Abstract
A controller includes a body having a handle, and an array of proximity sensors spatially distributed on, in, beneath, or near the outer surface of the handle, responsive to a proximity of a user's fingers to that outer surface. A finger tracker converts the output of the array of proximity sensors to a set of joint angles corresponding to a plurality of the user's fingers. The controller may include a renderer for processing the joint angles to deform a hand mesh that is rendered for display. Values may be calculated to facilitate normalization of the output of the proximity sensor array and thereby generate a set of normalized finger detection data. This data may be processed through curl logic to produce a linear estimate of gross finger curl with respect to the user and thereby generate a set of estimates for a plurality of finger joint angles for the user.
