To support asynchronous collaboration among remote users, collaborative applications provide collaboration services and environment through virtual workspaces. In general, collaborative applications support collaboration based on desktop-based personal computers, using the features such as resource sharing or asynchronous communication among users. Unfortunately, since those applications mainly run on personal computers, they do not easily support collaborative works in various places. In this paper, we describe the development of smartphone collaborative application which provides effective collaboration facilities like resource sharing through various types of workspaces or group communication, communicating with a WebDAV-based collaboration server. The developed application provides users with high accessibility through multi-touch/touch-slide based user-interfaces in mobile environment. To support effective communication with a collaboration server, we also present a WebDAV-based collaboration library using a collaboration protocol designed to analyze easily the responses from the collaboration server.

The recent small-scaled family form is making a great influence on sharing pictures of their children with family as well. As parents are usually taking pictures of their children with their smart-phones, the form of sharing pictures with families through SNS or text messages or uploading pictures of their children in mobile mini-homepage is becoming prominent these days. But when events of an each family member taking pictures occur, such as in 'the hundredth day party' or 'first birthday party' and exchange them through text messages or SNS, it would be difficult to gather their children's picture and view them all together other than the ones that they took themselves as it is difficult to send each and every picture. Also, another problem of managing pictures occur because the source of picture all differ from each other. There fore, to solve these problems, this study intends to suggest a co-family managerial photo management mobile application UI for family members to participate in gathering and organizing pictures that they took with their own smart-phones in a specific space and produce a mobile album.

In this paper, we present a new approach to detect and recognize human face in the image from vision camera equipped on the mobile robot platform. Due to the mobility of camera platform, obtained facial image is small and pose-various. For this condition, new algorithm should cope with these constraints and can detect and recognize face in nearly real time. In detection step, ‘coarse to fine’ detection strategy is used. Firstly, region boundary including face is roughly located by dual ellipse templates of facial color and on this region, the locations of three main facial features- two eyes and mouth-are estimated. For this, simplified facial feature maps using characteristic chrominance are made out and candidate pixels are segmented as eye or mouth pixels group. These candidate facial features are verified whether the length and orientation of feature pairs are suitable for face geometry. In recognition step, pseudo-convex hull area of gray face image is defined which area includes feature triangle connecting two eyes and mouth. And random lattice line set are composed and laid on this convex hull area, and then 2D appearance of this area is represented. From these procedures, facial information of detected face is obtained and face DB images are similarly processed for each person class. Based on facial information of these areas, distance measure of match of lattice lines is calculated and face image is recognized using this measure as a classifier. This proposed detection and recognition algorithms overcome the constraints of previous approach [15], make real-time face detection and recognition possible, and guarantee the correct recognition irregardless of some pose variation of face. The usefulness at mobile robot application is demonstrated.

This research was developing a mobile-based service system through which consumers can collect labeled information on processed foods. This research collected and analyzed the labeled information of processed foods sold on the market and found that they contain abstruse standards for the information of raw nutrients and additives and are not proper for our database. Thus, to offer proper consumer-oriented information, we reclassified the information according to categories such as raw materials, additives, and nutrient information based on the food information standard of the current Food Sanitation Act, and added it to the database. Using this reprocessed information, this study developed an algorithm and applied it to a mobile-based service system, which allows consumers to use information on the labels of processed foods scientifically and clearly.

Purpose Recently the usage of Mobile Instant Messenger(MIM) has been increased all over the world. With the development of Mobile Internet, a large amount of mobile application came into being, such as WeChat, the most popular MIM now in China. It has a huge number of registered users, but just only half of them are the "active users". This study intends to examine what factors affect MIM user's continuance intention and actual usage behavior. Design/Methodology/Approach Based on the framework of Perception/Emotion-Behavior and the extended ECM-ISC (Expectation Confirmation Model of IS Continuance), this research introduced some unique variables to a user satisfaction model focusing on perceived/emotional factors in WeChat. In this model, perceived/emotional factors have been divided into enabler factors and inhibitor factors to analyze the effect on continuance intention and actual usage behavior. Also, the moderate effect of the habits was discussed. An online questionnaire survey of 203 WeChat users was conducted and the empirical validation was employed to test the research model. Findings From the empirical results, perceived usefulness, expectation confirmation, and needs for affiliation significantly affected satisfaction. Also, satisfaction influenced continuance intention which led to actual usage behavior. We found that the habit moderates the relationship between satisfaction and continuance intention. The result of this study provides guidance to the developers and operators of WeChat on how to improve enhance users' satisfaction and loyalty.

Objective: The aim of this study is to find the optimal values of sliding factors which influence the mechanical emotion of users when they use sliding type mobile phones. Background: There are various researches that study the emotion of using mobile phones. They focus the correlation between emotion words and design factors and use the commercial products by the subjects in the experiment. However, it has a limit in finding the optimal point of emotional factors because we can search the restricted values in the mass production of the products. Therefore, we will find the optimal points by realizing the full range of the user's mechanical emotion. Method: First, we need to get the detailed factors which can describe the mechanical emotion in sliding up and down the mobile phone. Next, we find the control factors by considering the correlation between the factors of the sliding emotion and the possibility of quantitative design. To find the optimal points on the control factors, we make a sliding evaluation system which can help users feel the sliding mechanical emotion by realizing control factors. Finally, we find the optimal points by doing the experiment the system being used. Results: The critical values of the factors which are the main variables of this study are Open Max Force and Dead point Ratio. The optimal point of the Open Max Force is 200~250g/f, and the Dead point Ratio is 40~50%. Conclusion: In this study we develop the sliding evaluation system to realize the control factors of the sliding type phone and find the optimal values of the critical factors. Application: The results can be used as the criteria for designing sliding type phone.

A public restroom is different from a household toilet in terms of location and a large number of sharing users. In addition, public restroom is usually messy and filthy. Recently, public toilet tends to be clearly managed than before, but it still has hygienic and clear problems. In this paper, we propose a machine-to-machine (M2M)-based public restroom management system to solve these problems, in which the system with a wireless communication device sends the status information of the toilet, such as blockage or trouble detected by a sensor, to the manager of the restroom at a remote location. In particular, we have developed a prototype management system for public restroom taking into account several system requirements, and verified the basic operations and performance of the management system. With the application of the system to public facilities, it will furnish users with more pleasant environments by restroom administrators who can respond effectively to the troubled toilet.
