Designing, Implementing and Evaluating Wide-view Optical See-through Head Mounted Displays

Feb 24, 2014

In this talk, I will introduce the design of a wide field-of-view optical see-through head mounted display we have studied as well as a series of user studies on its effectiveness in augmented reality. The development of a wide field-of-view optical see-through head mounted display (HMD) has been a technological challenge for decades. There exist wide-view closed-type HMDs using multiple display units (tiling) or multiple curved mirrors. The former approach tends to be expensive and heavy, whereas the latter approach tends to suffer from image distortion and a small exit pupil. In order to provide a wide-view image with a large exit pupil, I will first introduce design considerations and implementation of our head mounted projective display (HMPD) using a hyperboloidal half-silvered mirror. This, hyperboloidal HMPD or HHMPD successfully provides a wide field-of-view, a large observational pupil, and optical see-through capability. Next I will introduce design considerations and prototyping of a simple head attached screen that is both retro-reflective and semi-transparent. This screen allows the HHMPD to be used in a wearable situation. I will then introduce a series of user studies that assessed different aspects of subjective image quality of the wearable HHMPD, such as visual acuity, perceptual distance and recognizability of information presented in the peripheral vision. I will also introduce user studies on the effectiveness of wide-view see-through HMDs in a simulated outdoor environment using a CAVE-like IPT display that studied relationship between information discovery rates and the field-of-view with a set of different annotation rendering policies. I will also introduce another user study on the effectiveness of the HHMPD that has actually been conducted in outdoor. Finally, I will summarize the talk and give future directions and visions.
