Abstract
Although devices in cyber-physical environments –
settings that are rich of connected sensors and actuators – are
getting more powerful in terms of speed and connection capabilities,
they still barely communicate with each other. By thinking
of their functionality as a service rather than treating each device
as a separate unit, new context-aware applications in several
domains could be realized. This paper presents a framework for
audio playback in cyber-physical environments named ‘Audio as
a Service’. It features a method for loudspeaker selection and
automatic adjustment of the audio output volume. This allows
pervasive audio presentation in conjunction with user position
data, while playing synchronously to an arbitrary number of
connected loudspeakers. It further implements device discovery
and a flexible interface to process and distribute auditive content.
We present the service architecture and loudspeaker selection
method, as well as results of a study showing a news reader
application based on the system.
