Gesture tracking is the future of interaction, so how to solve tactile feedback

    The rise of smartphones has allowed us to interact with machines by tapping on touchscreens. So what other ways of interaction will humans develop behind this small piece of glass? Will we all interact with devices through voice? Or will we wear augmented reality glasses and receive the information we need all day long? Or will touch interaction be made so good that we will never really replace it?

Touch has been dominant for a long time

    For decades, we have been using our hands to operate and view various information. Whether we admit it or not, our brains are constantly processing the information we get and feeding it back to our hands, telling them how to respond. As touch screens become more and more popular, many devices no longer need to be connected to a physical keyboard or mouse, but we have no way to get touch feedback. When we use mobile phones and tablets, we need to focus on the device, because when we look away and click the screen, we can't know whether we clicked correctly.

Augmented reality is a possibility

    The closest thing to replacing touch is augmented reality. The idea of ​​overlaying information on things is appealing to many people, but today, its application is still clumsy. Google Glass is too expensive, its application areas and methods are very limited, and a smaller version is still a luxury. If touch is removed from Google Glass, it will cause other problems, because if voice control or eye tracking technology is used, both of them still have their own unique problems as far as current technology is concerned.

Gesture tracking + haptic feedback

    Maybe there is a way to merge all these technologies together. In the future, it will be possible to use implants or nanotechnology to let us feel things that are not there. Displays will be able to hover in the air in front of you, and the next breakthrough will be to develop a gesture control system that provides tactile feedback, so that you can feel the feedback you get when you press it. We still have a long way to go to make this whole system work properly.

    As mentioned above, in the future people may use implants or nanotechnology to allow us to get tactile feedback when using gestures, but this is not the best solution. After all, compared to the mouse and keyboard, although gestures plus tactile feedback are very cool during use, the way to obtain this tactile feedback is a bit complicated. Does everyone need to go to the hospital for implant surgery or injections to get tactile feedback? And what kind of diverse feedback can implants in the body bring us also needs the attention of researchers. Just simple vibration feedback is not enough for people to pay such a high price for it.

    Currently, the only tactile feedback devices that are practical and easy for people to use are gloves or devices worn on the user's hands.
