RobotPHONE: RUI for interpersonal communication

RobotPHONE is a Robotic User Interface (RUI) that uses robots as physical avatars for interpersonal communication. Using RobotPHONE, users in remote locations can communicate shapes and motion with each other. In this paper we present the concept of RobotPHONE, and describe implementations of two prototypes.

The SmartTool: a system for augmented reality of haptics

Previous research on augmented reality has been mainly focused on augmentation of visual or acoustic information. However, humans can receive information not only through vision and acoustics, but also through haptics. Haptic sensation is very intuitive, and some researchers are focusing on making use of haptics in augmented reality systems. While most previous research on haptics is based on static data, such as that generated from CAD, CT, and so on, these systems have difficulty responding to a changing real environment in real time. In this paper, we propose a new concept for the augmented reality of haptics, the SmartTool. The SmartTool responds to the real environment by using real time sensor(s) and a haptic display. The sensor(s) on the SmartTool measure the real environment then send us that information through haptic sensation. Furthermore, we will describe the prototype system we have developed.

Control Method for a 3D Form Display with Coil-type Shape Memory Alloy

We previously proposed a new 3D form display actuated by shape memory alloy (SMA), which is capable of displaying large scale objects sequentially. Based on our devised method, our display uses a 16×16 array of pin-rods with 30mm stroke at 5mm intervals. In this paper, we discuss the control method of the shape memory alloy with a simple matrix drive circuit. This type of drive circuit can dramatically reduce the number of switch. In addition, we propose a novel approach using linear programming, where the simulated time to display a whole shape is reduced by about 50% or more with a large number of actuators.

A teddy-bear-based robotic user interface

A robotic user interface (RUI) is part of a concept in which a robot is used as an interface for human behavior. Our RUI is a system for interpersonal exchange that uses robots as agents for physical communication. In this article we propose a new type of RUI for interactive entertainment. This RUI enables people to directly interact with the information world.

Mixed reality robotic user interface: virtual kinematics to enhance robot motion

A Robotic User Interface (RUI) is part of a concept in which a robot is used as an interface for human behavior. By combining the RUI with Mixed Reality (MR) technology, we propose a MR RUI system that enables the presentation of enhanced visual information of a robot existing in the real world. In this paper, we propose the virtual kinematics to enhance robot motion. A MR RUI system with virtual kinematics can present a selection of visual information by controlling the robot through physical simulation and by changing the parameter dynamically.
