Many studies have tried to answer an important question: is it possible to predict human visually selected regions-of-interest (hROIs)? hROIs are defined as the loci of eye fixations and they can be analyzed by their spatial distribution over the visual stimulus and their temporal ordering. We used a simplified set of geometrical spatial kernels and linear(More)
This paper presents a method for measuring 3D environment by a tracked vehicle robot using a laser range finder (LRF) with an arm-type movable unit. The unit is mounted on the robot and the LRF is installed at the end of the unit. This sensing system enables the sensor to change position and to face at a right angle to a variety of configuration. Because of(More)
We have developed a tracked mobile robot with two robotic arms which can work by itself in a disaster area. It can perform handling tasks such as gripping and carrying of a target object by the two arms as manipulators. To reduce burden of remote control on an operator for such tasks, this paper presents a method for detecting gripping positions of a(More)
It is important for multiple robots to engage tasks cooperatively and effectively. In a cooperative work, a robot needs to observe partner robots and anticipate their action. The authors have considered that visual scanpath acts as a key role to detect important regions for the action recognition of the partner because human generally attends to(More)
Top-down informativeness elaboration and bottom-up conspicuity processing are intimately interconnected in visual perception. An internal cognitive model of the external world must necessarily control not only our recognition but also the scanpath sequence of eye movement/shift of attention jumps. A self-organizing process based on principal component(More)
