Digital pen with tracing path and pressure sensor

Abstract

The digital pen of the present invention includes one refill with path tracing assembly, which detects the shift of the nib in some direction through a light signal; and one pressure sensing assemblyconnected with the refill to detect the relative shift of the refill applied by some pressure to the digital pen and to convert the pressure into electric signal. The digital pen may be used in tracing hand writing input path and sensing hand's pressure.

Description

(1) Technical field [0001] The invention relates to an indicator tool, in particular to a digital pen capable of handwriting input. (2) Background technology [0002] Pointing devices, such as mice or trackballs, are well-known peripheral tools in the data processing environment. For example, the pointer tool allows the manipulation and use of cursors on the display screen of a personal computer or workstation. The operation and application of the so-called cursor includes the quick repositioning action of the cursor from one place to another on the display screen, and the action of selecting a target object on the display screen. [0003] In the environment of a conventional electromechanical mouse, the user controls the cursor by moving the electromechanical mouse on a reference surface, such as a rubber mouse pad, and a moving direction and distance of the cursor on the display screen can be proportional to The movement of the electromechanical mouse on it. However, th...
