Peters, C. and O'Sullivan, C. 'Bottom-up visual attention for virtual human animation' in proceedings of the 16th International Conference on Computer Animation and Social Agents (CASA 2003), IEEE Computer Society, 2003, pp 111 - 117.
We present a system for the automatic generation of
bottom-up visual attention behaviours in virtual humans.
Bottom-up attention refers to the way in which the
environment solicits one’s attention without regard to
task-level goals. Our framework is based on the
interactions of multiple components: a synthetic vision
system for perceiving the virtual world, a model of
bottom-up attention for early visual processing of
perceived stimuli, a memory system for the storage of
previously sensed data and a gaze controller for the
generation of resultant behaviours. Our aim is to provide
a feeling of presence in inhabited virtual environments by
endowing agents with the ability to pay attention to their
