Abstract
The effect of conversational emotion on the perceived performance of models of
backchannel behaviour is evaluated. These are behavioural models which are used
to appropriately provide feedback to a speaker in a non-obtrusive manner to display
attention. The effects of anger and happiness on three models of behaviour are investigated: one proposed by researchers previously, one random, and one to copy human
behaviour. The backchannel behaviour was performed by a robot. In a user experiment subjects were shown video recordings of this behaviour during conversation
and were asked to rate the appropriateness of the behaviour. Significant effects of
both differences in emotion and model on the perceived performance of backchannel
behaviour have been found, but an interaction effect was absent.
