Extended Reality Sign Translating Platform (XR-STP)

The Functional Analysis stage involves breaking down the system into its functional components and specifying detailed functional requirements, ensuring that all necessary features and functions are thoroughly documented and understood. This phase provides four main types of requirements: (i) Functional Requirements: These are detailed descriptions of each feature and function of the XR-STP, organized by use cases or scenarios. For each phase of the lifecycle, we provide an inventory of main functions (Fm) and constraint functions (Fc), validate them, and characterize them by specifying criteria for function appreciation, their levels (expected performance), flexibility of each criteria level, and acceptance limits (la limite d’acceptabilité). These include functionalities like real-time translation of sign languages, integration with existing systems, and data conversion capabilities. (ii) External Interface Requirements: These specifications cover user interfaces, hardware interfaces, software interfaces, and communication protocols, ensuring seamless interaction between the XR-STP and other systems or devices. Additionally, this phase addresses (iii) System Features: Detailed explanations of each system feature, including inputs, processing, and outputs, and (iv) Non-Functional Requirements: Requirements related to performance, security, usability, reliability, and maintainability. This comprehensive Functional Analysis phase culminates in the creation of the Functional Specifications Document, which defines the functional specifications for the XR-STP.
