Old approach: “fit the user into the system”

“Here is your
map

….

You live
here



Your destination is
here



Your bus will have this
label


When you see this
landmark
,
remember to
pull the cable

on
the bus so the driver knows you
will get off at the next stop.

This is where you will
get off


Don’t forget your
backpack
!

OK, now let’s talk about the
schedule

…. do you know how to
read a
clock
? … “

New approach: design a system to “fit the user


other things I can do

things I have to
remember

“Constructive” solution for mobile users

Proof
-
of
-
concept

of a location
-
aware, mobile
device that:



gives personalized, logical choices

(based on location, time of day and week, abilities,
etc.)



provides multi
-
modal information and
feedback
in response to user choices and
actions.



communicates with a “virtual”
transportation system

(and potentially other
sources of information) to:


locate the “right bus”


prepare for boarding


get on the “right bus”


prepare to get off at the “right” location


reward good performance


provide “cognitive post
-
its” to remember items
easily forgotten in a complex itinerary

Virtual 3D/real
-
time display

For caregivers:


Supports preparation and training:


to better visualize/understand/interact with a complex and dynamic
system


to design see how personalized user prompts (prompting content &
sequence, preparation time, prompting frequency, etc.) will interact with
real
-
time vehicles.

Support real
-
time monitoring and assessment:


use a 3D real
-
time display to make “confederate observations” of
MULTIPLE users


determine real
-
time errors, and offer contextualized, real
-
time help


review performance errors, and create training/intervention strategies

Research hypotheses


independence:

mobile architecture will afford an ability to
learn more routes, leading to increased independence.


learning:

instantiates an “errorless learning” strategy;
supports learning and using “individually relevant” routes.


efficiencies:

less time to learn a route; more time to learn
different routes; allows overworked therapists to identify and
focus on users with greatest needs.


personalization:

memory and attention prompts can be
contextualized and dynamically tailored to suit user needs.


safety:

dynamic error detection and recovery strategies can
incorporate both automated and human intervention.


assessment
:

can collect real
-
time data for development,
user training and personalization, while avoiding abandonment.


scale:

can be used in other transportation systems with bus
GPS infrastructure technologies (see nextbus.com).

many potential “space program” applications!

future work


architecture integration
(goal: seamless “look and
feel” for user communities)


error detection and recovery
(“panic button”)


caregiver feedback

(identify training and technology
needs, script creation and modification)


personalization technologies
(customizable by
caregivers; adaptable to users; engaging to use; supportive of
learning and growth)


test and evaluation on a mobile, wireless
platform
