Swipe, pinch, zoom & tab – All you want to know about Touchscreen Technology

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.
