If actually interacting with your mobile seems like too much hassle at times, researchers at Massachusetts Institute of Technology and Microsoft are working on a way to turn your body into a controller.
The system, known as DuoSkin, turns a temporary tattoo into a remote control for your smartphone. You can interact with your phone by swiping on your tattoo, as you would your phone as normal. The researchers say that DuoSkin is comfortable and light on the skin.
It’s also said that these tattoos can respond to changes in a body’s temperature, lighting up or changing colour when someone gets warmer. It’s also mentioned that one tattoo could show off your mood or emotion, which could be quite useful!
You can get a walkthrough of the system in the video below; it’s an interesting watch.
