Exploring gestural input for engineering surveys of real-life structures in virtual reality using photogrammetric 3D models

Abstract Photogrammetry is a promising set of methods for generating photorealistic 3D models physical objects and structures. Such may rely solely on camera-captured photographs or include additional sensor data. Digital twins are digital replicas an opportune approach the purpose preparing twins. At sufficiently high level quality, provide effective archival representations structures become substitutes engineering inspections surveying. While photogrammetric techniques well-established, insights about interacting with such in virtual reality remain underexplored. We report results qualitative case study which we asked six domain experts to carry out measurement tasks immersive environment using bimanual gestural input coupled gaze-tracking. The revealed that gaze-supported interaction modality experts. It allows efficiently manipulate measure elements model. To better allow designers support this modality, design implications distilled from feedback
