Review of the development at the mixed reality project - see-through HMDs and MR applications

摘要

We describe four kinds of HMDs and 3D application systems which were developed at MR Project in about four years. The first one is an optical see-through HMD with wider FOV(H51° V37°) accomplished by the Free-Form-Surface prism. The second one is a video see-through HMD "COASTAR" designed so that the optical axes of cameras are coincide with the optical axes of display systems of the HMD. The third one is an optical see-through HMD developed in order to use out of doors. The last one is an optical see-through HMD with video cameras designed so that the optical axes of cameras coincide with the optical axes of display systems and the optical axes of optical see-through systems.
