Scalextric-style slot cars that can be controlled with your brain — going faster the harder you concentrate — were demonstrated at the Consumer Electronics Show.

Attendees at the technology event — held in Las Vegas in the US — wore headbands based on medical brain-scanning tech to race model cars about a track.

Also on display was the final version of an artificial-intelligence-powered prosthetic hand for amputees that works with both brain waves and muscle signals.

Scalextric-style slot cars that can be controlled with your brain — going faster the harder you concentrate — were demonstrated at the Consumer Electronics Show this year

BRAINCO'S FOCUS1 HEADBAND SPECS Weight: 95 grams Battery Life: Up to 4 hours Battery Capacity: 400 mAh Charge time: 1–1.5 hours Electrodes: Made of hydrogel Advertisement

The company behind the mind-reading technology is Massachussets-based firm BrainCo, which grew out of Harvard University's Innovation Lab.

The slot car setup worked by using the Focus1 headbands to non-invasively measure participant's brain activity and transfer this to a paired model car on the racetrack.

The technology is based on conventional electroencephalograms.

These are medical scanning devices which use tiny sensors applied to the scalp to pick up on the electric signals generated as brain cells communicate with each other.

The more each 'racer' concentrated, the faster their car would go.

The device 'translates your brainwaves into electronic signals,' the Boston-based firm's Zenchuan Lei has explained.

The demonstration of the Focus1 headband technology appears to have gone down well with attendees at the Consumer Electronics Show this year.

'Is this a #jedimindtrick or modern #engineering? Control a toy race car with your mind using the BrainCo FocusFun,' joked researcher Ashton Farmer on Twitter.

BrainCo's exhibit this year was a step up from their similar demonstration at the Consumer Electronics Show of 2019, using a racetrack setup with four lanes rather than the previous year's two.

BrainCo has other applications in mind for its brain-scanning tech, however.

Also on display at the Consumer Electronics Show this year was the final version of an artificial-intelligence-powered prosthetic hand for amputees that works with both brain waves and muscle signals.

The firm has also previously suggested that the headbands could be used to control smart devices around the home, scan for disease and even — controversially — monitor the brain activity of schoolchildren to track their attention in class.
