
he lives and exercises their interactions. He has natural
biological altruism as an individual and need to be part of
human groups and to operate by consensus with them.
This need acts as a motivating factor in interactions with
other individuals and thus the hearing impaired seeks to
overcome the difficulties of interaction. For this, the use
of new technologies that facilitate this process is seen as
a good alternative.</p>
      <p>Many efforts have been made to develop solutions to
facilitate this process. Among them, we highlight the
development of multimodal interfaces, the use of tools
that make the association between text and video and
software that seek to provide collaborative practices, the
groupware, more precisely the collaborative editors,
object of this study.</p>
      <p>
        The basic development concept in multimodal
interfaces for the disabled is the idea of modality
replacement, which is the use of information originating
from various modalities to compensate for the missing
input modality of the users
        <xref ref-type="bibr" rid="ref13">(Moustakas, 2006)</xref>
        .
      </p>
      <p>The tools that make the association between text and
videos can be used to associate texts in the mother tongue
videos with the same text into sign language, accessible
to the hearing impaired.</p>
      <p>Among the groupware, we highlight the cooperative
editors that allow the creation of texts in cooperation with
two or more users.</p>
      <p>
        Editing documents collaboratively or jointly with
others is a common task. Often, the documents we
produce are reviewed by someone or receive some kind
of contribution
        <xref ref-type="bibr" rid="ref20">(Tammaro and Mosier, 1997)</xref>
        . The
collaborative writing of documents allows participants to
interact during the construction of texts, generating new
ideas and modifying them still of development work
        <xref ref-type="bibr" rid="ref10">(Howard, 2000)</xref>
        . Thus, participants always have the
possibility to suffer interference in textual exposition of
his ideas, creating a new text composed by several
participants. This context of interaction among
participants in a cooperative process of editing promotes
acceptance of differences that exist between individuals
and could be further explored when we think of
interaction between listeners and deaf people.
Besides promoting greater interaction among
coauthors, collaborative editing environments can promote
critical thinking, helping people to learn from each other
and strengthen the social relationships of those who write
together
        <xref ref-type="bibr" rid="ref12">(Mailhiot, 1968)</xref>
        . Such benefits could also be
targeted to facilitate interaction between deaf and
hearing. Thereafter, the editing process could become a
cooperative way for the development of a sense of
cooperation and acceptance of hearing impaired by
listeners.
      </p>
      <p>However, it is necessary not only thinking on the
benefits or problems that this approach represents, but
also about the changes in the perception of reality and the
changes that occur even in the way of writing. If writing
together with individuals who use the same grammatical
structure of language can become a complex process,
with individuals who use different grammatical structures
the level of complexity may increase further.</p>
      <p>In contrast, once aroused the senses to the value of
cooperation or interaction and understanding its validity,
it will never be forgotten by an individual. Thus, the
benefits of this interaction could overcome the difficulties
presented.</p>
      <p>
        These characteristics can become great allies in this
process of interaction through collaborative writing.
According to
        <xref ref-type="bibr" rid="ref8">Ellis, Gibbs and Rein (1991</xref>
        ), until they
have established interpersonal relationships based on
acceptance, interdependence and complementarity, the
groups are not ready to develop a cooperative work.

      <title>The Experiment</title>
      <p>Aiming to examine the contribution that collaborative
writing can offer to improve the interaction between deaf
and hearing people, was conducted an experiment that
involved the production of a text in a cooperative manner
between these two types of co-authors.</p>
      <p>The experiment was conducted in the computer lab of
the School Professor Olga Teixeira de Oliveira, pole of
inclusion of students with hearing impairment located in
Duque de Caxias in Rio de Janeiro.</p>
      <p>The moderator of this experiment is a school teacher,
who initially explained to the participants the process of
collaborative writing. On this part of the experiment, the
moderator writes: "They had the opportunity to better
understand the reality of two worlds (hearing world and
deaf world). Students listeners were impressed with the
writing of deaf students, then had to explain about this
condition of the deaf colleagues. In short, I explained that
Libras (Brazilian Sign Language) is the first language of
the deaf person and written Portuguese is a second
language, and how they think in Libras have difficulty in
organizing writing with the grammatical structure of
Portuguese. But that does not make them worse than the
listeners, but different." LM.</p>
      <sec id="sec-4-1">
        <title>The Tool Used in the Experiment</title>
        <p>
          According to
          <xref ref-type="bibr" rid="ref20">Tammaro et al. (1997)</xref>
          , a cooperative editor
should provide mechanisms to assist in the interaction
that occurs when people are working collaboratively on
editing documents. Thus, their characteristics should
include:
 Be flexible to meet the usability needs of users;
 Allow editing of synchronously and
asynchronously;
 Maintaining the integrity of the document being
edited by different users and the possibility of merging
to combine the contributions;
 Have an access policy that defines roles and
their permissions and restrictions on the handling of
documents;
 Multiple versions of a document should be
maintained so that someone can come back with a
version where appropriate. It is also important that the
record which was the collaboration of each co-author;
 It is important to offer options for comment
where the user can make their comments to a document
or specific parts of it;
 It is also important to allow communication
between the co-authors, so that they can discuss and
exchange ideas;
 Allow the creation of a workflow for the
construction of the document and publication of the
same co-authors;
 When a document is created and shared, users
who have access to it should be notified;
 Similarly, when a document is changed, all users
that share should be alerted; and
 Provide monitoring a document allowing, for
example, who is now visiting, who never accessed etc.
