Abstract
Application of Head-Mounted Display (HMD) to wearable devices such as military helmets and smart glasses brings us a further step to smart life. However, most of existing smart glasses are equipped with projecting light bars in front of glasses. When people see projected images through splitting prism of the light bar, they may feel the appearance and balance of weights affected. In addition, most light bars are placed at the corner of field of view, enforcing users to rotate their eyes to the corner to read messages or images. This design is neither natural nor fits human visual behavior. The research is aimed at resolving the problem by using optical simulators to simulate different combiner of HMD to narrow the volume of HMD. We hope to make HMD see-through like general glasses or windshield and reduce demand for traditional light bars. In addition, the image can be displayed next to or in the middle of the field of view depending on users’ needs. The enhancement of application scope and convenience can better satisfy customers’ anticipation.
