DeafBlind and multimodal access
Different people need different sensory channels. The technology should adapt to the person, not the other way around.
← Sensory Awareness overviewDesign without assuming sight or hearing
DeafBlind access cannot rely on a visual notification as the only fallback. A tactile cue may attract attention, while a connected refreshable Braille display could communicate the event name, location or recommended action.
People have different tactile experiences, Braille fluency, devices and preferences; no single delivery method will suit everyone.
An illustrative sequence
1. Touch: a user-selected attention vibration.
2. Detail: a Braille display could show “Visitor at front door.”
3. Control: the user chooses which events deserve attention.
This is a proposed interaction, not a working Sensivo demonstration.
Co-design is essential
Recognizability
Evaluate whether information can be identified from touch alone.
Comfort and control
Test vibration strength, pattern confusion, customization and alert fatigue.
Compatible outputs
Investigate device integration and nonvisual access paths, including Braille.
