Bi‐directional OLED microdisplay for interactive see‐through HMDs: Study toward integration of eye‐tracking and informational facilities
2009
— First prototypes of bi-directional OLED microdisplay devices that combine both display and camera functionality on a single CMOS chip (OLED-on-CMOS) have been designed. The major goal of this integration is to provide capabilities for eye-tracking in see-through HMDs to achieve gaze-based human-display interaction, e.g., in augmented-reality applications. The development of the prototype was accompanied by user studies with a simulated bi-directional microdisplay consisting of a commercially available eye-tracker and a see-through HMD. These tests were aimed at providing basic minimum requirements in terms of temporal and spatial resolution of an eye-tracker to be implemented within the prototype, as well as to evaluate ergonomics of an appropriate user-interface design. A description of the current state of the hardware architecture and design aspects for bi-directional OLED microdisplays are also presented.
