The environment of images in VR-based animation is constructed to generate and promote interactivity between the images and the viewer without any physical space like a screen, or a monitor. In this process, the images and the viewer are combined as a complex through the media technology, that is, an interface. And it is far more in the case of the animation consisted of the bio-feedback interface closely connecting with the body of viewer. As a result, the viewer experiences a permeable interaction between ego and images world, namely virtual reality. That is different from the way of seeing and interpreting the images from a distance. So it needs to analyse the perception of viewer in the world of virtual images. This paper examines the complex phenomena of both the VR-based animation and the viewer mediated by the interface in light of Media Aesthetics. Media Aesthetics is effective in analysing the phenomena of VR-based animation, for it is concerned with the perception of viewer mediated by the media technology. The perception in VR-based animation is a full-body immersion, or embodied immersion, and it is different from the contemplative immersion in that it is remediated continuously by the technological apparatus. The viewer as an immersant, especially with a bio-feedback interface, can immediately touch and control the images in VR-based animation. Such an immersion, therefore, is new every single moment. And the world of VR-based animation is ultimately constructed through the viewer's full-body, or embodied immersion crossing between the virtual and the real. So the animation is not interpreted, but embodied. And the meaning of it is constructed and reconstructed by the viewer's embodied immersion as an immersant. Here, a new frame of animation more oriented to the viewer's participation as an full-body immersant can be created.

This paper empirically analyzes determinants of DTV (Digital Television) adoption in household survey data with IT-related household demand characteristics. To this purpose, we conducted a survey for the adoption of DTV to 1,000 households nationwide. In the questionnaire, various questions asking socio-economics characteristics such as age, education, income were included. Also, status of adoption and usage of IT services such as paid broadcasting, internet, and DVD were asked. To analyze the determinants of intention of purchasing, decision of purchasing, and the timing of purchasing DTV, we adopted the ordered logit, binary logit and multinomial legit models. When there is an order among groups, ordered logit was employed and when there is no orders among groups, multinomial logit was emplyed for the estimation. It is found that when conditions of other explanatory variable are constant, the more educated household heads are, the more probable they become early adopters of DTV. It is also found that other conditions being constant, the income level of households and IT-related household demand characteristics are very important factors affecting DTV adoption. Since the likelihood of purchasing DTV is much higher for those who know the government policy of analog broadcasting termination schedule than others who do not know, dissemination of the Korean government's digital broadcasting policy will affect significantly the adoption of DTV. And policy with various incentives ought to be employed to accelerate DTV adoption, because households with the older TV sets are more likely to purchase DTV. It is suggested that the Korean government should develop policy to connect both DBS (Direct Broadcast Satellite) and DTV since DBS subscribers are more likely to be an early adopter than non-subscribers.

Smart TV is expected to take the center stage of the recent "smartization" trend in IT and consumer electronics as it performs a hub for various smart IT devices, such as smart phone, smart pad, PC, etc. It is distinct from traditional TVs or even IPTVs in the sense that it provides immersive and interactive experiences via apps downloaded through TV app store. Smart TV could serve as a new intermediary device between other smart devices and the Internet. While it started experiencing a rapid growth, little research has been conducted to understand this emerging technology in terms of its user acceptance and adoption by users. The current research attempts to fill the gap in the field by examining factors and processes for this new technology to be adopted by users. This paper draws on theories of IT acceptance and use, such as the "Unified Theory of Acceptance and Use of Technology", to investigate factors affecting "intention to use" of smart TV. The proposed research model is analyzed using the structural equation modeling approach. Findings show that such factors as innovativeness, switching cost, switching benefit, service interface, and user interface affect users' intention to use smart TV, through effort expectation, performance expectation, and social influence. Theoretical and managerial implications are discussed.

This study empirically analyzed the users' experiences with the Netflix thumbnail curation based on the Technology Acceptance Model(TAM). According to the correlation analysis results, the higher the dependence on the thumbnails, the higher the satisfaction with the thumbnail curation. Both Perceived Informational Usefulness(PIU) and Perceived Ease of Use(PEOU) had correlations with the degree of satisfaction with the thumbnail curation. In particular, the factors of relevance in PEOU had the greatest impact on the degree of satisfaction and this result proved that the suitability factors of the thumbnails had significant correlations with the degree of satisfaction. The degree of satisfaction with the thumbnail curation also positively correlated with Netflix's overall degree of satisfaction and behavioral intention to use the Netflix. This study demonstrated the suitability of the TAM as a UX evaluation tool for the Netflix thumbnail curation.
