Researchers Developed Mind-Reading Device to Send Text with Brain

Mind-reading device can answer questions in your head by picking up signals sent from your brain when user think about saying something
Team of researchers from MIT developed a device, which can measure subvocalization signals of humans. Conventionally, most of the brain-computer interface devices use EEG to detect brain activity. The MIT headset, called AlterEgo, detects subvocalization signals, processes them through a neural network, which translates the signals into words and feeds the words back to user via bone-conduction audio.

The team used the headset to navigate a Roku box, report the time, and cheat at chess, but the implications are far-reaching and very exciting. “The digital interface that we currently have with our devices is very unnatural, and while a vocal interaction is better, not everyone is going to feel happy speaking out loud to their phone while out and about,” said one of the researcher involved in study.

Current EEG headset operated devices enable people to type by giving user control of a cursor, which is a slow and arduous process. The ability to give commands and type at the rate of thought could be a vast leap forward. Integration of this device in warbles such as pair of smart glasses, would allow user to control the device using just mind. The paper describing study is recently published by MIT. However, it is not disclosed by the company if AlterEgo is will be available commercially. This technology offers new avenues in next stage of brain-computer interface.
