Touching the Cloud is a bi-manual user interface for the interaction with, selection and annotation of immersive point cloud data. With minimal instrumentation, the setup allows users in an immersive head-mounted display environment to naturally interact with point clouds. By tracking the user's hands using an OpenNI sensor and displaying them in the virtual environment, the user can touch the virtual 3D point cloud in mid-air and transform it with pinch gestures. In addition, by triggering voice- or button-press-activated commands, the user can select, segment and annotate the immersive point cloud, thereby creating hierarchical exploded view models.
