Next up was Orlando-based company Outhouse Games, which showed off the Oculus VR headset. Normally, Outhouse Games develops mobile-based game applications, but after the creation of the virtual reality headset, the company started looking for ways to develop games for the Oculus.

Mind-controlled computing is a new field. So new, that in 2009, Emotiv Systems open-sourced their brainwave-reading headset to developers and researchers to help drive innovation. Musician Richard Warp responded to the challenge. Warp is a composer, married to a neuroscientist, who believes in creating music with your mind. Using a neuroheadset (his is an Emotiv EPOC, but there are plenty of brain-computer interfaces (BCI) on the market these days for under $100), he built a generative music system that responds to the brain signal.

Coleman and his team are developing wireless flexible electronics one can apply on the forehead just like temporary tattoos to read brain activity. "We want something we can use in the coffee shop to have fun," Coleman says. The devices are less than 100 microns thick, the average diameter of a human hair. They consist of circuitry embedded in a layer or rubbery polyester that allow them to stretch, bend and wrinkle. They are barely visible when placed on skin, making them easy to conceal from others.
