These specifications must take into account the dynamic aspect in order to satisfy quality attributes such as adaptability, maintainability and understandability. Multimodal systems featuring fusion for natural human-computer interaction involve complex intelligent architectures to handle unexpected errors and mistakes made by users. These architectures should react to events that occur simultaneously with eventual redundancy from different input media. In this paper, dynamic based intelligent agent architectures for multimedia multimodal dialog protocols are proposed Global agents are decomposed into relevant sub-agents, called components. Each sub-agent is modeled separately. Timed colored Petri nets are used to specify the structure and behavior of each agent in our architecture and to prove that this architecture satisfies the desired structural and behavioral properties. This paper describes work in progress and presents a sound idea of designing dynamic architecture using agents for multimedia applications.","PeriodicalId":215129,"journal":{"name":"Proceedings.

However these algorithms should learn the whole data every time the number of example dialogues increases. Therefore, the learning cost is large when we construct dialogue models gradually. We proposed a learning method which decreases the number of compatibility checks by caching the merging information, and evaluated it and the perplexities of learned models. From the comparison among the dialogue models, the method which caches only the compatibility-changed states reduced the total number of compatibility checks by 13%. We also applied the algorithm to an actual conversational agent.","PeriodicalId":215129,"journal":{"name":"Proceedings.

Our hand tracking system employs multiple cameras to reduce occlusion problems. Non-synchronous multiple observations enhance system scalability. In the system, users can manipulate a virtual scene by using predefined gesture commands. We propose a statistical method to detect hand regions in images using geometrical structures involved in the appearances of the target objects. Most conventional gesture recognition systems utilize a simpler method for hand detection such as background subtractions with assumed static observation conditions and those methods are not robust against camera motions, illumination changes, and so on. Our method can describe and recognize the appearances of hands based on geometrical structures. Experimental results show the effectiveness of our method.","PeriodicalId":215129,"journal":{"name":"Proceedings.

Our system's unique contribution is handling all information as card data and associating those cards with a map. Using this system, users can share information in a map-based unified way. Our system not only stores information from users, but also organizes it. Users can therefore easily make their own plan for going out by relating more than two stored cards. They can also efficiently search for necessary information. Furthermore, in order to provide reliable information, we incorporated a function in which users can give a card positive or negative comments. If a card is given a negative comment, our system might make it invisible. Through evaluation of the prototype system, it was proved that our proposed system was effective in shaping accessibility information.","PeriodicalId":215129,"journal":{"name":"Proceedings.

One of the issues is the resource limitation of mobile terminals. We present a multimedia service composition scheme for sharing computer and communication resources by using terminals to compensate for this resource limitation. The proposed scheme is based on user authentication, service access control, and the multi-agent-based adaptive QoS control framework that we developed. We also propose a novel access mode control based on the trustworthiness of users and extension of the multi-agent-based adaptive QoS control framework to many users. Focusing on the home network as a typical ubiquitous network, we implement a prototype testbed system and show experimental results for the multimedia service composition.","PeriodicalId":215129,"journal":{"name":"Proceedings.

Developing such system necessitates tackling considerable design challenges including device shortcomings, platform heterogeneity and bandwidth limitation. In this paper we present a Java-based approach for developing a mobile surveillance system which allows PDA users to overcome these challenges. This approach applies emerging Java technologies including J2ME, RMI, and JMF for mobile computing, handheld devices, distributed computing, and multimedia computing. To achieve the thin-client goal in the post-PC era, a textual-based application-level communication protocol is also designed. We demonstrate the effectiveness of our design approach via actual experimentations on the Palm PDA. With the advent of J2ME standardization, our system is expected to be generically applicable to various handheld and mobile devices.","PeriodicalId":215129,"journal":{"name":"Proceedings.
