With early personal computers, the only way to navigate the computer screen was by keyboard input. While a person could get pretty good at games like Tetris and Space Invaders with only the arrow keys and space bar for input, we would probably admit that the computer mouse was a big improvement. Once the computer could be operated with a range of motion device, it became easy to navigate and select items.
Who Needs Touch Screen Technology?
Early touch screens were used for leaning applications. Young children who lacked the coordination to operate a mouse or keyboard could easily touch an object on the screen. Touch screens were also instrumental in special education classrooms where students had visual, motor, or cognitive deficits. For students of all ages, touch screens for those with learning problems were – are – useful tools.
Who Else Uses Them?
Picture yourself at the counter of a fast food restaurant, such as McDonalds or Jack in the Box. As you place your order, you see the counter clerk touching a computer screen. If you can sneak a peek, you’ll see pictures of various sandwiches, side orders, beverages, etc., on squares shown on the monitor. By touching the appropriate squares, the clerk sends your request to the kitchen, where the order will be filled. We’ll soon submit the orders ourselves in all sorts of restaurants via use of customer touch screens.
Regarding the uses for touch screen computer monitors, the applications mentioned here barely scratch the surface. The technology has grown so quickly, touch screens are now used by virtually every industry. The availability of touch screens ensure that you will soon be using one at home, if you aren’t already.
