The mass connectivity and technological advancement created new cultural values, thus altering the human perception of the world around him. This state of affairs is jeopardizing some of the cultural identities that have surmounted few centuries, shaping the values and associated customs of numerous generations. Furthermore, the computer technology became integrated exceedingly with the modern culture, which prompted us to introduce and explore the avenues of cultural computing that is the familiar ground of the modern society. With the intention of promoting values of distinct cultures, which will greatly assist in enhancing the social relationship, we have developed a framework to communicate literature through digital media, which introduced the platform to create Poetry Mix-up.

This is because wheel skid can lead to an increase in noise and vibration from wheels with flat points, as well as an increased braking distance. However conventional anti-skid control has problems because the train wheel adhesion and skid characteristics are difficult and time consuming to accurately model. Therefore a fuzzy logic based anti-skid controller was implemented where linguistic control information could be used. In this paper the design and implementation of the fuzzy logic controller is described. Results show that the anti-skid controller has a very good performance, performing better than the previous conventional controller. The described controller is currently running in railway brake sets in both Japan and other countries

Preliminary results seemed to indicate participants’ intention to use PMRS for learning. The paper concludes with a discussion on how the findings were used to formulate a second study based on the Technology Acceptance Model, and discuss implications on intention to use and acceptance of mixed reality systems for education.

Such communications are specially attractive in virtual environments (VEs) which incorporating 3D avatars. Many of techniques for nonverbal communication in VEs have been studied and reported. However, transferring existing techniques to mobile platform are seldom reported. In this paper, we introduce our approach of creating a nonverbal communication environment between mobile phone and normal PCs. 3D face modeling is taken as an example to explain the system architecture. This modeling process is integrated with 3 platforms. The prior knowledge of modeling only uses one front view image which can be captured by built-in phone camera without high quality constrain. The two ends,between phone to phone or phone to PC, can download models from server and share the communication environment. Key techniques such as facial features detecting, face model personalizing are presented and experiment results show a lifelike face-to-face conversation can be simulated.

This field is very useful especially for applications related to computer games and virtual environments. One of the application areas is the use of real time lip tracking information for the implementation of the virtual lips in animated characters. The increased computing power of computers has made it possible to do real time lip tracking. This real time lip tracking information can be used to implement and control a virtual lip. On the other hand, the use of soft computing to represent the real time lip parameters enables us to have a more robust and flexible system which can compensate for the potential errors of lip tracking. In this paper we present a system which generates real time lip information for soft computing based virtual animated lips

It has been shown that they have high levels of both cognition and feelings and as a result there has been a recent trend of promoting poultry welfare. There is also a tradition of keeping poultry as pets in some parts of the world. However, in modern cities and societies, it is often difficult to maintain contact with pets, particularly for office workers. We propose and describe a novel cybernetics system to use mobile and Internet technology to improve human–pet interaction. It can also be used for people who are allergic to touching animals and thus cannot stroke them directly. This interaction encompasses both visualization and tactile sensation of real objects.
