Virtual stage sets in live performing arts (from the spectator to the spect-actor)

This paper studies the added value of VR to the art of stage setting through examples and experiments. It will also analyze the link between the audience and digital sets (VR, AR), from an aesthetic point of view as well as a practical one. It is important for us to succeed in creating a theatrical set which favors the spectator's presence for him to become a live performing spectator, and thus have a stronger link with the setting in the short as well as long run

Application of evolution's laws

Technical systems evolution follow trends, some laws describe the different steps of evolution of those systems. These laws are known as "laws of technical systems evolution" from the TRIZ theory. The aim of this paper is to propose an approach facilitating the use of the evolution laws, as part of a framework for innovation. To achieve our goal we start by an analysis of each definition of the three first evolution laws. It’s analysis we’ll permit to extract with precision part of the definition we’ll use to construct a model helping the use of the laws. The model we propose is composed of a short quiz that users must answer. The purpose of these questions is to guide the user as far as possible in the identification of functional elements of the system and possible developments of innovative products, as recommended by the three first laws. After that, we’ll conduct an experimentation to taste this model on two kinds of participants, some of them are software developers working in differents companies, they do not know the TRIZ theory. The other participants are students in training who learned some tools to innovate, they are not completely novices on TRIZ. To conclude, we’ll present the relevance of our approach to use systematically the first 3 evolution laws of TRIZ

Designing for the Ubiquitous Computing era: towards the reinvention of everyday objects and the creation of new user experiences

Researchers of the Ubiquitous Computing community (Ubicomp) have been pursuing the vision of a world where technologies and services permeates every object of our lives for years. With components getting smaller, cheaper and more powerful, it has become possible to manufacture connected objects capable of interacting with resources of the World Wide Web. This opens up the possibility for researchers and practitioners to consider information as a design material and objects as platforms for services. By allowing users to personalize, complement or repurpose the functions of their objects, such services have a great impact on the way artifacts are designed. Designing for the Ubiquitous Era requires modifying our practice and reinforcing collaboration between disciplines at every steps of the creation process. In this article, we discuss the need to reinvent objects and to investigate the tools supporting the creation of rich services’ experiences

A mixed-integer heuristic for the structural optimization of a cruise ship

peer reviewedA heuristic approach is proposed to solve the structural optimization problem of a cruise ship. The challenge of optimization is to define the scantling of the structure of a ship in order to minimize the weight or the production cost. The variables are the dimensions and positions of the constitutive elements of the structure: they are discrete by nature. The objective functions are nonlinear functions. The structure is submitted to geometric constraints and to structural constraints. The geometric constraints are linear functions and the structural constraints are implicit functions requiring a high computation cost. The problem belongs to the class of mixed-integer nonlinear problems (MINLP). A local heuristic of the type “dive and fix” is combined with a solver based on approximation methods. The solver is used as a black-box tool to perform the structural analysis and solve the nonlinear optimization problems (NLP) defined by the heuristic. The heuristic is designed to always provide a discrete feasible solution. Experiments on a real-size structure demonstrate that the optimal value of the mixed-integer problem is of the same magnitude as the optimal value of the optimization problem for which all the variables can take continuous values
