"Ringbow" is a recent, half-funded Kickstarter project from a team that includes Andrew Hartman, design director of Philips Electronics. It's a Bluetooth game-controller that you wear on your finger, serving as "a mouse, keyboard and joystick simultaneously." A $35 pledge gets you one when they ship.
Since touch screens are controlled with fingers, a finger-worn tool, specifically a ring, is the natural choice for complementing them. Operating Ringbow with your thumb, in conjunction with using a touch device, enables countless new features and a much more efficient user experience. Ringbow multiplies the functionality of your finger together with allowing amazing simultaneous actions providing powerful capabilities and layers of functionality that are simply not available in today’s technologies.
