3D modelling using Leap Motion - Focusing on homogeneous transforms
MetadataVis full innførsel
In this project, an implementation of an interactive application that focus on how to do homogeneous transformations using Leap Motion as the interaction interface have been made. A literature study was conducted in the start of the project to get an idea of what had already been done, and to get ideas on how to implement the software in this project. An evaluation process guided by the DECIDE framework and the GQM model was used in order to evaluate the project. After implementing a prototype, a pilot test was followed by an extensive user test after improving the prototype. The results from the user test have been quantified, and it was discovered that none of the rotation techniques are suitable for working with for longer periods of time. It also takes too long time to complete a rotation with the strategies implemented in this project compared to a how fast a user is able to rotate objects using a computer mouse. Even though the suggested techniques for rotating and translating objects did not prove to be easy, it is still worth noting that the techniques might be more useful for making freeform 3D models with a more creative touch where precision is not important. Leap Motion is still being developed, and motion tracking is not yet applicable for replacing mouse and keyboard for accurate 3D transforms. This research might give insight to others who want to explore tracking devices and 3D modeling, and understand how tracking devices may be used more easily for users.
