Capacitive finger navigation remote controller

Abstract

The invention discloses a capacitive finger navigation remote controller, which comprises a main controller, an ordinary press key, a capacitive finger navigation module and an RF (radio frequency) receiving and sending module, wherein the ordinary press key is connected with an I / O (input / output) port of the main controller, the capacitive finger navigation module comprises four groups of respective independent electrodes and signal processors, the four groups of electrodes are in lattice-shaped distribution and arrangement and are connected with the signal processor, the signal processor sends the electrode signals to the main controller after processing the electrode signals, the main controller reads operating signals of the capacitive finger navigation module and ordinary press keys, the operating signals are sent to terminal equipment by the RF receiving and sending module after being processed, the RF receiving and sending module adopts an RF4CE communication protocol to carry out two-way communication with the terminal equipment. The capacitive finger navigation press keys are integrated on the ordinary remote controller, the mouse operation and control function on a controlled terminal is realized. The defects of the infrared remote control technology are overcome through the adoption of the RF4CE communication protocol.

Description

technical field [0001] The invention relates to a remote controller, in particular to a capacitive finger navigation remote controller and a control method, belonging to the technical field of remote control equipment. Background technique [0002] With the increasing popularization of digital TV and computers, the requirements for the matching remote control equipment are also getting higher and higher. At present, the existing remote controllers with common button functions can no longer easily meet the user's needs for controlling electronic products. For example, there are display menus on the screens of a large number of terminal devices (televisions, computers). Traditional remote controllers can only use direction keys to control the cursor on the screen to move or highlight in the horizontal or vertical direction. point to move to another point, let alone move arbitrarily on the screen, resulting in cumbersome and time-consuming operation steps when the user uses th...

At present, the existing remote controllers with ordinary button functions can no longer easily meet the user's needs for controlling electronic products.

For example, there are display menus on the screens of a large number of terminal devices (televisions, computers). Traditional remote controllers can only use direction keys to control the cursor on the screen to move or highlight in the horizontal or vertical direction. point to another point, let alone move arbitrarily on the screen, resulting in cumbersome and time-consuming operation steps when the user uses the remote control device to control the terminal device, which cannot meet the user's needs for simple and fast operation of the terminal device
