The day isn’t far off when it will be possible to control all home communications and automation systems by using a single wearable device that recognizes voice commands. Siemens developed such a small multi-talented communications device. It can be worn like a badge or pin on an article of clothing. The commands are transmitted via the Bluetooth short-range digital radio standard to a central home communications server. The server is equipped with voice recognition software, which converts the words into unambiguous commands for the hooked-up systems.
