Wearable input device and method based on optical image capture and processing

Abstract

The invention discloses a wearable input device based on optical image capture and processing. The device comprises gloves, an annular image capture device and a computer, wherein the annular image capture device comprises an annular band; a capture box is arranged on the upper part of one end of the annular band; a central processing unit, a distance sensor, a micro camera and a wireless transmission module are arranged in the capture box; and the annular image capture device is connected with the computer through the wireless transmission module. The invention also provides a wearable inputmethod based on the optical image capture and processing. The method comprises the following steps that: the annular image capture device approaches to a color lump to detect a distance between the annular image capture device and the color lump; the central processing unit judges whether the detected data exceeds a set distance threshold value or not; the camera transmits the image to the centralprocessing unit; the image is sent to the computer through the wireless transmission module; and the computer receives the image, converts the image into keyboard information and a mouse instructionand inputs the keyboard information and the mouse instruction to the computer. By use of the device and the method, the input function of the wearable input device is realized.

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...

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.
