Inclusive Participatory Design: Guidelines for
and Reflections on Involving Users with
Disabilities in Design of Assistive
Technologies
Dr Jo Lumsden, Aston University  [email protected]
introduction…
>500 million people around the world have some form of
recognised disability associated with a mental, physical, or
sensory deficiency
scope for IT-based assistive technologies to enhance
independence & quality of life…
…but this requires researchers to invest time & effort in
familiarising themselves with the domain of, needs, and specific
capabilities of users with given disabilities  challenging!
call for direct involvement of end users in design process & more
systematic approaches for doing this
introduction contd.…
conventional participatory user-centred design (UCD) methods
can be challenging to apply when engaging individuals with
impairments…
…but imperative that such methods are employed because it is
otherwise largely impossible for designers to understand users’
needs, appreciate implications of users’ capabilities, and design
appropriately
existing mobile assistive technology design for visually impaired 
little evidence of direct involvement of end users
UCD, especially participatory design (PD), under-utilised in
healthcare technology generation (especially for design)…
…general lack of process elucidation in most existing studies
focus of this talk…
outline some challenges of inclusive participatory design for
assistive technologies
present collated set of guidelines
reflect on application of the guidelines for design aspects in terms
of two case studies
discuss remaining challenges for participatory design approaches
challenges of inclusive PD…
need a good understanding of users’ needs and abilities
complex given range of aspects of cognitive, physical and sensory
capabilities, not just those related to target disability
user attitudes to technology and own disability
impact of degenerative disorders over time
…and understanding/relating to the above can be hard for
researchers
multidisciplinary approaches increasing, where domain experts
included to compensate for limited disability knowledge of
technical team
included as member of the research team, liaison or
representative
challenges of inclusive PD contd.…
available population of target users is relatively small  finding &
recruiting participants can be hard
lack of homogeneity means recruitment criteria need relaxed
obtaining and maintaining informed consent is complex  even
more so over time if disability is degenerative (e.g., dementia)
expert liaisons can cause problems in own right  mismatched
expectations, “lost in translation”, lack of motivation (no direct
benefit to them)
experimental/evaluation control may need to be relaxed
heightened consequence of device failure during evaluation with
disabled populations
guidelines for inclusive PD of AT…
work with existing support organisations
finding & recruiting, variety of domain experts with motivation,
appropriate & ethical treatment of members, premises for performing
the research (familiar to participants albeit less control for
researchers)
assess users’ and experts’ needs, abilities & expectations
take time to understand personal characteristics and motivations of
individuals to gauge level of participation (can inform design process
as well as design itself) – can help avoid mismatched expectations
choose design/eval technique & analyse its requirements
elicitation (above) is crucial to selection of appropriate “tools” and later
adaptation, appreciate demands techniques place on participants
relative to capabilities, recognise where the flexibility lies in the tool
guidelines for inclusive PD of AT contd.…
sympathetically adapt chosen approach
creatively adapt chosen method to suit participants, learning via
iterative application
accommodate comorbidity issues
when adapting approaches, don’t just compensate for primary
disability, but additionally accommodate comorbidities; may even be
possible to use technology to enable participation
use metaphors & pertinent tangible objects to encourage and
support envisioning of technology
can prove crucial in assisting participants to envisage technology –
especially innovative mobile technology – to visualise their ideas, and
encourage creative thinking
guidelines for inclusive PD of AT contd.…
use non-technical (accessible) language
mediate language according to communication and cognitive
capacities of participants – facilitating effective understanding of
unfamiliar concepts enhances participants’ contribution and increases
mutual learning
establish friendly atmosphere
informal, friendly atmosphere to avoid overwhelming and to relax
participants and stimulate contribution – predicated on development
of trusted, professional relationship
might mean loosening some methodological control/norms –
influencing data collected
evaluation based on case studies likely to be more powerful &
feasible
guidelines for inclusive PD of AT contd.…
clearly communicate nature of participants’ involvement
avoid harm of mismatched expectations, especially when expert is
liaising
attempt and refine approach
after deploying a method, need to monitor effectiveness and revise
based on observed practical use
sensitivity developed and trust engendered in researchers during
early research stages can have significant positive impact later
evaluate technology in different contexts
evaluate technology across contexts in which target users spend lives
intro to case study #1 (SMART)…
22% of world’s population will be 60+ by 2050
healthcare reforms needed
285 million people worldwide with age-related macular
degeneration (AMD) – most common cause of sight loss in UK
progressive, degenerative disease severely affecting macula, vital
for clear central vision
link between diet & disease progression
diet risk factors not easy to monitor in routine clinical appointments
Self-Monitoring, Ability-Reactive Technology
(SMART) for users with AMD to support
dietary-based AMD progression retardation
over time
SMART…
engage with support networks
approached clinical experts for advice on how to engage AMD
users  user participation in research in ophthalmology was not
democratised process we were proposing
immersed ourselves in AMD community support groups – build
trusted professional relationship with prospective participants
highlighted individuals’ reluctance to participate in research due to
misconception that they will be “used” rather than considered experts
in living with their condition
convince in word and action that we considered our participants
experts and wanted to involve them as such  later evidence that we
changed their opinion of research involvement
key to successful recruitment for subsequent stages
SMART…
engage with support networks
afforded opportunity for communication of project, etc.
