Description
Technical Field
[0001] This invention relates to the field of wireless touch technology, and more particularly to an interactive wireless touch method for display devices. Background Technology
[0002] Existing touch screen all-in-one machines consist of a display section and a touch section. During daily use, the following issues arise: 1. Users must stand directly in front of the machine, which can obstruct the view; 2. The display screen itself has internal backlighting that generates heat, which can become excessive in high-temperature environments, leading to overheating and discomfort when writing on it; 3. When the screen is large, it's difficult to click or access the upper portion, rendering it unusable; 4. Using the display screen at close range can significantly impact eyesight and also emits radiation that can be harmful. Summary of the Invention
[0003] This invention proposes an interactive wireless touch control method for display devices to address the aforementioned shortcomings in the prior art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An interactive wireless touch method for a display device includes the following steps:
[0006] S1. Software Installation: First, install writing software compatible with the writing device on the display device controller;
[0007] S2. Wireless receiver installation: Then connect the wireless receiver to the display device that needs to be connected. The wireless receiver will be powered on and started when connected.
[0008] S3. Wireless connection between writing device and display device: When the writing device is turned on, the writing device controller starts operating. The writing device controller controls the operation of the touch module and the wireless transmitter. After the wireless transmitter starts operating, it automatically connects with the wireless receiver and calculates the writing position and coordinates on the writing device. After the writing device controller starts operating, it will transmit the electricity from the polymer battery to the touch module and the wireless transmitter, thereby enabling both to start operating. The infrared light net is emitted from one side of the writing device to the other side, covering the entire writing position of the writing device. The writing device controller performs basic coordinate editing on the writing position, and the coordinate position of the object movement later is based on the basic coordinates.
[0009] S4. Judgment: The writing and erasing judgment is divided into two methods: infrared touch and capacitive touch. Infrared touch method: When an object passes through the infrared light grid, it will block the infrared light. The touch module transmits the blocking data to the writing device controller. The writing device controller calculates the XY coordinate data and the object blocking area based on the blocking data. When the blocking area is within the writing pen area, the writing device controller judges it as writing mode. If it is greater than the writing pen area, it is considered as erasing mode. The blocking area range value is set by the user according to the size of their own writing pen and eraser for accurate recognition. Capacitive touch method: When the entire writing surface is covered with a capacitive film, when a human body or conductive body comes into contact with the capacitive film, a conductive phenomenon will occur. The IC calculates the coordinate position of the conductive area. If the conductive area is within the writing pen area, the writing device controller judges it as writing mode. If the conductive area is greater than the writing pen area, it is judged as erasing mode.
[0010] S5. After determining that the writing state has been entered, when the object moves at the writing position, it transmits occlusion or conductive data to the writing device controller. The writing device controller calculates the XY coordinate data and the area of the object based on the occlusion or conductive data, and continuously sends the coordinate data and area data to the wireless transmitter. After receiving the continuously transmitted coordinate data and area data, the wireless transmitter continuously transmits the coordinate data and area data to the wireless receiver by transmitting wireless signal waves. The wireless receiver transmits the continuous coordinate data and area data to the display device controller. The display device controller transmits the continuously input coordinate data and area data to the writing software. The writing software recreates the writing trajectory on the writing device according to the coordinate data and area data and displays it on the screen of the display device. The writing trajectory forms a line through the coordinate points, achieving the purpose of writing text.
[0011] S6. Wireless Erasure: After determining the erasure state, when the object moves on the writing position, it transmits data to the writing device controller. The writing device controller calculates the XY coordinate data and the area of the object based on the occlusion data, and continuously sends the coordinate data and area data to the wireless transmitter. After receiving the continuously transmitted coordinate data and area data, the wireless transmitter continuously transmits the coordinate data and area data wirelessly to the wireless receiver by transmitting wireless signal waves. The wireless receiver continuously transmits the coordinate data and area data to the display device controller. The display device controller transmits the continuously input coordinate data and area data to the writing software. The writing software reconstructs the movement trajectory on the writing device according to the coordinate data and area data and displays the writing trajectory on the screen of the display device for erasure. The erasure trajectory forms a line through the coordinate points, achieving the purpose of text erasure.
[0012] Furthermore, the writing position is a writing board, the writing device controller is connected to the writing board, the writing device is installed on the front side of the writing device, and the wireless transmitter is installed on the writing device controller.
[0013] Furthermore, the writing device contains a polymer battery, which is electrically connected to the writing device controller.
[0014] Furthermore, the writing device also includes a switching function key, which is installed on the front side of the writing board, and the switching function key includes, but is not limited to, a pen color switching key.
[0015] Furthermore, the writing device controller and the wireless transmitter are connected via USB or TPCY-C, and data transmission between them is also transmitted via USB or TPCY-C.
[0016] Furthermore, the wireless receiver and the display device are connected via USB, and data is transmitted between them via USB.
[0017] Furthermore, the area data refers to the area blocked by the object after the infrared light net is emitted from one side. A small blocked area indicates a writing state, while a large blocked area indicates an erasing state. The thickness of the movement trajectory is determined based on the area data. Alternatively, the entire surface of the writing device may be a capacitive film. When a conductive body comes into contact with the device, a small conductive area indicates a writing state, while a large conductive area indicates an erasing state. The thickness of the movement trajectory is determined based on the conductive area data.
[0018] Furthermore, an adjustable support frame is fixed to the bottom of the writing device, and casters are fixed to the bottom of the support frame.
[0019] Compared with existing technologies, the beneficial effects of this invention are:
[0020] This invention solves the problems of human body obstructing the screen, screen heat causing user discomfort, poor screen utilization, impact on user vision, and radiation by writing wirelessly on a writing board and displaying it on all display devices. Moreover, this invention reduces the distance and range of motion required by the user during the writing process, making it more effortless and greatly improving the convenience of using large screens.
