AI Technical Summary
Existing optical see-through head-mounted displays (OST-HMDs) lack occlusion capability, resulting in virtual objects appearing 'ghost-like' and failing to integrate seamlessly with the real world, and are bulky due to the integration of multiple optical elements, limiting their use in demanding applications.
A compact OCOST-HMD design using freeform optical technology with a shared eyepiece for both virtual and see-through paths, incorporating a spatial light modulator (SLM) for occlusion control, and reflective surfaces to fold the optical paths into two layers, achieving a lightweight and compact form factor.
The design enables realistic integration of virtual objects into the real environment by providing occlusion capability while reducing the device's size and weight, making it suitable for diverse applications.
