For those who find voice control too cumbersome, a London-based startup is working on a way to control wearable devices like Google Glass with the power of thought.
The MindRDR hack - or open-source app, to use the polite term - combines wearable tech with an electroencephalography (EEG) headset. Specifically, it uses the commercially available NeuroSky MindWave Mobile device, which monitors brainwaves via a dermal patch on the forehead.
Google Glass To Come In Prescription Frames
It works like this: The EEG headset detects when the brain engages in high levels of focused concentration. Think hard enough, and you can trigger the MindRDR to send a particular instruction to Google Glass - take a picture, say.
In this case, you would focus on the image you want until a white line starts to rise on the Google Glass "screen." When the line reaches the top, Glass snaps a picture. Repeat the process to automatically post the image online. (You can pre-configure the system to work with whatever social media profile you prefer.)
