Although the vast majority of research in human-computer interaction often involves only our senses of sight and hearing, with sporadic forays into touch, future laboratories used in engineering education will mostly benefit from developments beyond video and sound. Tangible and embedded interaction, augmented and mixed reality characterizes ultimate(More)
In a MiroSOT robot soccer program, operators manually adjust color setting using global vision system for detecting objects such as robots and a ball. It is a cumbersome and time-consuming operation before the game. Since spectators may make shadows and illumination changes on the pitch, it becomes more difficult to detect colors of the objects. For the(More)
A robot is expected to carry out a task autonomously with its own knowledge system. Using the knowledge system, the robot can recognize current situation and recall a proper sequence for performing an appropriate task in that situation. To build such knowledge system, the robot learns the knowledge from user demonstrations as if a child learns through(More)
This paper proposes a Reward-based Electromagnetic Adaptive Resonance Theory (REM-ART) mainly for reducing the retrieval error, which can store and retrieve episodes consisting of a temporal sequence of events. With the existing EM-ART it is difficult to predict a correct episode when there are noisy inputs that are sparse or distorted. To overcome this(More)
Various types of robots have been built and used in our daily life for various purposes. One of them is an assistive robot that can autonomously perform a proper task in a given situation. The robot is required to integrate constituent algorithms into one controlled architecture for the autonomous operation. In this paper, we categorize the constituent(More)
The advanced simulation technology with the rapid growth of computing power leads many new approaches towards design of robot systems. In the typical top-down design of a robot system, the design of the lower phase would be limited by the design from the higher phase. Moreover, it is difficult to well-design the higher phase in predicting problems of the(More)
Episodic memory is the memory of personal experiences as episodes with subjective time. Task memory is defined as a memory for storing the knowledge of sequential procedures to perform tasks. Rather than encoding and retrieving such a temporal sequence of events or procedures, respectively, it is more efficient to implement both memories into a single(More)
Recognizing mathematical expression is important to reduce time in converting image-based documents like PDF to text-based documents that are easy to use and edit. In case of general character recognition, the sequence of character segmentation is from left to right, and from top to bottom. However, mathematical expression is a kind of twodimension visual(More)
