Task analysis based on observing hands and objects by vision
نویسندگان
چکیده
In order to transmit, share and store human knowledge, it is important for a robot to be able to acquire task models and skills by observing human actions. Since vision plays an important role for observation, we propose a technique for measuring the position and posture of objects and hands in 3-dimensional space at high speed and with high precision by vision. Next, we show a framework for analysis and description of a task by using an object’s functions as elements.

Task-model based human robot cooperation using vision
We are currently engaged in advancing research in human-robot cooperation with the goal of realizing service robots in homes and offices. In order to assist humans, robots must correctly identify the tasks that humans intend to perform, and then devise strategies to perform those tasks. To accomplish this, we first define the framework of a task model for assisting a human's work. The robot the...
متن کاملThe Comparison of the Effect of Age and Object Location on the Hand Selection in the Reaching Task
The purpose of this study was to investigate the effect of age and object location on the hand selection in reaching task 120 right-handed children, adolescents and adults were selected as aur as a participant. Handedness was determined by Stanley-corn (1992) handedness Questionnaire. The tasks included lifting, reaching, and making actual use of three different objects. After the participants ...
متن کاملThe visual P2 is attenuated for attended objects near the hands.
Vision is altered when people place their hands near the object they are observing. To investigate the neural processes underlying this effect, we measured electroencephalographic visual-evoked potentials (VEPs) elicited by reversing checkerboards, while participants' hands either surrounded the visual display or rested at their sides. We found the P2 component was attenuated for hand-proximal ...
متن کاملHand position alters vision by biasing processing through different visual pathways.
The present study investigated the mechanisms responsible for the difference between visual processing of stimuli near and far from the observer's hands. The idea that objects near the hands are immediate candidates for action led us to hypothesize that vision near the hands would be biased toward the action-oriented magnocellular visual pathway that supports processing with high temporal resol...
متن کاملPersistent K-Means: Stable Data Clustering Algorithm Based on K-Means Algorithm
Identifying clusters or clustering is an important aspect of data analysis. It is the task of grouping a set of objects in such a way those objects in the same group/cluster are more similar in some sense or another. It is a main task of exploratory data mining, and a common technique for statistical data analysis This paper proposed an improved version of K-Means algorithm, namely Persistent K...
