Indoor Navigation Study At Teacher’s College in New York

A high-contrast diagram of a route used in the study.
In the late Summer of 2016 I helped run a sample of both sighted participants and blind participants through a study evaluating the use of a real-time audio route description interface supplemented with location-specific iBeacon information.

Cognitive Map Transfer Study

In the visual condition no haptic feedback was provided, and the user's view of thump was limited to a one inch radius around the user's finger to more closely emulate the resolution of fingertip touch.

The Cognitive Map Transfer Study aims to explore how technology can help blind or visually impaired people navigate an indoor space.

Mobile Haptic Scene Access Interface

This is an example of a two-object trial in the arc's condition. Arcs a spread five feet apart, radiating out form the user, represented by the blue box at the base of the screen. The interface uses squares to represent objects. The black line represents a ray directly ahead of the user. When this ray interacts with an object, the device plays a sound. In the study, object numbers were omitted.

I collaborated with VEMI co-worker Sam Gates to develop a haptic-scene access interface to determine a usable interface design for the location of objects within a scene in relation to the user’s position. The interface utilized a head-mounted tracking system and external server to provide real-time updating information about object locations relative to the user’s location and head rotation.
