Calibration Method of Visual Parameters of See-Through Head-Mounted Display to Adjust Apparent Distance

Abstract

For the purpose of coinciding the virtual environment displayed by See-Through Head-Mounted Display (STHMD) with the actual environment, a new calibration method is proposed. The method is for the calibration of the difference between supposed position and actual position of the user's viewpoint, which is mainly caused by the individual difference of inter-pupil distance. This method is efficient to minimize the error concerning distance. The efficiency is evaluated by sensitivity analysis of visual parameters. It is also confirmed by experiment in which visual parameters of STHMD are calibrated individually, and the calibrated virtual environment matched the actual environment.
