Embodiment Construction

[0069] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0070] The inventor considers that when a user who can skillfully use a real keyboard to type, his static gesture posture is usually fixed, that is to say, when a certain finger presses a certain key, the relative angle and relative The displacement is fixed within a certain range; and corresponding to the different keys tapped, there are also different static gestures. For example, when pressing "Y" and "U" with the right index finger, the distance between the fingers of the right hand The relative positions are not the same, and when "K" is pressed with the middle f...

Abstract

The invention discloses a method and a device for virtual keyboard input by the aid of hand signs. The method includes capturing gesture information of static hand signs of a user when the user presses different keys; storing the gesture information of the static hand signs of the user when the user presses the different keys and corresponding key information; capturing gesture information of a real-time hand sign of the user when the user inputs information; matching the gesture information of the real-time hand sign with the gesture information of the static hand signs of the user when the user presses the different keys, and acquiring the gesture information, which is matched with the gesture information of the real-time hand sign, of the certain static hand sign; and determining that the key information corresponding to the matched gesture information of the certain static hand sign is the key information inputted by the user. The method and the device have the advantages that only the gesture information of the hand signs needs to be matched, so that the data volume can be reduced, and the real-time response speed is increased; gesture information of respective habitual static hand signs of different users is recorded in advance, so that the method and the device are adaptable to different habits of the users; and as the gesture information of the static hand signs of each user is fixed, the method and the device are high in accuracy.

Description

technical field [0001] The invention relates to the technical field of virtual keyboard input, in particular to a method and device for using gesture virtual keyboard input. Background technique [0002] With the development of technology, the technology of virtual keyboard input using gestures is also constantly improving. Gesture input first requires the collection of gesture information. The currently known technical equipment that can be used to collect gesture information includes: sensors or data gloves worn on the hand for collecting finger angular displacement information, cameras for collecting object image information , laser infrared, etc., which can collect object spatial position information. How to use the above-mentioned technical equipment to collect gesture information and how to analyze it is the key to gesture input technology. Existing technical solutions either simply detect which finger is the finger that the user intends to click and use the thesauru...
