The concept of a small 2-DOF camera-orientation system is presented and verified through prototype testing. This system is able to orient a camera around its pan and tilt axis with dynamics exceeding those of the human eyes. At the same time, the system is lightweight enough to be mounted on a human's head. These characteristics are very important, considering the application as part of a gaze-driven...
For successful deployment, personal robots must adapt to ever-changing indoor environments. While dealing with novel objects is a largely unsolved challenge in AI, it is easy for people. In this paper we present a framework for robot supervision through Amazon Mechanical Turk. Unlike traditional models of teleoperation, people provide semantic information about the world and subjective judgements...
In this paper, a method for hand posture recognition, which is robust for hand posture changing in an actual environment, is proposed. Conventionally, a data glove device and a 3D scanner have been used for the feature extraction of hand shape. However, the performance of each approach is affected by hand posture changing. Therefore, this paper proposes the posture fluctuation model for efficient...
For a coexisting and collaborative society that incorporates humans and robots, the detection, tracking, and recognition of human motion are indispensable techniques for a robot to safely and securely interact with humans. The present paper proposes a motion tracking system using distributed network cameras that are placed in a sizeable environment, such as a street or a town. Model-based motion tracking...
To realize accurate recognition of human activities, many studies have been proposed using vision sensors. Vision sensors can reliably detect human in normal environment, but it is affected by sudden illumination changes and complex conditions, which are the major obstacles to the reliability and robustness of the system. To solve this problem, we proposed a novel integration method to combine bi-static...
In this paper, we discuss a robot vision in order to perceive people and the environment around a mobile robot. We developed a tele-operated mobile robot with a pan-tilt mechanism composed of a camera and a laser range finder (LRF). In this paper, we propose a method for sensor fusion to extract a human from the measured data by integrating these outputs based on the concept of synthesis. Next, we...
