Abstract
This study intends to utilize eye tracking for the appearance of a robot, which is one of the trends in social robot design research. We suggest a research model with the entire stage from the consumer gaze response to the perceived consumer beliefs and further their attitudes toward social robots. Specifically, the eye tracking indicators used in this study are Fixation, First Visit, Total Viewed Stay Time, and Number of Revisits. Also, Areas of Interest are selected to the face, eyes, lips, and full-body of a social robot. In the first relationship, we check which element of the social robot design the consumer’s gaze stays on, and how the gaze on each element affects consumer beliefs. The consumer beliefs are considered as the social robot’s emotional expression, humanness, and facial prominence. Second, we explore whether the formation of consumer attitudes is possible through two major channels. One is the path that the consumer beliefs formed through the gaze influence their attitude, and the other is the path that the consumer gaze response directly influences the attitude. This study made a theoretical contribution in that it finally analysed the path of consumer attitude formation from various angles by linking the gaze tracking reaction and consumer perception. In addition, it is expected to make practical contributions in the suggestion of specific design insights that can be used as a reference for designing social robots.

Robot is coming to the life of human
Personal Robot is largely divided into two: One is Service Robot, which is a type of tools for movement, maintenance, cleaning etc. and the other is Social Robot, which is distinguished from that of former in that it is regarded as a companion or family for its main purpose is to communicate at a high level including emotional exchange [1]
Studies on social robot design are classified as surface and appearance design, functional and role-based design, and interaction design including verbal-nonverbal expression
Summary
Robot is coming to the life of human. Robots initially being installed in the factory for industrial use are being transformed for personal use and spread to the daily life of diverse users. Studies on social robot design are classified as surface and appearance design, functional and role-based design, and interaction design including verbal-nonverbal expression. Researchers found out that this preference stops and decline dramatically at a certain level for people experienced unpleasant, repulsion and abhorrence [2]. This phenomenon called Uncanny Valley represents that the appearance of robots is one of the key elements in designing robots for it has great impact on people’s attitude. Collected data from survey is design evaluation on each social robot's emotional expression, humanness, and facial prominence and attitude as a dependent variable. The result of this research provides specific design guideline in designing the social robot at work