all paperwork produced in various font sizes
participants encouraged to review with support network before
consenting
SMART…
focus groups
impediment to involvement was travel  small (but ideally sized)
focus groups in local, familiar place (coffee shop)
separate one-to-one interviews with clinicians (avoid “white coat
syndrome”)
formed around existing communities so effective atmosphere for
stimulation and encouragement of group discussion
focus groups launched participatory research  start learning
about our users’ lives, experiences, attitudes, coping strategies,
and then finally opinions on proposed system
helped us determine context and focus for later activities
SMART…
focus groups
enthusiasm for tech was promising  mutual learning would
ultimately be key to endurance and success of project:
“we are in a position where technology can help us”
positive and inclusive reaction to proposed technology:
“It could become by best friend. It would become my companion, give
me an incentive and fill my day. […] I am gobsmacked to what
technology can do and that I can be part of it”
SMART…
in-home observations
differences in experiences of living with AMD  differences in
needs w.r.t. assistive technologies
needed to achieve a true sense of “being there”  experiencing
their daily lives
appreciation of daily coping strategies and tech requirements to
inform design
4 focus group participants for in-home observational studies
observed number of prominent trends/commonalities across all
living arrangements  fed into later method set-up and design
itself
reinforced importance of placing end users in central, inclusive
role – without doing this, unable to relate
SMART…
participatory design
chose PICTIVE PD to empower participation  natural fit with
identified user capabilities and objectives
familiarity of materials allowed everyone to contribute equally
works well with small groups  group was small but representative
suited to adaptation
very relaxed structure
accompanied by informal coffee chat – social benefit
stimulated contribution and enhanced trusting relationship
location mirror in-home environment (brightly lit & quiet)
avoided cross-talk to combat comorbid hearing problems
taxi-based return transport provided (avoid travel barriers) –
reinforced importance of project & significance of contribution
SMART…
participatory design
sessions commenced with summary and quick updates throughout
– accommodate comorbidities
participants dictated session length  regularly double what we
had planned
adaptations included removing need to read/write from participants
(researcher’s job)  central design space + individual copies to
accommodate personal reading angles
heavy reliance on metaphors to explain concepts + devices to
envisage application
participants keen on mutual learning  further engaged participants
SMART…
participatory design
to avoid mismatched expectations, explained to participants: how
design sessions allied to overall project scope; what subsequent
phases would be; and the overall expected outcome from the
current phase
during one session, clinician was invited to join the group where
the AMD participants explained their design choices to her
outcome was specification in paper prototype form
truly reflective process  design team (researcher and
participants) constantly adjusted output as they progressed
participants not given homework between sessions but regularly
phoned up to discuss their personal reflection
SMART…
participatory design
reflected on process with participants
“Interactive projects are exciting! Yes – I have seen first-hand the
benefits of this type of research. I have felt very ‘responsible’ for
the success of this project”
“It was challenging, thought provoking and exciting! I would
happily be involved in future projects of this nature. It has been a
pleasure to be involved”
SMART…
involvement of clinical experts
AMD participants, very positive and altruistic  contrast to
negativity of experts
longer spent communicating goals to AMD individuals than clinical
experts – perhaps accounts for difference in attitudinal response
…maybe more time and care needs to be spent assessing
experts’ needs, opinions, expectations, etc.? – natural but flawed
assumption that they require less effort than the participants with
disabilities
maybe benefit to experts observing participants’ reaction – might
enable more open mindedness and positivity?
