Nokia has been working on a very promising technology, called Haptikos, and it is now coming to fruition after 10 years in the making. The new technology promises a true tactile response for touchscreen text input methods. Though basic vibration methods are currently in place to provide a form of haptic response, Nokia's efforts will literally relay the sensation and sound of a physical keyboard click—right beneath your finger. The Senior Program Manager at Nokia's research lab, Roope Takala, explained how the engineers were able to accomplish the seemingly impossible:
"The basic technology is not that difficult...we inserted two small piezo sensor pads under the screen and engineered in a 0.1mm movement in the screen itself. What's taken the time has been fine tuning the movement and response to mimic exactly the sensation of pressing a real key."
"...it was hard to remember that you were using a touchscreen keyboard."
