Abstract
An electronic system generates at a display virtual writing corresponding to tracked motion of the tip of a pointer with respect to a surface based on proximity of the tip of the pointer to the surface and the gaze of a user's eye. The electronic system determines the location and motion of the tip of the pointer with respect to the surface based on images captured by scene cameras, and determines the focus and gaze direction of the user's eye based on images captured by a user-facing camera. By generating virtual writing at the display corresponding to tracked motion of the tip of the pointer based on proximity of the tip of the pointer to the surface and based on the focus and gaze direction of the user's eye, the electronic system can enable virtual writing and associated collaboration services without the need for a specialized writing surface or pointer.
