Infrared touch screen overlays (IRTs) are often installed as add-ons to existing displays or integrated into new displays to make them touch-sensitive. The IRT framework differs from other types of touch screen frameworks, such as capacitive or resistive, in that it does not rely on physical touch; instead, it employs infrared emitters and receivers to detect interruptions in infrared light beams that occur when a touch occurs.
Here are the steps to connect an Infrared touch screen overlay:
Step 1: Verify the System Requirements
Before you begin setting up the IRT, you should ensure that your system complies with the framework requirements. The IRTs usually require COM or USB ports and will operate on a variety of operating systems, including Windows, iOS, Linux, and Android.
Step 2: Determine the Overlay’s Electrical Connections
When acquiring an IRT, make sure you choose one that is consistent with the display you want to transform into a touch screen. The IRT will connect to the display through either an HDMI or VGA port. The IRT’s electrical link will be installed behind the display, and you should follow the overlay manual’s wiring guidelines for the specific IRT that you have purchased.
Step 3: Plug in the USB Cable
An IRT’s USB cable connection enables it to connect with your computer or display’s USB port and automatically install the necessary drivers and software. Once the software is installed, the touch screen should be calibrated to ensure correct touch detection.
Step 4: Calibrate the Touch Screen
After connecting and installing the IRT software, you will need to calibrate your touch screen to ensure that touches detect correctly. Many IRT vendors will provide a calibration program with the overlay device, or the vendor may offer an online calibration tool to assist you in calibrating your touch screen.
Step 5: Test the Touch Screen
After completing calibration, the touch screen is ready to use. You can now do a test run by touching various points on the touch screen to verify if it responds appropriately.
In conclusion, the infrared touch screen overlay connectivity involves verifying the system requirements, connecting the overlay’s electrical connections, plugging in the USB cable, calibrating the touch screen, and testing it.
