Sunu, Inc. is a company founded in 2013 and headquartered in Boston, Massachusetts, dedicated to enhancing mobility and awareness for individuals with low vision and blindness. The company develops the Sunu Band, an innovative smart band that employs sonar technology to assist users in navigating their environments. This device emits high-frequency sound waves that bounce off nearby objects, translating the distance to these obstacles into distinct vibratory patterns. By providing real-time feedback through gentle vibrations, the Sunu Band helps users identify objects and obstacles, reducing the risk of accidents and promoting greater confidence in mobility. It can be used alongside traditional mobility aids, such as canes and guide dogs, to enhance spatial awareness in a discreet manner. The Sunu Band represents a significant advancement in assistive technology, aimed at improving the everyday experiences of those with visual impairments.
