Tracking eye-movements provides easy access to cognitive processes involved in visual and sensorimotor processing. More recently, the underlying neural mechanisms have been examined by combining eye-tracking and functional neuroimaging methods. Apart from extracting visual information, gaze also serves important functions in social interactions. As a deictic cue, gaze can be used to direct the ...

Etiquette, the customary code of polite behavior among members of a group, provides a means of conveying respect for others, but what is the basis for etiquette's unwritten rules? Here we show that one form of etiquette, holding a door open for another person, reflects the door holder's expectation that the person for whom he or she holds the door shares the belief that the total effort expende...

How do people respond to voice user interfaces (VUIs) that use first-person pronouns as opposed to those that use thepassive voice? We addressed this question in the context of a phone-based auction via a 2 (first person vs. passive voice) X 2 (recorded vs. synthesized speech) between-participants experiment (N=48). There were significant cross-over interactions with respect to user relaxation,...

Virtual worlds are developing rapidly over the internet. They are visited by avatars and staffed with Embodied Conversational Agents (ECAs). An avatar is a representation of a physical person. Each person controls one or several avatars and usually receives feedback from the virtual world on an audio-visual display. Ideally, all senses should be used to feel fully embedded in a virtual world. S...

This paper introduces a novel approach to enhancing safety through RFID technology, location tracking, and monitoring person-object interaction. We design and develop RFID-based wearable devices for (1)tracking people’s locations, (2)monitoring person-object interactions, and (3)tracking objects’ locations. An intelligent object reminder and safety alert system is proposed to relief the common ...

The present study described a new type of multi-person neurofeedback with the neural synchronization between two participants as the direct regulating target, termed as "cross-brain neurofeedback." As a first step to implement this concept, an experimental platform was built on the basis of functional near-infrared spectroscopy, and was validated with a two-person neurofeedback experiment. This...

We investigated whether people are able to detect in a relatively automatic manner the dominant or submissive status of persons engaged in social interactions. We used a nonaffective variant of the affective Simon paradigm of De Houwer and Eelen (1998) in which participants responded by saying either "dominant" or "submissive" depending on the right or left spatial position of a target person w...
