Abstract

For persons with visual impairment, forming cognitive maps of unfamiliar interior spaces can be challenging. Various technical developments have converged to make it feasible, without specialized equipment, to represent a variety of useful landmark objects via spatial audio, rather than solely dispensing route information. Although such systems could be key to facilitating cognitive map formation, high-density auditory environments must be crafted carefully to avoid overloading the listener. This article recounts a set of research exercises with potential users, in which the optimization of such systems was explored. In Experiment 1, a virtual reality environment was used to rapidly prototype and adjust the auditory environment in response to participant comments. In Experiment 2, three variants of the system were evaluated in terms of their effectiveness in a real-world building. This methodology revealed a variety of optimization approaches and recommendations for designing dense mixed-reality auditory environments aimed at supporting cognitive map formation by visually impaired persons.

An RSS-feed auditory aggregator using earcons
AM '11: Proceedings of the 6th Audio Mostly Conference: A Conference on Interaction with Sound

In this work we present a data sonification framework based on parallel/concurrent sonic earcons' representations for monitoring in real-time information related to stock market. The information under consideration is conveyed through the well-known ...
Noise-cancelling, steps and soundscapes: the effect of auditory stimulation on presence in virtual realities while walking
VRST '16: Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology

This study investigates the influence of different auditory stimuli on perceived presence, the feeling of "being there", on a walk through a park-like virtual environment. A single-factorial design with five levels varying the surrounding sound ...
A comparison of artificial driving sounds for automated vehicles
UbiComp '15: Proceedings of the 2015 ACM International Joint Conference on Pervasive and Ubiquitous Computing

As automated vehicles currently do not provide sufficient feedback relating to the primary driving task, drivers have no assurance that an automated vehicle has understood and can cope with upcoming traffic situations [16]. To address this we conducted ...
