<Year 2002>1.The author studies the context of competitive task model, and proposed to employ the Markov model for analysis of the opponent player's behavior in the online battle game. The workability of the proposed method is evaluated. On the otter hand, the online racing game is prototyped to examine the adaptive prediction filter 'invented by the author and confirm its range of adaptability2.As an application of the, context of co-operative Task model, a path-tracing type of,task performance is implemented which provides both users (i.e., the leader and the follower) with linear prediction of opponent avatar's attributes, for evaluation of the validity of the CSCW system depending on the prediction algorithm and the amount of lag3.As a method of real-tithe three-dimensional remodeling of 3D shape, the authors invented a high-speed and ambiguity-free remodeling scheme<Year 2003>4.The relationship between a latency factor including time lag and update frequency, and the loss of infor … More mation caused by the factor is theoretically analyzed. That is, by employing the update frequency teased Taylor expansion f「r upcoming data from the remote peer, the author proposed that the prediction of arbitrary accuracy is performed for remote avatar's behavior. The numerical simulations evaluate the applicable range of this schema5.As an application of' the context of competitive task model, networked field type of DVE is mathematically defined and the peer-to-peer protocol Is originally introduced for the model6.As an application of the context of co-operative task model, multi-player type of "coro-coro maze" is prototyped. This is the game where users collaboratively manipulate a virtual plate on which a ball moves on the path of the maze, so as to get the goal. By using this game as a benchmark for a basic collaboration task, various algorithms and protocols can be examined7.As an application of a weak interactivity model, the demote musical ensemble system and the communication tool for remote education were developed. The former is based on concept of regulation of latency considering the amenity of musical play. The latter is for both of synchronous end asynchronous type of remote education Less

< 2002年> 1。作者研究了竞争任务模型的背景，提出了利用马尔可夫模型分析在线战斗游戏中对手玩家的行为。最后对该方法的可行性进行了评价。另一方面，以在线赛车游戏为原型，检验作者发明的自适应预测滤波器，确定其自适应范围2。作为协作任务模型上下文的应用，实现了一种路径跟踪类型的任务性能，为用户（即领导者和追随者）提供对手角色属性的线性预测，以便根据预测算法和lag3的量来评估CSCW系统的有效性。作为一种对三维形状进行实时三维重构的方法，作者在2003年发明了一种高速无模糊的三维重构方案。从理论上分析了时延和更新频率等延迟因素与该因素引起的信息丢失之间的关系。也就是说，通过对来自远程对等体的即将到来的数据进行更新频率戏弄Taylor展开，作者提出对远程虚拟角色的行为进行任意精度的预测。通过数值模拟对该方案的适用范围进行了评价。作为“竞争任务上下文模型”的一种应用，从数学上定义了网络场类型的分布式虚拟机，并最初为该模型引入了对等协议6。作为合作任务模型情境下的应用，本文设计了多人模式的“coro-coro迷宫”原型。在这款游戏中，玩家需要协同操作一个虚拟的盘子，在这个盘子上有一个球在迷宫的路径上移动，从而达到目标。通过使用这个游戏作为基本协作任务的基准，可以检查各种算法和协议7。作为弱交互模型的一种应用，开发了用于远程教育的远程音乐合奏系统和通信工具。前者是基于考虑音乐演奏舒适性的延迟调节概念。后者是针对双方的同步端异步式远程教育较少
