چکیده

We evaluated effects of gaze directional and other non-verbal visual cues on multiparty mediated communication. Groups of three participants (two actors, one subject) solved language puzzles in three audiovisual communication conditions. Each condition presented a different selection of images of the actors to subjects: (1) frontal motion video with 14% gaze; (2) motion video with head orientation and 7% gaze; (3) still images with head orientation and 32% gaze. Presence of head orientation cues caused subjects to use twice as many deictic references to persons. We found a linear relationship between the amount of actor gaze perceived by subjects and the number of speaking turns taken by subjects. Lack of gaze can decrease turn-taking efficiency of multiparty mediated systems by 25%. This is because gaze conveys whether one is being addressed or expected to speak, and is used to regulate social intimacy. Support for gaze directional cues in multiparty mediated systems is recommended.

Probabilistic Inference of Gaze Patterns and Structure of Multiparty Coversations from Head Directions and Utterances

A novel probabilistic framework is proposed for inferring gaze patterns and the structure of conversation in face-to-face multiparty communication, based on head directions and the presence/absence of utterances of participants. First, we define three classes of conversational regimes, which are characterized by the topology of the gaze pattern; we assume that they indicate the structure of the...

Gaze and Conversation Dominance in Multiparty Interaction

With the goal of designing conversational agents that can join and manage conversations with multiple participants, in this paper, we conduct an experiment to collect multiparty conversations with a virtual agent, and recognize head direction as each participant’s focus of attention. Then, we analyze how gaze and mutual gaze affect floor management and conversation dominance; we assumed that th...

Theories and Methods in Mediated Communication

Computer mediated communication 2. .. 1. Theories and Methods Technology mediated communication is a fact of life. The human communication apparatus is constrained in several ways. There are limits to the distance at which speech is audible, and visible behaviours such as gesture, gaze or facial expressions are perceivable. Furthermore, these natural communication behaviours are ephemeral and d...

Design and formal verification of DZMBE+

In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...
