Publication number: 20220196840Abstract: Detecting material properties such reflectivity, true color and other properties of surfaces in a real world environment is described in various examples using a single hand-held device. For example, the detected material properties are calculated using a photometric stereo system which exploits known relationships between lighting conditions, surface normals, true color and image intensity. In examples, a user moves around in an environment capturing color images of surfaces in the scene from different orientations under known lighting conditions. In various examples, surfaces normals of patches of surfaces are calculated using the captured data to enable fine detail such as human hair, netting, textured surfaces to be modeled. In examples, the modeled data is used to render images depicting the scene with realism or to superimpose virtual graphics on the real world in a realistic manner.Type: ApplicationFiled: December 29, 2021Publication date: June 23, 2022Inventors: Otmar HILLIGES, Malte Hanno WEISS, Shahram IZADI, David KIM, Carsten Curt Eckard ROTHER

Publication number: 20170199580Abstract: An augmented reality system which enables grasping of virtual objects is described such as to stack virtual cubes or to manipulate virtual objects in other ways. In various embodiments a user's hand or another real object is tracked in an augmented reality environment. In examples, the shape of the tracked real object is approximated using at least two different types of particles and the virtual objects are updated according to simulated forces exerted between the augmented reality environment and at least some of the particles. In various embodiments 3D positions of a first one of the types of particles, kinematic particles, are updated according to the tracked real object; and passive particles move with linked kinematic particles without penetrating virtual objects. In some examples a real-time optic flow process is used to track motion of the real object.Type: ApplicationFiled: January 24, 2017Publication date: July 13, 2017Inventors: Otmar Hilliges, David Kim, Shahram Izadi, Malte Hanno Weiss
