Handwriting character input method based on body-sensing technology

Abstract

Disclosed is a handwritten text input method based on a motion-sensing technology, comprising the following steps: configuring a character database comprising the tracks of different characters; configuring a motion-sensing device, and defining a virtual paper within a sensing space; identifying an input state of an operator; the operator lowering a pen to perform handwriting; the motion-sensing device determining, on the basis of a pause by the operator, that the input of a single character has ended; when the handwriting of a character is completed, sensing a track drawn on the virtual paper; a computer performing a feature matching between the track and the tracks in the character database; listing matching candidate characters; and the operator making a selection. The present invention obviates the reliance on fixed input devices such as conventional keyboards, microphones, and writing tablets, also obviates the need for any sensing instrument, allows for handwriting to be completed within the sensing space of the motion-sensing device, provides freedom for writing and comfortable operation, allows for increased text input speed, and allows the operator to configure, on the basis of input habits of self, the thickness of the virtual paper and the distances for pen-lowering and pen-lifting, thus achieving optimal input experience.

Description

technical field [0001] The invention relates to a handwritten character input method based on somatosensory technology. Background technique [0002] With the development and maturity of somatosensory technology, the application of somatosensory technology to the field of computer input has been realized, providing humans with a more comfortable and natural computer input method. Microsoft's Kinect and Leap Motion's Leap 3D are currently two mainstream brands in the field of somatosensory input. On the premise that the operator does not need to hold any sensing props, the operator's movements are captured and recognized through cameras and sensors. However, the current somatosensory technology is mainly used in the game field, which can sense and recognize the actual action of the player to control the corresponding action of the character in the game, which can bring better game experience to the player. However, space-based somatosensory technology has not been applied to...

Problems solved by technology

However, space-based somatosensory technology has not been applied to the field of text input. Existing computer text input usually uses keyboard input, voice input or tablet input, which needs to rely on a fixed input device, which is not very free to use. Not ideal for comfort
