Researchers at the Korea Advanced Institute of Science and Technology have developed a brain-computer interface (BCI) that can control a turtle using human thought.
The interface includes a head-mounted display (HMD) paired with a BCI to immerse the human user in the turtle's environment.
The user wears the BCI-HMD system, while the turtle's upper shell is equipped with a "cyborg system," which consists of a camera, Wi-Fi transceiver, computer control module, and a battery. The human operator receives images from the camera mounted on the turtle, which enables the operator to decide where the turtle should move. The operator provides thought commands that are recognized by the wearable BCI system as electroencephalography signals.
The system can distinguish between three mental states: left, right, and idle.
The researchers say their technology could be used to develop positioning systems, as well as improve augmented and virtual reality systems.
