Comparing Single- and Two-Handed 3D Input for a 3D Object Assembly Task

Abstract

In this paper, we describe the design and evaluation of an interface for 3D object assembly that can be operated with either one or two hands. The justification for applying two-handed input is evaluated by studying the results of an experiment in which the performance of single- and two-handed operation are compared. Performance is established using the time needed to complete a 3D object assembly task, Experimental data show that the two-handed interface takes more time to learn but eventually leads to faster completion times within a one hour period. It is therefore concluded that the choice for two-handed input is appropriate.
