[DEMO] INDICA : Interaction-free display calibration for optical see-through head-mounted displays based on 3D eye localization

A correct spatial registration of Optical See-Through Head-Mounted Displays (OST-HMD) w.r.t. a user´s eye(s) is an essential problem for any AR application using the such HMDs (Fig. 1). Maintaining the correct registration demands frequent (re)calibrations for the end-users whenever they move the HMD on their head. Thus, a calibration technique should be simple and accurate for the universal, long-run use of the displays. This demonstration showcases INDICA, an automatic OST-HMD calibration approach presented in our previous work[1] and ISMAR 2014 paper [2]. The method calibrates the display to the user´s current eyeball position by combining online eye-position tracking with offline parameters. Visitors of our demonstration can try our both manual calibration and our interaction-free calibration on a customized OST-HMD.
