4.3 Experiments
We are currently preparing to conduct experiments
to evaluate the advantage 1 s of Rebo. Impression on the
appearance, usability, ease of finding functions, and eye
movements will be compared between Rebo and a
typical TV Infrared remote (lR remote). Eye
movements measured by an eye-tracking system (Tobii
T60) will be used to investigate the manipulation
without looking at Rebo. Fig. 7 shows a snapshoot of an
experimental environment. Through these experiments,
we will evaluate Rebo's advantages: familiarity,
function awareness, and stroke manipulation.
