Anymaker AR - Augmented reality as a mean to improve 3D sketching in digital space

University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

Abstract: Digital three-dimensional sketching and modeling is a field in computer science that is constantly evolving through new interaction paradigms. Many solutions move away from the traditional modern modeling software and aim to create a more natural and intuitive user experience. This report aims to compare an existing touch-screen solution against a novel implementation using augmented reality, that is made to replicate the way we draw in real life. A comparative task-based user study was performed and objective data was gathered together with a questionnaire and survey. Results indicate that subjects worked faster and preferred certain models when using the existing technology, while using the new implementation reached better or equal results in terms of spatial cognitive abilities, the frequency at which the user needed to redo their work, and wanted to reuse the software. Augmented reality showed good results when creating the simpler geometric shape of pyramids but comparatively worse results for objects of less uniform shapes. With further improvement, augmented reality can be seen as a good mean to improve the way we sketch and model in three di-mensions.
