Interaction Principles of 3D World Editors in Mobile Phones with Focus on the User Experience

Sammanfattning: 3D world editors are widely used in mobile applications for manipulation of the virtual world, however, there are no frameworks of design regarding the best practice interaction principles for 3D world editors on mobile phones. By looking at methods, concepts, and functions used in general consumer world editors, this research focused on the development and design of a prototype, which was then used to evaluate the interactions principles divided in the following use cases: selection, placement and manipulation. The results from a heuristic evaluation backed up by user evaluations proved that there is in fact a majority that prefers the following combination of interaction principles in terms of user experience: an organized and simplified shop interface for selection, grid-system over the free-system for placement of virtual objects, and a combination of tap and hold to manipulate virtual objects for the 3D world editor prototype for mobile phones created in this research.
