At public spaces, signs have purposes of communicating their information clearly. Especially directional signs point out the proper route showing our surroundings. The present directional signs which are indicating 3-dimensional direction in a 2-dimensional mode seem to be difficult to understand as we are moving. This study has the purpose of investigating the role of present signs and suggesting visually effective directional signs, in particular arrows. Firstly, this study surveyed the user's attitude on directional signs in case of subway station. The research shows that the present directional signs hardly perform their roles to communicate the directional information, which means the need of newly expressed arrows. In this study we consider a new effective expression on the viewpoint of human cognition mechanism. So it is thought that those trials are helpful to efficient sign system.

This research analyzed the type of major research and support services provided by libraries in academic institutions. The research also investigated the awareness of users using the research and support services. We found that the awareness was influenced by users' major and status. In particular, prior usage of the services had statistically significant result depending on users' major and status. On the other hand, the rank of faculty members or the year of study for students were found to not have a significant influence on the general perception of the research support services. We also found that researchers require the support services in every stages of their study. In addition, the preference of training method and research guidance for such services differed by users' major.

The more mobile technology evolves, the more users are trapped in mobile technology by being encouraging the replacement with state-of-the-art technology. However, the use of device is not entirely determined by technology's attributes itself. The meaning of smartness can be varied by 'how users accept and perceive immediate spatial perception from reality to mobile space' without recognizing the boundaries between them. This study focuses on the analysis of 'smart usage' for smartphone and this is verified the concept of 'smart usage' by the second-order measurement model. The result show that the concept organization of 'smart usage' had been differentiated and elicited by the six factors - 'multifunctional use readiness', 'administrative efficiency', 'embedded media', 'device connectivity', 'user-friendly optimization', and 'external connectivity(being connected). According to the conceptual factors, 'smart usage' can be explained in an individual's autonomous ability to control a mobile interface and to utilize a wide range of applications of smartphones.

A panoramic video which supports to make viewers feel an immersion through fitting to a wide field of view (FOV) larger than the human visual angle needs an interactive viewing method such as selecting targeted view point among widely viewing points of a panoramic video because it difficult to simultaneously view a whole panoramic video due to a limited viewing environment and bandwidth. When a user officially uses a view navigation in order to select a view point, it happens waste of resources such as bandwidth owing to the transmitted video data of unnecessary view points. Therefore, this paper proposes the spatial-temporal prediction filter (STPF) which is based on the direction and velocity of the view navigation for transmitting only the necessary video data. As a result of simulation, STPF reduces bitrate saving rates by from 6% to 37% compared to conventional methods in the interactive panoramic video streaming service required high bandwidth.
