Angle detection method and angle detection device

Abstract

An angle detection method and an angle detection device are disclosed. The angle detection method includes: when a touch is detected, recording the position of the touch pen on the touch panel and the position of the touch panel of the user's hand on the touch panel. The distance between the positions of the equivalent points; the user's pen-holding data and the angle detection model are retrieved from the storage unit, and the pen-holding data includes the vertical distance between the holding position of the user holding the stylus and the touch panel when touched distance and the projected distance between the holding position and the equivalent point; according to the distance and the holding pen data, the angle detection model is used to obtain the inclination angle of the stylus on the touch panel; and the line in the storage unit is obtained according to the inclination angle Obtain the display line width corresponding to the tilt angle from the width table, and the width of the line displayed on the touch panel is the display line width. When using the old stylus to touch, the tilt angle can be quickly recognized, so that the corresponding line width can be displayed on the touch panel, the cost can be reduced, the power consumption of the stylus can be saved, and the versatility is strong.

Description

technical field [0001] The present invention relates to the technical field of touch control, and more particularly, to an angle detection method and an angle detection device. Background technique [0002] At present, with the development of displays of portable electronic devices, more and more users begin to use a stylus to write or draw patterns on the display, which can improve the accuracy of writing or drawing input. [0003] When the existing stylus writes on the display, it is often written in a tilted manner. For example, the active pens (active capacitive pens) produced by Wacom and Microsoft both support Tilt detection (tilt detection) and detect touch. The inclination angle of the control pen (or active pen) relative to the display can better sense the user's writing habits, and perform touch adjustment and other tasks. And for some stylus, the touch pressure when using the stylus and the inclination angle of the stylus will affect the line display on the touch...

And for some stylus, the touch pressure and the tilt angle of the stylus when using the stylus will affect the line display on the touch panel

[0004] However, the detection method of tilt angle currently used is a relatively traditional detection method, which requires the use of N-axis gyroscopes, gravity sensing components and other instruments, which require precision detection instruments and amplifier circuit design, etc., which cause inconvenience to the measurement. Therefore, it takes a lot of manpower and material resources to measure the inclination angle to display lines with corresponding line widths on the display panel, and it cannot save power consumption.
