Imagine you’re sitting on the sofa, but you forgot to pick up the TV remote, and your smart speaker isn’t listening to your request. Wouldn’t it be wonderful if your sofa’s armrest could act as a remote? That could be possible with MIT’s new sprayable sensor technology. Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have built a system called SprayableTech, that lets you create interactive surfaces.
