Big Tech Is Trying to Innovate Beyond the Black Rectangle Dead End

Works Like a Marionette: Estimated to begin deliveries in March, Mudra Band for Apple Watch allows you to navigate the interface without ever touching it. Use its gesture-controlled software to check text messages—or your heart rate—by merely waving your fingers over the screen, like a modern-day, tech-savvy Geppetto. The $179 device is compatible with Apple Watch Series 3 and above.
