Computer technology has advanced from mainframes to desktops, then laptops and palmtops and is now moving onto, and into, the human body by way of wearable computers. This type of gadget provides the ultimate in-network access, which is hands-free, heads-up operation with complete mobility. With voice activation and head-mounted or touchscreen display options, users anywhere can communicate with computers through the internet. Wearable computers bring forth a whole new concept in mobile computing, computer portability and computer miniaturization.
