A one-size-fits-all noninvasive brain-computer interface (BCI) enables users to play computer games through mind-reading.
Brain-computer interfaces are a new technology that allows users to control computers with their minds.
The concept of brain-computer interfaces is simple: use technology to help “read” a person’s mind and execute commands to manage external computing devices. The execution is much more challenging. BCIs require the capturing of brain activity by recordings and figuring out a person’s intended action. The brain activity recording device can be an invasive implant that requires surgery to be placed in the appropriate brain areas or a noninvasive, such as an electroencephalography .
What sets this study apart is that The University of Texas at Austin researchers have developed an innovative method to produce a brain-computer interface that does not require calibration using inter-subject transfer learning and a special framework that they developed. For this study, participants wore a noninvasive cap with electrodes that measure electrical brain signals that a decoder translates into commands. The researchers evaluated their framework with 18 healthy study participants on two tasks: a simple game of balancing a digital bar and the Cybathlon car racing game. An initial decoder to translate brain activity into computing commands was developed from data collected from a single user who performed the bar task only, not the car racing game.
