Description

Technical Field

[0001] The utility model discloses a touch device, specifically a novel unilateral human-computer interaction touch device, which belongs to the technical field of electronic equipment and can be widely used in mobile devices, smart homes, automobiles and other fields. Background Art

[0002] A touchscreen is a technology that allows users to control a device or operating system by directly touching icons, buttons, or other operable elements on the display. It has become a widely used interaction method in modern electronic devices, such as smartphones, tablets, computer monitors, and certain home appliances.

[0003] The touch devices in the prior art can be roughly divided into the following main types according to their working principles:

[0004] Resistive touch screens consist of two layers of flexible, transparent resistive film. When a user presses the screen with a finger or stylus, the two layers form contact, changing their resistance and locating the touch position. Advantages include relatively low cost and support for a variety of styluses and gloves. Disadvantages include thickness, susceptibility to scratching, and high light transmittance requirements.

[0005] Capacitive touch screens consist of a capacitive sensing layer and a glass surface. When a finger touches the screen, the current in the capacitive layer changes, detecting and locating the touch location. Advantages include fast response, high touch accuracy, and support for multi-touch. Disadvantages include high price, high requirements for transparent conductive materials, and inability to use traditional styluses.

[0006] Surface acoustic wave touchscreens: These devices transmit ultrasonic beams that reflect off the touch panel surface and detect changes in these beams to locate the touch position. Their advantages include high light transmittance, scratch resistance, and suitability for large touchscreens. Their disadvantages include high cost and sensitivity to ambient noise.

[0007] Infrared (IR) touchscreens use a set of infrared transmitters and receivers to detect when a finger or other object blocks infrared light, thereby determining the touch location. Their advantages are suitability for large screens and immunity to physical damage. Their disadvantages are slower response times and potential for obstruction.

[0008] Currently, most infrared (IR) touch devices on the market are dual-sided or quad-sided, requiring users to install sensors on both sides or all four sides of the screen to achieve touch control. However, this approach increases the cost of the touch device as the number of sides increases, and the installation process becomes more complicated. In some customer scenarios, the presence of the bottom sensor can easily lead to water accumulation and even damage. Summary of the Invention

[0009] In response to the above-mentioned shortcomings of the infrared touch devices in the prior art, such as high cost and complicated installation process, the present invention provides a new type of single-sided human-computer interactive touch device. By combining an infrared LED with a camera structure, it can achieve touch recognition by installing the control device on one side. The single-sided touch device has more advantages than traditional technologies in terms of manufacturing, cost and reliability.

[0010] The utility model solves its technical problem by adopting the following technical solution: a novel unilateral human-computer interactive touch device, the touch device comprising glass, a first camera and a second camera, the first camera and the second camera being arranged above the glass, and both the first camera and the second camera being arranged facing the glass.

[0011] The technical solution adopted by the utility model to solve its technical problems further includes:

[0012] The first camera and the second camera are arranged corresponding to the same side of the glass.

[0013] The first camera and the second camera are arranged at two corner positions on the same side of the glass.

[0014] A light guide strip is fixedly installed on the side of the glass, and the first camera and the second camera are respectively installed at two ends of the light guide strip.

[0015] The touch device also includes a light-emitting LED lamp.

[0016] The light-emitting LED lamp is arranged corresponding to the light guide bar, or the light-emitting LED lamp is directly arranged in the light guide bar.

[0017] The light guide strip, together with the light-emitting LED lamp, the first camera and the second camera are installed above the glass, or on the left or right side of the glass.

[0018] The beneficial effects of the present invention are as follows: the unilateral touch device of the present invention simplifies the existing traditional touch installation and production process, improves the user experience, and the user can realize the human-computer interaction function by simply installing the touch device on either side.

[0019] This single-sided touch device utilizes a reflective design, resulting in an extremely thin and narrow design. This design optimizes both the LED light output surface and the camera light input surface, reducing wasted light and lowering the physical touch height, significantly reducing the risk of stray strokes and improving the writing experience. Because it utilizes a single-sided design, it is waterproof whether installed on the top, left, or right side, improving reliability in actual customer use scenarios.

