End User Programming and
Context Responsiveness in
Handheld Prompting Systems

Disabilities and Caregivers

April 2005
Introduction to MAPS: design
problem
• Designing for persons with cognitive disabilities
• Assistive Technology and support for Activities of
Daily Life (ADL)
• Abandonment Problem
 (Re)configuration
Related Research
• Traditional prompting support
• Distributed Cognition
• Scaffolding & Situated Action
• Existing Computer Based Prompting
Tools
Why other applications did not
thrive
• Universe of One
• Reconfiguration Issues
• Change & Safety
Unique Requirements
• Metadesign
• Low entry threshold
• Dual user interface
• Need to allow tailoring of script annotation for errors
MAPS design
• Script editor target user
• Design by composition & modification;
• Error trapping / script annotation
Handheld Prompter
Script Editor
System Evaluation
• Proof of concept testing with glider
script
– why did it succeed
• Script editor testing
– Protocol
– iterative design / changes
Implications
• Adopting a dual user interface for complex
assistive technology devices → mitigate some of
the causes for device abandonment.
• A dynamic bridge can be made between plans and
events that holds much promise for mobile and
ubiquitous computing applications.
PLANS FOR FURTHER STUDY
• realistic environments with dyads
• testing assumptions about error
trapping and extracting real errors

Part 2
• Recent work
– Script Annotation extensions to
caregivers script editor
– Image experiment
– Papers & Presentations
Script annotation extension
• Iterative design (with Anja)
– Dump the task segment / typical task model
– Start over by making an initial list of all
reasonable:
• Trappable conditions (and tests to capture)
• Corrective actions
• Listing these allowed me to create
structural classes of error tests
Script annotation continued
• These classes of tests were implemented
via a data-driven interface
– allowing addition of new tests without
changing the code of the interface
Script annotation continued
• Further examination lead to division of
these tests into:
– Error trapping/error correction
• i.e. if you left the house without your purse
then….
– Tests as structural elements of the script
• i.e. when your bus is within 30 feet of the bus
stop - display the next prompt (“here is your bus,
get ready to get on”)

Image recognition study
• MAPS uses prompting for task support
• Prompts are made up of images and
verbal insturctions
• Images - but what kind?
Image Experiment
• Finished pilot studies last summer
• Preliminary analysis supports the
proposition that icons are not as
useful (for this population) for
image recognition as photos
Papers
• Pac Rim
• CHI
• HCII (the eternal tools paper)
Part 3

Image experiment
Merging script annotations to lifeline service
Realistic studies
Working with Melissa's data
Oh, and writing a dissertation…..
Image Experiment follow up
• I have now 4 ‘typical’ and 4 young adult
with cognitive disabilities subjects lined
up
• Goal is 15 of each
• Results will be submitted in a paper to
one of the cognitive science/psychology
journals
Merging MAPS annotations into
Lifeline service
• Maps Db structure is ready
• MAPS and Lifeline designers need to
agree on:
– syntax
– Where to ‘slice smartness’
– How to support dynamic script generation (on
the prompter)
• Short Comment on AIMS
Realistic studies
• Projected format is several sets of
pairs of persons with cognitive
disabilities and caregivers
• Drawn from BSVD and Imagine!
Populations
• Use the system for typical tasks for
several weeks
Realistic studies continued
• I will work out the tasks with the pairs
and provide very minimal assistance in:
– Segmenting task
– Image collection & voice recording (actually
quite a bit of assistance for this part)
– Assembling scripts
– Loading script to prompter
– Using scripts to guide task completion
Realistic Studies Concluded
• Shadowing users
• Categorizing errors
• Enumerating possible corrections
• Open question about whether this will be a test that
includes lifeline functionality - possible use of a stub
for wireless i.e.Handheld interface for sensor simulator
to be used in Wizard of OZ studies of MAPS/LifeLine by
URA or DLCRA
Working with Melissa's data
• We have obtained a copy of the HyperResearch
ethnographic tool
• Melissa’s research (interviews of existing use of AT with
caregivers of young adults with cognitive disabilities) last
summer produced 20 3-22 page transcripts
• I am using her transcripts and previous codes to re-code
the data from my perspective and will share the results
• HyperResearch also provides some interesting data mining
and hypothesis testing tools that I will be testing with this
data and the data from my realistic studies
That’s All!
• Oh yes, and write the
dissertation……………
