Or from the basic characteristics of VR: VR's three characteristics - immersion, interactivity, imagination, of which the important technology that affects immersion and interactivity is VR's input technology, today we will talk about VR input technology .
VR input devices such as motion capture, gesture recognition, sound perception and other somatosensory devices (mainly used to input consumer action data, achieve an interactive experience or for content production), interact with the virtual world by perceiving user input information, input devices It is an important technology to realize consumer interaction and immersion.
The input devices of these peripheral classes have high technical requirements, and only the actions can be input and can interact in the content, which is a true VR. The early film production industry has already applied motion capture.
Traditional input devices include a mouse, a keyboard, and the like. In two-dimensional screen interactions, almost all control commands can be abstracted into buttons and swipe actions. For the VR input device, it is more important to realize the natural interaction, and more realistically embody the human motion into the three-dimensional content space, thereby achieving higher immersion, higher efficiency, and lower learning cost.
According to human natural interaction, VR input technology mainly has two major categories: motion input and sound input. From the current development of the industry as a whole, the main reason is the motion input, the sound is currently more in the output equipment (such as panoramic sound headphones, audio, etc.), here we mainly discuss the VR motion input technology.
The current input devices mainly include the following two types: the dynamic capture device and the dynamic control device, as shown in the following diagram:
One is an action control device, that is, a conventional keyboard, steering wheel, and joystick type device. The motion control device is relatively simple and more functional. It mainly relies on motion tracking and button control to interact. This type of equipment is mainly produced by some foreign game companies and used in conjunction with its games. Representative products include Stem, Hydra, Wii, steering wheel, somatosensory guns, etc.
VR steering wheel: mainly used in racing games, control the car in the game through input devices such as steering wheel, brakes and throttle.
VR Somatosensory Gun: The function is similar to the VR steering wheel, mainly used in the game field.
Cut out fuse is a combination of a fuse and a switch, it`s voltage is up to 11kv-33kv, which is made of porcelain, polymer or steel. When the current exceed the specified value, drop out fuse ( polymer cut out fuse and Porcelain Cut Out Fuse ) will produce heat and disconnect. Arrester is made of porcelain or polymer. The voltage is 11kv-33kv. it is a device used on electrical power systems to protect the insulation and conductors of the system from the damaging effects of lightning.
In electrical distribution, a fuse cutout or cut-out fuse is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. we make available these fuses in varied specifications to meet the clients' different preferences in an efficient manner.
