The paper proposes a GUARD (GUide, Alarm, Recovery, and Detection) system for the blind. The main goal of the GUARD system is to construct an obstacle-aware wireless sensor network and provide guide, alarm, recovery, as well as detection functions for the blind to guarantee his safety and convenience at Tamkang University. Some hardware components as well as communication and management protocols are implemented in the GUARD system.
