Background: Mobile Communication
• Remote communication through mobile devices (such as
mobile phones) are changing the way we communicate,
plan, and socially interact
• Mobile communication has the potential to increase safety,
independence, and social connectedness
However:
• At the UI level: Off-the-shelf mobile phones are not
designed with users with cognitive impairments in mind
• At the socio-technical level: The way people with cognitive
disabilities communicate remotely with caregivers is not
well understood

Research Problem
How can we design a remote communication
system with and for individuals with
cognitive disabilities and their caregivers, in the
context of supporting safety, social connectedness,
and increased independence?

Conceptual Framework:
Participatory and Meta-Design
• Software development is a co-creative process between
technologists and end users
• Designers can’t predict how the system will be used, and
so end users must be empowered to act as designers
during use time
• Socio-technical systems will and should evolve over time

Methodology
Phase 1: Formative interview study
•
Interview study with 20 local parents and teachers of children and
young adults with cognitive disabilities exploring AT usage, the
technology adoption process, differences between school and home
Phase 2: Focused interviews, observations
•
Exploring remote communication between parent caregivers and
clients; its role in safety, social connect, and independence
Phase 3: Technology design-through use field study
•
Iterative design process with families as co-creators of a PDA based
assistive communication system that evolves through use

Phase 3: Technology Field Study
Participants
•
4 families from Phase 2
Designing Technological Probe
•
Used by client, supports simple remote communication
•
Initial functionality based on tasks identified in Phase 2
•
Collects extensive usage data
Continuing Diary Study & Naturalistic Observations
•
Parents record usage of probe, problems, ideas
•
I observe clients in activities away from home when remote
communication system may be used
Probe Supporting Design-through-Use
•
Participatory design session every four weeks, probe evolves uniquely
for each family

Data Collection During Use
•
•
Textual log files maintained during use, including:
Power Log:
– When device is turned on and off
– Battery level
•
Call Log:
– When a call is initiated and received (voice will probably not
be recorded)
– Length of call
– Sender/recipient of call
•
Detailed Usage Log:
– Log of users’ sequence of actions
– When system gets into an error state
•
Logs are easily downloaded from PDA onto PC

Types of Customizations during Field Study
Customizations include:
• User interface modifications
• Functionality changes
System should support:
• Creating customizations
• Sharing customizations across users
• Backing-up customizations for easy system restore,
upgrade

Expected Outcomes and Contributions
Design
•
The interviews and design-in-use field-study will inform user interface
guidelines as well as design methods for building assistive technology on
mobile devices for people with cognitive disabilities
System development
•
This research advances our theoretical and practical understanding of
meta-design by designing, building, and evaluating a system architecture
to support the meta-design principles of end-user system modification at
use time through customization and sharing
Theoretical contributions grounded in empirical research
•
•
The role of mobile communication in independence and safety between
parental caregivers and their children;
The technology adoption process for individuals with cognitive disabilities,
and the role of the caregiver network
