You can use a touchscreen monitor to control your screen and your apps with your finger. That's useful to give a presentation, to let your customer look up a product in your self-service warehouse, or for a cash register system. Touchscreen monitors are also useful for the home or office. Scroll through a web page with your fingers or zoom in on a photo. There are touchscreen monitors available that you can adjust in height. This way, you place the screen at a comfortable working height and your fingers can easily reach it.
