Learning traces from VR activities BB – Design Document

The "VR Traces" component is designed to capture, record and analyse user interactions with virtual reality (VR) exercises in educational and training contexts. Using the xAPI standard for data structuring, this system enables in-depth analysis of learners' behaviour, successes and difficulties within VR simulations. Key components include the generation of xAPI traces, integration with Learning Record Stores (LRS) for data storage, and analysis tools to interpret the data.Traces are decided by simulator's editor.

Input / Output Data

The sample xAPI traces represent a sequence of events in a fibre welding simulation by John Doe, capturing key moments: the beginning, the most significant interactions (classified by severity), and the end. Here is a detailed explanation of each trace, highlighting the exercise ID, the registration ID, and the object IDs to understand how these elements reconstruct Jean Dupont's learning scenario.

The first trace is the initialisation trace, which marks the start of the fibre welding exercise. It contains the following information:

registration is a unique identifier assigned to a specific instance of a learning activity or session. This identifier is used to group together all the interactions and events linked to that particular session, enabling consistent and contextualised analysis of the learning data. It can be used to correlate all the actions, decisions and results of a learner within the same learning session.

Summary of this trace is as follows: John Doe(Actor) started (Verb) a fibre welding exercise on 15 March 2024 ( timestamp). This exercise is part of the "Course fibre welding" ( parent) course. The exercise takes place on the "Discover" simulator (platform), in a virtual reality environment (category). A unique identifier (registration) is generated for this exercise, marking the start of this session and also serving as an anchor point for all John's future interactions and assessments within this simulation (Object id).

At the heart of the fibre welding exercise undertaken by Jean Dupont, a series of xAPI traces captures every key moment, enriching our understanding of how the exercise unfolded. Each trace is classified by its nature on the learning experience.
