Description: The mental model in the context of virtual reality (VR) refers to the internal representation that a user has of how a VR system works. This representation is formed from previous experiences, knowledge, and expectations, and plays a crucial role in how users interact with virtual environments. Mental models allow users to anticipate outcomes, understand interactions, and navigate more effectively in complex environments. For example, a user who has engaged with immersive digital experiences may have a more developed mental model of how to move and act in a VR environment, facilitating their immersion and enjoyment. The accuracy of a mental model can influence the effectiveness of the VR experience, as an incorrect model may lead to frustrations or misunderstandings about the system’s capabilities. Therefore, designing VR experiences that align user expectations with the reality of the system is essential for improving usability and user satisfaction. In summary, the mental model is an essential cognitive tool that affects user interaction with virtual reality, largely determining the quality of the immersive experience.
