Embodiment Construction

[0059] See figure 1 , figure 1 It is a schematic diagram of the receiving strength of the remote controller and its remote control signal according to an embodiment of the present invention. figure 1The remote controller 110 includes a plurality of signal transmitting units, and each signal transmitting unit transmits a remote control signal, and the remote control signal can be an infrared signal or an ultrasonic signal. To simplify the schema, figure 1 Only the signal transmitter 120 of one of the signal transmitting units is shown.

[0060] The remote control signal in this embodiment has directivity, and the pointing direction of each remote control signal is the pointing direction of the signal transmitter in the signal transmitting unit corresponding to the remote control signal. For example, the pointing direction of the signal transmitter 120 is marked as 130 . If the distance is the same, the strength of the remote control signal received by the receiver is the st...

Abstract

The invention discloses a remote controller, a corresponding receiver thereof and a corresponding remote control method thereof. The remote control method comprises the following steps: the receiver receives remote control signals emitted by the remote controller, the remote control signals are separated, relative intensities of the remote control signals are obtained through calculating, a directional coordinate of the remote controller is generated according to the relative intensities, and various remote control motions can be executed according to the directional coordinate of the remote controller.

Description

technical field [0001] The present invention relates to a remote controller and its corresponding receiver and remote control method, and in particular to a remote controller that transmits multiple remote control signals in multiple different directions, its corresponding receiver and remote control method. Background technique [0002] Now the TV can not only watch TV programs, but also watch photos, play games, and access the Internet. These applications require more user interaction actions, such as allowing the user to move a cursor on the screen, or click on the location of the cursor. Traditional push-button remote controls usually need to press many different keys in these applications, which is very inconvenient. It will be much more convenient if the position of the cursor on the screen can be directly controlled by the direction pointed by the remote controller. [0003] The current existing method is to install several remote control signal receivers on the tel...
