Senseg turns touch screens into Feel Screens. With Senseg touch screens come alive with textures and edges that users can feel. Using Senseg technology, makers of tablet computers, smart phones, and any touch interface device can deliver revolutionary user experiences with high fidelity tactile sensations
This is how it works:
By passing an ultra-low electrical current into the insulated electrode, Senseg’s Tixel, the proprietary charge driver can create a small attractive force to finger skin. By modulating this attractive force a variety of sensations can be generated, from textured surfaces and edges to vibrations and more.