        </p>
        <p>With the aim of using a tool that would meet the
largest possible number of the above characteristics, was
chosen editor GoogleDocs to be used in the
experiment. It needs only a registration email and is a
system for easy access.</p>
        <p>Also, lets you invite others to join the work, being a
tool of collective works, which also offers basic editing
tasks with a desktop simple and easy to understand, also
allows these operations can be performed in conjunction
with other participants in real time, and, provides a
synchronous or asynchronous editing.</p>
        <p>
          According to
          <xref ref-type="bibr" rid="ref11">Machado (2009)</xref>
          , this tool fosters
interaction, exchange of ideas and collective production
of texts. The exchanges can be established positively
enabling creativity, critical thinking, responsibility and
collaboration.
        </p>
        <p>
          Google Docs provides ease of use, storage and online
editing of files, access via the browser on multiple
platforms, gratuity, requires no software installation and
simple interface and be accessible over the web

      <sec id="sec-4-2">
        <title>Development</title>
        <p>For the development of the experimental parameters were
considered, as described below:
 The chosen theme for the activity;
 The age group of invited participants: 13-18
years old;
 The theme of the text to be produced: "A whole
country in the World Cup." The choice of this subject
consider the proximity of the 2010 World Cup and also
the age group of participants. The theme is easy to
understand and refers to a subject widely reported and
discussed in the media, serving as a motivating factor
for the interaction of participants;
 The number of participants: ten co-authors, five
and five deaf listeners;
 All deaf participants are congenital deafness,
and they were born with hearing loss were illiterate and
without the reference of phrasal constructions and
sounds of their own natural language;
 The participants had a period of seven days to
build the text in a collaborative way.</p>
        <p>Following the construction of the text in
GoogleDocs, we observed that the interaction occurred
both synchronously, whereas some young people interact
within their school environment in the same place and at
the same time, as asynchronous distributed, because
other interactions were carried out at different times and
places.</p>
        <p>Regarding to the contributions of the co-authors, was
noted that participants complemented and not changed
the text of the other participants, i.e., took care not to
modify the text of another. On that point, the moderator
reports: "Initially I was a little worried about the way that
listener students understand the writing of deaf
colleagues. But, after the explanation, I noted the positive
reaction of the group. Demonstrated a willingness to help
and decided not to correct spelling and concordance of
texts developed by deaf students. And on the other hand,
the deaf were more attentive to the listener colleagues’
writing, and sometimes tried to correct himself." LM.</p>
        <p>The participants answered a questionnaire consisting of
eight questions, which together with the historical
contribution of the participants contributed to the tool
used to analyze the following measures:
 The level of knowledge of participants on the
theme chosen for the preparation of the text;
 The degree of difficulty in using the tool;
 The level of interaction between participants in
the collaborative writing process;
 The level of interaction between listeners and
hearing impaired.</p>

    <sec id="sec-5">
      <title>Analysis of Results</title>
      <p>Data collected through the questionnaire, as well as the
history contributions of participants in the cooperative
editor used, were analyzed in a qualitative way. Thus, it
was possible to consider whether the collaborative
writing process developed by the group contributed to
improve the interaction among hearing impaired and
Listeners who participated in the experiment.</p>
      <p>As shown in Figure 1, the majority of participants, both
listeners as hearing impaired, has at least some
knowledge on the topic "A whole country in the World
Cup", chosen for the construction of the text. This
indicates that the level of knowledge of participants on
the topic facilitated the group interaction in this
experiment.</p>
      <p>Figure 1 also shows that most listeners had no
difficulty in using the tool and the majority of hearing
impaired had little or no difficulty. It was possible to note
that facility presented in using the chosen tool for this
experiment contributed to the group interaction during
the editing cooperative process.</p>
      <p>It was also noted that the difficulty that hearing
impaired present to organize the writing, using the
Portuguese grammatical structure, can be unknown even
by listeners of the same social group, as is noted in the
