Smart Dining Table is an ongoing project in our Interaction Design Lab. It is a table top display designed to facilitate dining process. Smart Dining Table uses touchable interface to interact with users, providing a new, interesting and efficient experience in dining process. In GuangZhou, the south city of China, Yam Cha is a traditional and local way of entertainment in which normally elders gather together with friends or relatives to have tea and snack, and most importantly, to chat. Yam Cha has a long history in China, and Guangzhou has developed its own unique "Yam Cha" culture. In this paper, we discuss about previous research we did on Yam Cha in GuangZhou, and the approach we propose to manage and analyze issues related to dining table to help designing specific version of Smart Dining Table which can fit right into the Yam Cha process and cultural environment.

The food culture has been advanced with technical developments. The technical advances of food refrigeration and refrigerated transport system enable people to enjoy raw and fresh foods in the middle of dessert and in current days the development of information technology helps people to get variable information as like the information of food stuffs, freshness, the history of cooking, other useful information. We need to research the information architecture of food culture, which means Information technology grafts on the food culture, to provide diverse services that information technology utilized. As the first step of our research, we define the context of food culture for integration of food culture and Information technology, and find out the relationships between each factors. This research is considered the food culture as a medium between human to human relationships and the food, and redefined it with a relationship viewpoint. We've selected Yam cha that is one of the famous foods in southern China as a research item and referenced data that we researched with students in Guangzhou College of Art, China.

The Ce-doped YAG(Yttrium Aluminum Garnet, $Y_3Al_5O_{12}$) phosphor powders were synthesized by Sol-gel method. The luminescence, formation process and structure of phosphor powders were investigated by means of XRD, SEM and PL. The XRD patterns show that YAG phase can form through sintering at $1000^{\circ}C$ for 2h. This temperature is much lower than that required to synthesize YAG phase via the conventional solid state reaction method. There were no intermediate phases such as YAP(Yttrium Aluminum Perovskite, $YAlO_3$) and YAM(Yttrium Aluminum Monoclinic, $Y_4Al_2O_9$) observed in the sintering process. The powders absorbed excitation energy in the range 410~510nm. Also, the crystalline YAG:Ce showed broad emission peaks in the range 480~600nm and had maximum intensity at 528nm.
