Even the best hardware is useless without apps. Thalmic Labs, maker of the Myo gesture-control armband, has publicly opened an app store with more than 100 applications.
Among the apps is one that will let a user control Parrot drones by gesture; others control Spotify or Netflix. It may be the ultimate couch potato experience to wave your arm to pause or fast-forward a movie on TV. And software to control Keynote slideshows would help make for killer presentations.
The Myo band fits around your arm just below the elbow. It senses the electrical impulses generated by muscular movement, and translates them into gestures and control. It connects to your computer by Bluetooth, and retails for $199.
