Reflexive and Reflective Auditory Feedback

Quality of Experience in Telemeetings and Videoconferencing: A Comprehensive Survey

“…The motivation for this is that attention needs a trigger. Such triggering may be based on information stemming from the Perception process: When the process fails to fully match the perceived, bottom-up sensory information with a number of top-down hypotheses [263], the person is becoming aware that something is missing or wrong, which in turn can trigger the person to pay attention and focus. Those mentioned hypotheses are stored in the person's memory and are referred to as internal references; the corresponding iterative sub-processes performing this hypothesis testing are referred to as Anticipation & Matching as a top-down process, and Perceptual Event Formation as a bottom-up process, see e.g., [8], [252], [28,Chap.…”

“…At a higher level, auditory and visual objects and other perceptual features are formed based on the telemeeting characteristics captured by the human auditory and visual systems. Note that feedback mechanisms initiated at higher level may evoke topdown information that influences the bottom-up processing during auditory scene analysis [263]. However, there is not a strict one-to-one mapping of the temporal characteristics between the sensory input and the formed auditory and visual…”
