Caliber VR Spatial Positioning Kit
Another startup company has launched an interactive program for mobile VR. A startup company called Caliber VR announced on August 31 at the media conference in Beijing that the space positioning system for mobile VR was announced.
The hardware part of this system consists of a base station, a handle, and a helmet positioner . The company uses “acoustic optoelectronics†to explain its positioning technology. “Sound†refers to positioning through sounds. The base station emits ultrasound waves that exceed the receiving range of the human ear. The orientation is judged by the handle and the locator on the helmet. “Light†Refers to the laser, the base station emits a laser, and coordinates with the positioning point to calculate the position, which is similar to HTC Vive's Lighthouse, but unlike Vive's helmet and handles, there are only a few points, and a base station; "Electricity" is just a way of data transmission between mobile phones and suites, and it has nothing to do with positioning. Currently, Bluetooth is used for transmission. The company said that it will switch to OTG in the future.

The reason for combining sound and laser positioning is that a single location cannot achieve high accuracy.
This system supports all mobile VR devices as well as Android/iOS phones. Regarding the positioning parameters, the data published by Caliber VR is shown in the figure below.
In the live experience, although the effect of this solution and Samsung Gear VR is not as good as Lighthouse, the task of the game is not difficult to complete. As a construction machine, it should be able to perform better after more adjustments and switching to OTG lines.
The company did not announce the date of the official launch of the product, the price, the developer's plan, and whether there was cooperation, and only revealed the price of several hundred dollars.
Many people think that the enthusiasm for hardware entrepreneurship in the VR field has basically ended, because this one has basically been dominated by big manufacturers, but because the interaction of mobile VR is not yet a particularly good general-purpose solution, many startup companies are still trying various ways recently. Technology and products, the most of which is to imitate the VR head of the PC platform, launched a space positioning system.
Their practices are different, but most of them take into account the lighter platform features of mobile VR, which make lighter spatial positioning than PCs. The so-called lightness is to specify a smaller range of bits, simpler interaction, and lower power consumption. . The recent reports by Lei Fengnet (searching for the “Lei Feng Net†public number) are all the same for uSens, Leap Motion and Hand CV.
19mm key switches
19mm key switches, ie, Key Switch lock, is gradually increase market share with its Diverse functions, accurate operation and Wide range of applications
This 19mm key switches could have 3 position key switch, 4 Position key Switch, which means it could have stronger power to support industrial and other bigger equipment. The exclusive technology of reset functions, multi-position rotation angles are not available in all walks of life,only we can have the technique to realize these.
As for the quality, this 19mm key switches have via UL authentication. In terms of green environmental protection, we adhere to the concept of sustainable development from the procurement of raw materials to the shipment of finished products. Meanwhile, we have professional environmentalist in charging of the whole production system, ROHS environmental protection providing PPAP report for our customers.
At present, our company's power key switches matching detection equipment is roughly as follows:ROHS testing machine, projector, life testing machine, push-pull testing machine, secondary element microscope, power testing machine, salt spray testing machine, etc.
With a sound quality control system and reliable detection equipment, we has created a globally reliable power key switch and has become a trusted producer of electrical key switches.
