The purpose of this research is to investigate the effects of age and sex o
n remote pointing movements. In addition, an attempt was made to incorporat
e possible age-related or sex differences into the design of a remote point
ing user interface. The subjects were recruited from three age groups (elde
rly, middle-aged, and young) with equal number of both sexes. The participa
nts were required to perform cursor positioning tasks using a remote pointi
ng device. Their static hand stability and remote positioning time were rec
orded and analyzed. The remote positioning time was further separated into
two components: initial submovement duration and adjustment submovement dur
ation. The results reveal that age-related effects reduced the subjects' ab
ility to perform remote pointing tasks and also maintained hand stability.
However, sex differences had no significant effect on either performance. M
oreover, the results also reveal that remote positioning movements for the
young group were mostly completed in their initial submovement phase, while
the elderly subjects spent most of their movement time on the fine adjustm
ent phase. In light of the fact that different age groups exhibit different
kinds of movement behavior patterns, suggestions for the design of signal
sensitivity, target features, and display/control gain in remote pointing u
ser interface were outlined.
