Natural and Fluid 3D Operations with Multiple Input Channels of a Digital Pen

Abstract

We propose six 3D operation patterns with multiple input channels of a digital pen: these patterns allow users to transfer pre-existing knowledge of physical pens to digital pens on performing 3D operations simply, naturally, intuitively, and fluidly. A prototype system was designed under the patterns and implemented. An informal user study showed that eight novices grasped to perform 3D operations with the prototype system within several minutes and gained more fun than with the typical interfaces.
