Problems solved by technology

The traditional percussion-type physical keyboard does play an important role when working in a fixed place. It is easy to operate and is also the first choice of most people. However, if you often go out to work or study, the keyboard will become larger due to its large size It is not easy to carry; the subsequent tablet computer has chosen to add a corresponding touch-screen virtual keyboard to the screen, which replaces the percussion-type physical keyboard and greatly improves mobile portability, but the keyboard needs to occupy the screen. Most of the area will affect the efficiency of office work. If the screen itself is relatively small, the touch-screen virtual keyboard will be small, which will also affect the efficiency of typing.
[0003] The Chinese invention patent with the patent application number CN201611038392.6 discloses a smart wearable keyboard device and its input method, which senses the bending angle and motion state of the finger through the worn sensor, and then converts it into input character information; the wearable keyboard The disadvantages are: more sensors and wearable components need to be installed, not only the volume and weight of the gloves are too large, it is inconvenient to carry, but also the circuit part of the wearable keyboard will be very complicated, and the circuit is easily affected by the surrounding environment, thus reduced its sensitivity
The disadvantage of this wearable keyboard is: each finger needs to be put on a keyboard ring, and the wearing process is cumbersome and time-consuming; and 10 keyboard rings also increase the high production cost and maintenance cost.

Embodiment 1

[0032] Embodiment 1: as Figure 1 to Figure 5As shown, a wearable input device based on optical image capture and processing includes a glove 1, a ring image capturer 2 and a computer 3, the glove includes a glove A and a glove B, and the ring image capturer 2 includes a ring The image capture device A and the annular image capture device B, the glove A and the glove B are a pair; the belly of each finger of the glove 1 except the thumb is longitudinally arranged with three color blocks 101, and the color blocks 101 are Square, the thumb of the glove A is provided with a ring-shaped image capture device A, the thumb of the glove B is provided with a ring-shaped image capture device B, and the ring-shaped image capture device A and the ring-shaped image capture device B both include ring-shaped Belt 6, one end top of described endless belt 6 is arranged with circular catch box 4; In described catch box 4, lay with central processing unit 206, distance sensor 203, flashlight 202...

Embodiment 2

[0036] Embodiment 2: A wearable input method based on optical image capture and processing based on a wearable input device based on optical image capture and processing, comprising the following steps:

[0037] Step S201: the ring image capture device 2 approaches the color block 101, the distance sensor 203 on the ring image capture device 2 detects the distance between the ring image capture device 2 and the color block 101, and transmits the detected distance to the central processing unit in the form of data device 206;

[0038] Step S202: the central processing unit 206 determines whether the data detected by the distance sensor 203 exceeds the set distance threshold, and if so, returns to step S201; if not, the central processing unit 206 sends a control command to the camera and the flashlight 202; the set distance The threshold is 0.5cm.

[0039] Step S203: the camera and the flashlight 202 take pictures and flash at the same time after receiving the control command,...

Abstract

The invention discloses a wearable input device based on optical image capture and processing, which includes gloves, an annular image capturer and a computer. The annular image capturer includes an annular belt, and a capture box is arranged on one end of the annular belt; A central processing unit, a distance sensor, a flashlight, a miniature camera and a wireless transmission module; the ring image capturer is connected with a computer through the wireless transmission module. The present invention also provides a wearable input method based on optical image capture and processing, including: the ring image capturer approaches the color block, and detects the distance between the ring image capturer and the color block; the central processing unit determines whether the detected data exceeds The distance threshold is set; the camera transmits the image to the central processing unit; the image is sent to the computer through the wireless transmission module; the computer receives the image, converts the image into keyboard information and inputs mouse commands to the computer. The invention realizes the input function of the wearable input device.

Description

technical field [0001] The invention relates to the field of intelligent input devices, in particular to a wearable input device and method based on optical image capture and processing. Background technique [0002] At present, with the advancement of society and the improvement of technology, wearable devices have gradually appeared in people's lives, such as smart bracelets, smart glasses and smart headsets. Keyboards and mice are no exception. Common input devices such as mouse keyboards are becoming more and more wearable. The present invention mainly solves the problems of large size and inconvenient portability of traditional keyboards, and overcomes the problems of existing glove keyboards. disadvantages of complex circuits. There are two types of traditional keyboards, one is a percussion-type physical keyboard that is matched with a common computer, and the other is a touch-screen virtual keyboard, such as exists in a tablet computer. The traditional percussion-t...
