Meet the EEGSmart Touch: a smart wearable device that reads your brainwaves and translates them into commands, allowing you to control your drones and interact with other devices. It has a lightweight hardware that reads from 8 regions of your brain. The developers are planning to release a SDK and API for the device.
Touch could prove useful for virtual reality gaming, meditation, controlling drone, and interacting with smart homes. You can find out more about it on Indiegogo.
