ArmKeypad – NEC developing tap-control interface for portable devices

Fiddling with small buttons or touchscreens on your mobile device when you're running, riding a bike or even just crossing the street can be a frustrating – and dangerous – endeavor. NEC is looking to solve this dilemma by developing a system that enables users to operate devices by just tapping their arm. The ArmKeypad is made up of acceleration sensors worn on each wrist that determine the area of the arm tapped by a user and translate this into different input commands via a Bluetooth link.
