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, reports Mashable.
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.
The team behind project Eidos - Tim Bouckley, Millie Clive-Smith, Mi Eun Kim and Yuta Sugawara - see many possible applications of this technology.
For example, one could use the visual mask it to analyze movement and technique in sports. In another example, concert-goers could use the hearing mask to focus on a certain performer at a concert.
