Abstract
Previous research has shown that rotation and orientation of items
plays three major roles during the course of tabletop collaboration:
comprehension, coordination and communication. Based on these roles of
orientation, we designed a novel tabletop rotation mechanism, Rotate N
Translate (RNT), which provides integral control of rotation and translation
using only a single touch-point for input. We present an empirical evaluation
comparing RNT to the standard rotation mechanism that separated control of
rotation and translation. Results of this study indicate RNT is more efficient
than the separate mechanism and better supports the communicative and
comprehensive roles of orientation, without sacrificing support for
coordination.
