EyeTracking for bidirectional microdisplays

The IOSB works with state-of-the-art technologies in the field of human-machine interface. Bidirectional displays in eyeglasses allow the pupil and thus the direction of vision to be recorded and information to be displayed to the user at the same time. For this purpose, bidirectional micro-displays are combined with state-of-the-art optics to form compact "See-Through Head-Mounted Displays" (See-Through HMD; Fig. 1), which enable completely new ways of interaction and application design.

The department VID is concerned with the detection of the pupil and the determination of the viewing direction, among other things. In addition, the department develops algorithms specially adapted to bidirectional displays to meet the requirements of these displays.

Another research focus of the VID department is on new interaction technologies, which are only made possible by combining eye-tracking and see-through display in the smallest space.

The second figure shows the interaction concept "World Map" for eye-based interaction with See-Through HMDs. In this application, the user is only shown a section of the world map in the HMD. With the help of his eyes, he can control the position of the section.
