Here are 4 fun facts about touch screens you probably didn't know.
1. Touch screens date back to the 1960's
Touch screens seem like a relatively new technology that entered mainstream use only a few years ago. But did you know touch screens have been around for decades?
The first signs of touch screen life can be found in the early 1960's when E.A. Johnson invented the first finger-driven touch screen. He published his invention in an article not realizing that over 50 years later we wouldn't be able to live without it.
2. We can't imagine life without touch screens
It's hard to find an industry where touch screens are not a standard. Touch screens are literally everywhere. From the workplace to stores, restaurants, schools, hospitals and airplanes.
It's almost like we are expecting them to be there. Have you not caught yourself in front of display and swiping the screen with your finger and nothing happened?
We are so used to touch screen displays that our intuition tells us how to use them. Experts don't expect this touch screen trend will go away any time soon. So lets look forward to more touch screen applications that make our lives easier!
3. Touch screens measure our electrical charge
Yes, they do! Capacitive touch screens, one of the most used touch screen technologies used today, work by measuring the electrical charge in the toucher's body.
Actually, they rely on the electricity conducting qualities of the human body to work.
When you touch the surface of a capacitive touch screen it measure your electrical charge. You are in fact interrupting the electrical flow that runs along an X and Y grid on the touch screen. This change in flow triggers the input to be registered.
4. Touch screens are extremely intuitive
Put a tablet in front of a 2 year old and they quickly figure out how to work the screen and do what they want it to do. Amazing isn't it?
There is no special skill needed to work a touch screen. Where operating a regular computer mouse could take a bit of practice for new users, touch screens just require the ability to point and touch.
Multi touch technology is another innovative technology that has quickly become embedded into our lives. Small unclear image? Lets just 'pinch and zoom' to get a better view! It's an action we intuitively take in an attempt to see better.
Of course all the smartphones and tablets around us have had a great impact on the adaption of touch screens in our every day lives. But the intuitive qualities of a touch screen can also be credited for its success.
