It seems like touchscreens are on every electronic these days. I wanted to find out the history of touch screens so I went on Google. Touch screens started in a research lab halfway through the 1960’s. The first place they were viewed was in 1972 as a project called PLATO which is a computer learning terminal. The touch screens have become more accustomed to in kiosk systems like on ATM machines; PDA’s where a person uses a stylus to enter information in. The main reason that touch screens are becoming so popular is because of smart phones, PDA’s, portable game consoles, and appliances. The earliest touch screen computer that is known of was the HP-150 in 1983. It was not an actual touch screen but it had infrared transmitters which found any “non-transparent object” that was seen on the screen. By the 1980’s most of the touch screens could only detect one touch at a time and there was a small amount that could detect how hard a person would touch the screen. There have been many touch screen sensors that have been made by many different companies. Currently the producers of touch screens have noticed that the touch screen is a very popular user interface and that is what people desire. I was very surprised and found it interesting that touch screens started many years ago.I think touch screens are an awesome technology and I can’t even imagine what new touch screen technology will be out next.
