80. Performance Differences for Switching Sensory Modalities in Degraded Audio Environments
SessionPoster Session 1
DescriptionIn this work, we evaluated the interaction between user expectancy and degraded audio environments when shifting between audio and visual modalities for a verbal task. Previous work found performance decrements due to expectancy and modality shifting, but this has not been tested in degraded environments. However, we know that at some point, interfaces can become so degraded (e.g., audio in noisy environments) that it is better to switch to a different modality. Our study showed that when interacting with degraded audio stimuli, there was a cost of switching between modalities like that found in previous research (e.g., Spence et al., 2001). This cost was not symmetrical, with switches from audio to visual taking longer than from visual to audio. Further, we found that expectancy influenced participants’ ability to switch between modalities, with higher expectancy of audio stimuli causing worse performance when switching to the visual modalities.
