Manipulation mentale

vignette|upright=1.0|Vue d'artiste de la coercition et du lavage de cerveau. Une manipulation mentale ou manipulation psychologique est une méthode délibérément mise en œuvre dans le but de contrôler ou influencer la pensée, les choix, les actions d'une personne, via un rapport de pouvoir ou d'influence (suggestions, contraintes). Les méthodes utilisées faussent ou orientent la perception de la réalité de l'interlocuteur en usant notamment d'un rapport de séduction, de suggestion, de persuasion, de soumission non volontaire ou consentie. Même si la manipulation mentale fait penser aux sectes ou au lavage de cerveau, elle entre en jeu dans les relations quotidiennes et concerne aussi bien les individus que les foules. Elle peut même avoir une perception positive dans le cas de la séduction amoureuse. Elle reste cependant mal connue malgré les nombreuses expériences réalisées et concepts développés (influence sociale, ingénierie sociale, soumission librement consentie, domination, pr

Contactless optical trapping and manipulation of nanoparticles utilizing SIBA mechanism and EDL force

Mahdi Sahafi

On-chip optical tweezers based on evanescent fields overcome the diffraction limit of the free-space optical tweezers and can be a promising technique for developing lab-on-a-chip devices. While such trapping allows for low-cost and precise manipulation, it suffers from unavoidable contact with the device surface, which eliminates one of the major advantages of the optical trapping. Here, we use a 1D photonic crystal cavity to trap nanoparticles and propose a novel method to control and manipulate the particle distance from the cavity utilizing a self-induced back-action (SIBA) mechanism and electrical-double-layer (EDL) force. It is numerically shown that a 200 nm radius silica particle can be trapped near the cavity with a potential well deeper than 178k(B)T by 1 mW of input power without any contact with the surface and easily moved vertically with nanometer precision by wavelength detuning.

ManiGaze: a Dataset for Evaluating Remote Gaze Estimator in Object Manipulation Situations

Bozorgmehr Aminian, Jean-Marc Odobez, Rémy Alain Siegfried

Gaze estimation allows robots to better understand users and thus to more precisely meet their needs. In this paper, we are interested in gaze sensing for analyzing collaborative tasks and manipulation behaviors in human-robot interactions (HRI), which differs from screen gazing and other communicative HRI settings. Our goal is to study the accuracy that remote vision gaze estimators can provide, as they are a promising alternative to current accurate but intrusive wearable sensors. In this view, our contributions are: 1) we collected and make public a labeled dataset involving manipulation tasks and gazing behaviors in an HRI context; 2) we evaluate the performance of a state-of-the-art gaze estimation system on this dataset. Our results show a low default accuracy, which is improved by calibration, but that more research is needed if one wishes to distinguish gazing at one object amongst a dozen on a table.

A Modular Approach to Learning Manipulation Strategies from Human Demonstration

Aude Billard, Ravin Luis De Souza, Miao Li

Object manipulation is a challenging task for robotics, as the physics involved in object interaction is com- plex and hard to express analytically. Here we introduce a modular approach for learning a manipulation strategy from human demonstration. Firstly we record a human perform- ing a task that requires an adaptive control strategy in differ- ent conditions, i.e. different task contexts. We then perform modular decomposition of the control strategy, using phases of the recorded actions to guide segmentation. Each mod- ule represents a part of the strategy, encoded as a pair of forward and inverse models. All modules contribute to the final control policy; their recommendations are integrated via a system of weighting based on their own estimated er- ror in the current task context. We validate our approach by demonstrating it, both in a simulation for clarity, and on a real robot platform to demonstrate robustness and capacity to generalise. The robot task is opening bottle caps. We show that our approach can modularize an adaptive control strategy and generate appropriate motor commands for the robot to accomplish the complete task, even for novel bottles.
