Embodiment 1

[0050] The first embodiment includes a projection device and an image acquisition device. The projection device projects a pattern with position coding information, the user stands in front of the projected image, and the image acquisition device collects a captured image containing the complete human body and position coding information, and transmits the captured image to the projection device. The projection device recognizes human body characteristic parameters according to the captured image, and the human body characteristic parameters include but are not limited to human face, shoulder height, arm length, human eye height, and human jaw. And determine the height of the upper edge of the user's operable area (position in the image) according to the human body feature parameters, which is recorded as the operable height position h0 corresponding to the human body.

[0051] like Figure 4 As shown, the projection device projects a display image with an interactive area, a...

Embodiment 2

[0053] The second embodiment is similar to the first embodiment, except that the projection device that cannot be adjusted automatically and mechanically is used in the second embodiment. In this embodiment, the first adjustment range is h2 (h1 and h2 coincide), and the second adjustment range That is h4 (h4 and h3 coincide). When h0 is greater than h2, the overall interactive area of ​​the initial proportion is below the manipulative height of the human body, and no adjustment is made at this time; when h0 is less than h2 and greater than h4, adjust the interactive area through the projection device and move down in the projection area or press When the scale is reduced, the interactive area can be located below the human body's operable height; when h0 is less than h4, the projection device cannot adjust the interactive area to be below the human body's operable height through its own structure or program, and the user is prompted to use pads or other external devices. Insta...

Embodiment 3

[0058] In the third embodiment, the multimedia interaction device adopts a touch screen device. In this embodiment, as Figure 7 As shown, it is executed by a touch screen device such as a liquid crystal touch screen or an LED touch screen, and the user's operable height is collected by a touch sensor. Generally, a multi-touch screen is supported or the user's characteristic parameter information is collected by an infrared grating. Specifically include the following steps:

[0059] Step 1: Obtain human body characteristic parameters, and determine the corresponding manipulable height of the human body.

[0060] exist Figure 8 Among them, the E area is the touch display area of ​​the touch device, and the D area is the interactive area in the touch display area that can be operated by the corresponding user. The area of ​​the D area is less than or equal to the area of ​​the E area. In this embodiment, the user inputs the human body characteristic parameters through an in...

Abstract

The invention relates to the technical field of multimedia control, and discloses a method and device for automatically adjusting an interactive area based on human body characteristic parameters, which is executed by a multimedia device capable of projecting or displaying an interactive area. The corresponding manipulative height of the human body; A2, display the display screen including the interactive area, obtain the first adjustment range of the upper edge of the interactive area, and obtain the second adjustment range of the lower edge of the display screen. The beneficial effects are as follows: the present invention collects the user's human body characteristic parameters for users of different heights, determines the operable heights of different users according to the human body characteristic parameters, and determines the multimedia according to the comparison of the operable heights with the first adjustment range and the second adjustment range. The adjustment scheme in which the equipment mechanical and software cooperate with each other ensures as much as possible that users of different heights can easily operate the interactive images when using the same interactive multimedia.

Description

technical field [0001] The invention relates to the technical field of multimedia control, in particular to a method and device for automatic adjustment of an interactive area based on human body characteristic parameters. Background technique [0002] With the development of image recognition technology and object detection and positioning technology, multimedia interactive systems based on projection or touch display screens have been widely used. [0003] During the operation of the existing multimedia interactive system, it is found that due to the different height ratios of different users, the image display area can often only be moved within a relatively fixed range. In the prior art, the projector or touch screen is often manually controlled Height, change the height of the projected or displayed image to suit the height of different users. [0004] More specifically, as figure 1 As shown, area C is the projected image area, area D is the interactive area, and the ...
