MAN CAN NOW CONTROL TURTLE'S MIND.
Scientists have developed a new Avtar-style technology that allows a human controller to manoeuvre a turtle's path just using their thoughts. In the 2009 blockbuster 'Avtar', a human controls the body of an Alien. Researchers are developing 'brain-computer interfaces' (BCIs) following recent advances in electronics and computing. These technologies can 'read' and use human thought to control machines. Studies have demonstrated the possibility of combining a BCI with a device that transmits information from a computer to a brain, or a 'computer-to-brain interface' (CBI). The combination of these devices may be used to establish a functional link between the brains of different species. Researchers from the Korea Advanced Institute of Science and Technology in South Korea have developed a human-turtle interaction system in which a signal originating from a human brain can affect where a turtle moves.
The entire human-turtle setup includes a head-mounted display (HMD) combined with a BCI. The human operator wears the BCI-HMD system, while the turtle has a 'cyborg system' - consisting of a camera, a Wi-Fi transmitter, a computer control module and a battery - all mounted on the turtle's upper shell. The human operator receives images from the camera. The human provides thought commands that are recognised by the wearable BCI system as electro-encephalography (EEG) signals. The BCI can distinguish between three mental states: left, right and idle. The left and right commands activate the turtle's stimulation device via Wi-Fi, turning it to that it obstructs the turtle's view.
This invokes its natural instinct to move towards light and change its direction. Finally, the human acquires updated visual feedback from the camera mounted on the shell and in this way continues to remotely navigate the turtle's route.
