Closing the Gap: Designing for the Last-Few-Meters Wayfinding Problem for People with Visual Impairments
This paper comprehensively investigates the last-few-meters wayfinding problem — the gap between where GPS navigation ends (within approximately 5 meters of a destination) and where a person with visual impairment actually needs to arrive (the specif…

The Design Space of Nonvisual Word Completion
This paper presents the first design space for nonvisual word completion on mobile devices, addressing a gap where word completion interfaces — ubiquitous in sighted mobile typing — remain poorly designed for screen reader users. While sighted users …

Go That Way: Exploring Supplementary Physical Movements by a Stationary Robot When Providing Navigation Instructions
This paper explores how stationary kiosk-type robots might provide navigation instructions to blind people by supplementing verbal directions with physical movements. The work is inspired by a technique used by Orientation and Mobility (O&M) experts …

Typing Slowly but Screen-Free: Exploring Navigation over Entirely Auditory Keyboards
This paper introduces the concept of "keyflows" — entirely auditory keyboards that operate without a reference screen, enabling blind users to type while untethered from their mobile device. The core problem is that current accessible keyboards requi…
