Thanks to noninvasive tools that have been around for decades, such as electroencephalography EEG and functional magnetic resonance imaging fMRI , physicians and neuroscientists can measure changes in your brain without drilling a hole in your skull. And now some of the problems that made these tools finicky, expensive and hard to interpret are being ironed out, meaning that neural interfaces are suddenly showing up at Amazon and Target.
Which presents a challenge because measuring brain activity isn't like making microwave popcorn. There are enormous privacy and ethical issues at stake. The story of Toronto-based InteraXon, a brain-machine interface start-up founded in , shows how fast things are changing.
Getting reliable brain-wave measurements via EEG used to mean pasting dozens of electrodes to a subject's scalp. But InteraXon built a wearable EEG device with just a few electrodes that rest against the forehead and behind the ears, along with software to classify the brain waves they measure.
The company's first applications were on the whimsical side. Visitors to the Ontario pavilion at the Winter Olympics in Vancouver could don a headband and use their thoughts to control the lights shining on Niagara Falls and other distant Ontario landmarks. Later the company built thought-controlled slot cars and Star Wars games.
Frankly, you could just turn the thing with your hand much more readily. So you've been tapping the charts or working toward tapping the full chart and a game to play with the individual sounds would be helpful. Some children need many repetitions with the work to 'remember' it. Use this type of game board with any chart 1st, Blends, Teams or Syllable.
