GestAction3D: A Platform For Studying Displacements And Deformations Of 3D Objects Using Hands

We present a low-cost hand-based device coupled with a 3D motion recovery engine and 3D visualization. This platform aims at studying ergonomic 3D interactions in order to manipulate and deform 3D models by interacting with hands on 3D meshes. Deformations are done using different modes of interaction that we will detail in the paper. Finger extremities are attached to vertices, edges or facets. Switching from one mode to another or changing the point of view is done using gestures. The determination of the more adequate gestures is part of the work. 1 Motivations In the early 80's, mice and graphic screens led to a revolution in computer interfaces and quickly became the by far most common 2D devices. Today, a growing number of 3D displays appears on the market: active or passive 3D glasses, 3D Head Mounted Displays and now 3D LCD monitors. However, 3D devices such as pointers, 3D mice and gloves are not widely used, due to the high cost, a lack of applications and most important...
