Several years ago, displays were only made to display something. But later, we started to interact with them. Touch screens were built and now, in most of the smart phones and tablets, they replaced the old buttons. No buttons but only touch!
But now, scientists are trying to bring physical buttons to touch screens! Buttons which we can actually touch and feel. But they are not just simple buttons. The Tactus team is trying to make them dynamic. That means they’ll pop-up only when needed and they’ll take any shape and size according to the content displayed on the screen.
Currently, its only an experiment. Check out the YouTube video for more details. They say it will be ready by 2013. So, will it revolutionize the touch screens? What do you think?
