AB  - We investigate the performance of one-handed touch input on the side o
f a mobile phone. A first experiment examines grip change and subjecti
ve preference when reaching for side targets using different fingers. 
Results show all locations can be reached with at least one finger, bu
t the thumb and index are most preferred and require less grip change 
for positions along the sides. Two following experiments examine taps 
and flicks using the thumb and index finger in a new two-dimensional i
nput space. A side-touch sensor is simulated with a combination of cap
acitive sensing and motion tracking to distinguish touches on the lowe
r, middle, or upper edges. When tapping, index and thumb speeds are si
milar with thumb more accurate and comfortable, and the lower edge is 
most reliable with the middle edge most comfortable. When flicking wit
h the thumb, the upper edge is fast and rated highly.
