Similarities and differences between eating disorders and obese patients in a virtual environment for normalizing eating patterns.

2016

Virtual reality has demonstrated promising results in the treatment of eating disorders (ED); however, few studies have examined its usefulness in treating obesity. The aim of this study was to compare ED and obese patients on their reality judgment of a virtual environment (VE) designed to normalize their eating pattern. A second objective was to study which variables predicted the reality of the experience of eating a virtual forbidden-fattening food. ED patients, obese patients, and a non-clinical group (N = 62) experienced a non-immersive VE, and then completed reality judgment and presence measures. All participants rated the VE with similar scores for quality, interaction, engagement,…

You’ve Got Photos! The design and evaluation of a location-based media-sharing application

2008

PhotoJournal is a novel location-based media sharing appli- cation that enables users to build interactive journals that associate multimedia files with locations on maps and share this information with other users. Its underlying informa- tion discovery and sharing mechanism is 7DS that runs in either pure peer-to-peer or centralized server-to-client mode, depending on the availability of a server and/or an infras- tructure. 7DS-enabled devices act as miniature caches, shar- ing information with each other. When access to an informa- tion server (e.g., web server) is not available, the local 7DS instance running on the device enables the device to search and access information from other p…

Synthesis and biological activities of a new class of heat shock protein 90 inhibitors, designed by energy-based pharmacophore virtual screening

2013

The design through energy-based pharmacophore virtual screening has led to aminocyanopyridine derivatives as efficacious new inhibitors of Hsp90. The synthesized compounds showed a good affinity for the Hsp90 ATP binding site in the competitive binding assay. Moreover, they showed an excellent antiproliferative activity against a large number of human tumor cell lines. Further biological studies on the derivative with the higher EC50 confirmed its specific influence on the cellular pathways involving Hsp90.

Comparative analysis of virtual screening approaches in the search for novel EphA2 receptor antagonists

2015

The EphA2 receptor and its ephrin-A1 ligand form a key cell communication system, which has been found overexpressed in many cancer types and involved in tumor growth. Recent medicinal chemistry efforts have identified bile acid derivatives as low micromolar binders of the EphA2 receptor. However, these compounds suffer from poor physicochemical properties, hampering their use in vivo. The identification of compounds able to disrupt the EphA2-ephrin-A1 complex lacking the bile acid scaffold may lead to new pharmacological tools suitable for in vivo studies. To identify the most promising virtual screening (VS) protocol aimed at finding novel EphA2 antagonists, we investigated the ability of…

Minimally invasive superficial temporal artery to middle cerebral artery bypass through a minicraniotomy: benefit of three-dimensional virtual realit…

2009

Object The aim of the authors in this study was to introduce a minimally invasive superficial temporal artery to middle cerebral artery (STA-MCA) bypass surgery by the preselection of appropriate donor and recipient branches in a 3D virtual reality setting based on 3-T MR angiography data. Methods An STA-MCA anastomosis was performed in each of 5 patients. Before surgery, 3-T MR imaging was performed with 3D magnetization-prepared rapid acquisition gradient echo sequences, and a high-resolution CT 3D dataset was obtained. Image fusion and the construction of a 3D virtual reality model of each patient were completed. Results In the 3D virtual reality setting, the skin surface, skull surface…

The Users’ Perspective

2014

In this chapter 20 former research subjects in brain–computer interface (BCI) studies answer questions concerning their experiences with this novel technology. They talk about their state of information, their expectations, their achievements, and also their disappointments. The answers display a wide spectrum of attitudes and personal assessments ranging from enthusiastic appreciation to skeptical reservation. Many users mention the current shortcomings but also stress the potential of the tested technology.

Acceptability Study of A3-K3 Robotic Architecture for a Neurorobotics Painting

2019

In this paper, authors present a novel architecture for controlling an industrial robot via Brain Computer Interface. The robot used is a Series 2000 KR 210-2. The robotic arm was fitted with DI drawing devices that clamp, hold and manipulate various artistic media like brushes, pencils, pens. User selected a high-level task, for instance a shape or movement, using a human machine interface and the translation in robot movement was entirely demanded to the Robot Control Architecture defining a plan to accomplish user's task. The architecture was composed by a Human Machine Interface based on P300 Brain Computer Interface and a robotic architecture composed by a deliberative layer and a reac…

Machine Learning Approaches for Activity Recognition and/or Activity Prediction in Locomotion Assistive Devices—A Systematic Review

2020

Locomotion assistive devices equipped with a microprocessor can potentially automatically adapt their behavior when the user is transitioning from one locomotion mode to another. Many developments in the field have come from machine learning driven controllers on locomotion assistive devices that recognize/predict the current locomotion mode or the upcoming one. This review synthesizes the machine learning algorithms designed to recognize or to predict a locomotion mode in order to automatically adapt the behavior of a locomotion assistive device. A systematic review was conducted on the Web of Science and MEDLINE databases (as well as in the retrieved papers) to identify articles published…

Tangibot: A collaborative multiplayer game for pediatric patients

2019

[EN] Background Previous research has studied the effects of games in pediatric wards, but none of it has focused on the impact of the hospital¿s school staff on the psychosocial state of the children nor on the gameplay itself. Objectives To present the Tangibot application and evaluate its impact on the children¿s psychosocial state in the short term and the impact of the teacher on their psychosocial state, communications and coordination during the activity. Methods A study was conducted in a hospital classroom with 20 participants, who participated twice in the game: one with the teacher playing along and another without her. An observational scale was used by two evaluators in order t…
