Abstract
A head-mounted display (HMD) device includes a plurality of deformation sensors attached to a liner formed around a periphery of a HMD, adopted for direct or indirect contact a user's face. The deformation sensors measure deformations of the liner caused by movement of an upper portion of a user's face when the user is wearing the HMD. The deformation sensors are strain gauges embedded in or otherwise coupled to the liner of the HMD. The sensors translate muscle movements of the upper face of the user to changes in the bending strain and radius of curvature on the surface of the strain gauges. The HMD includes a module that reconstructs and projects a facial animation model of the user based on signals from the deformation sensors while the HMD is in use by the user.
