Intuitive Interaction
The Two-Handed Interface (THI) lets users do things that are impossible with the mouse, and THI powers every application produced by Digital ArtForms. Driven by a pair of hand-held tracked controllers called SpaceGrips, THI allows users to reach into space to control their viewpoint and to manipulate tools and data. THI can be thought of as 3D multi-touch, but instead of two 2D points on the surface of a flat display, THI gives the user two 6 Degree of Freedom (3 positional and 3 rotational) points in space. Combining these two 6 Degree of Freedom Points together in novel ways enables an intuitive method of interacting with applications, and as a result THI has been shown to perform fundamental 3D tasks at 4-5x the speed of the mouse for novice users (47 minutes of training). This benefit approaches 9x in expert users.
THI has been applied to many applications including Medicine, Design, and Command & Control (Figure 1).
