Estelle Guerry, postgraduate student at the University of Toulouse. She holds a master focused on creation, research and colour innovation in 2017 from Institute Colour Image Design (ISCID, Toulouse University, France).She specializes in design-colour and lighting science, with the aim of promoting the comfort and well-being of the elderly. She provides her expertise in the field of research and the socio-economic environment

Georges Zissis, Prof., Vice-Rector Toulouse 3 University for International Projects & Cooperation, has been graduated in 1986 from Physics department of University of Crete in general physics. He got his M. Sc. and Ph.D. in Plasma Science in 1987 and 1990 from Toulouse 3 University (France). He is today Distinguish-class Professor in Toulouse 3 University. His primary area of work is in the field of Science and Technology Lighting Systems. He won in 2006 the 1st Award of the International Electrotechnics Committee Centenary Challenge for his work on standardisation for street lighting systems and in 2009 the Energy Globe Award for France. In 2011 he has been awarded the title of Doctor Honoris Causa of Saint Petersburg State University (Russian Federation). He was President of IEEE Industrial Applications Society. Today, he is Chairman of IEEE Smart Cities Program and he is chairing the 4E-Solid State Lighting Annex of International Energy Agency

Céline Caumon, Arts & Design, Ph.D. At present, she is the full professor at the University of Toulouse-Jean Jaurès. At the initiative of the creation of the Institute Colour Image Design (ISCID) and training in Creation Research and Innovation, she participates in the development of colour-design in other scientific disciplines and in the socio-economic world, member of various boards and commissions (valorization, SHS innovation, design) at local and national level, she develops international projects, more particularly in China where she is welcomed as a visiting professor at the University of Suzhou , Arts and Crafts Research Institute, Research Centre, SUDA School of Art. She is the author of “Cahier de Tendances, Chromatic Design”, “Action Research through Artistic Creation” and is currently finishing a book on the characterization of colour design and the definition of project methodologies in colouring

Laurent Canale, Dr., CNRS Research Engineer. He holds a Master and Ph.D. focusing on High Frequencies Electronics and Optoelectronics from Sciences Department of Limoges University, obtained in 1998 and 2002. In 2010, he joined the National Center for Scientific Research (CNRS) and he works in LAPLACE Lab., “Light & Matter” research group, focused on efficient light sources as LED and OLED (SSL) with special interest in aging degradation mechanisms with photometrical, electrical and structural characterizations. He published over 120 articles dealing with artificial light sources, from the harmonic impact on the electrical grid to the human eye perception, the photosynthesis, the light pollution and artificial light applications including 5G or WiMax antennas embedded in OLED. He leads the French Illuminating Engineering Association as Midi-Pyrenees region Chairman since 2014 and the “Industry Lighting and Display Committee” from IEEE (IEEE IAS ILDC) as Vice-Chair since 2020

Elodie Bécheras, Associate Professor in applied arts and design, co-head of the Higher Institute Colour Image Design (ISCID, Lab. Lara-Seppia, Toulouse University, France) and independent scenographer. Her creative and research work focuses on two fields of study: the creative practices related to light, from the point of view of colour, city, landscape and scenography; the food practices and culinary design, especially in a sensory approach. At the crossroads of the first two, another line of research questions the emergence modalitites of the ambience through an inter-sensory perspective

In the context of an aging population, it is important today to take into account the needs of our seniors, to help them better live their aging. The design of colour and lighting ambiance contributes in the practice of their daily activities in their living environment. This study postulates a protocol of good practices in terms of colour and lighting to design a visual environment adapted to the needs of these users. The protocol is based on a combination of chromatic and lighting expertise. Chromatic colour matching based on Natural Colour System tools is combined with a photometric survey to characterize the visual environment. These data make it possible to establish a protocol used to design new chromatic ranges applied to new environments or to evaluate the applicability of the existing ranges.
