A touchscreen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with one or more fingers. The user can use the touchscreen to react to what is displayed and to control how it is displayed (ex: zoom).
This type of technology has become very popular the last few years and is practically the norm. The convenience of tablets has taken over and touchscreen technology plays a huge role. Aside from that, they are now a standard in the medical field, banks and kiosks of all kinds.
Development
At first, touchscreens only worked with a “one-finger” at a time sensor. We now know how far they have come. Multiple users can interact simultaneously thanks to the evolving technology. Technology has improved so much that the marginal cost of touchscreen technology is practically absorbed into the products that function by it and cost is nearly eliminated.
The fact that touchscreens have become so reliable only makes them that much more convenient
Tools
Since fingerprints can be an issue with touchscreens (especially phones), materials with optical coatings can be used to minimize them. Stylus tips of all sizes are available at any price point. Installing a matte-finish anti-glare screen protector (which creates a somewhat roughened surface protected from smudges) is another option.
