Problems solved by technology

[0011] Despite the existence of such synchronization means, it often happens that images that have to be displayed simultaneously on different (but adjacent) screens are actually displayed with a slight offset
These deviations, caused by synchronization problems between graphics cards and / or failure of at least one display unit, lead to "breaks" in each overall image observed by the immersive user, which disrupts the user's sense of immersion and thus their experience , can also cause discomfort

Embodiment Construction

[0039] In particular, the invention aims at proposing an analysis device DA for performing an analysis in a system SI comprising at least two display paths in order to determine whether these two display paths are synchronized and, optionally, to identify in the negative Which elements are not synchronized.

[0040] It should be understood that the "display path" here refers to a group of elements including, inter alia, the graphics card CGj and the display devices PIj, EAj.

[0041] By way of non-limiting example, system S1 is considered hereinafter to be an immersive virtual reality system for immersing a user in a virtual environment representing at least a part of a vehicle, optionally a motor vehicle type (such as an automobile) . However, the invention is not limited to this type of system, and thus not limited to the virtual environments described above. In fact, the invention relates to all systems comprising at least two image display paths, wherein it is sought to ...

Abstract

A device (DA) for analyzing a system (SI) comprising display means (PI1, EA1; PI2, EA2) responsible for displaying images, graphics cards (CG1, CG2) responsible for defining said images, and synchronization means (MS) for synchronizing the times of identical image definition by the graphics cards (CG1, CG2). This device (DA) comprises sensors (C1, C2) associated with display means (PI1, EA1; PI2,EA2) and generating a main signal representing a new image in case of detection of the display of one such new image by the associated display means, and analysis means (MA) responsible for determining a first time of reception of each of the main signals, then, when the first times of reception determined are representative of a same new image, determining a first time difference between said first times of reception determined.

Description

technical field [0001] The invention relates to a system comprising at least two independent display paths. Background technique [0002] A "display path" here refers to a set of elements including, inter alia, a graphics card and a display device. [0003] Some systems, such as but not limited to immersive virtual reality systems, include at least two display paths that are distinct and responsible for displaying images simultaneously. [0004] It will be appreciated that immersive virtual reality systems are utilized to immerse a user in a virtual environment, for professional or recreational purposes. This is especially true, though not exclusively, in the field of vehicles, especially of the motor vehicle type. For example, such immersion can be used to teach a user to change position in a particular environment, take advantage of objects or functions present in a particular environment, analyze user behavior in a particular environment, or observe a particular environ...