following testimony of a co- authors: "I didn’t know that
deaf people write so differently." MVS (Listener). In this
aspect, the experiment allowed the participants
coauthors could learn about the different ways to use their
mother tongue.</p>
      <p>Participants of the experiment lso report that has never
participated in a collaborative writing process. However,
all claim that the process of writing together facilitated
the construction of the text. Regardless of the group is
formed by people with different phrasal constructions,
they note that the collective knowledge that allowed
everyone to have gain knowledge on the topic: "They
spent more info for those who had little knowledge of the
subject." JHM (Listener). "Knowing the subject matter
and passing colleagues." TF (Deaf). These reports
demonstrate that the differences in the construction of
phrases and expressions did not affect the group
interaction.</p>
      <p>Most deaf people said that interaction with the listeners
was good and all the listeners said that interaction with
the hearing impaired was excellent, as shown in Figure
01. This indicates a great level of acceptance and
understanding of the listeners with respect to the
difficulties in writing of the hearing impaired, as reported
by the participants: "To know a little deaf." LR
(Listener). "Listeners and deaf good relationship." SGO
(Deaf).</p>
      <p>It was observed that the collaborative writing process
not only facilitated the group interaction in this activity,
but also promoted greater acceptance of hearing impaired
and contributed to the growth of the social bond, as
reported by the participants: "Learn to write better
listener colleague." TF (Deaf). "Because I met so my deaf
friends." SK (Listener). "As one completes the other."
DAO (Deaf).</p>
    </sec>
    <sec id="sec-6">
      <title>Conclusions</title>
      <p>The experiment has achieved the goal of simulating a real
situation of interaction between listeners and the hearing
impaired. According to the moderator, "this experiment
has enabled work on the theme World Cup, writing,
creativity, respect and appreciation of their own
productions and those of their colleagues." This report
confirms that it is very important that the effects of oral
language on cognition are not overvalued by listeners
about the performance of the hearing impaired, which
would complicate its inclusion and real chances of a
productive interaction. However, the experiment proved
that through writing cooperative deaf participants were
able to interact with listeners and together build a textual
product, despite their differences in the use of the
grammatical structure of Portuguese Language.</p>
      <p>Regarding the phrasal construction, was observed in
the experiment that participants did not change the
sentences presented differently. This confirms that
although there is significant difference in the level of
management of instrumental language, the process of
communication between participants was not harmed.
This validates the collaborative writing as a mechanism
of interaction between deaf and hearing, and shows that
this mechanism favored a greater acceptance of
differences among individuals and helped to improve the
cognitive development of participants. On that point, the
moderator noted: "The result achieved was excellent, and
I know that through this tool GoogleDocs students can
further develop their written productions. I consider this
tool as another way in the pursuit of cognitive
development of my students, and enjoyed both working
with her, I'm thinking of developing a job with a new
group, involving all students." LM. This report shows
that through this experiment it was possible to extend the
possibilities of interaction between deaf and hearing
through collaborative writing.</p>
      <p>The reports presented in this paper guides analyze of
results and confirm the acceptance of the collaborative
work proposed by the experiment. They clearly show that
the experiment helped to improve the interaction between
deaf and listener not only in the construction of the text,
but in building a more harmonious and real coexistence.</p>
      <sec id="sec-6-1">
        <title>Future Work</title>
        <p>This work does not exhaust the subject and, therefore,
points out some future work that may be performed in
order to contribute more to the interaction between
hearing and deaf people using collaborative editing:
• Conduct the experiment with a control group, allowing
comparison of results obtained by the groups, enriching
the analysis;
• Measure the level of contribution of the participants in
relation to the interaction of the texts submitted by others,
checking with the resources offered by the tool for
collaborative editing, the ability to follow through the
recording of interactions made, which can later be
measured and analyzed;
• Conduct the experiment with a larger group of
participants, allowing also perform a quantitative analysis
of the subjects addressed in this work.</p>
