An Empiric Evaluation of Confirmation Methods for Optical See-Through Head-Mounted Display Calibration (Poster)
10th IEEE International Symposium on Mixed and Augmented Reality (ISMAR), Basel, Switzerland, Oct. 26-29, 2011, pp. 267-268. (bib)

The calibration of optical see-through head-mounted displays is an important fundament for correct object alignment in augmented reality. Any calibration process for OSTHMDs requires users to align 2D points in screen space with 3D points in the real world and to confirm each alignment. In this poster, we present the results of our empiric evaluation where we compared four confirmation methods: Keyboard, Hand-held, Voice, and Waiting. The Waiting method, designed to reduce head motion during confirmation, showed a significantly higher accuracy than all other methods. Averaging over a time frame for sampling user input before the time of confirmation improved the accuracy of all methods in addition. We conducted a further expert study proving that the results achieved with a video see-through head-mounted display showed valid for optical see-through head-mounted display calibration, too.
