A common technology used to present immersive, collaborative environments is the head mounted virtual reality (VR) display. However, due to engineering limitations, variability in manufacturing, and person-to-person differences in eye position, virtual environments are often geometrically inaccurate. Correcting these inaccuracies typically requires complicated or interactive calibration procedures...
We report the results of an empirical evaluation to examine the carryover effects of calibrations to one of three perturbations of visual and proprioceptive feedback: i) Minus condition (−20% gain) in which a visual stylus appeared at 80% of the distance of a physical stylus, ii) Neutral condition (0% gain) in which a visual stylus was co-located with a physical stylus, and iii) Plus condition (+20%...
In this document we present a method for calibrating head-mounted displays and other display surfaces using an automated, low-cost camera system. A unique aspect of this method is that the calibration of geometric distortions, field of view, and chromatic aberration are achieved without the need for a priori knowledge of the display system's intrinsic parameters. This method operates by capturing...
The MEG experiment at PSI searches for the decay μ→eγ at a level of ≈10−13 on the branching ratio BR(μ→eγ/μ→tot), well beyond the present experimental limit (BR≤1.2×10−11) and is sensitive to the predictions of SUSY-GUT theories. To reach this goal the experiment uses one of the most intense continuous surface muon beams available (≈108μ/s) and relies on advanced technology (LXe calorimetry, a gradient-field...
