Evaluating landmark attraction model in collaborative wayfinding in virtual learning environments

ABSTRACT

In Virtual Learning Environments efficient navigation is a major issue, especially when it is used as a component in the learning process. This paper addresses the challenges in creating meaningful navigation routes from language learning perspective. The work is grounded on findings from a specific case on German language learning, wherein two remotely located users communicated in a wayfinding guidance scenario. The users navigated through 360-degree virtual panoramic images using body gestures and could receive communication help via spoken hints by pointing at objects in the scenery. An important design consideration is how to choose these objects, as they have both navigational importance and pedagogical significance in terms of learning the desired language. Wayfinding interactions from 21 participants were compared to the values provided by a landmark attraction model applied on the landmarks along the routes. The results show that there was a clear connection between prominence of landmarks and time spent on each panorama. This indicates that together with pedagogical planning, the model can aid in selecting the interactive content for language learning applications in virtual environments.
