Portable EEG devices have come a long way in recent years. From their humble beginnings as large, wire-studded contraptions that cost upwards of $10,000, they have now reached the point where they are small, portable, and affordable. What’s more, they are capable of not only reading brainwaves and interpreting brain activity, but turning that activity into real-time commands and controls.
Once such device is the Emotiv Insight, a neuroheadset that is being created with the help of a Kickstarter campaign and is now available for preorder. Designed by the same company that produced the EPOC, an earlier brain-computer interface (BCI) that was released in 2010, the Insight offers many improvements. Unlike its bulky predecessor, the new model is sleeker, lighter, uses five sensors instead of the EPOC’s fourteen and can be linked to your smartphone.
In addition, the Insight uses a new type of hydrophilic polymer sensor that absorbs moisture from the environment. Whereas the EPOC’s sensors required that the user first apply saline solution to their scalp, no extra applied moisture is necessary with this latest model. This is a boon for people who plan on using it repeatedly and don’t want to moisten their head with goo every time to do it.
The purpose behind the Insight and EPOC headsets is quite simple. According to Tan Le, the founder of Emotiv, the company’s long term aim is to take a clinical system (the EEG) from the lab into the real world and to democratize brain research. As already noted, older EEG machines were prohibitively expensive for smaller labs and amateur scientists and made it difficult to conduct brain research. Le and his colleagues hope to change that.
And it seems that they are destined to get their way. Coupled with similar devices from companies like Neurosky, the stage seems set for an age when brain monitoring and brain-computer interface research is something that is truly affordable – costing just a few hundred dollars instead of $10,000 – and allowing independent labs and skunkworks to contribute their own ideas and research to the fore.
As of September 16th, when the Kickstarter campaign officially closed, Emotiv surpassed its $1 million goal and raised a total of $1,643,117 for their device. Because of this, the company plans to upgrade the headset with a six-axis intertial sensor – to keep track of the user’s head movements, gait, tremor, gestures, etc. – a microSD card reader for added security, and a 3-axis magnetometer (i.e. a compass).
In some cases, these new brain-to computer interfaces are making it possible for people with disabilities or debilitating illnesses to control robots and prosthetics that assist them with their activities, rehab therapy, or restore mobility. On a larger front, they are also being adapted for commercial use – gaming and interfacing with personal computers and devices – as well as potential medical science applications such as neurotherapy, neuromonitoring, and neurofeedback.
Much like a fitness tracker, these devices could let us know how we are sleeping, monitor our emotional state over time, and make recommendations based on comparative analyses. So in addition to their being a viable growth market in aiding people with disabilities, there is also the very real possibility that neuroheadsets will give people a new and exciting way to interface with their machinery and keep “mental records”.
Passwords are likely to replace passthoughts, people will be able to identify themselves with brain-activity records, and remote control will take on a whole new meaning! In addition, mental records could become part of our regular medical records and could even be called upon to be used as evidence when trying to demonstrate mental fitness or insanity at trials. Dick Wolf, call me already! I’m practically giving these ideas away!
