Face Recognition is widely used in security systems, such as surveillance, gate control systems, and guard robots, due to their user friendliness and convenience compared to other biometric approaches. Secure face recognition systems require advanced technology for face liveness detection, which can identify whether a face belongs to a real client or a portrait. However, with the development of...

The face communicates an impressive amount of visual information. We use it to identify its owner, how they are feeling and to help us understand what they are saying. Models of face processing have considered how we extract such meaning from the face but have ignored another important signal - eye gaze. In this article we begin by reviewing evidence from recent neurophysiological studies that ...

The viewpoint aftereffect is a perceptual illusion that, after adapting to an object/face viewed from one side (e.g., 30 degrees to the left of center), when the same object/face is subsequently presented near the front view, the perceived viewing direction is biased in a direction opposite to that of the adapted viewpoint (e.g., 2 degrees to the right). In this study, we measured the face view...

This paper describes a wearable active vision system called VizWear-Active in which an active camera is used to obtain more information about the wearer and his or her environment for a wearable vision system. We have constructed the prototype system based on VizWear-Active and implemented two reflex actions: gaze direction stabilization and active tracking. For the gaze direction stabilization...

Controlled actuation of electroactive polymers with embedded high dielectric nanoparticles is theoretically analyzed. If the inclusions are placed randomly in the elastomer body, the composite always contracts along the direction of the applied field. For a simple cubic distribution of inclusions, contraction occurs if the applied field is directed along the [001] direction of the lattice. For ...

This paper presents improvement of recognition of three simultaneous speeches for a humanoid robot with a pair of microphones. In such situations, sound separation and automatic speech recognition (ASR) of the separated speech are difficult, because the number of simultaneous talkers exceeds that of its microphones, the signal-to-noise ratio is quite low (around -3 dB) and noise is not stable d...

Although gaze direction and face shape have each been shown to affect perceptions of the dominance of others, the question whether gaze direction and face shape have independent main effects on perceptions of dominance, and whether these effects interact, has not yet been studied. To investigate this issue, we compared dominance ratings of faces with masculinised shapes and direct gaze, masculi...

Gaze-cueing is the automatic spatial orienting of attention in the direction of perceived gaze. Participants respond faster to targets located at positions congruent with the direction of gaze, compared to incongruent ones (gaze cueing effect, GCE). However, it still remains unclear whether its occurrence depends on intact integration of information from the entire eye region or face, rather th...

It has been hypothesized that an evolutionarily ancient mechanism underlies the ability of human infants to detect and act upon the direction of eye gaze of another human face. However, the evidence from behavioral studies with infants is also consistent with a more domain-general system responsive to the lateral motion of stimuli regardless of whether or not eyes are involved. To address this ...
