Wheelchair controlled by facial expressions to hit the market within 2 years

Brazilian researchers have developed a wheelchair that can be controlled through small facial, head or iris movements. The team at Faculdade de Engenharia Elétrica e de Computação da Universidade Estadual de Campinas (FEEC/Unicamp) says the technology could help people with cerebral palsy, those who have suffered a stroke or live with amyotrophic lateral sclerosis and other conditions that prevent precise hand movements.Read More


Brain-controlled drone racing truly is a battle of wills

Drone technology is becoming quite a popular testbed for neuroscientists seeking to put brain-computer interfaces through their paces. Numerous research projects have already impressed us with drones controlled by nothing other than the power of thought, but for some, merely flying the things is already a tad passé. The Brain Drone Race takes this technology and gives it an edge, imploring pensive pilots to will their drones across the finish line ahead of the competition.Read More


Mobile EEG cap to enable brainwave monitoring on the go

Like many scientists around the world, researchers working out of UC San Diego have high hopes for how our brainwaves might one day be used to control devices, tackle neurological disorders and everything in between. But for that to happen, the devices used to monitor them not only have to be highly advanced, but comfortable and practical to wear on our heads in everyday environments. The team has now taken a promising step towards such a future, unveiling what it says to be a first-of-its-kind EEG headset that will take brain monitoring out of the lab and into homes, cars and offices.

Flashing LEDs facilitate brain-controlled exoskeleton

Lower limb exoskeletons show great promise in helping those who have lost the use of their legs to walk again. However, if a person has been rendered quadriplegic, any hand controls in such a device are essentially useless. To help address this and other whole-of-body disabilities, scientists working at Korea University (KU) and Technische Universität Berlin (TU Berlin), have created a hands-free brain-to-computer interface to control a lower limb exoskeleton by specifically decoding signals from the wearer’s brain.Read More


Connected brains share control of virtual limbs and predict the weather

If the thought of using a person's brainwaves to control a machine isn't quite enough to make the mind boggle, then mixing signals from multiple brains for the same purpose might just do the job. This far-fetched field of neuroscience is edging ever closer to real-world technology, with a number of recent research efforts achieving significant advances, with mind-controlled drone flight just one example. The latest step forward in this area sees the brains of separate animals hooked up and their combined motor and sensory information used for things like controlling a virtual arm, pattern recognition and even predicting the weather.Read More


Quadriplegic successfully uses mind-controlled robotic arm

In 2012, a quadriplegic woman managed to move a robotic arm, using only her thoughts, to a level of proficiency that allowed her to eat a chocolate bar using said arm. The University of Pittsburgh team behind the study didn't stop there, though. By improving the technology in the arm and working more closely with test subject Jan Scheuermann, they have since enabled her to replace the simple pincer grip of before with four new hand shapes – fingers spread, pinch, scoop, and thumb up – that allow for more complicated object manipulation.Read More


"Mind-reading" MindRider bike helmet wants you to have a sweet ride

While many people will tell you that commuting by bicycle is less stressful than driving, the fact remains that it can still be ... well, stressful. While you could try to determine the least-taxing route by jotting down how tense you are in which places, doing so could get pretty complicated. The MindRider, however, is designed to make that process easier. It's a "mind-reading" bike helmet that lets you create so-called mind maps of your travels. Read More

3D-printed EEG headset from OpenBCI is customizable and open-source

When Gizmag wrote about OpenBCI, a brain-computer interface system with open-source software, the company was waiting to announce an EEG headset it claimed would be entirely new. A few days later, the OpenBCI board is fully funded and we’ve seen how the team will implement a customizable and modular 3D-printed headset with open-source availability. The design not only showcases the utility of 3D printing, but more importantly demonstrates the company’s commitment to creating an open community around their product. Read More
