The BlueLemon virtual immersion room has been installed at the institute’s Chalon-sur-Saône campus. This facility supports training, design project reviews, and research on perception in immersive environments.
The Blue Lemon is a cube with sides measuring approximately 3 meters, capable of projecting stereoscopic images onto five surfaces (including the floor and ceiling). It is one of the few systems in France that offers a high-quality virtual immersion experience.
A delayed installation due to building constraints
When the institute in Chalon-sur-Saône moved, the relocation of BlueLemon required special preparation. The floor of the new building had to be modified to accommodate the equipment used to transport the various components. This requirement delayed the move.
A Tool for Training
BlueLemon is currently used during design project reviews. The system is also available to students, allowing them to experience a large-scale immersive environment—something that is still relatively uncommon in educational programs. This addition complements the use of virtual reality headsets and provides access to another form of immersion and interaction.
Support for Research
BlueLemon is also used for research, particularly at the doctoral level. The research focuses on human perception in this type of immersive system and on comparisons with more traditional applications, such as virtual reality headsets. These studies build on the themes that have long been explored in Chalon-sur-Saône regarding virtual environments, user experience, and industrial applications.
A piece of equipment that is part of the institute's history
BlueLemon serves as a showcase for the institute. In particular, it can be used as a prototyping tool for devices tailored to industrial needs, especially for small and medium-sized enterprises (SMEs) that require a device whose design will be validated using BlueLemon.
About BlueLemon
BlueLemon was acquired thanks to significant support from the European Union (ERDF funds), the French government (through the CPER),the Bourgogne-Franche-Comté Region, the UiMM (through the F2i fund), Grand Chalon, and the Carnot ARTS Institute. This virtual immersion room, provided by Antycip, is a cube approximately 3 m on each side with stereoscopic images rear-projected onto five surfaces (including the floor and ceiling).
Each projected pixel measures approximately 1.2 mm (very close to human visual resolution under normal viewing conditions), the maximum luminance is approximately 25,000 lumens, and the contrast ratio is approximately 2,000:1 in active stereoscopic mode, ensuring excellent viewing conditions.
A cluster of computers enables real-time image processing. A spatial audio system adds a sound dimension to the interactive visualization. The active stereoscopic system can be decoupled to provide a virtual immersion experience for two users collaborating in the virtual environment, each with their own dedicated viewpoint.
BlueLemon was used in collaboration with Renault through the joint LiV laboratory, which was active until 2021.
