ABSTRACT
The work aimed to develop a method for evaluating objects in real or virtual environment. It should specify the relevant evaluation dimensions depending on the environment (REAL or VIRTUAL) and task that can be performed (I DO an action, or I WATCH an action). These conditions can have an impact on the mental representation of the object, since they may involve a different perspective taking and spatial reference. A first study highlights that participants produced larger task verbalization (describe an object or simulate its use) in virtual context that in real context, and a second study showed that an observer evaluates the usability of objects more favorably than an actor.

Effects on User Experience in an Edutainment Virtual Environment: Comparison Between CAVE and HMD
ECCE '17: Proceedings of the European Conference on Cognitive ErgonomicsThe user experience in immersive virtual environment can be broadly defined by the feeling of presence and immersion in a virtual environment. The propensity of feeling "there" and "enveloped by" in the virtual environment seems to be essential in ...
