Digital foam interaction techniques for 3D modeling
Ross Smith, Bruce Hunter Thomas, Wayne Piekarski · 2008
Digital Foam is a new input sensor developed to support clay like sculpting and modeling operations. We present techniques facilitating navigation and manipulation operations performed using Spherical Digital Foam as a sole input device. Our free-form sculpting technique allows manipulation of new and existing 3D models using accumulated sculpting like motions. Digital Foam's multi-point pressure sensitive surface captures the separate locations of a user's fingertips allowing controlled manipulation of multiple model vertices simultaneously. Additionally, we developed a technique that allows the camera view and zoom to be controlled by applying varying pressure to the Digital Foam surface. Furthermore, we have designed a menu system tailored for operation using Spherical Digital Foam as a sole input device using both the internal orientation sensor and the pressure sensitive surface.
