Although we've already seen various illuminated turn indicators for bicycles, the fact is that cyclists should still also be using traditional hand signals. Activating an electronic indicator while also making a hand signal, however, could be a bit of a hassle. That's where the TurnCycle comes in. It uses the rider's hand signals to automatically activate a separate LED turn indicator.

Here's how the TurnCycle works ...

The user starts by powering up a wrist bracelet, and slapping it onto their left arm. When they subsequently make a left-turn signal (arm straight out), a right turn signal (arm angled up at 90-degree angle) or a stopping signal (arm angled down), a 6-axis accelerometer in the bracelet detects the movement.

Using Bluetooth, it then transmits a signal to an LED display. That device responds by displaying a series of sweeping left- or right-facing animated arrows, or simply by flashing in the case of a stopping signal. The display turns off after 25 seconds, using an audible cue to let the rider know that it's done so.

Both components are water-resistant, with the bracelet receiving power from a coin cell battery and the display running off a USB-rechargeable lithium-ion battery.

If you're interested in getting a TurnCycle system, it's currently the subject of a Kickstarter campaign. If everything works out, a pledge of US$90 will get you a one-display package, with $180 required for a kit with both front and rear displays.

The system can be seen in use, in the following video.

hand signals in the uk are different , plus taking any hands from the handlebars is inherently unsafe, voice Recognition or an electronic means are required

Hand signals in the ''UK'' is different,Where is the "UK?"" I don't know from what a uk is......lifting your hand from the handle bar may be dangerous but not as dangerous as not signaling.......I think that since most people who ride carry a rack on their bikes should have a light bar 24 inches long with an entire row of lights,red ones in back, with bright amber turning ,flashing lights on the ends with a large arrow pointing the direction of turn,this row of lights should be at least 36 inches of the ground and a similar bar on the front.I think the bars should be at least the afor mentioned 24 inches wide as that is approximate space a bicycle needs to function safely, My trike is 36 inches wide[center of tread to center of tread] in front and 48 inches wide in back and has a wheel base of 69 inches, 2 wheels if front and 1 in the rear [of course] it is Not a recumbent,sort of, it is ,but it can be changed to an upright style depending on the way I need to use it,in cruiser mode it is semi recumbent,in work mode it becomes an upright........LOL :-)
