7.3.2 The MAPS-Prompter (MAPS-PR)
MAPS-PR presents to clients the multimedia scripts that support the task to be
accomplished. Its function is to display the prompt and its accompanying verbal
instruction. MAPS-PR has a few simple controls (see Figure 7.4): (1) the touch
screen advances the script forward one prompt, and (2) the four hardware buttons
on the bottom are mapped to (i) back up
.
one prompt, (ii) replay the verbal prompt,
(iii) advance one prompt, and (iv) activate panic/help status. he mapping of the
buttons to functions is configurable to account for the needs of individual users
and tasks.
he current platform for the MAPS-PR is an IPAQ 3850. he system
was implemented for any machine that runs the WIN-CE operating system.
MAPS-PR has cell phone and GPRS functionality. he prompter software was
originally written in embedded Visual Basic, and then ported to the faster and
more lexible C# .net environment. he prompter software supports single-task
or multitask support.
he lack of support for co-evolution causes much of the
abandonment
[21] of
assistive technology tools. Caregivers, who have the most intimate knowledge of
the client, need to become the “programmer/end-user developer” of the application
for that person by creating the needed scripts.
Frey [28] uses a schema to analyze sociotechnical systems that divides the sys-
tem into seven components. hese parts: hardware, software, physical surround-
ings, people (groups or roles), procedures, laws, and data (and data structures), give
