The caregiver in the second trial was elderly
(70 years old) and had previously never used a
computer. The researcher was required to
guide the caregiver through the CSD due to
her reluctance to operate the computer’s
mouse. The caregiver commented that she possessed
previous experience with touch-screen
technology through working as a cash register
operator. When informed that the CSD could
be presented via a touch-screen interface, the
caregiver stated that this might lead to making
the technology more appealing to elderly caregivers.
Following these comments, a prototype
of the CSD was ported to a 9-inch touch-screen
device. The interface design of the current CSD
lends itself well to a touch-screen interface due
to the large buttons on each screen and the
stepwise wizard.
