Figure 1: Sample application scenarios with Ambient Surface. (a) Home expansion: interacting with multiple home screen pages at once on the surface. (b) Street view mapping: showing a 3D street view for the position and orientation of the smartphone with respect to the expanded map. (c) Dynamic advertisement: making a static book advertisement into a dynamic one. (d) Wish-list: putting desired items shown in a paper magazine into the wish list on the smartphone placed on the magazine. ABSTRACTWe introduce Ambient Surface, an interactive surrounded equipment for enhancing interface capabilities of mobile devices placed on an ordinary surface. Object information and a user's interaction are captured by 2D/3D cameras, and appropriate feedback images are projected on the surface. By the help of the ambient system, we may not only provide a wider screen for mobile devices with a limited screen size, but also allow analog objects to dynamically interact with users. We believe that this demo will help interaction designers to draw new inspiration of utilizing mobile objects with ambient environment.

In this paper, we conducted for information search process of users, who have experience to buy paid-application in Appstore, to find out difference of information searching efforts and information sources, reliance on the information in term of attributes of Apps and buyes' innovativenss.As a result, Innovative buyers take a effort to search various information source but they get help buying decision-making supports by own their efforts like searching in category. On the other hand, non-Innovative buyers who search informtion less than Innovative buyers, get information like recommendation from friend and Apps, then they keep those information help buying decision-making supports highly. Besides buyers of Utility Apps search on objective information sources mainly, but those sources have influence on buying decision-making supports. On the other side buyers of Enjoyment Apps consider reliance on the information more than information searching efforts to buying decision-making supports as they get information source like popularity.This research suggests operators of Appstore and app developers how to promote their Apps to users.

In this paper, we focused on a research on a Location-Based Social Network Service to increase social interactions among people who are engaging in research and development. Since existing many of location-based social network services have only provided information of regions and social relations of users have targeted an unspecific majority of groups, they could not have active interactions, compared to users of online communities who have particular use purposes. ConAR what we designed to get over these weaknesses, aims at researches to academically exchange with others and it enables them to have social interactions with people of the same interests by helping them select discussion topics and decide assignment places simply and on impulse.
