Embodiment approach 1

[0049] figure 1 It is a diagram showing an example of the appearance of the gesture input device 100 according to Embodiment 1 of the present invention and an interface with related devices. The video display device 110 is connected to an antenna for receiving broadcast programs. In addition, in the present embodiment, one or more user detection cameras 101 and the like are provided above the video display device 110 . The gesture input device 100 controls the video display device 110 using the position, movement, or physical characteristics of the user detected by analyzing the image information captured by the user detection camera 101 . That is, gesture input device 100 generates a control signal for controlling an object device such as video display device 110 based on a user's gesture.

[0050] In addition, the gesture input device 100 may control the video display device 110 based on the position or movement of the user's hand holding the gesture input remote controlle...

Embodiment approach 2

[0119] Next, Embodiment 2 of the present invention will be described.

[0120] Figure 8 It is a diagram showing a typical usage scene of the gesture input device according to Embodiment 2 of the present invention. In this embodiment, a block diagram showing the functional structure of the gesture input device 100 and figure 2 They are the same, but part of the functions of the guide image generation unit 104 and the intended action component detection unit 105 are different. Components other than the guide image generation unit 104 and the intended action component detection unit 105 have the same functions, and therefore description thereof will be omitted.

[0121] Figure 8 (a) shows a state where the first gesture guide image 402 generated by the guide image generator 104 is displayed on the screen 108 immediately after the gesture start detection unit 103 detects a hand movement component indicating the start of a gesture gesture.

[0122] here, as Figure 8 As sho...

Abstract

A gesture input device (100) comprises: a coordinate input detection unit (102) for sequentially detecting the coordinates corresponding to the positions of a user's hand; a gesture start detection unit (103) for detecting, from the detected first coordinate sequence, a component indicating a first hand motion intending the start of a gesture; a guiding image generation unit (104) for, when the component indicating the first hand motion is detected, generating a gesture guiding image for guiding the user to perform a gesture including a second hand motion; an intentional motion component detection unit (105) for detecting, as an intentional motion component, a component indicating the second hand motion from the second coordinate sequence detected after the gesture guiding image is displayed on a screen (108); and a control signal generation unit (106) for, when the intentional motion component is detected, detecting a component indicating the hand motion corresponding to the gesture from the second coordinate sequence and generating a control signal according to the detection result.

Description

technical field [0001] The present invention relates to a gesture input device that recognizes hand movements such as a user's hand swing as a gesture, and controls an object device based on the recognized gesture. Background technique [0002] Conventionally, there have been proposed gesture input devices capable of intuitively inputting the movement of a pointer for selecting an item on the screen or the movement of the item itself in a device equipped with a Graphical User Interface (GUI: Graphical User Interface). An operation to move on the screen. In these gesture input devices, a user moves a pointer or an item on a screen intuitively by moving his hand. Therefore, compared with conventional input devices such as a keyboard and a mouse, the gesture input device has an advantage that no training for familiarization is required and anyone can operate it as desired. Furthermore, among these gesture input devices, there has been proposed a device that does not need to h...
