THEIA-XR: Use Case Specification (D2.1)

In this project, use cases are defined as descriptions of how a person who uses a process, or a system will accomplish an objective. These use cases outline a system’s behaviour from a user’s point of view as it responds to a request and is represented as a sequence of steps. In this document, the work performed so far in Task 2.1 will be summarized. It will present the first versions of the use case specifications. At the first stage, the use cases are described are they currently are with the existing machines used within the demonstrations. In the second sage, XR extensions are identified that will be added/investigated for the solutions and how they would be added to the identified use cases and their scenarios. This will then demonstrate how the different situations unfold with the aid of XR interaction. The three different use cases (snow grooming, logistics and construction) defined within the THEIA-XR project are introduced and described in detail in this document. For each use case, a dedicated chapter (Section 0 to Section 5) within the deliverable is available. There we also describing the utilization of user stories to describe especially operator's role in the process. User Stories are centred on the result and the benefit of the thing you're describing, whereas Use Cases can be more granular, and describe how your system will act. We also listed potential issues which we found during this phase. In section 4 we are concluding results of this deliverable. This document provides a solid basis to accomplish the proper requirement specification and technical analysis of the applications investigated during the duration of the project. A second, and final, updated version of this deliverable is due in Month 19 of the project and will include the final definition of the use cases. This will be based on the experiences gained and developments performed within the first half of the project.
