CID: An Optically Tracked Configurable Interaction Device
A.J. vanRhijn, Jurriaan D. Mulder · 2006
We present CID: a new, configurable, interaction device that enables a user to manipulate a large number of application parameters, using a single, compact device. An interface designer is able to create new configurations of CID by selecting a base object and attaching actuators to it. Actuators provide a combination of translational and rotational degrees of freedom, and define interaction relative to the position and orientation of the base object. The device allows an interface designer to rapidly prototype and evaluate new interaction techniques for complex tasks. Furthermore, the device can be configured specifically for a certain interaction task, such that its structure reflects the spatial parameters of the task. In this case, the perceptual space and control space overlap, contributing to an intuitive interface. CID is tracked using a model-based optical tracking system. A tracker model of a device configuration is obtained by a training procedure. The system automatically estimates the skeleton structure of the configuration, describing how actuators and base object are interconnected, and determines the DOFs and DOF ranges of each actuator. We applied CID in three different application scenarios, showing the flexibility and power of the concept.
