Disney develops method to feel textures on a touchscreen
Disney has developed something that might change the world of touchscreen devices forever. Imagine sliding your fingers down a glass touchscreen and feeling, oh, sandpaper. What those lab rats mice at Disney have come up is a method that allows a touchscreen to fool your fingers into believing that the tactile feedback you are experiencing is real. Here comes the science part. Disney found that by using using electrovibration it could create electrostatic forces that fool your finger into believing that the friction you are feeling is a pile of broken glass, or whatever is on the screen.

Disney's team uses an algorithm to create the different feelings. There are three different parts to the algorithm which Disney explains like this: "1) Calculate the gradient of the virtual surface we want to render, 2) Determine the “dot product” of the gradient of the virtual surface and velocity of the sliding finger, and 3) Map the dot-product to the voltage using the psychophysical relationship." Well, of course it sounds simple when they say it! The algorithm is based on the discovery that when our finger feels a bump when we slide over one, it is because friction compresses and stretches the skin on that finger.

There is a whole paper that supposedly proves that this works and we can tell you that it wasn't written by Goofy! Obviously it is still early days for this kind of technology, but eventually this could lead to some interesting things down the road that you might consider kind of cool.

Imagine yourself sliding your finger on a vigina photo ! something that might change the world of touchscreen devices forever. Amen to this !!

Innovation in porn is here !

Porn isn't, wasn't and is never going to be even associated with innovation.

The entire act in essence is reprehensible, backward, and very primitive.

Good luck looking for "innovation" there.

This is absurdly cool, but I bet its going on the pile of "tech that should, but never does reach our phones".

It will, maybe not now but certainly before the end of the decade trust me. Senseg demoed this technology two years ago and they said something was going into production the next year in 2012 rumoured for the IPad 3 but we all know that turned out to be a lie.

This is a potential technology breakthrough that would be coveted by the masses providing any manufacturer of phones and tablets instant success by offering a unique feature that people will actual desire.... and its coming from Disney. Samsung and Apple better get busy trying to steal some of that engineering talent.

They need to use this technology for touch screen keyboards, so I can feel the key I am about to press before I press it. Also, include pressure sensitivity, so I can touch the screen without registering a key press on the keyboard. Once my finger feels it is about to press the right key, then apply pressure and have the touch screen keyboard then register the key press.

innovation at its best. now we will move beyond the glass and back to feel. I want flip phones again.
