Patent Application

The present invention relates to a remote control apparatus and method, and more particularly to a secure remote control apparatus and method using motion driving.
At present, a remote controller for remotely controlling an electronic apparatus, e.g. a television, a set-top box, a digital video disk or a conditioner, and so forth, includes plural push buttons, a controller and an infrared transmitter. When detecting a push action happened on one of the plural push buttons, the controller determines a control code corresponding to the push action, and controls the infrared transmitter to transmit an infrared signal to the electronic apparatus, wherein the infrared signal includes the control code.
Since the micro-electro-mechanical component, e.g. the micro-electro-mechanical gyroscope, the accelerometer or the magnetometer/e-compass, and so forth, were available on the market, it has been found that the remote controller, or called the joystick, designed with these components, can be used to play interactive games, so that the design thereof becomes the focus in great attention. However, up to now, the design, people generally conceive, is that the electronic apparatus on the receiving terminal should be changed significantly. For instance, in the hardware aspect, the current infrared receiver is changed into a radio frequency receiver or a Bluetooth receiver; in the software aspect, the traditional simple user interface is changed into a complex graphic user interface. In this way, it is necessary to upgrade the processing unit and the operating system of the remote controller of this type.
Therefore, how to utilize the micro-electro-mechanical component for a remote control to remotely control an electronic apparatus becomes the demand on the market.
It is an object of the present invention to transmit plural infrared signals having different directions in order to ensure that the infrared receiver of the electronic apparatus still can receive a signal associated with at least one of the plural infrared signals when the remote control apparatus is waved. Therefore, it is unnecessary to change the current infrared receiver into the radio frequency receiver or the Bluetooth receiver.
It is therefore an aspect of the present invention to provide a remote control apparatus having a motion. The remote control apparatus includes a determining device and a signaling unit. The determining device produces a first signal in response to the motion. The signaling unit transmits a plurality of signals associated with the first signal, wherein each of the plurality of signals has a respective transmitting direction.
It is therefore another aspect of the present invention to provide a secure remote controller including a determining device and a signaling unit. The determining device generates a message. The signaling unit transmits the message in a first direction and a second direction.
It is still another aspect of the present invention to provide a secure remote controlling method including the following steps. A controlling message is generated. The controlling message is transmitted in a first direction and a second direction.
The foregoing and other features and advantages of the present invention will be more clearly understood through the following descriptions with reference to the drawings, wherein:
The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for the purposes of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
