JP2001175412A - Remote controller for electronic equipment with multi- axial integral acceleration detector - Google Patents

Abstract

PROBLEM TO BE SOLVED: To simultaneously detect the moving amounts of X, Y, and Z directions, and to output them to electronic equipment by using integral two axial or three axial acceleration detector. SOLUTION: A two axial or three axial acceleration detector is mounted in X and Y direction on an inputting device circuit board, and a remote controller is moved vertically and to the right and left instead of a key operation, so that the output of the detector can be calculated, and that the change of the instructing direction can be outputted to the electronic equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device that incorporates an integrated two-axis or three-axis acceleration detector and outputs up, down, left, and right direction information to an electronic device.

[0002]

2. Description of the Related Art Conventionally, a remote control input device operates a push button switch arranged on a front panel, modulates an infrared ray by the signal, and transmits the modulated signal to a device. Taking a TV broadcast receiver as an example, this method is used for functions that are frequently operated, such as changing the reception channel using a numeric keypad or adjusting the volume by operating a scroll key for selecting an up / down direction. It is effective, but when it is necessary to make detailed settings such as adjusting the image quality and sound quality, a selection screen with multiple layers on the screen is called,
It required complicated key operations. Up to now, a method of obtaining the number of scanning lines in a video signal and obtaining position information has been performed.
It has been difficult to employ low-resolution devices for remote control. Also, when it is necessary to mutually operate electronic devices that operate in relation to each other, operate a plurality of remote control devices at hand, or store the instruction content given to each device in one device, Either way, a complicated operation is required, and depending on the situation, there is a possibility that damage may occur due to an erroneous operation.

[0003]

The present invention relates to a two-axis or three-axis
Using an axis acceleration detector, calculating the output of the detector by moving the remote control device up and down and left and right instead of the key operation, and changing the indicated direction,
Output to electronic equipment. As a result, the selection functions displayed on the sub-screen of the television visually match, and the operability is dramatically improved. Also, between the remote control device and a plurality of electronic devices, by storing the individual identification mark of each device in the remote control device, to prevent interference due to crosstalk between devices that cannot be removed from the directional characteristics of the transmitting and receiving elements, It is possible to operate individual devices.

[0004]

The configuration will be described. (A) A two-axis or three-axis acceleration detector is mounted on a circuit board of a remote control device. (B) By changing the direction of the remote control device up, down, left, and right, the resulting two- or three-axis displacement is calculated,
Output as direction signal. If a conventional numeric keypad or the like is installed, it can be used together with key operation. The device is operated as described above.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The biaxial or triaxial acceleration detector used in the present invention can obtain an output with respect to the acceleration of each axis. , A / D conversion circuit converts the directional signal into a required direction signal.

First Example The shape of the device is the same as that of the conventional method. The detector installed in the device detects the XYZ three-way variation by changing the direction of the device up, down, left, and right, but converts this into signals corresponding to the up, down, left, and right angles, and converts infrared and ultrasonic waves. Modulate with the direction signal and transmit. The receiving device can perform the same processing as the signal received by the conventional method. However, if the present invention is applied to a display device of a projector type or a large flat display device, the movement of the body (the movement of the hand) is displayed on the screen The operation feeling can be greatly improved. In practice, even when a wireless structure using infrared rays, ultrasonic waves, or the like is used, the directivity of the transmission / reception surface does not need to be considered as long as the device faces the device.

Second Example In order to apply the present invention to a large number of electronic devices, a special identification mark is determined for each device, mutually transmitted and received, and the device to which the remote control device is directed is individually operated. Can be. The embodiment of the present example is the same as the first example.

[0008]

Although such a simple structure is used, the operability can be further improved while being used in combination with the conventional method, and the application range is wide.
