i-Compass is the "ones own compass" that indicates the users favorite spots or destinations by a simple arrow. It supports a users free personal stroll by showing an orientation and distance instead of detailed directions. A user can register his/her favorite spot as a "POSITION" and save those multiple spots as a "SPACE." The user can upload the SPACE to the “SPACE ARCHIVE” and also download other people’s SPACE to the user’s device. i-Compass is a tool for having SPACE information in common.
