Human-machine interaction input device and input method

Abstract

The invention discloses a human-computer interaction input device and an inputting method, wherein the device includes a sliding blade, a rebound mechanism and an optical module. The sliding blade which is provided with an original position and a deviating area is used for the movement in the deviating area under the exogenic action; the rebound mechanism is used for enabling the sliding blade tomove back to the original position under the condition of removing the external force; the optical module which is arranged under the sliding blade ensures the moving information of the sliding bladethrough sending out a ray and receiving the ray reflected by the sliding blade, and ensures the moving speed and the moving distance of a cursor in a graphical interface according to the calculation of the moving information through the electronic part in the module. The invention realizes the full screen control for the cursor only by occupying very small space, and the adopted optical engine haslow cost and high stability. The invention can be widely applied to the device which has limited space such as a notebook PC, a remote-control unit, and even a mobile phone.

Description

technical field [0001] The invention relates to computer input and output equipment, in particular to a novel human-computer interaction input device and input method. Background technique [0002] Portable electronic devices with larger screens (12” or larger) and higher computing speeds represented by notebook computers all use a graphical interactive interface (GUI), while free-path cursor control devices such as mice are graphically interactive. The most important input and output control device for the interactive interface. There are currently two main types of free path cursor control devices: [0003] 1) Touchpad (TouchPad) based on capacitive sensing principle; [0004] 2) Pointing stick (TrackPoint) based on the principle of pressure sensing; [0005] The working principle of the touch panel is to use the moment when the user's finger touches the touch panel to generate a capacitive effect, so the position of the finger can be judged by the change of the capacita...
