A text reader for mobile phone has a problem that the camera position is matched to a line in documents hardly. In this paper, we propose “Nail Camera System” by using character recognition to solve this problem. This system has an advantage that the position of the camera is matched to a line easily because the user attaches a small camera to user's finger. Additionally, a line can be traced by simple...
This paper describes a pedestrian collision warning system with crosswalk detection feature based on sensor fusion of a monocular camera and a millimeter wave radar. The method to decide about the presence of a pedestrian is based on the assumption that objects moving along a crosswalk can be interpreted as pedestrians under certain circumstances. The advantage of the described solution is its robustness...
This paper presents a result of walking experiment of a novel 6-axis force sensor with simultaneous plantar deformation measurement by high-speed cameras under the sensor is presented. The sensor is based on two custom beams and some strain gages in order not to be limited a view of the high-speed cameras. In walking analysis research field, the 6-axis force and plantar skin deformation are very important...
We investigated eye movement in a transportation task using remote control. Participants controlled two sets of joysticks to move a toy excavator and a toy truck monitoring the task process through video displays. They repeated the task ten times. At an early stage of skill acquisition, the participants tended to look at both task related objects (e.g., material to transport and the shovel) and the...
Near-duplicate video detection is becoming a core-technology for analyzing the structure of a large-scale video archive. It, however, is naturally an O(n2) problem, where n is a value proportional to the total length of an input video stream. We have previously challenged this time-consuming task by reducing the cost required for each of the O(n2) comparisons. This paper, on the other hand, proposes...
This paper reports the development of a reliable vision-based eye-gaze detection system for an analysis of multiple users' intention and communication. Headgear design for the gaze detection, a recording system, an off-line computation, an algorithm of the gaze extraction, and its calibration method, are mentioned. Applying the proposed system to a test case, sufficient precision of the gaze detection...

This paper presents development of a new head-mounted eye tracking system for human adaptive mechatronics (HAM) system. Estimation of human skill level is important to assist human suitability. Eye movement indicates human insight such as changing attention and intention, hence this paper focuses on design of a headgear to reduce operator's blind side and to extend scene camera image which superimposes...
This paper proposes a method for detecting edges of objects from 2D-camera image and reconstruction of the 3D-information by using a single movable camera. An adaptive VS-differentiator is used in this study for the edge detection. Apexes of the object are detected by checking the pixel layout patterns. Assuming that the camera can be moved correctly in workspace, the 3D coordinate values can be estimated...
