Haptics (touch) technology has been around for a while (think about how you can "feel" the buttons vibrate when you tap on your smartphone), but now is being developed with more real time control and feedback between fingertip and touchscreen. Companies like Tanvas are finding new uses for this technology. Tanvas Touch allows the user to "feel" different textures - such as grainy, silky, wavy and more - on a smart screen. It has also been used to simulate different fabrics, wood, stone and grass. Users have reacted differently to this - with some being very impressed and others "not feeling it" as much. Haptics technology could have a lot of really neat applications - it could allow users to "feel" fabrics before they purchase clothing online, it could be used in immersion gaming, and it could also be used to help the visually impaired when they use smart technology. It will be interesting to see how this technology develops over time and what new applications people create for it.
