Vocera Communications has produced a communications system that is pretty similar to the communications badges used on Star Trek. This sexy gadget connects to a local wireless network and operates on voice commands:
The Vocera Communications Badge is a wearable device that weighs less than two ounces and can easily be clipped to a shirt pocket or worn on a lanyard. It enables instant two-way voice conversation without the need to remember a phone number or manipulate a handset.
The Vocera Communications Badge is controlled using natural spoken commands. To initiate a conversation with Jim and Mary, for example, the user would simply say, “Conference Jim Anderson and Mary Guscia.” In addition, when a live conversation is not necessary, text messages and alerts can be sent to the LCD screen on the back of the Vocera Communications Badge.
