Popis: | For the goal of designing a wearable low vision aid, aspects of both head-mounted display (HMD) design and performance evaluation were integrated into a single study of scanning ability. A head-mounted version of a novel retinal light scanning display known as the virtual retinal display was fabricated for this study. A remote head CCD (charge coupled device) attached approximately at the user's line of sight was used as the input source. Scanning ability was quantified as the time to identify a target in a wide field of distractors while using the HMD design in four different display interface modes (DIMs). Each DIM was tested with respect to their corresponding controls: A (augmented, see-through) and CO (center occluded) DIMs were compared to the augmented control (augmented, retinal display turned off), and CPO (center and periphery occluded) and PO (periphery occluded) DIMs were compared to the periphery occluded control (periphery obstructed, retinal display turned off). Each DIM was tested at high,... |
