Google glass, The META and Co. How to calibrate optical see-through head mounted displays

Head Mounted Displays such as Google Glass and the META have the potential to spur consumer-oriented Optical See-Through Augmented Reality applications. A correct spatial registration of those displays relative to a user´s eye(s) is an essential problem for any HMD-based AR application. We provide an overview of established and novel approaches for the calibration of those displays including hands on experience in which participants will calibrate such head mounted displays. The following list provides a tentative list of topics covered during the tutorial. • Part 1: Introduction to OST calibration • Why OST Calibration is important? • Differences to Camera Calibration • Introduce camera calibration • Why is OST calibration hard? • The user in the loop — pointing accuracy • Slipping, the need for recalibration • Principal aspects of OST-HMD calibration • overview of data collection • confirmation methods • optimization • mono vs stereo • Details of OST calibration • Data collection methods: • SPAAM, Multi Point collection, stereo methods • Confirmation methods • Optimization approaches • Evaluation: perceptual measures vs. analytic measures • State of the art: Semi-, fully automatic calibration methodses • Part 2: Hands-on calibration • SPAAM-based calibration of Epson Moverio/ Google Glass with inside-out marker tracker.
