Wearable tech is all the rage (and probably the next big trend in fashion and style), but this is one fans of “Iron Man” will take notice of: A group of students at the Royal College of Art in London have created two masks that can give you superhuman sight and hearing. The first prototype covers the wearer’s ears, mouth and nose and uses a directional microphone to give him the ability to hear an isolated sound in a noisy environment. For example, you could target a person in a crowd and clearly hear his words without the surrounding noise. The other prototype is worn over one’s eyes. A camera captures video and sends it to a computer, which can apply a set of effects to it in real-time and send it back to the wearer. One can, for example, use it to see movement patterns, similar to the effects of long-exposure photography.
