Natural interaction pen capable of automatically inputting written contents and handwriting detection method

Abstract

The invention discloses a natural interaction pen capable of automatically inputting written contents and a handwriting detection method. According to writing motion models of human, the interaction pen measures angular velocity information and acceleration information of the motion of a human hand and a human arm in a writing motion process by using sensors in a pen body, and output voltage signals are subjected to low-pass filtering and analogue-to-digital conversion and then are sent to a microprocessor I for calculation of writing motion characteristic quantity and recognition of writing intention and mapped into handwriting information of the written contents; the signals output by the microprocessor I are sent through a data wireless communication module I; the signals sent by the data wireless communication module I are received by a receiving end of a computer host, then processed through a microprocessor II and transmitted to the computer host through a USB interface. The natural interaction pen has the advantages of no need of handwriting panel, independent work, better accordance with the writing operation habit of people, and high portability and universality.

Description

technical field [0001] The invention relates to a computer handwriting input device, in particular to a natural interactive pen for automatically entering writing content and a handwriting detection method. Background technique [0002] Pen input technology has received extensive attention because it conforms to people's writing habits. At present, there are many pen input devices on the market, but most of them are limited to handwriting input on the tablet equipped by the manufacturer. The strokes generated by the points need to be reflected in the computer. This method is an absolute data reflection. If it is separated from the tablet, it will not work at all. At the same time, due to the limitation of the size of the tablet, the movement area of ​​the stylus is limited, and there is no flexibility in the use process. . [0003] There are also people who start from changing the basic shape of the mouse and improve the existing mouse to make it have a pen-like shape for w...
