Sensory technology company Tuso Haptics’s first product is the Aro haptic band, which is designed to help people with sensorial disabilities navigate city streets. Designer Alvaro Millan Estepa launched the startup after an encounter with a blind skateboarder, and the band has proven so successful it is now being developed for use by fully-sighted people when driving, whether that be on a scooter, a motorbike, car or bicycle. Made from recycled materials and co-designed with people who have little or no sight, Aro’s alerts feel like soft vibrations. The band’s basic instructions are left, right, forward and an emergency stop alert. The vibrations vary in frequency, intensity and location in order to provide on-the-go information. Testers used a 3D-printed map simulating typical public situations and spaces and the results were overwhelmingly positive.
