All leading manufacturers of VR headsets agree that the track view will be fundamental for the next generation of virtual reality equipment, because the ability to control eye position in real time allows the computer to optimize rendering of details and even offer controls without the need for movement of the arms or head. But the equipment for the tracking of opinion at present is neither cheap nor small, so researchers at Nvidia came up with a new solution, which could allow the technology to become more common.

 

New tracker sight Nvidia uses standard LEDs — their ability to emit and perceive light to simplify the process of determining the position of the eye relative to the display. Like other tracking systems view, the system Nvidia uses a ring of infrared LEDs to project invisible light into the eye, but here LEDs are used for the sensitive color perception of the same place. The researchers note that this provides the smallest and cheapest of the solutions track the eyes, while matching the accuracy and the sampling frequency of today’s most popular solutions.

 

In one prototype Nvidia uses a total of nine LEDs on the eyes, three of which emit the IR light, and six perceive light, and the second prototype uses six LEDs on the eyes as light sensors and light sources. Because LEDs consume little energy and use relatively simple hardware and software controller, they reduce latency, reduce the number of cameras required for the headset, and eliminates the need for additional image processing unit in the pipeline the headset.

 

While Nvidia effectively enough to work with a typical VR applications, researchers warn that it may not be suitable for reading, application of neurological or psychological research. While the led system has “good” average angular error of 0.7 degrees and the average angular error of 1.1 degrees, the alternatives on the basis of camera can produce results “very high precision” levels with errors less than 0.5 degrees. Nvidia also notes that the initial phase of calibration “relatively long” compared to other solutions, which in many cases use the system “see here, here, here and here” to sync with the eyes, and should repeat the calibration if the user’s face moves relative to the sensory equipment.

 

Led system Nvidia-sensitive view, is still at the stage of prototype, so it is still not ready to challenge the decisions of the Tobii used in headsets HTC Pico VR or alternative 7invensun selected for Nreal Light. But it can permeate into the new generation of VR headsets, creating a new class of inexpensive and light models with better performance, provided that the researchers will find ways to make the calibration process fast enough not to annoy users.
