Description

A virtual input device

technical field

The utility model belongs to the field of computer equipment, in particular to a virtual input device.

Background technique

As common input tools, keyboard and mouse play an indispensable role in computer equipment. With the advancement of computers, keyboards and mice have also been greatly improved, and keyboards have changed from independent physical keyboards to virtual soft keyboards for tablet computers and touch phones; mice have also experienced mechanical mice, optical-mechanical mice, and optical mice. Optical mouse.

However, the currently commonly used physical keyboard and mouse all have great limitations. Users must put their hands on the keyboard and mouse for physical contact to operate it, which makes the user's hands limited to the keyboard and mouse. The space where the mouse is located, such an input system is centered on machines such as computers, and the user's spatial position and operation methods are restricted. In the prior art, there are also some virtual input devices based on gloves, but this device has limitations on the size of the palm, and sometimes choosing an inappropriate glove will cause input errors, and the sensitivity of this virtual input device is not enough. high.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model.

For the virtual input device shown in Figure 1, four three-axis accelerometers 1 and two ten-axis sensors 2 of the STEVAL-MKI124V1 type produced by STMicroelectronics are respectively set at the fingernails of the two hands, wherein, Two ten-axis sensors 2 are respectively set at the nail positions of the index fingers of the two hands, wherein ten three-axis accelerometers 1 and ten-axis sensors 2 are fixed on the fingers through a lock ring, and each three-axis accelerometer 1 and ten-axis sensors 2. Transmit the collected position signal to the signal processing module 3 using the RAM core processor at the wrist. After the signal is processed by the signal processing module 3, the signal is sent to the Bluetooth receiver 6 on the upper computer 5 through the wireless Bluetooth transmitter 4 , so that the host computer 5 obtains corresponding detection data. A three-axis accelerometer is set for mode selection, and the signal processing module enters different working modes according to the number of data changes collected by the three-axis accelerometer. When the data collected by the three-axis accelerometer used for the selection of the mode changes for the first time, the signal processing module enters the keyboard input mode; when the data collected by the three-axis accelerometer used for the selection of the mode changes for the second time, the signal processing module The module enters the mouse input mode; when the data collected by the three-axis accelerometer used for mode selection changes for the second time, the signal processing module enters the magic input mode; the mode conversion cycles in turn according to the number of data conversions.
