We recently came across a wearable that is capable of reading people's minds. Experimenting with new form factors and interfaces, the Dr Xavier type of device allows the wearer to control devices and ask queries without speaking. Called AlterEgo, the wearable tech device, designed by researchers at MIT's Media Lab, can transcribe words that wearers verbalise internally. Simply put, the invention uses electrodes attached to the skin to capture words inside the wearer's head. "Our idea was: could we have a computing platform that's more internal, that melds human and machine in some ways, and that feels like an internal extension of our cognition?" said Arnav Kapur, who led the Intelligence Augmentation research of the Silent Computer Interface system at MIT's Media Lab.
