It’s a device that would be more at home on the set of a Star Wars movie than the streets of Britain. But an iPhone application has been developed that can read minds. The XWave allows users to control on-screen objects with their minds as well as train their brains to control attention spans and relaxation levels. The device – that could confuse Luke Skywalker himself – is the latest in the field of emerging mind-controlled games and devices and works via a headset strapped around the user’s forehead, plugging into the iPhone jack. A state-of-the-art sensor within the device can then read the user’s brainwaves through the skull, converting them into digital signals before displaying them in various colours on the iPhone screen.
