Creativity has no limits, and it is fun to marvel at all the amazing technical innovations that continue to pour out of the minds of engineers. One case in point is the following idea from the Japanese company, KDDI. They are working on a touchscreen device that gives the sensation that you are actually pushing physical buttons. Here's a quick quote from the AndroidPolice article talking about this interesting new tech,From the looks of things, it will be a little while before we see this start to show up in phones. This may not be an earth-shattering idea, but sometimes the little things turn out very useful.This new technology is made possible by combining a pressure sensitive touchscreen with haptic vibrations, which results in the sensation that you’ve actually moved something. One really nice thing about this is that this advancement doesn’t add any addition bulk to the device – the touchscreen can be created in the same size and thickness of current devices.
