Those muscle spasms? They’re now good for something. Okay, so Microsoft’s just-granted patent for a wearable EMG device doesn’t really thrive off of involuntary twitching and such, but it does use your movements to control your smartphone, notebook and other gadgets. The “Wearable Electromyography-Based Controller,” which we first glimpsed back in 2010, uses sensors to interpret the electrical signals generated by a user’s muscles, and then communicates with the wearer’s computer via a wireless (or wired) connection. Redmond envisions the wearable device in various incarnations: as an armband equipped with sensors, a shirt, eyeglasses and even nodes attached directly to the user’s body. In the armband example, motion control could be used to interact with a PMP while the user is jogging. No matter the setup, a calibration process allows the system to locate specific sensors and collect information based on specific gestures or movements, which mean playing Guitar Hero with only an air-guitar may someday be a reality after all.
