The GUARDIAN deaf-mute helmet revolutionizes cycling safety for individuals with hearing impairments by integrating advanced smart features. Equipped with a rear-vehicle detection system, it proactively senses traffic conditions, issuing timely warnings of potential dangers. Linked with a navigation system, it provides real-time information for safe and accurate travel. A turn reminder function, employing vibrations or visual cues, enhances safety at intersections. The collision warning system anticipates obstacles, and a cycling record function documents any accident events. The GUARDIAN not only addresses the specific safety needs of deaf-mute cyclists but also sets a new standard for comprehensive, secure, and convenient cycling experiences.
