Abstract:
This paper reports on the investigation of the differential levels of
effectiveness of various interaction techniques on a simple rotation and
translation task on the virtual workbench. Manipulation time and number
of collisions were measured for subjects using four device sets (unimanual
glove, bimanual glove, unimanual stick, and bimanual stick). Participants
were also asked to subjectively judge each device's effectiveness.
Performance results indicated a main effect for device (better performance
for users of the stick(s)), but not for number of hands. Subjective
results supported these findings, as users expressed a preference for the
stick(s).
