The use of Cone beam CT (CBCT) systems for Image Guided Radiotherapy is rapidly expanding in the developed world. With its use comes concern for the increased risks of additional radiation exposure. Quantification of the imaging dose is necessary in order to report, optimise and justify CBCT exposures. This article reviews the current methods of dose measurement and calculation including dose m...

In its attempt to offer new ways into autonomy for a large population of disabled people, assistive technology has largely been inspired by robotics engineering. Recent human-like robots carry new hopes that it seems to us necessary to analyze by means of a specific theory of anthropomorphism. We propose to distinguish a functional anthropomorphism which is the one of actual wheelchairs from a ...

This paper addresses the field of humanoid and personal robotics—its objectives, motivations, and technical problems. The approach described in the paper is based on the analysis of humanoid and personal robots as an evolution from industrial to advanced and service robotics driven by the need for helpful machines, as well as a synthesis of the dream of replicating humans. The first part of the...

The Parasitic Humanoid (PH) is a wearable robot for modeling nonverbal human behavior. This anthropomorphic robot senses the behavior of the wearer and has the internal models to learn the process of human sensory motor integration, thereafter it begins to predict the next behavior of the wearer using the learned models. When the reliability of the prediction is sufficient, the PH outputs the e...

The art of conversation is a well-known interaction type between humans. Human-computer interfaces that follow this metaphor struggle with complex problems of speech understanding, speech generation and intelligent conversational behavior in general. This paper presents an approach that gives a simple, explicit symbolic model of conversation between human and computer to be used by interface de...

This paper presents a methodology to perform a fine manipulation task with an anthropomorphic hand. We focus here on a three-finger precision grasp. The robotic hand used is the latest four finger fully actuated hand developed by the RoBioSS team of PPRIME institute. Different steps ranging from the generation of the contact points of the hand with the object to the experimental realization of ...

The concept of socio-technical systems emphasizes the mutual interrelationship between humans and machines. Accordingly, the objective of ergonomic design of socio-technical systems is to adapt the interaction between humans and machines in such a way that productivity, efficiency and humanity would not contradict each other. Hence, the human has to be considered as an integral part of the syst...

Neurology shows that human controls dozens of muscles for hand poses in a coordinated manner and such coordination is referred as to a postural synergy. The concept of postural synergies was recently adopted in the control of robotic hands. With the synergies implemented digitally in a controller, all the motors in an anthropomorphic robotic hand can be controlled via a few synergy inputs. Aimi...

Previous work has shown that gestural behaviors affect anthropomorphic inferences about artificial communicators such as virtual agents. In an experiment with a humanoid robot, we investigated to what extent gesture would affect anthropomorphic inferences about the robot. Particularly, we examined the effects of the robot’s hand and arm gestures on the attribution of typically human traits, lik...

Human emotions rely upon the ability to correctly attribute beliefs, goals and percepts to other people or social respond. Many of the quests to model human emotions derived from diverse aspects of research themes. Most of the research works related to the work of researchers in artificial intelligence, psychology, cognitive sciences as well as robotics. This research works addresses on faces f...
