Microsoft Patents Wearable That Responds to Sound

More wearables: Microsoft has gotten a patent for wearables that respond to sound. “Incorporating a microphone, the device – which doesn’t have a touch screen – will enable you to scratch the arm of say the family room leather chair with that unique sound wave controlling the change of channels or audio on your TV.” Or I’ll just attach one to the cat, point her toward the arm of her favorite scratching couch, and call it performance art.
