VR indoor positioning technology can locate VR headset and handle VR devices such as VIVE Tracker in space. With space-based VR device can not only provide better immersion, the resulting sense of dizziness will be significantly reduced, the entire screen can be a reality, the world is really moving according to our movements. Indoor location technology is very important for VR desktop virtual reality devices.

HTC vive “Lighthouse” is a laser positioning technology, Oculus Rift and Sony PlayStation VR are optical positioning technology. Oculus Rift is the infrared active optical technology and Sony PlayStation VR is the visible light active optical technology.

HTC Vive’s Lighthouse indoor positioning technology.

HTC’s Lighthouse indoor positioning technology is a laser scanning positioning technology, by laser and photosensitive sensors to determine the location of moving objects. Two laser emitters are positioned diagonally to form a rectangular area of adjustable size. The laser beam is emitted by two rows of fixed LED lights inside the transmitter, six times per second. Each laser emitter has two scanning modules, which respectively transmit laser scanning and positioning space to the positioning space in turn in horizontal and vertical directions.

HTC Vive Heads and handles have more than 70 light sensors. By calculating the time to receive the laser to calculate the exact position of the sensor relative to the laser emitter, the position and direction of the visible head can be detected by multiple photosensors. Need to explain here, HTC Vive laser positioning technology used in the positioning process of the photosensitive sensor ID with the data it receives at the same time passed to the computing unit, which means that the computing unit can directly distinguish between different photosensitive sensors, thus A three-dimensional model of the head and handle is finally constructed, based on the position of each light sensor fixed on the head and the handle as well as other information.
