OLED Microdisplay Based Eyetracking HMD

Fraunhofer IPMS is first off the blocks yet again with their latest thingamajic,the first OLED microdisplay-based eyetracking Head Mounted Device (HMD) in the world over at SID 2011 and the rig is much like a monocle, except with a transparent OLED display inside, which overlays digital information on top of the reflected light that usually hits your eyeballs………….

 

Fraunhofer IPMS, Dresden carries out customer specific developments in fields of microelectronic and micro systems technology serving as a business partner that supports the transition of innovative ideas into new products. Fraunhofer IPMS develops and fabricates modern MEMS and OLED devices in its own clean room facilities. In addition to R&D services it offers ramp-up within a pilot production. With modern equipment and about 200 scientists and engineers, the range of projects and expertise covers sensor and actuator systems, microscanner, spatial light modulators, wireless microsystems as well as organic materials and systems.The Fraunhofer IPMS works on the integration of sensors and microdisplays on CMOS backplane for several years now. For example the researchers have developed a bidirectional microdisplay, which could be used in Head-Mounted Displays (HMD) for gaze triggered augmented-reality (AR) aplications.

 

The chips contain both an active OLED matrix and therein integrated photodetectors. The combination of both matrixes in one chip is an essential possibility for system integrators to design smaller, lightweight and portable systems with both functionalities.Rigo Herold, PhD student at Fraunhofer IPMS and participant of the development team, declares: “This unique device enables the design of a new generation of small AR-HMDs with advanced functionality.”The OLED microdisplay based Eyetracking HMD enables the user on the one hand to overlay the view of the real world with virtual contents, for example to watch videos at jog.Rigo Herold will present the system at the exhibitor forum at May 17, 2011 4:00 p.m. And on the other hand the user can select the next video triggered only by his gaze without using his hands.On the SID 2011 a demonstrator will be presented for the first time, that has the following technical specifications:

  • Monochrome
  • Special Eyetracking-Algorithm for HMDs based on bidirectional microdisplays
  • Front brightness: > 1500 cd/m²
