Summary
This paper introduces a methodological categorisation of tasks and techniques for the design of 360° immersive video applications. Following the design approach presented, a testbed application has been created as an immersive interactive virtual tour at the historical centre of the city of Rethymno in Crete, Greece, which has undergone user trials. Based on the analysis of the results of this study, a set of design guidelines for the implementation of 360° immersive video virtual tours is proposed.

Innovative VR tools and techniques
Three hundred sixty–degree (360°) immersive video applications for Head Mounted Display (HMD).

VR in education
The experience had been designed as a gamified, educational tour, revealing information about the city in a fun and engaging way.
An evaluation of the educational potential and level of engagement offered through the gamification of a Cultural Heritage storytelling experience using the 360° video medium is conducted.
