We discuss biologically inspired techniques for processing sound with a view to solving the what and where tasks. Starting from an auditorynerve like representation, we discuss an onset grouping technique for determining when to compute interaural time and intensity differences, and hence find the direction (where) of the source even in the presence of reflections. We have not yet implemented t...

Robot audition systems require capabilities for sound source separation and the recognition of separated sounds, since we hear a mixture of sounds in our daily lives, especially mixed of speech. We report a robot audition system with a pair of omni-directional microphones embedded in a humanoid that recognizes two simultaneous talkers. It first separates the sound sources by Independent Compone...

It is widely accepted that there a visual field, but the analogous notion of an auditory field rejected by many philosophers on grounds metaphysics or phenomenology audition lack necessary spatial structure. In this paper, I argue common objections to existence are misguided and that, contrary tradition philosophical scepticism about spatiality experience, it as richly experience — in some ways...

We describe a system that can provide combined auditory and haptic sensations that arise while walking on different grounds. The simulation is based on a physical model that drives both haptic transducers embedded in sandals and headphones. The model is able to represent walking interactions with solid surfaces that can creak, be covered with crumpling material. The simulation responds to press...

Selective attention contributes to perceptual efficiency by modulating cortical activity according to task demands. Visual attention is controlled by activity in posterior parietal and superior frontal cortices, but little is known about the neural basis of attentional control within and between other sensory modalities. We examined human brain activity during attention shifts between vision an...
