Track point convenient to operate

Abstract

The invention discloses a track point convenient to operate. The track point is provided with a cylindrical operation portion arranged among keys of a keyboard, the upper side of the cylindrical operation portion is provided with a static touch sensing area with the diameter of 5-10 mm, and the touch sensing area is provided with 10-30 symmetrically distributed first sensing electrodes and second sensing electrodes; the sensing electrodes are connected with an independent touch control IC or share the touch control IC with a touch panel beside the keyboard; the touch control IC determines the moving speed and the direction of a cursor by calculating the distance and direction of a finger touch center point relative to the center point of the touch control sensing area; according to stay states of a finger, a cursor moving instruction or a shortcut key instruction is sent out. According to the track point, a static touch control mode takes the place of the mode that resistance is changed by pushing and pressing in a traditional track point, and fatigue caused by long-time operation can not be generated; besides, response speed is higher; moreover, the track point has single-click, double-click, three-click and roller functions, and has more operation functions than push-press track points in the prior art.

Description

Technical field: [0001] The patent of the present invention relates to the technical field of computer peripheral products, in particular to an easy-to-operate pointing stick. Background technique: [0002] Many notebook computers will be equipped with a pointing stick (commonly known as Little Red Riding Hood) to facilitate the operation of the cursor without leaving the fingers. It is women and children; also, the response speed is not fast, far inferior to the touchpad; moreover, the rubber cover on the pointing stick will become dirty and need to be replaced after a long time, causing inconvenience. Therefore, in addition to the pointing stick, most notebook computers are also equipped with a standard touch panel, which causes repeated investment and wastes, so it is necessary to find a design that is more labor-saving and responds faster. [0003] In fact, the pointing stick is operated in the form of a joystick, and the touchpad can also be operated in the form of a j...

[0002] Many notebook computers will be equipped with a pointing stick (commonly known as Little Red Riding Hood) to facilitate the operation of the cursor without leaving the keyboard. It is women and children; also, the response speed is not fast, far inferior to the touchpad; moreover, the rubber cover on the pointing stick will become dirty and must be replaced after a long time, causing inconvenience

Therefore, in addition to the pointing stick, most notebook computers are also equipped with a standard touchpad, which will cause repeated investment and waste, so it is necessary to find another design that is more labor-saving and responds faster.
