Interaction peripheral device capable of controlling an element for touching and grasping multidimensional virtual objects
2015
An interaction peripheral device capable of controlling an element for touching and grasping multidimensional virtual objects, including at least two interaction modules, each interaction module being intended to be actuated by a finger of an operator and including a control sensor allowing control of displacement, according to a predetermined number of degrees of freedom, of a portion of the element for touching and grasping virtual objects by bending/extending and/or adduction/abduction displacement of the finger of the operator, and a vibrator able to emit a vibration upon touching and/or letting go of a virtual object by a portion of said element for touching and grasping virtual object…

Scheduling independent stochastic tasks on heterogeneous cloud platforms
2019
International audience; This work introduces scheduling strategies to maximize the expected number of independent tasks that can be executed on a cloud platform within a given budget and under a deadline constraint. The cloud platform is composed of several types of virtual machines (VMs), where each type has a unitexecution cost that depends upon its characteristics. The amount of budget spent during the execution of a task on a given VM is the product of its execution length by the unit execution cost of that VM. The execution lengths of tasks follow a variety of standard probability distributions (exponential, uniform, halfnormal, etc.), which is known beforehand and whose mean and stand…
Enhancing the National Identity through Historic Buildings Conservation using VR Technology
2011
The event organized by TOTAL, Indonesian Embassy in France, etc.; International audience; Indonesia comprises the most extraordinary collections of cultural heritage within various historical places. Those heritage sites in all over Indonesia longingly present its own spirit of place, genius loci, as perform on its unique artifacts, and the community's cultural resources. The legacy of Indonesian collective past such as the built environment, artifacts, shrines and temples, buildings and monuments, sites and districts from the village to the center city are some significant heritages that very important for our national identity. Unfortunately, many heritage objects have been neglected towa…

Comparison of immersive room and virtual reality, through the consumption episode "Eating a sandwich in a park"
2020
International audience; Conventional approaches for consumers’ tests, CLT and HUT, lead respectively to a high either internal or external validity. In recent years, several immersive approaches have been developed to achieve both internal and external validity at the same time, i.e. environments close to actual consumption context while keeping parameters under control. Virtual reality (VR) is one of the most promising one.In this study, we assess two immersive strategies in terms of internal and external validity for a consumption episode “having a sandwich for lunch in a park”. The two experimental conditions were an immersive room (N = 57, Fig. 1) and a VR environment (N = 55, Fig. 2). …
Comparison of sensory visual properties of food products in real and virtual conditions
2018
International audience; As Virtual Reality usages expand, as professional tools in one hand and as gaming devices in another hand, the use of these technologies for consumer science and sensory science is more and more interesting to be investigated. Before using Virtual Reality to evaluate new products, it seems necessary to check the similarities and differences of the visual attributes of products in real and in virtual. All the experiments were conducted with Unity software and HTC Vive Helmet. First, we designed virtual sensory booths, similar to the booths of AgroParisTech sensory Lab. Then, we choose a set of real products (cookies from the market) and digitalize them. At last, virtu…
