Finnish company Senseg has developed a haptic touch technology called Senseg e-Sense which produces feedback on touchscreens using a tiny electrical charge and non-mechanical vibrations. The idea is for the charge to be sent through a film attached to the screen, which vibrates in different ways according to the on-screen stimulus. The result is a tactile response as you move around the screen elements.
It’s clever stuff and has now been picked up by Toshiba, which is about to release a software development pack for developers to start coming up with applications.
Senseg E-Sense technology is a quiet, safe, and versatile solution for adding touch feedback to touch input. E-Sense creates a modulated attraction force (Coulomb force) between finger tissue and E-Sense surface. The accurately controlled attraction force generates pleasant vibration-like touch sensations that improve the user experience of touch interfaces.
