According to Xinhua News Agency, San Francisco, April 5 (Reporter Ma Dan) If many head-equipment listings make 2016 a virtual reality "first year," these devices are ready to abandon external devices such as handles and sensors in 2017. "Outside" tracking technology gives consumers a more natural and fluid virtual reality experience.
US Silicon Valley company Ling sense technology research and development "inside and out" tracking technology solutions to attract a lot of attention in the industry. Ling Sen has launched the 3D gesture interaction module Fingo, claiming to be the first company to implement 26 degrees of freedom gesture tracking on the mobile side.
"From the inside out" tracking means that the head mounted device has a built-in tracking system that allows users to track gestures, displacements, and environments without the use of external devices such as handles, resulting in a more natural human-computer interaction experience and greater immersion. Sense of virtual reality experience. In contrast, many existing virtual reality headsets use "outside-in" tracking, which requires external cameras and sensors in the surrounding space to track user actions.
Put on Google's VR helmet “daydream†with Ling’s Fingero module, swinging his hands, and seeing gesture changes appear in real time in the virtual environment. Through the small application for demonstration, you can further experience the interaction of your own hands with the virtual space, such as grabbing a cup, tapping a basketball, ringing a chime, and holding a pen.
Ling-sen engineers explained that Fingo has built-in two infrared cameras to input the images into the mobile phone. The computer vision algorithm can recognize the position and rotation of the 22 joints of the hands and track the gesture of 26 degrees of freedom. In addition, it can also track the rotation and displacement of the head by 6 degrees of freedom.
There are also many large U.S. technology companies chasing "inside out." For example, Intel's integrated virtual reality solution Alloy project, O'Culus's all-in-one virtual reality helmet Santa Cruz, and HTC's recently launched Vive tracker all incorporate "inside and out" tracking technology.
Like the entire virtual reality industry, the "inside-out" tracking technology is still in its early stages and is still immature. But Ricardo Steibel, senior vice president of HTC’s VR business, said that this kind of technology has unique advantages. In the next few years, it will see “inside and out†tracking technology evolve and become a solution.
