Input device and input method

Abstract

It provides an input device and its method. It comprises at least an input interface, a processing unit and an execution unit. The input interface is similar to a touch screen or a touch panel to allow the user to input by a finger or touch pen to show the hand writing. Processing unit can analyze the handwriting. Last, the execution unit will execute a preset function based on the comparison of the bend trend.

Description

Technical field: [0001] The invention relates to an input device and an input method thereof, in particular to the technical field of handwriting input. Background technique: [0002] Please refer to FIG. 1 , which is a schematic diagram of controlling an electronic device in the prior art. In FIG. 1 , a user 10 has to use his head, face, eyes or hands to control the functions of the electronic device 11 . In this example, the electronic device 11 uses a camera 12 to capture body images of the user 10, and determines which default function should be executed based on the degree of change between the captured images. For example, use the left and right rotation of the head to adjust the angle of the display screen on the electronic device 11, or use the movement of the hand or the change of the gesture to drive the electronic device 11 to activate or deactivate some multimedia functions, or use the user's 10 The eyeballs rotate to control the control cursor on the electroni...

Problems solved by technology

[0005] However, in addition to ensuring a high recognition rate for the above-mentioned conventional technology, and related hardware input equipment, such as the above-mentioned video camera, microphone or voice input device or touch-sensitive writing pad, all cause inconvenience to the portability of the electronic device.

In addition, when the user is operating a portable electronic device while walking, it seems that it is quite inconvenient to use the stylus to touch the small text or menu on the display screen on the touch screen.

Or, when a user receives a personal important text message through their electronic device during a work meeting, it seems that they cannot use body image, use voice recognition, or use a stylus to click on a relatively small phonetic square or use an error The extremely troublesome handwriting recognition of word selection to manipulate the response of its electronic device

Or, when the user needs to use an engineering computer software, but needs to use his stylus or other peripheral input devices such as a mouse, from the start / program set / .. on the display screen as if from the sea Only by selecting one by one to find out the software, this will also cause considerable inconvenience to users

Furthermore, when the user wants to use a portable electronic device, such as a personal digital assistant (PDA), to listen to music with the audio in the car while driving, and temporarily needs to adjust the volume of the portable electronic device, At this time, it also causes considerable inconvenience to the user. For example, the user needs to use the stylus to click the small volume icon on the top of the screen to control the volume by dragging.
