Abstract

A determination device for determining an intuitive cut gesture and a method for controlling the determination device are provided.
An extraction unit extracts a shape of an operator's hand from an image acquired by an acquisition unit. The recognition unit 120 determines what kind of gesture has been made from the shape of the hand extracted by the extraction unit 110. When the determination unit determines that a gesture for shifting from the V sign or the V sign to the closed V sign is performed, the program execution unit 130 executes the program assigned to the cut instruction.

Description

The present invention relates to a determination device that determines a command by an operator's gesture and a control method for the determination device.

There is a technique for determining an instruction by an operator's gesture.

JP2005-057416

However, it is not possible to determine a cut command intuitively performed by the operator.

SUMMARY OF THE INVENTION An object of the present invention is to provide a determination device for determining a cut command intuitively performed by an operator, and a control method for the determination device.

A determination apparatus for determining an instruction by a gesture , comprising: a recognition unit that recognizes the gesture; and a program execution unit that executes a program, and the program execution unit when the recognition unit recognizes a gesture for closing a V sign A determination apparatus is provided that executes a program assigned to a cutting instruction .

A method for controlling a determination apparatus for determining a command by a gesture, wherein a recognition unit recognizes a gesture for closing a V sign, and a program execution unit recognizes a gesture for the recognition unit to close the V sign. There is provided a control method for a determination apparatus , comprising a program execution step for executing a program assigned to a cut instruction .

It is possible to provide a determination device that determines a cutting command intuitively performed by an operator, and a control method for the determination device.

FIG. 1 is a configuration diagram of a determination apparatus 100 according to an embodiment of the present invention. The determination apparatus 100 includes an extraction unit 110, a recognition unit 120, a program execution unit 130, and an acquisition unit 140.

The extraction unit 110 extracts the shape of the operator's hand from the image acquired by the acquisition unit 140.

The recognition unit 120 determines what gesture the operator has made from the shape of the operator's hand extracted by the extraction unit 110.

The program execution unit 130 executes the program assigned to each gesture based on the determination result of the recognition unit 120.

FIG. 2 is a flowchart showing the operation of the determination apparatus 100.

The shape of a hand that is extended by holding the thumb, ring finger, and little finger of one hand and opening the index and middle fingers is called a V-sign. (Figure 3)

The shape of a hand extended by holding the thumb, ring finger, and little finger of one hand and contacting the index and middle fingers is called a closed V-sign. (Fig. 4)

A gesture for shifting from a V sign to a closed V sign is called a gesture for closing the V sign.

The extraction unit 110 extracts the shape of the operator's hand from the image acquired by the acquisition unit 140. (Step S210)

The recognition unit 120 determines whether the shape of the hand extracted by the extraction unit 110 is a V sign. (Step S220)

When the recognition unit 120 determines that it is not a V-sign (step S220; NO), the extraction unit 110 extracts a hand shape. (Step S210)

When the recognizing unit 120 determines that the sign is V (step S220; YES), the extracting unit 110 extracts the shape of the hand. (Step S230)

When it is determined that the recognition unit 120 has the closed V sign (step S240; YES), the program execution unit 130 executes the program assigned to the cut command. (Step S250)

When it is determined that the recognition unit 120 is not a closed V sign (step S240; NO), the recognition unit 120 determines whether it is a V sign. (Step S260)

When the recognition unit 120 determines that the sign is a V sign (step S260; YES), the extraction unit 110 extracts the shape of the hand. (Step S230)

When the recognition unit 120 determines that the sign is not a V sign (step S260; NO), the determination apparatus 100 ends the operation.

The gesture of closing the V sign reminds the operator of the image of scissors closing. For this reason, the operator intuitively understands that the gesture for closing the V sign is a cut command.

A cut command is assigned a command associated with the words scissors and cut. For example, digital information such as text, images, music, etc., trimming, deleting, displaying menu screens and tools related to cutting, specifying the cutting range, disconnecting networks and communications, disconnecting, separating, and supplying physical connections There are stop, silence, and object cut.

Also, the V sign gesture reminds the operator of scissors. For this reason, when the recognition unit 120 determines that the sign is V (step S220; YES), the program execution unit 130 may execute the program assigned to the cut command. (Step S250)
