Two-handed input in a compound task

摘要: Four techniques for performing a compound drawing/color selection task were studied: unimanual technique, bimanual technique where different hands controlled independent subtasks, and two other in which the action of right hand depended on that left hand. We call this latter class two-handed “asymmetric dependent,” predict because tasks sort most closely conform to everyday world, they would give rise best performance. Results showed one asymmetric bimauual techniques, called Toolglass did indeed overall Reasons superiority are discussed terms their implications design. These contrasted with kinds it is shown how, if designed inappropriately, can be worse than one.
