1 MAPS ‘n’ Me (Memory Aiding Prompting System) Stefan Carmien 3.30.05 L 3 D presentation

2 Overview Part 1- Rehearsal of CHI presentation Part 2 - Recent work Part 3 - Left to do

3 Stefan Carmien Center for LifeLong Learning and Design CHI 05 April 2005 End User Programming and Context Responsiveness in Handheld Prompting Systems for Persons with Cognitive Disabilities and Caregivers

4 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

5 Related Research Traditional prompting support Distributed Cognition Scaffolding & Situated Action Existing Computer Based Prompting Tools

6 Why other applications did not thrive Universe of One Reconfiguration Issues Change & Safety

7 Unique Requirements Metadesign Low entry threshold Dual user interface Need to allow tailoring of script annotation for errors

8 MAPS design Script editor target user Design by composition & modification; Error trapping / script annotation

9 Handheld Prompter

10 Script Editor

11 System Evaluation Proof of concept testing with glider script – why did it succeed Script editor testing –Protocol –iterative design / changes

12 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.

13 PLANS FOR FURTHER STUDY realistic environments with dyads testing assumptions about error trapping and extracting real errors

14 Thanks This work is supported by: –Coleman Institute for Cognitive Disabilities –The RERC on Advancing Cognitive Technologies funded by the National Institute on Disability and Rehabilitation Research (NIDRR), U.S. Department of Education under Grant #H133E040019. –National Science Foundation SGER: Designing and developing mobile computing infrastructures and architectures to support people with cognitive disabilities and caregivers in authentic everyday tasks”, National Science Foundation Special Grant for Exploratory Research (#IIS-0456043) –Imagine!

15 Part 2 Recent work –Script Annotation extensions to caregivers script editor –Image experiment –Papers & Presentations

16 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

17 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

18 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”)

19 Demo here

20 Image recognition study MAPS uses prompting for task support Prompts are made up of images and verbal insturctions Images - but what kind?

21

22 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

23 Papers Pac Rim CHI HCII (the eternal tools paper)

24 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…..

25 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

26 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

27

28 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

29 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

30 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

31 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

32 That’s All! Oh yes, and write the dissertation……………

33 Thank You