intro to case study #2 (ALEX)…
functional illiteracy rates in 16-65 year olds in world’s richest
countries is alarmingly high
adult illiteracy  social disability
profound effect on individual’s capacity to function in society and
on innovative and adaptive capacity of a country
basic adult education marginalised compared to compulsory
schooling
barriers to engagement in community-based literacy education
ALEX – a mobile Adult Literacy support application for
EXperiential learning
ALEX…
engage with support networks
worked with literacy organisations
engaged involvement in terms of recruiting tutors and students
conducted some of the work in their facilities (comfort zone)
introduction within familiar environments put participants at ease and
maximised their involvement
without their involvement, social stigma associated with illiteracy
would have made recruitment very hard
facilitated later evaluation stages as well
ALEX…
engage with support networks
very deliberate in efforts to ensure participants understood what
was asked of them and project goals
all textual information in language appropriate to literacy level
all information presented verbally and students given chance to
ask questions
careful communication to tutors avoided mismatched expectations
ALEX…
focus groups
key focus groups with tutors and students to understand aspects
of the students’ lives, their coping strategies, etc.
no impediment to participation other than self-belief, so ensured right
“power” balance in small groups
tutor group separate to student group to avoid intimidation or
embarrassment
learned so much about their circumstances and coping strategies
that was crucial to process  method and outcome
value of experiential learning
mobile tech  status levelers
clear support for mobile app consensus on functionality, and idea
of constraints
ALEX…
participatory design
tutors (1) & students (4) integrated  reflected existing
relationships  tutors very positive about tech  power balance
PICTIVE PD to empower participation, avoiding lots of written
material
familiarity of materials allowed everyone to contribute equally
PICTIVE was natural fit with identified user capabilities and objectives
works well with small groups
regular reminders that they were part of the design team, experts
on their own needs  continuous validation of input
heavy reliance on images and graphics to communicate concepts
and ideas
ALEX…
participatory design
adaptation en route  e.g., reduced session duration due to short
attention span
reflection of participation at end was positive:
“as a group, we achieved something good that will help a lot of
people”
“[it was a] safe place to talk about issues, [I liked] being listened to,
it was a friendly group, easy going, and learning about others”
“[I liked being able to] help put down things that apply to our lives
into the design”
concluding reflections…
far from older adults being technologically averse (common
misconception)  considerable scope for positive impact of
technology if designed appropriately
participatory UCD need not be costly  certainly less than the cost
of abject failure or fixes post-release!
conducting this kind of work can present number of challenges –
e.g., finding/recruiting participants, engaging participants with
impairments  appropriate engagement of user community and
adaptation of method can overcome challenges and yield
invaluable results
concluding reflections…
application of methods should be reflective and educational
experience for all  value of mutual learning
mutual learning  participants can feel relaxed and able to
contribute without prior knowledge/expertise
appropriately adapted, PICTIVE is really empowering 
evidenced across different “disabilities”
strong bond between participants and researcher  fundamental
source of participant motivation and determination:
“none of us want to let [researcher] down, so when we start this, we
will keep on going, we got to prove it. We are the pioneers”
AMD participants felt that this let them better relate to and feel part
of a much younger, technologically-advanced generation
challenges remaining…
how do we “end” participatory processes?
evidence of positive influence of participation  cognisant of the
potential negative effect that withdrawal of the process may have
mission to consult with participants on how they think the process
can be drawn to a close in as positive a way as possible 
empowering them to further influence the context of the research
trust gained at the beginning has to be handled sensitively at the
end
