A method and system for handwriting recognition based on motion sensing

Abstract

The present invention relates to a method for handwriting recognition based on motion sensing and a system for handwriting recognition on a terminal device based on motion sensing. The movement signal is obtained to obtain the first Euler angle group of the first nine-axis sensor and the second Euler angle group of the second nine-axis sensor; according to the first Euler angle group and the second Euler angle group the angle difference, and the relative distance value between the first nine-axis sensor and the second nine-axis sensor, to obtain the first displacement of the first nine-axis sensor, the second displacement of the second nine-axis sensor and the relative displacement of the two, The final recognized handwriting trace. The method and system, by using two nine-axis sensors to detect the relative displacements caused by the respective displacement changes and angle changes, can perform accurate handwriting trajectory recognition without relying on bottom or side sensing devices, and are highly practical and easy to use .

Description

technical field [0001] The present invention relates to the technical field of handwriting recognition, in particular to a method for handwriting recognition based on motion sensing and a system for handwriting recognition on a terminal device based on motion sensing. Background technique [0002] Generally, technology based on motion sensing has been only used in gesture sensing devices due to problems such as precision, and cannot be applied to the field of handwriting recognition that requires high precision. Later, the newly developed technology can realize the detection of written strokes due to the combination of sensors and various handwriting algorithms, but it still cannot make the writing pen itself accurately detect the writing track, and needs a large number of sensors at the bottom or side. It can be seen that how to enable the writing pen to accurately detect the writing track is a major problem that engineers need to solve. Contents of the invention [0003...
