Medical computers with touchscreen technology need to meet stringent medical standards. Completely sealed for easy cleaning and touchable with gloves to perform accurate touch-based inputs in patient records in medical clean rooms like operating theaters are a must. Avoiding additional physical keys on the panel, or extra devices like keyboards, mouse or touchpad is efficient as these can harbor bacteria. A touchscreen can detect the presence and location of a touch within the display area, usually one or more fingers or a stylus. The touchscreen enables the user to interact with what is displayed without using an additional keyboard or mouse. Touchscreens are widely integrated in gaming consoles, all-in-one computers, tablets, navigation devices, smartphones, ATM devices and information kiosks. There is a variety of touch technologies that offer different methodologies of sensing the touch. All technologies are related to the X / Y coordinates of the touch sensitive area. The way how to sense the touch point is explained in the next paragraphs.
