First impressions play an important part in social interactions, establishing the foundation of a person's opinion about their counterparts. Since interpersonal communication is essentially multimodal, people are judged during first encounters by both verbal utterances and nonverbal behavior, such as how they utilize eye contact, body distance, orientation. In this paper, we argue that robots would provide better user experiences, including being perceived more likable if were able to make...

Various works show that proxemics occupies an important role in human-robot interaction and appropriate proxemic depends on many characteristics of humans robots. However, there is none shows the relationship between emotional state expressed by a user reaction robot to it, social these interactants. In current experiment (N = 82), we investigate this using online study which examine response (i.e., approaching, not moving, moving away) person's anger, fear, disgust, surprise, sadness, joy)...

Several works highlight how robots can navigate in a socially-aware manner by respecting and avoiding people's personal spaces. But should the robot act when there is no way around group of persons? In this work, we explore question comparing three different ways to cross two conversing people hallway environment. an online study with 135 participants, users rated robot's behavior on several items such as "social adequacy" or "disturbing" it was. The versions differ type contact intention,...

Finger touch and mouse-based interaction are today's predominant modalities to interact with screen-based user interfaces. Related work suggests that new techniques interweaving pre-touch sensing useful future alternatives. In this paper, we introduce Fich, a novel technique augments conventional interfaces tooltips further "fingerover" effects, opening up the space in front of screen for interaction. To study Fich in-depth, developed Fich-enabled weather application compared experience...
