摘要

PURPOSE: A system and a method for data backup of important data, a wearable computer, a mail transfer system, an image information transfer system, and a computer-readable recording medium recording a data backup program are provided to perform the data back of the important data to a device of a user, and write/search image or mail data store in the device on the user without using a PDA(Personal Digital Assistant). CONSTITUTION: The wearable computer comprises a CPU(1), a ROM(2), a RAM(3), a display panel(4), a camera(5), a GPS(Global Positioning System) function part(6), a wireless communication part(7), a switch(8), a power supply(9), a speaker(10), and a vibrator(11). The wireless communication part communicates data with the wireless communication part of the PDA through the wireless LAN(Local Area Network) connection or the WPAN(Wireless Personal Area Network) and communicates the data with the outside by connecting to the external network such as the Internet. The power supply uses an automatic winding generation typed battery charged/discharged by motion that the user shakes a hand. The vibrator vibrates the wearable computer by receiving a vibration command signal.
