SpatialProto: Using Real-World Captures for Rapid Prototyping of Mixed Reality Experiences
In CHI â21: Proceedings of the 2021CHI Conference on Human Factors in Computing Systems. May 03, 2021. Association for Computing Machinery, New York, NY, USA. (bib)

Spatial computing systems that blend virtual and real worlds are increasingly becoming ubiquitous. However, creating experiences for spatial computing is difficult and requires skills in programming and 3D content creation, rendering them inaccessible to a wide user-group. We present SpatialProto, an in-situ spatial prototyping system that lowers the barrier for users to engage in spatial prototyping. With a depth-sensing capable Mixed Reality headset, SpatialProto lets users record animated objects of thereal-world environment (e.g. paper, clay, people or any other prop), extract only the relevant parts, and directly place and transform these recordings in their physical environment. We describe the design and implementation of SpatialProto, a user study evaluating the system's prototype with non-expert users (n=9), and demonstrate applications where multiple captures are fused for compelling Mixed Reality experiences.