[0027] This embodiment is a preferred implementation of the present utility model. Other embodiments whose principles and basic structures are the same or similar to those of this embodiment are within the protection scope of the present utility model.

[0028] Please refer to the attached Figure 1 To the attached Figure 5 The utility model mainly includes glass 1, a first camera 3 and a second camera 4. The first camera 3 and the second camera 4 are arranged above the glass 1, and the first camera 3 and the second camera 4 are both arranged toward the glass 1, for collecting image information above the glass 1. In this embodiment, the glass 1 is a glass arranged above the display screen to play a protective role.

[0029] In this embodiment, the first camera 3 and the second camera 4 are arranged corresponding to the same side of the glass 1, preferably at two corner positions of the same side of the glass 1, so the present invention is defined as a single-sided human-computer interactive touch device.

[0030] In this embodiment, a light guide bar 2 is fixedly mounted on the side of the glass 1, and a first camera 3 and a second camera 4 are mounted at either end of the light guide bar 2. In this embodiment, the touch device further includes a light-emitting LED lamp 5, which can be used to provide supplemental lighting for the display area of ​​the glass 1 (i.e., area AA in the figure). Preferably, the light-emitting LED lamp 5 is positioned corresponding to the light guide bar 2, so that light emitted by the light-emitting LED lamp 5 can enter the light guide bar 2. After reflection and refraction within the light guide bar 2, the light is more evenly illuminated toward the display area of ​​the glass 1 (i.e., area AA in the figure), providing supplemental lighting. In specific implementations, the light-emitting LED lamp 5 can also be positioned directly within the light guide bar 2, so that light emitted by the light-emitting LED lamp 5 directly illuminates the light guide bar 2. One or more light-emitting LED lamps 5 may be provided. When the luminous LED light 5 is set at both ends of the light guide bar 2, it will interfere with the first camera 3 and the second camera 4. When the luminous LED light 5 and the first camera 3 and the second camera 4 are set at the same position, when the luminous LED light 5 is set below and the first camera 3 and the second camera 4 are set above the luminous LED light 5, a stacking effect is produced, that is, they will not affect each other. The light emitted by the luminous LED light 5 can directly illuminate the light guide bar 2. The height of the first camera 3 and the second camera 4 is located above the light guide bar 2. The light guide bar 2 will not block the first camera 3 and the second camera 4 from collecting touch information of the display area of ​​the glass 1 (that is, the AA area in the figure).

[0031] During use of the present invention, when a touch object 6 enters the display area of ​​the glass 1 (i.e., area AA in the figure), the first camera 3 and the second camera 4 respectively capture information about the touch object 6. Since the relative positions of the first camera 3 and the second camera 4 are fixed, that is, the connection line between the first camera 3 and the second camera 4 is fixed, when the first camera 3 and the second camera 4 capture information about the touch object 6, the connection line between the touch object 6 and the first camera 3 and the second camera 4 can also be calculated from the image information. Therefore, the angle between the connection line between the touch object 6 and the first camera 3 and the second camera 4 and the connection line between the first camera 3 and the second camera 4 can also be calculated. Using a trigonometric positioning algorithm, the coordinate information of the touch object 6 can be calculated and output, thereby obtaining the touch point information.

[0032] The light guide bar 2 , together with the light-emitting LED light 5 , the first camera 3 and the second camera 4 , are preferably installed above the glass 1 . In specific implementation, they can also be installed on the left or right side of the glass 1 .

[0033] The unilateral touch device of the present invention simplifies the existing traditional touch installation and production process, improves the user experience, and the user can realize the human-computer interaction function by simply installing the touch device on either side.

[0034] This single-sided touch device utilizes a reflective design, resulting in an extremely thin and narrow design. This design optimizes both the LED light output surface and the camera light input surface, reducing wasted light and lowering the physical touch height, significantly reducing the risk of stray strokes and improving the writing experience. Because it utilizes a single-sided design, it is waterproof whether installed on the top, left, or right side, improving reliability in actual customer use scenarios.
