Automatic variable stroke type handwriting input device

Abstract

The invention provides an automatic variable stroke type handwriting input device. The device comprises portable electronic equipment and a handwriting pen, wherein the stroke type of the handwriting pen is automatically changed according to a relative included angle between the handwriting pen and a handwriting plane of the portable electronic equipment. The stroke type is set to be changed under the following conditions: the handwriting pen is in a handwriting state; and the handwriting pen is in three angle scopes and is continuously maintained for T seconds. The device has the advantages that the stroke type of the handwriting input can be automatically varied, so that the additional operations of users can be reduced, and user experiences are improved; and the stroke type variation based on relative included angle variation satisfies the pen holding habits of the users, and the users can be adapt to the use without additional learning.

Description

technical field [0001] The invention relates to a computer peripheral device, in particular to a handwriting input device. Background technique [0002] At present, handwriting input has been applied to more and more portable electronic devices. Handwriting input devices include portable electronic devices and stylus, and the degree of automation of stylus is getting higher and higher, providing a good user experience. Document CN1598869A discloses a stylus that can simulate different strokes. Its main idea is to change the strokes according to the pressure on the tip of the stylus, and only involves the thickness, thickness, etc. of the strokes, but does not involve different types of pens. For example, the words written by a hard pen and a soft pen are different. For example, no matter how thick a ballpoint pen or pencil is, it is not as thick as a brush. Change the thickness within the range of the brush, and cannot jump out of this range. Therefore, the drawback of thi...

Therefore, the disadvantage of this technique is that it cannot automatically change the type of stroke
