Download A real-time audio rendering system for the Internet (iARS), embedded in an electronic music library (IAEM)
The internet Audio Rendering System (iARS) is an Internet browser extension extending the browser’s capabilities with real-time signal processing. The proposed system allows to receive audio streams from the Internet and apply various audio algorithms with no additional computational power needed from the server. iARS is part of the Internet Archive of Electronic Music (IAEM) project which is also presented in this paper.The IAEM is intended to be a platform to access an extensive and distributed archive of electronic music. It combines collaborative tools, real time signal processing on the client side and the content of the archive to a powerful teaching, research and publishing tool.
Download Spatial Auditory Displays - A study on the use of virtual audio environments as interfaces for users with visual disabilities
This paper presents the work on a prototype spatial auditory display. Using high-definition audio rendering a sample application was presented to a mixed group of users with visual disabilities and normal sighted users. The evaluation of the prototype provided insights into how effective spatial presentation of sound can be in terms of human-computer interaction (HCI). It showed that typical applications with the most common interaction tasks like menus, text input and dialogs can be presented very effectively using spatial audio. It also revealed that there is no significant difference in effectiveness between normal sighted and visually impaired users. We believe that spatial auditory displays are capable to provide the visually impaired and blind access to modern information technologies in a more efficient way than common technologies and that they will be inevitable for multimodal displays in future applications.
Download An auditory 3D file manager designed from interaction patterns
This paper shows the design, implementation and evaluation of an auditory user interface for a file-manager application. The intention for building this prototype was to prove concepts developed to support user interface designers with design patterns in order to create robust and efficient auditory displays. The paper describes the motivation for introducing a mode-independent meta domain in which the design patterns were defined to overcome the problem of translating mainly visual concepts to the auditory domain. The prototype was implemented using the IEM Ambisonics libraries for Pure Data to produce high quality binaural audio rendering and used headtracking and a joystick as the main interaction devices.
