Note: The article was written in August 2015, the current VR game demo has been completed, so the last time to share some of the experience of pre-research, I hope to help youBackgroundAt the beginning of contact with Oculus, downloaded from the Internet a lot of demo to experience, but the operation experience is mostly poor, especially FPS class. It also makes us realize that for VR games, the biggest challenge is not the way the display changes, but the way they interact. In an immersive envi

It was used with another left hand, and playing the game was not affected, this time it was good, and the death was directly declared. I gave it a depressing day that day. in front of it, he was bitten by the wire of NOKIA's original charger. Now there is another problem with the tail snake. Tragedy. Another reason for buying RAZER is that when I was in college, I took the mouse to rep

The specific structure of this HDD hard drive is not detailed, we all know HDD hard disk is a mechanical structure, affecting performance of the main motor speed, disk density, head number, cache capacity, and other factors, but not the point.
Improve HDD performance is mainly by improving the speed, the current mainstream is 7200RPM, high level of civil 10000-15000rpm, but high spe
of thin Film keyboard
Thin-Film keyboard is the most commonly used keyboard, it has a long life, moisture, dustproof, oil and other advantages. Although it can cope with the relatively harsh environment, but this does not mean that we do not need to pay attention to the protection of the film keyboard, if not pay attention to maintenance, quality and good film keyboard is not durable.
With the increase in the use of time, the touch of the thin-film keyboard will appear such as astringent, but

As the load current changes and the ambient temperature changes, the power cable will undergo thermal scaling. The great thermal mechanical force is generated due to the thermal expansion and contraction of the wire core. The larger the cable core section, the larger the thermal mechanical force is generated. At the same time, the wire core and metal jacket may also produce creep due to multiple cycles of t
