End User Programming and Context Responsiveness in Handheld Prompting Systems for Persons with Cognitive Disabilities and Caregivers
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
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
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
Part 3
• Left to do:– 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
