Handwriting input device capable of measuring lateral pressure

Abstract

The invention provides a handwriting input device capable of measuring lateral pressure, belonging to input information entry equipment. The device comprises a pressure-bearing component, a signal inductive component, a pen core, a lateral stress block and a penholder, wherein the inner side of the front end of the penholder is taken as a lateral stress surface; the penholder is internally provided with the pen core, the front end of the pen core is provided with the lateral stress block, and the lateral stress block is contacted with the lateral stress surface; the signal inductive componentand the pressure-bearing component are arranged in the penholder; and the penholder can fix the signal inductive component to carry out electromagnetic induction with a coil of a handwriting board and calculate an inclination angle of the penholder according to an induced signal. In the invention, the inclination angle of a pen can be measured by means of electromagnetic induction generated by the signal inductive component and the coil of the handwriting board, the penholder is internally provided with the lateral stress surface, and the lateral stress block is fixed on the pen core, thus being capable of controlling a writing and drawing force more meticulously, truly showing skills and purposes of an author, not affecting axial pressure measurement, and having simple structure, low cost and good application value.

Description

technical field [0001] The invention belongs to information input equipment, and relates to a handwriting input device, in particular to a handwriting input device capable of measuring lateral pressure. Background technique [0002] At present, there are various types of input devices for computers, such as mice, keyboards, scanners, etc., among which handwriting input devices are very important. The most common handwriting input device is an electromagnetic tablet, which consists of a digital tablet and a stylus. The stylus is used as the user's writing tool, and its comfort and input efficiency determine the performance of the entire device. [0003] Chinese patent CN01145283 discloses a stylus, which consists of a pen housing and internal components. The internal components include a magnetic component and an inductance-capacitance resonant circuit. The position change of the magnetic component causes the inductance value of the resonant circuit and the frequency of the ...

AI Technical Summary

Problems solved by technology

This handwriting input device can only sense the pressure perpendicular to the pen tip, that is, the pressure in the axial direction of the stylus, and cannot sense the pressure in other directions of the tablet.

[0005] At present, most stylus can only measure the pressure in the axial direction of the stylus, but not the lateral pressure of the stylus
