Abstract
Methods, systems, apparatus and devices for the lens design of an HMPD with eye-tracking capabilities. The integration uses a low-level optical configuration in order to achieve a compact, comfortable, easy-to-use system. The optical system is further designed and optimized for sharing of the optical path between the HMD and the Eye-Tracker with minimal performance loss for both tasks.
