the first two tasks. The third task required the user to
navigate to the ‘sitting’ activity data in the ‘Progress’ tab,
and to count how many days that he/she has reached the
‘sitting goal’. Twenty-five percent completion was awarded
for each of the two correct button presses required, another
25% for counting data from a chart, and another 25% for
correct counting. The fourth task required the user to set
new goals for all three activities. Twenty percent
completion was awarded if the subject navigated to the goal
screen, 50% for entering a goal for each activity and pressing
the ‘Set Goal!’ button, and ten percent for each goal that was
the correct value. In the fifth task, the DPT students and
subjects with stroke were asked to send a message to their
hypothetical patient and caregiver, respectively. For both
groups, twenty-five percent completion was awarded for
navigation to the ‘Goal’ tab, 25% for entering a name, 25%
for entering a sentence and 25% for sending the message.
After finishing the five tasks, the subject completed a survey
inquiring about his or her experience with the interface.
