muse lets you control things with your mind
Updated version of Muse

Muse is a brain-sensing headband developed by InteraXon, a Toronto-based computing firm that creates hardware/software devices that can convert brainwaves into digital signals.

Muse allows you to control things with your mind. Things include controlling applications and games on your devices. It also helps reduce stress and can be of assistance to patients with attention deficit hyperactivity disorder or ADHD. It also helps improve memory and concentration.

Muse works with your smartphone or tablet and it is compatible with all the OS (even Linux). It has four sensors, two each on the front and on the back that measure your brainwaves in real-time. The sensors send those brainwaves to your smartphone or tablet indicating the activities of your brain and how well it is rendering; and translate your brainwaves into instructions to interact with content on your iOS or Android device.

The health benefits for this device can be said boundless, specially if you are suffering from some kind of psychological stress. According to the manufacturer, Muse can motivate your brain to enhance attention, make you more resistant to distractions and improve emotional state. It can help minimise stress and anxiety by maintaining optimal blood pressure level.
