Sound Reasoning - Eye-pass

Eye-pass

Light. Precise. Fast!

Eye-pass is a lightweight orientation and mobility aid for blind and visually impaired people, designed around the latest research in assistive technologies. It complements the white cane.

Many assistive devices offer useful functionality, but bulky hardware, delayed feedback, or excessive weight can limit usability. Eye-pass builds on user feedback to address these challenges: the device weighs just 90 grams (battery and headphones included), and it responds in a few milliseconds.

We believe users don’t need interpretations: they need direct information. Eye-pass turns distance into sounds, and users interpret them on their own.
