This paper presents ALVU (Array of Lidars and Vibrotactile Units), a contactless, intuitive,
hands-free, and discreet wearable device that allows visually impaired users to detect low …

This work introduces a wearable system to provide situational awareness for blind and
visually impaired people. The system includes a camera, an embedded computer and a …

Recently, in the attempt to increase blind people autonomy and improve their quality of life, a
lot of effort has been devoted to develop technological travel aids. These systems can …

In this paper, we present an evaluation of vibrotactile onbody feedback for the purpose of
pedestrian navigation. For this specific task, many researchers already provide different …

Navigation in complex and unknown environments is a major challenge for elderly blind
people. Unfortunately, conventional navigation aids such as white canes and guide dogs …

We present a guiding system to help blind people walk in public spaces while making their
walking seamless with nearby pedestrians. Blind users carry a rolling suitcase-shaped …

Non-visual feedback (eg, auditory and haptic) has been used as directional cues for the
blind and visually impaired (BVI) users. This paper presents the design and the evaluation of …

Vision is the principal source of information of the surrounding world. It facilitates our
movement and development of everyday activities. In this sense, blind people have great …

Intersections are critical decision points for wayfinders, but it is unknown how decision
dynamics unfold during pedestrian wayfinding. Some research implies that pedestrians …

Human-in-the-loop robot control systems naturally provide the means for synergistic human-
robot collaboration through control sharing. The expectation in such a system is that the …
