We examine about ambient display to give information in proper ways for proper people. For example, we research haptic device to present information, or we implement umbrella-like device which generates vibration based on raindrops.
Research on flexible and sophisticated user interfaces that use intuition and kansei(sensitivity)-based GUI design that use metaphors in a real world is increasing. However, these approaches have a problem: users feel it is difficult to operate or manipulate objects because the objects are not substantial. To solve this problem, we propose a bi-directional user interface using ActiveCube in order to realize flexible direct manipulation interface that utilizes the user's intuition, kansei (sensitivity), and proprioception to the full.
When working in groups, we often conduct face-to-face meetings to accelerate the exchange of ideas or opinions, or to complete a cooperative task. Collaboration, a natural and efficient approach to problem solving, has been one of the most challenging topics in HCI studies. We are conducting research to facilitate face-to-face collaboration during group meetings or discussions.
The object manipulation in GUI or 3D virtual environments is an important key technology for applying daily activities in the real world metaphor to interface with a computer. We are conducting research on constructing intelligent and advanced user interfaces by utilizing knowledge on kinematics in computer-human interaction obtained from careful experiments and investigation.
Computer simulation of natural ecological systems (for example, zoological or botanical environments) has an increasingly important role in various fields. We are exploring a novel approach to interactive ecosystem simulation, carefully addressing the fragile balance and tradeoff between the autonomy of the simulated ecosystem and the freedom of user interaction.
Human motions are different in each person. If these differences can be extracted as individuality and that is applicable to other human motions, this method can be used for generation of human animation. Then, we propose a method of interactively generating human animation to extract the motion individuality from the form of a sport expert and to apply it to a variety of characters have different segment length. Using this method, we can generate skillful human animations reflected the motion individuality of expert dancers or golfers.
The Internet created an environment where barriers like political borders, culture, age, gender and language are often secondary, allowing users to communicate with strangers easily. However, the common way of communicating is still typically restricted to exchanging text messages. Several important human communication features are thus lost, such as facial expressions, conversation setting, and spatial information. These shortcomings can hinder the quality of the resulting communication, frequently leaving the users being complete strangers even after the virtual meeting ended. We believe that it is vital to retain as many real-world communication qualities when designing virtual communication systems. Our research examines and tests new ways to maintain various natural human communication features when interacting in cyberspace.
Tools are expected to provide users with good metaphors in future interactive systems for intuitively manipulating “information” or virtual objects. Moreover, by using a "virtualized" tool, we can investigate varieties of new tools by simply changing the software parameters of the tool with a standardized interface.
We propose a manipulation technique to intuitively control the viewpoint of a camera in an environment. The motion of the camera’s viewpoint interlocks with the relative motion of the user's viewpoint and his/her hand; therefore, the user can control the camera’s viewpoint with his/her natural movements. We apply the technique to the control of a “bird’s eye” viewpoint in a display system that simultaneously presents a user with both life-size local view and global overview images.
