Description

Technical Field

[0001] This utility model relates to the field of multimedia technology, specifically to a digital exhibition interactive device based on human body sensing. Background Technology

[0002] In traditional multimedia systems such as projection and wall-mounted interactive displays, touch recognition technologies based on sensors such as infrared frames, cameras, or radar have stringent requirements regarding the flatness of the interactive surface. Existing solutions struggle to achieve accurate touch positioning in complex three-dimensional environments such as walls and floors with uneven structures or physical obstacles, severely limiting the expansion of application scenarios. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a digital exhibition interactive device based on human body sensing, which solves the problem that existing multimedia systems have difficulty in achieving accurate touch positioning in three-dimensional space.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A human body sensing-based digital exhibition interactive device includes a multimedia display screen, a host computer, a slave computer, touch devices, and conductive objects. There are multiple touch devices and conductive objects, and they correspond one-to-one. The touch devices are directly installed on the corresponding conductive objects or connected to the corresponding conductive objects through extension wires. The touch devices are signal-connected to the slave computer, and the slave computer is signal-connected to the host computer through a communication connection line. The host computer is signal-connected to the multimedia display screen.

[0006] Preferably, the conductive object is a conductor display model or a conductor display board.

[0007] Preferably, the touch device includes a positive pin, a negative pin, and a signal output pin, which are respectively connected to the corresponding pins of the lower-level machine.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] (1) This utility model receives human signals from touch devices or conductive objects outside the multimedia display screen without direct contact with the multimedia display screen. Because it is connected and transmitted through electronic signal cables such as extension wires and communication cables, it has the ability to adapt to complex surface environments and complete non-planar three-dimensional space interaction. It has a wide range of applications and solves the problem that existing multimedia systems are difficult to achieve accurate touch positioning in three-dimensional space.

[0010] (2) By setting up a touch device or conductive object, the human body forms a charge difference change when it touches the touch device or conductive object. The lower computer can identify the change with high precision and convert it into a digital signal to achieve fast and high-sensitivity response control with the multimedia display screen.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1 As shown, this utility model provides a technical solution: a digital exhibition interactive device based on human body sensing, including a multimedia display screen 1, a host computer 2, a slave computer 3, a touch device 4, and a conductive object 5. There are multiple touch devices 4 and conductive objects 5, and they correspond one-to-one. The touch device 4 is directly installed on the corresponding conductive object 5 or connected to the corresponding conductive object 5 through an extension wire 6. The touch device 4 is connected to the slave computer 3 by signal. The slave computer 3 is connected to the host computer 2 by signal through a communication connection line 7. The host computer 2 is connected to the multimedia display screen 1 by signal.

[0015] The conductive object 5 is a conductor display model or conductor display board. In interactive displays in various venues such as exhibition halls, museums, and science and technology museums, the conductive object 5 can be made into the corresponding exhibit models or exhibit display boards in exhibition halls, museums, and science and technology museums. The touch device 4 includes a positive pin, a negative pin, and a signal output pin, which are respectively connected to the corresponding pins of the lower-level machine 3. When the exhibit model or exhibit display board is touched, the touch device 4 will output a high-level signal to the lower-level machine 3 due to the potential change.

[0016] Working principle:

[0017] When a human touches a conductive object 5 or a touch device 4, the touch device 4 will output a high-level signal to the lower-level computer 3 due to the change in potential. The lower-level computer 3 receives the touch analog signal output by the touch device 4 and converts it into a digital signal and transmits it to the upper-level computer 2. The upper-level computer 2 drives the interface and animation content of the multimedia display screen 1 to respond according to the preset instructions, thereby completing the non-planar three-dimensional spatial interaction.
