T1.1 – Definition of User Requirements (M1-M6, TETRAGON: 6 PM; EKETA: 2 PM, D1.1):
This subsection includes tasks aimed at the precise analysis of the needs of a trade fair within virtual reality. Initially, the platform’s user categories will be analyzed, e.g., organizers (e.g., TETRAGON), exhibitors (TETRAGON’s clients), and the public (visitors). A use case scenario will be drafted for each stakeholder in order to elicit the required platform functionalities that will render it a complete software solution for conducting exhibitions in virtual reality. For instance, organizers and exhibitors must be able to modify the booth composition via WPUnity to avoid communication misunderstandings that increase construction costs. Furthermore, the visit to a booth should be extended through the capabilities offered by virtual reality so that visitors receive enriched information, e.g., through teleportation to other spaces such as a factory, showroom, store, etc. A clear distinction will be made regarding how platform services are offered: a) via web pages (e.g., visitor registration, presentation of detailed statistics), b) via 3D virtual reality (e.g., navigation within the booth and conversation with sales staff), and c) via video calls (e.g., private conversation). Security safeguards will be defined clearly for the protection of personal data, e.g., visitor anonymity in usage statistics, if desired.
T1.2 – Technical Requirements and Platform Architectural Design (M1-M6, EKETA: 4 PM; TETRAGON: 2 PM, D1.2):
These tasks involve defining the services and technologies capable of covering user needs. A technological assessment of the required technologies will be performed regarding the project budget to ensure the platform is implemented on time. The platform architecture will be designed using a bottom-up approach, e.g., by creating a diagram connecting services with software. Open-source software will be selected to support the simultaneous immersion of multiple players in a virtual space. One such software is Mozilla Hubs, which also supports private conversations (Peer-to-peer) without data being stored on an intermediate server [Mozilla Hubs]. The type of upgrades required for EKETA’s WPUnity software will be studied to cover the user needs as mentioned in T1.1.
Roles:
TETRAGON will coordinate this WP, as it possesses experience in designing physical exhibitions and has a broad client base of exhibitors. EKETA will define the technical requirements for satisfying the platform’s user requirements and the platform’s architectural design.
