In general, the results were positive. Users found the color notation clear, and
found it easy to navigate and control the 3-D model used in the PDA application (fig.
17). These results with respect to the developed interface are especially encouraging,
since the majority of the users were wheelchair patients, many of whom wore glasses,
and whose condition was compounded by other disabilities (such as motor ones).
Strongly positive results were obtained with respect to the ability of the prototype
to record pain data anywhere, anytime, and especially, with the fact that it allows the
patient to show clinicians how their pain varies across the day, in this respect, the
trend confirming earlier results of [47]. Furthermore, patients generally disagreed
with statements regarding the difficult of data input and upload (fig. 18).

Some of the comments made by patients when evaluating the application include:
“The application allows me to correlate more closely the pain I am experiencing
with the activities that I had been doing . . .”
The patient then remarked that, as a result of self-monitoring of how activities
impacted his/her pain levels, he/she could manage the pain much better by reducing
those activities that led to intense pain.
