If being able to control a tablet with your mind sounds pretty cool, then imagine a device that could eventually allow you to control all of your gadgets -- all without lifting a finger.That's the big idea from Toronto-based InteraXon. Since the company's inception in 2007, the team has developed a headband it calls Muse. It's a sleek-looking device that has six sensors that rest against your forehead. The sensors read and measure the wearer's brainwaves and can translate the information to binary code. It's essentially a mobile EEG device.That code could then be interpreted by computers and other devices that can identify increases or drops in the level of activity, according to a report from Quartz. The code can hypothetically be used to control anything that's electric, the company says."With practice you can learn to manipulate your brainwave pattern, like flexing a muscle you've never used before," InteraXon says on its website.Right now Muse is primarily being used for brain-activity monitoring. "It sends those brainwaves to your smartphone or tablet showing you how well your brain is performing, and also translates your brainwaves into instructions to interact with content on your iOS or Android device," InteraXon says.Monitoring brain activity sounds about right but, as with anything that could allow people to control devices with their minds, this type of technology will need some serious real-world breaking in. Flexing your brain like a muscle will be, I assume, easier said than done for most. Or at the very least will take some getting used to.Due to begin shipping In December, InteraXon is accepting pre-orders for Muse for $199.What crazy apps and gadgets have you come across lately?

The first orders are expected to ship in December. The Basics of Brain Waves"...this dynamic system is the self in each of us."W.J. Freeman in How Brains Make Up Their MindsBrain waves are generated by the building blocks of your brain -- the individual cells called neurons. Neurons communicate with each other by electrical changes.We can actually see these electrical changes in the form of brain waves as shown in an EEG (electroencephalogram).Brain waves are measured in cycles per second (Hertz; Hz is the short form). We also talk about the "frequency" of brain wave activity.The lower the number of Hz, the slower the brain activity or the slower the frequency of the activity.Researchers in the 1930's and 40's identified several different types of brain waves. Traditionally, these fall into 4 types:- Delta waves (below 4 hz) occur during sleep- Theta waves (4-7 hz) are associated with sleep, deep relaxation (like hypnotic relaxation), and visualization- Alpha waves (8-13 hz) occur when we are relaxed and calm- Beta waves (13-38 hz) occur when we are actively thinking, problem-solving, etc.Since these original studies, other types of brainwaves have been identified and the traditional 4 have been subdivided.Some interesting brainwave additions:- The Sensory motor rhythm (or SMR; around
