We consider the challenge of delivering location-based information through rich audio representations of the environment, and the associated opportunities that such an approach offers to support navigation tasks. This challenge is addressed by In-Situ Audio Services, or ISAS, a system intended primarily for use by the blind and visually impaired(More)
In this paper, we present building blocks for the synthesis of vowel sounds in the programming language SuperCollider. We discuss the advantages of using vowel based synthesis, and make a review where it has already been used in sonifications. Then, we describe in detail the main class Vowel which handles all parameters related to the formants that are(More)
Sound can be listened to in various ways and with different intentions. Multiple factors influence how and what we perceive when listening to sound. Sonification, the acoustic representation of data, is in essence just sound. It functions as sonification only if we make sure to listen attentively in order to access the abstract information it contains. This(More)
Through advanced recording and simulation possibilities the amount of 3D movement data is constantly growing. This data type stems from different origins ranging from sports, HCI and music research (body movements and gestures). Although these data sources look at first glance very disparate, they are in fact structurally very similar since they represent(More)
We present in this paper SonicFunction, a prototype for the interactive sonification of mathematical functions. Since many approaches to represent mathematical functions as auditory graphs exist already, we introduce in SonicFunction three new aspects related to sound design. Firstly, SonicFunction features a hybrid approach of discrete and continuous(More)
Acknowledgements I would like to thank my supervisor Thomas Hermann for all the freedom, support and lively discussions. It is a pleasure to work with him; without his active support this work would not have been possible. To my co-workers and friends in the Ambient Intelligence Group – Christian Mertes, Eckard Riedenklau and René Tünnermann – warm thanks(More)
Safety Certificate is a musical performance based on sensor data from high-speed trains. The original purpose of this data is to provide a basis for the assessments of the mechanical aspects of train safety. In this performance, the data, which represents dynamical processes below the audible range, are converted into sound through audification. The sound(More)
