Embodiment approach

[0035] (1) Use your fingers to flex or tap on the pressure sensor group formed by multiple pressure sensors, use the pressure sensor to collect the pressure analog signal, and then use the A / D converter to convert the pressure analog signal collected by the pressure sensor group into digital signal, the main control module receives the digital signal, and records the number N of sensors that detect the pressure value, and the time T when each sensor detects the pressure value i and the number of times each sensor detects a pressure value C i ; Among them, the three sensors from the tip of the pen to the tail of the pen are respectively recorded as the first, second and third sensors, and the corresponding moments when the pressure value is detected are respectively T 1 ,T 2 ,T 3 , the number of detected pressure values ​​is C 1 , C 2 , C 3 ; The time interval threshold for completing the pen scratching action is T;

[0036] (2) Within the time interval threshold T, if N=...

Abstract

The present invention provides an electronic stylus for recognizing finger-scratching and pen-tapping actions, including a pen case, characterized in that a pressure sensor group is embedded on the pen case, and a main control module and an A / D converter are arranged in the pen case. The pressure sensor group is connected to the main control module through the A / D converter, the main control module is connected to the wireless transmission module, and the power supply module is connected to the main control module and the wireless transmission module. The present invention can realize the command operation through the action of scratching the pen and tapping the pen of the finger.

Description

technical field [0001] The invention relates to an electronic stylus, in particular to an electronic stylus and an input method for recognizing the actions of fingers scratching and tapping the pen. Background technique [0002] In the pen-type interactive system, users can freely realize functions such as text writing, graphics drawing and command operation by using the pen-type device. With the development of pen-type interactive technology, pen-type devices are gradually being popularized in personal computers, tablet computers and mobile phones. [0003] However, when people use pens to interact with computers, there are still the following disadvantages: (1) In traditional pen-based interactive systems, the pen only supports two-dimensional coordinate information of the pen tip, and the parallel input capability is relatively weak; When browsing webpages and documents on a mobile device, the page cannot be scrolled as fast as the mouse wheel, and the page can only be t...
