Handwriting input method and device based on temperature touch

Abstract

The invention provides a handwriting input method and device based on temperature touch. The method comprises the steps of parameter initialization, data reading, acquisition of a temperature rise maximum value, fingertip touch judgment, acquisition of a temperature rise maximum value during movement, fingertip movement judgment and numeric character recognition. The device comprises a controller, and a temperature sensing array and a memory which are connected with the controller, wherein the controller comprises an initialization module, a data reading module, a temperature acquisition maximum value module, a fingertip touch judgment module, a movement acquisition module, a fingertip movement judgment module and a number recognition module. The handwriting input method and device based on temperature touch do not need interaction between any special stylus and a digital converter, working normally is realized even when a screen is wet, and a more attractive substitute for the traditional man-machine interaction interface is provided.

Description

technical field [0001] The invention relates to a handwriting input method and device, in particular to a temperature-tactile-based handwriting input method and device. Background technique [0002] With the rapid development of science and technology, the handwriting input devices of electronic products are increasingly diversified. Many sensor-based handwriting input devices have been developed, such as myoelectric sensors, visual sensors, inertial measurement devices, tilt acceleration sensors, optical axis angle sensors, capacitive sensors, resistive sensors, and writing force sensors. Pen computer technology has replaced the traditional human-computer interaction interface and has been successfully applied to notebook computers. At present, the more common touch screens are resistive screens and capacitive screens. Usually, resistive screens are more sensitive to resistance changes caused by different contacts, but a special pen is required to interact with the digitiz...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing resistive screen needs a special pen to interact with the digital converter, and the capacitive touch screen will not work properly when the screen is wet
