“…As point and click calibration procedures have been shown to be error prone [29], we instead derived a new calibration procedure that utilizes two aspects of the CAVE system: While physically discontinuous, the CAVE environment is meant to be perceptually continuous (i.e. items should not appear different when projected between different screens).…”

“…While Kellner et al were able to improve greatly on the precision of geometric calibration techniques compared to previous work, Tang et al suggested that errors in human performance tend to make these types of methods very error prone [29]. Additionally, Tang et al suggest that calibration procedures for two eyes should be designed to ensure that there is no bias towards either of the eyes.…”

The perception of objects, depth, and distance has been repeatedly shown to be divergent between virtual and physical environments. We hypothesize that many of these discrepancies stem from incorrect geometric viewing parameters, specifically that physical measurements of eye position are insufficiently precise to provide proper viewing parameters. In this paper, we introduce a perceptual calibration procedure derived from geometric models. While most research has used geometric models to predict perceptual errors, we instead use these models inversely to determine perceptually correct viewing parameters. We study the advantages of these new psychophysically determined viewing parameters compared to the commonly used measured viewing parameters in an experiment with 20 subjects. The perceptually calibrated viewing parameters for the subjects generally produced new virtual eye positions that were wider and deeper than standard practices would estimate. Our study shows that perceptually calibrated viewing parameters can significantly improve depth acuity, distance estimation, and the perception of shape.

“…In 2000, Mihran Tuceryan et al [1] proposed typical SPAAM to accomplish calibration by analyzing the mapping from 3D points to 2D points. In 2003, Authur Tang et al [2] compared four calibration methods, suggesting that SPAAM could serve as the first phase of calibration and then use some other method to refine the calibration data. In 2004, Charles B.Owen et al [3] proved the influence from the position of virtual display plane, and put forward a display-relative calibration method which included two phases.…”

The combination of health and entertainment becomes possible due to the development of wearable augmented reality equipment and corresponding application software. In this paper, we implemented a fast calibration extended from SPAAM for an optical see-through head-mounted display (OSTHMD) which was made in our lab. During the calibration, the tracking and recognition techniques upon natural targets were used, and the spatial corresponding points had been set in dispersed and well-distributed positions. We evaluated the precision of this calibration, in which the view angle ranged from 0 degree to 70 degrees. Relying on the results above, we calculated the position of human eyes relative to the world coordinate system and rendered 3D objects in real time with arbitrary complexity on OSTHMD, which accurately matched the real world. Finally, we gave the degree of satisfaction about our device in the combination of entertainment and prevention of cervical vertebra diseases through user feedbacks.

“…VST techniques are difficult or impossible to use for correction in OST displays since the "camera" in these systems is the user's eye itself. Calibrating misalignment between the human eye and augmented geometry, in this case, is not a trivial task [22,26]. Various calibration methods have been developed, which attempt to correct misalignment by employing user feedback, in the form of visual alignments made between on-screen markers and real world locations.…”

With the growing availability of optical see-through (OST) head-mounted displays (HMDs) there is a present need for robust, uncomplicated, and automatic calibration methods suited for non-expert users. This work presents the results of a user study which both objectively and subjectively examines registration accuracy produced by three OST HMD calibration methods: (1) SPAAM, (2) Degraded SPAAM, and (3) Recycled INDICA, a recently developed semi-automatic calibration method. Accuracy metrics used for evaluation include subject provided quality values and error between perceived and absolute registration coordinates. Our results show all three calibration methods produce very accurate registration in the horizontal direction but caused subjects to perceive the distance of virtual objects to be closer than intended. Surprisingly, the semi-automatic calibration method produced more accurate registration vertically and in perceived object distance overall. User assessed quality values were also the highest for Recycled INDICA, particularly when objects were shown at distance. The results of this study confirm that Recycled INDICA is capable of producing equal or superior on-screen registration compared to common OST HMD calibration methods. We also identify a potential hazard in using reprojection error as a quantitative analysis technique to predict registration accuracy. We conclude with discussing the further need for examining INDICA calibration in binocular HMD systems, and the present possibility for creation of a closed-loop continuous calibration method for OST Augmented Reality.
