Disney is not normally at the forefront of technological advancements - unless we're talking about theme parks - but its new technique for "feeling" touch screens sounds pretty magical.
The company's Pittsburgh researchers, including one Dr. Ali Israr, have developed an algorithm that generates "electro-vibration" when a touchscreen user's fingers touch certain points on the display.
When users' fingers land on something that should feel textured, the device emits vibrations, creating the illusion of an object with actual, physical texture.
And because many touchscreen devices already have vibrating feedback motors the system should be easy to implement, according to the researchers.
The Disney touchscreen technique simulates what it really feels like to touch textured objects, like pineapples, fossils and interactive maps, by recreating that feeling using small vibrations.
Apparently its algorithm creates vibrations that are pretty close to what actually happens when you touch something.
"Our brain perceives the 3D bump on a surface mostly from information that it receives via skin stretching," said Ivan Poupyrev, head of the interaction research group that developed the technology.
The vibrations reportedly stretch the skin of a user's fingertips just enough to make it seem like they're really feeling something.
When it's described like that, it seems obvious - haptic feedback is important, after all. That's why your phone vibrates when you type a letter.
The system is also more versatile than other haptic feedback touchscreen gimmicks, like the Tactus microfluid tech touted last year, because it can "tune tactile effects to a specific visual artifact on the fly," said Israr.
- Are haptic touchscreens the future, or has the future of touchscreens already been revealed to be bigger, cheaper, and bendier?
