Effects ofHand Color Change on User's Psychological State During a Pseudo Handshake

Abstract: In recent years, social VR (Virtual Reality) contents for communication have become more and more active. However, social VR contents cannot convey a sense of touch or warmth during the pseudo-body contact. This study investigated whether changing the color of a hand during the pseudo-body contact in virtual reality can produce temperature sensations and a sense of contact from visual stimuli. In addition, changing the color of the hand may affect not only the temperature illusion but also the user’s psychology. Therefore, in order to induce the temperature illusion, the color of the hand during the simulated handshake was changed, and the evaluation of the sense of contact, closeness, and the user’s psychological state was investigated in a subject experiment. The results showed that warm colors of the hands can make users feel warm and enhance the sense of contact. When the color of one’s own hand and the other’s hand were warmer than each other, the feeling of closeness increased. When the other person’s hand is in the cold color, people feel coldness, and increase negative feelings toward the other person, such as a decrease in happiness, and a feeling of anxiety and disgust. By investigating and clarifying the effects of pseudo-body contact in a virtual space, this study contributes to providing an environment for high quality communication in social VR contents.

Multimodal Analysis of Handshake Etiquette at a State Visit Welcome Ceremony based on the ELAN Program

Abstract: The handshake is an important element of etiquette in many cultures. It is used in various, not only official, but also informal situations that express greetings, farewells, gratitude, etc. In this work, the object of study is the etiquette of shaking hands during the welcome ceremony of a state visit. The subjects of the study are various modalities and their meanings when performing a handshake. The authors consider in detail such aspects as the requirements of a handshake in official communication: the duration of the handshake, the distance between the communicants, the types of modalities: facial expressions, visual gaze, body movement. Particular attention is paid to highlighting and analyzing the significance of handshake modalities during the welcoming ceremony. The conducted research provides information about the meaning of the handshake and the role of other non-verbal modalities: distance, gestures, gaze and facial expressions, which are designed to demonstrate politeness in a communicative situation. A special contribution of the authors to the study of the topic is to identify the function and meaning of various modalities during a handshake. The study helps to study the expression of politeness in various modalities during a welcome ceremony. The novelty of the study lies in the analysis of etiquette in terms of multimodality. Using the ELAN software, the modalities of the handshake at the ceremony are displayed visually, which allows statistical methods to match verbal and non-verbal elements during the handshake.

Efficient Synchronous MAC Protocols for Terahertz Networking in Wireless Data Center

Abstract: Terahertz communication is emerging as a potential technology to support thousands of Gbps throughput and ultra low delay. Therefore, it is regarded as a future technology for data center networking. However, the unique characteristics of Terahertz bands make it extremely challenging to design efficient Medium Access Control (MAC) protocols for Terahertz wireless data centers. Specifically, the problems of low channel utilization and lack of quality of service support in Terahertz networking should be well investigated. In this paper, we propose a centralized Terahertz networking architecture for wireless data center with two efficient synchronous MAC protocols. To solve the problem of low channel utilization caused by the involvement of directional antennas, we design an efficient High Channel Utilization MAC protocol called HCU-MAC based on “CSMA+TDMA” techniques and a novel two-way handshake procedure. To support Quality of Services (QoS) for Terahertz networking, we propose a TDMA-based one-way handshake MAC protocol called HTS-MAC. The proposed MAC protocols are implemented and evaluated in NS-3. Simulation result reveals that our proposed MAC protocols achieve high channel utilization and data transmission success rate, which outperforms the state-of-the-art Terahertz MAC protocol and provides a valuable design reference for future Terahertz wireless data center.
