A Study of Non-verbal Expressions in a Computer-Mediated Communication context ( CMC )-Focusing on the mouse behaviors in the web contents

This paper presents an effective and direct method to study Non-verbal Cue in computer-mediated communication context (CMC). The real digital communications such as the Internet are used to the logical information converted easily into a digital signal for the communication media. However, a human communication is composed of not only logical information, but also sensitivity-like non-verbal one. Non-verbal information like the human voice, gesture, and emotion rather than verbal one is more useful to understand the user's inclination exactly. However it is quite difficult to catch the meaning of non-verbal information without using a specially purposed device such as the motion capture. Although the devices can use for the experimental purposes of understanding the meaning of non-verbal information, the confidence of results is not enough because the devices give an invisible pressure to a testee wearing the equipments. In this paper, we develop a mouse-tracking system, namely Recoding tool Of Mouse trace In The Web (ROMIT), for the purpose of studying the non-verbal information on CMC. ROMIT supports on-line communication between communicators through the Internet. It can provide more exact remote users' inclination for the system manager from avoiding the invisible pressure on the users. We investigate the user’s mouse behavior on the web by using ROMIT system, and our demonstration show that the mouse behavior of each user is the effective and direct method to understand the user's inclination. Then, we confirm that the mouse behavior can be used as the medium for transferring the KANSEI or non-verbal information on CMC.
