Audio StreamerExploiting simultaneity for listening Chris Schmandt and Atty Mullins MIT Media Laboratory
More productive listening • time scaling • skipping / skimming • (SpeechSkimmer) • simultaneous listening • “cocktail party effect”
Simultaneous listening • selective attention • cues for interest on secondary channels • scenarios: • audio “channel surfing” • evening news on multiple channels • sorting old voice mail
Streamer overview • 3 simultaneous audio sources • localized sound (Beachtron, headphones) • head position sensors (Fish) • user controls gain (attention) • Streamer gives cues for interest (tone, gain)
Layout and attention switching 60’’ 60
Selective attention • we can select between simultaneous streams • streaming factors: tempo, timbre, pitch, gender, location • Streamer enhances interest by four levels of gain • gain decays, as does attention
Listener attention • More activity = greater interest • Interest decays with time
Monitoring auxiliary channels • How much do we hear? • Streamer enhances possible points of interest • Story boundaries, speaker changes
Making suggestions • tone plus increased gain • decays with time
Future work • listener evaluation • bimodal reactions so far • browsing a single recording • more interaction techniques • auditory “info landscapes”
