A virtual reality interface for interactions with spatiotemporal 3d data

Abstract

Traditional interfaces for interacting with 3D models in virtual environments lack support for spatiotemporal 3D models such as point clouds and meshes generated by markerless capture systems. We present a virtual reality (VR) interface that enables the user to perform spatial and temporal interactions with spatiotemporal 3D models. To accommodate the high volume of spatiotemporal data, we provide a data format for spatiotemporal 3D models which has an average speedup of 3.84 and a space reduction of 43.9% over traditional model file formats. We enable the user to manipulate spatiotemporal 3D data using gestures intuitive from real-world experience or by using a VR user interface similar to traditional 2D visual interactions.
