Which of the following is an advantage of infra-red optical touch screens?

Infra-red optical touch screens utilize a grid of infrared beams across the screen surface, allowing them to detect touch without the need for a specific type of input device. This technology is advantageous because it enables the use of both bare and gloved fingers for input, making it highly versatile in various environments, such as industrial or outdoor settings, where users may need to wear gloves for safety or comfort. This flexibility enhances user accessibility and convenience, as they do not have to rely on a stylus or other special tools to interact with the screen. The ability to use different types of hands or tools without compromising functionality is a significant benefit of this technology.
