Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] 1 Position the pen tip at the center of the pie-shaped menu, the computer reads the input information of the pen, and obtains the current altitude information of the pen and the inclination information azimuth;

Abstract

The invention belongs to the field of human-computer interaction, in particular to a method which carries out cake-shaped menu selection by the obliquity information of a pen. In the method, the penpoint of the pen equipment is positioned at the center of the cake-shaped menu; based on the three-dimensional direction information of the pen, plane projection mount of the pen equipment in a three-dimensional coordinate and an angle of the plane projection mount and the positive direction of the coordinate axis are gained to realize the selection of the cake-shaped menu. When the penpoint carries out drawing or interaction tasks, in order to trigger a menu option at the same time, the pen is inclined without moving the penpoint, when the top end projection of the pen touches the edge of the menu option, the menu option is selected, the tasks of instruction selection and direction control can be completed by completely freely using a single hand at the same time, thus leading the advantage of selection operation which is carried out when moving or writing to be especially obvious.

Description

Technical field [0001] The invention belongs to the field of human-computer interaction, and specifically relates to a method for selecting a pie-shaped menu by using the inclination information of a pen. Background technique [0002] Pen writing and posture are the two basic modes of pen interaction. Usually pen input devices not only provide the position information of the pen tip, but also provide extended information, such as writing pressure, three-dimensional direction and three-dimensional rotation information. The traditional pen-style user interface uses a lot of information about the pen tip, such as the position of the pen tip, pressure, and so on. [0003] At present, the existing research work in pen writing and posture includes: Li’s research pointed out that in the pen interface, there are 5 technologies that can be used to switch between writing and posture, including mode switching based on pen pressure This is an implicit mode switching (Reference: Li, Y., Hinck...
