Abstract— 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.
