通常，人类共生系统通过电子显示设备向用户呈现信息。然而，显示设备具有被动性质，用户需要观看它来主动获取信息。因此，它们不适合于将重要信息快速而确定地传送给指定的人。该系统希望能够识别用户的当前状态，并在周围环境的适当位置交互地呈现信息，使用户确实注意到它。在本文中，我们提出了一个交互式投影系统，始终呈现用户的视图内的信息。所提出的系统采用使用RGB-D相机估计用户的头部姿势和视场的方法。该系统遵循估计的观点，并始终使用激光微型投影仪和由PC控制的云台来投影其中的信息。因此，系统可以确定地将信息传输给用户。此外，该系统还为用户提供了一个虚拟的触摸界面，以交互式地操作投影信息。我们进行了一些实验，以证明所提出的方法效果良好。
Generally human-symbiotic systems present information to users through electronic display devices. However, the display devices have passive nature and the users need to watch it to get the information actively. Therefore, they are not suitable for transmitting important information to the specified person rapidly and certainly. The system is desired to recognize the user's current state and present information at an appropriate position on the surrounding environment interactively to make the user notice it certainly. In this paper, we propose an interactive projection system that always presents information within a user's view. The proposed system employs the method for the estimation of the user's head pose and field of view using RGB-D cameras. The system follows the estimated view and always projects information within it using laser pico-projectors and pan-tilt platforms controlled by a PC. Therefore, the system can transmits information to the user certainly. Furthermore, the system provides the user with a virtual touch interface to operate the projected information interactively. We carry out some experiments to show that the proposed method works well.
