“…Trace analysis models can consequently be designed to: (a) formalize and operationalized these needs and (b), monitor the evolution of the virtual artefact in the VLE. For instance, Toussaint et al (Toussaint et al, 2015) analysed the learner activity, in terms of action, during a simulated surgical operation. Heterogeneous traces made of some discrete positions and orientations of a trocar and, gaze direction on monitoring devices, were recorded to check if some ordered sequences of parallel actions were correctly performed.…”

“…The evaluation strategy requires, for the final users, to have well-established knowledge in mathematics, physics and bio-mechanics to correctly interpret the descriptor values. To tackle this issue, some trace analysis models can give an understandable meaning to the descriptors according to the application domain vocabulary (Toussaint et al, 2015;Baudouin et al, 2007). For instance, the well-known Laban Movement Analysis (LMA) (Laban and Ull-mann, 1988) was used by (Aristidou et al, 2015) to describe the motion according to its four dimensions (i.e.…”

“…Some VLEs evaluate the learner by detecting an actions sequence/pattern each action being composed of one or several gestures (Baudouin et al, 2007;Toussaint et al, 2015;Mahdi et al, 2019). However, their analysis are mainly based on the discrete states of the manipulated objects and not on the performed gestures.…”

This paper discusses the usability of a generic method for the evaluation of the user activity in Virtual Learning Environments (VLE) and its implementation with Unity. In the context of motion-based tasks, the learning process relies on the observation and imitation of the task demonstrated by the teacher. The learner task is compared to the teacher one in terms of: (a) motions shape of the user and the manipulated artefacts and (b), the sequential order of 3D checkpoints that the user must collide with. The integration of the evaluation system into any existing VLE rises challenges regarding the system architecture and the Human Computer Interface to set up the evaluation process. A usability test related to the design of this process is conducted for a pool shooting, a dart throwing and a letter writing simulation. The preliminary results show that: (i) the integration of an existing VLE into the evaluation system is feasible despite issues related to the interaction assets and (ii), all participants are satisfied by their designed evaluation process for pool shooting and dart throwing, they were unable to set up a satisfying evaluation for letter writing due to scale issues.
