Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a remote control method that does not use handheld devices.

(b) Conventional technology As is well known, the conventional method for remote 1i operation is to use a handheld device (hereinafter referred to as a remote control), but there are some methods that do not use a remote control. It is. Typical examples are listed below.

(1) Operation method using the sound produced by clapping hands.

(2) A method of sensing and manipulating the approach of objects or people using ultrasonic waves.

(3) How to create audio separately.

(C) The problem to be solved.

The problems to be solved by the present invention will be broadly categorized into two and will be explained.

(1) Problems with the conventional method using a remote control.

1) Both hands or one hand is occupied to hold and operate the remote control.

■) In order to operate the remote control, it is necessary to concentrate the line of sight on the remote control operation section.

i) Remote controllers tend to be smaller and lighter, and there is a risk of them being misplaced or damaged by falling.

iv) Frequent need to operate switches, etc.

ν) When operated by many people at the same time, multiple remote controllers are required, which increases the price.

vi) There are cases where the remote control cannot be used due to problems such as environmental resistance and surrounding conditions.

(2) Spider: Problems with the conventional method that does not use a spider.

I) Methods (1) and (2) listed in the prior art section do not allow straightforward operation.

ii) Method (3) listed in the prior art section has the following problems.

■There is a risk of malfunction due to the influence of ambient sound.

■u) There are large individual differences in II, and there is a risk of erroneous operation.

■There is no universal life.

(dJ　To-dan trying to solve problems.

The following methods can be used to solve these problems.

(1) The opening and opening of the eyelids or mouth is used as a signal.

(2) Lower the arms 1ζ up, front and back, left and right, and change the shape to 18
number.

(3) The bending or stretching of each finger of the hand is used as a signal.

An analysis of these results is as follows.

1) Method (1) has little change in form, so-called information amplification.

1i) Is method (2) more sensitive than method (1)? Most 1) are generally used as 0-hand flags, etc., which cannot be said to last for 1 minute, but they are used for television receivers (hereinafter abbreviated as 'rV), etc.
It is not suitable for short-distance operations.

*For method i>(3), one finger has at least 1 bit, and each finger has 5 bits.
It can be interpreted as a t= signal of about 20 bits, and there are many information mice, so it is convenient as a signal source.

(e) Function As explained above, at least 5-bit FA signals, so-called 32 kinds of signals, can be obtained with one hand by bending and stretching the fingers. Also, if you need a lot of information, change the direction of your hand...depending on whether your fingers are above or below the back of your hand, or on the right or left...the number will be 4 times as large as 20 piti Δ. If both hands are used, the signal will be doubled to 40 bits. However, even if you exclude hand shapes that are difficult to create in reality, such as stretching only the ring finger and bending all the other fingers, it can still be used as one level signal with a large number of bases.

In the above explanation, the phrase "at least 5-bit signal with 1g hand" means that you can make a circle with your thumb and forefinger...so-called OK.
This is because there are other forms such as marks, etc., and the number of bits is further increased as necessary.

<f> Example The order will be explained based on the case where the method according to the present invention is used as a remote control means for a TV.

IJ is a block diagram showing the configuration of an embodiment of the present invention, and the subject 1 (in this case, a hand) is the optical part 2.
An image of the subject 1 is created on the image sensor 3 via the image sensor 3, taken out as an analog electrical signal, and amplified in the signal processing unit 4, subjected to analog/digital conversion, shaping, noise removal, etc. , the background etc. are removed by the feature extraction unit 5, and the hand shape! Buishi is finally extracted. The extracted signals are temporarily recorded in the memory 6, and are combined with several types of template signals recorded in the memory 6 in advance and the recognition unit 7.
The signals are compared in the signal converter 8 and converted into operation No. 13 corresponding to the matching template, resulting in an operation signal of 1゛v.

These series of operations are controlled by the CPU section 9 of the microcomputer-1.
