Abstract
This work forms a part of a wider project, in which the author is developing a system to present visual images, and other material, via sets of auditory (and tactile) display effects. The main contribution of this paper is to describe the design, and examine the effectiveness, of these effects in an automotive context, specifically in the context of blind drivers travelling in autonomous (self-driving) vehicles. This paper also brings together and summarizes auditory display effects and techniques that have previously been reported by the author, and describes several new features. The effects are termed tracers; polytracers; drone and matrix effects; imprints; and multi-level multi-talker ﾓfocusﾔ effects. The paper describes the potential automotive application of such auditory display effects in:- command and control; route presentation; maps/cartography; and enhancing the journey experience of blind travelers. Methods of presenting rectangular areas within a scene, (termed ﾓaudio previewsﾔ) are described and discussed, as is the concept of a small set of effects termed a ﾓglimpseﾔ. The results of informal assessment sessions with a totally blind person, and two sighted people, are described.
