Auditory signals have proven useful to guide and inform drivers in dangerous situations. Sounds can become annoying, however, thereby negatively affecting consumer acceptance of an interface or system. Auditory warnings are typically salient sounds such as sudden beeps or repetitive tones. But adding sound to the environment is not necessarily the only way(More)
Previous auditory display research has shown how fundamental aspects of an auditory signal may influence perception and impact the emotional state of the listener. However, a challenge for designers is how to find signals that correspond to user situations and make sense within a user context. In this article we present a web based application called(More)
Warning signals are often very simple and monotone sounds. This paper focuses on taking a more musical approach to the design of warnings and alarms than has been the case in the past. We present an experimental pilot study in which we explore the possibilities of using short musical pieces as warning signals in a vehicle cab. In the study, 18 experienced(More)
Sound design can be described as an inherently complex task, demanding the designer to understand, master and balance technology, human perception, aesthetics and semiotics. Given this complexity, there are surprisingly few tools available that meet the needs of the general designer or developer incorporating sound as design material. To attend to this(More)
Designing appropriate auditory warnings is a well-known challenge. The present work focuses on a new type of auditory warning for within-vehicle use, combining a signal that conveys urgency information with a signal that conveys more detailed information about the urgent event. In the study, three concepts of "combined warnings" are compared. The concepts(More)
A major problem when tackling any audio design problem aimed at conveying important and informative content, is the imposing of the designer’s own emotion, taste and value systems on the finished design choices, rather than reflecting those of the end user. In the past the problem has been routed in the tendency to use passive test subjects in rigid(More)
This paper describes the first version of Oregano, a system that allows people to interact with a large concert organ using their voices and a touch display. The main objective of the design was to increase the organ's accessibility for the general public and enhance their experience when visiting the Studio Acusticum concert hall in Piteå, Sweden. A(More)
Previous research has shown that auditory icons can be effective warnings. The aim of this study was to determine the number of auditory icons that can be learned, in a control room context. The participants in the study consisted of 14 control room operators and 15 people who were not control room operators. The participants were divided into three groups.(More)
