Wireless technology is making it so that different types of gadgets can be seamlessly integrated into a network in homes and offices, but one use for wireless networking that doesn’t get quite as much attention is the ability to built networks of devices on the human body. This isn’t cybernetics like the Borg on Star Trek or the bionic man of the old TV show, though the effect is similar. These are devices that are worn on the body rather than implanted in it. The effect of these devices is similar to the science fiction idea of cybernetic implants in the sense that they’re designed to give their users greater connectivity and or entertainment while providing hands free (or nearly hands free) operation.
Of course, the devices that do this don’t have to be wireless in nature, as with the example of MP3 players and other sources of music that can be carried on the body and listened to through headphones. MP3 players- and of course their tape and CD based precursors, along with their multimedia descendants- are capable of providing an audio sound track to go along with whatever their users are doing wherever they go. The digital music players are especially good at this because even the smaller models can store and play hundreds of songs and have playback times that can last anywhere from twelve to twenty four hours on a fully charged battery. The result is a sound track that can be listened to over the course of hours- or even days- without recharging or hearing the same song twice!
Of course some of the more advanced portable media devices also come with the capability of playing video on their color LCD screens. When this capability is combined with a pair of video goggles that are becoming increasingly common on the market, active people can watch TV and movies while walking, running, or even possibly cycling if they’re brave (or foolish) enough.
