Problems solved by technology

Among them, input methods such as keyboards and handwriting pads require specific input devices (such as keyboards, handwriting pads, etc.) to realize text input, and are highly dependent on input devices.
Although the touch screen input method does not require specific input devices, it is obviously not suitable for electronic products such as TVs and computers that do not have a touch screen.

[0055] In a first embodiment, the method includes the following steps:

[0056] Step S01, when a command to start writing is detected, a gesture image is collected, and the position of the fingertip in each frame of the gesture image is acquired;

[0057] When the device detects the start writing command, it responds to the start writing command and starts to capture gesture images. For example, when the device detects the start writing command, it provides a floating input box for the user to align the floating input box for gesture input, and at the same time, the device starts the acquisition device (such as a camera, camera, etc.), the acquisition device continuously captures gesture images and saves the gesture images at the same time, wherein the gesture images can be a segment of video, or multiple consecutive pictures.

[0058]Establish a two-dimensional coordinate system (hereinafter referred to as the coordinate system), for example, establish a two-dimensional coord...

Abstract

The invention discloses a mid-air gesture input method and device. The method comprises the steps that when a command of starting writing is detected, gesture images are collected, and the positions of fingertips in each gesture image are obtained; a writing track is generated according to the obtained positions of the fingertips in the gesture images; when a command of stopping writing is detected, character recognition is conducted on the generated writing track, and a character corresponding to the writing track is obtained. According to the mid-air gesture input method and device, the gesture images of a user are collected to generate the writing track, and then character recognition is conducted on the writing track, so that character input can be achieved by the user only by means of mid-air gestures, the input mode is simple and easy to carry out, and the mid-air gesture input method and device are suitable for most of electronic products including televisions.

Description

technical field [0001] The invention relates to the technical field of computer application and pattern recognition, in particular to an air gesture input method and device. Background technique [0002] Currently widely used text input methods include: keyboard, touch screen, tablet, etc. Among them, the input methods such as keyboard and handwriting board need specific input devices (such as keyboards, handwriting boards, etc.) to realize text input, and are highly dependent on input devices. Although the input method of the touch screen does not need to rely on a specific input device, for electronic products such as TVs and computers that do not have a touch screen, the input method of the touch screen is obviously not suitable. Therefore, it is very necessary to provide an input method that is convenient, simple and suitable for use by more electronic devices. [0003] The above content is only used to assist in understanding the technical solution of the present inve...
