A robot / an artifact which make us feel its intentions

1.在利益冲突与合作需求并存的情况下，人类如何读懂他人的心思。我们发明了两人游戏（一种非零和游戏）来模拟这种情况，并要求受试者进行游戏。在这里，玩家被要求递归地阅读他人的思想，即，了解对手如何读懂自己的心思，并根据对手的反应来控制自己的行动。通过分析主体的行为来建立心理模型。还开发了这种游戏的学习算法，并与人类的行为进行了比较。研究了凝视和面部表情在通信中的作用，并探讨了在人机通信中利用这些信息的方法。我们开发了一个机器人，它可以检测到人类的目光，并可以控制自己的目光，并评估的效果注视控制诱导一个人采取一个有意的立场，机器人，并最终读取机器人的思想.在人与人工制品的交互中，人类可能将人工制品视为具有心智。遵循丹尼特的三个姿态，即，物理的，设计的，和有意的，我们调查了什么样的立场，一个人采取的人工制品在各种条件下。首先，我们评估了确定人类采取何种立场的方法，然后研究了面对未知工件并猜测其功能的人类（受试者）的行为。得到了诱导人采取意向性立场的一些提示。

1. How humans read other's mind under the situation where the conflict of interest and the need for cooperation both exist. We invented two person game (a non-zero-sum game) simulating such a situation, and asked subjects to play the game. Here the players are made to read other's mind recursively, i.e., to read how the opponent read his own mind, and to control his action taking into account the opponent's reaction. The behavior of the subject is analyzed to make a model of mind. The learning algorithm for such a game is also developed and compared to the behavior of humans.2. The role of gaze and facial expression in communication is investigated, and the method to employ this information in man-machine communication is pursued. We developed a robot which can detect human gaze and can control its own gaze, and evaluated the effect of gaze control in inducing a human to take an intentional stance to the robot, and ultimately to read robot's mind.3. In human-artifact interaction, humans may regard artifact as having mind. Following the Dennett's three stances, i.e., physical, design, and intentional, we investigated what stance a human takes toward artifact under various conditions. First, we evaluated methods to determine what stance a human takes, and then investigated the behavior of a human (subject) who is confronted with an unknown artifact and have to guess its functions. Some hints to induce a human to take an intentional stance is obtained.
