Interactive Data Glasses

The glasses can read the data in the eyes of the engineers the necessary details to see the building plans. A CMOS chip with an eye tracker in the microdisplay makes it possible. The glasses are connected to a PDA, information display and respond to commands.

For designers of cars, secret agents in movies and fighter pilots, glasses of data - also known as head-mounted or mounted head-up displays for short - are objects of daily use. That carry the user in virtual worlds or provide user data real environment. Currently, these devices can display the information. "We want the glasses and two-way interactive, so that new applications can be opened," said Dr. Michael Scholl, director of business unit at the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden. A group of scientists working on a device incorporating IPMS the eye tracking - users can influence the content presented by moving the eyes or fixing certain points in the image. Without having to use other devices to input instructions, the holder can show the new content, scroll through menus or items makeover.

Scholles believes that a two-way information on the glasses to deliver benefits to all the places where people need to hear more, but not in their hands free to operate a keyboard or mouse. Dresden-based researchers have integrated the system in the eye tracker and image reproduction is a CMOS chip. This makes the HMDS small, lightweight, easy to prepare and inexpensive.

Chip measuring 17 mm 19.3 installed a prototype glasses are dependent on the back of the temple. Temple image of micro-screen is projected onto the retina so that the user appears to be seen from a distance of about one meter. The image is dim ambient light that can be clearly seen against changing backgrounds and very controversial. For this reason, scientists use an OLED, organic light emitting diodes to produce very high brightness microdisplay.

In industry and in medicine, eyeglasses could interactive data to perform many tasks more simply, efficiently and accurately. Many scenarios are possible, including taking vital signs, MRT and X-ray images for the surgeon, construction drawings for engineers to install and setup instructions for service technicians. Some users have already tried conventional HMDS, but the results were not very impressive. In most cases, was considered too expensive, too heavy, too bulky and not very ergonomic. "We have now overcome these obstacles," said Scholes. With his team and colleagues from other Fraunhofer institutes, it is already working on next evolution of glasses bidirectional
