Sensor-offset HMD perception and performance

摘要

The perceptual and performance effects of viewing HMD sensor-offset video were investigated in a series of small studies and demonstrations. A sensor-offset simulator was developed with three sensor positions relative to left-eye viewing: inline and forward, temporal and level, and high and centered. Several manual tasks were used to test the effect of sensor offset: card sorting, blind pointing and open-eye pointing. An obstacle course task was also used, followed by a more careful look at avoiding specific obstacles. Once the arm and hand were within the sensor field of view, the user demonstrated the ability to readily move to the target regardless of the sensor offset. A model of sensor offset was developed to account for these results.
