Hasta La Gadget!

Plenty of companies are experimenting with thought-reading gadgets, and in the cluttered South Hall here at CES, we came across the folks from InteraXon showing off their Indiegogo-funded “Muse brain-sensing headband.” It measures EEG signals from four forehead sensors and two tucked behind the ears, and sends those brain measurements to other gear via Bluetooth. InteraXon has developed an app suite for mobile devices to showcase the headband’s capabilities, including thought-controlled games and brain tracking, exercise and fitness software for improving cognitive function, memory, attention and for reducing stress. That’ll come bundled with any purchased units, but an SDK is also available for third-party developers to explore other possibilities.

They had a demonstration set up on the show floor, so we thought we’d sit down and take it for a spin. The headband was flexible and surprisingly comfortable, and with a bit of fiddling, we were good to go. One monitor showed brain activity on a couple of complicated graphs, while a scene on a second monitor grew busier as our concentration increased. Watching one graph react to blinking was pretty cool, and once concentration levels reached over 85% on the animated scene, it started to snow. While this obviously isn’t very relevant to any potential applications, it was fun to watch the hardware clearly working as intended. You can check out our shots of the headband in the gallery, or check out the video of us trying it out below. Unfortunately we were only allowed to use it for a limited time — the demonstration was in danger of breaking due to this editors’ massive brain.

While some mind-control technologies may not amount to much more than gimmicks, there’s also plenty of serious research being done in the field — particularly when it comes to artificial limbs. So far, the majority of that work has focused on robotic arms, but a team of researchers from the Veterans Affairs Medical Center in Long Beach, California have now made some progress with a robotic leg prosthesis controlled by EEG signals. As you might expect, things remain a bit limited at this point — not amounting to much more than the ability to start and stop — but the researchers say they’ve been able to achieve a 100 percent response rate with no “false alarms,” and that the results are promising enough to begin tackling additional degrees of freedom like turning and sitting. What’s more, while the system has so far only been tested on able-bodied individuals, the researchers hope that it will eventually be able to aid those with spinal cord injuries and aid in rehabilitation. You can get a quick look at it on video after the break.
