abstract = {A system for remote tactile telepresence wherein an array of predefined touch gestures are abstracted into cataloged values and invoked either by pattern matching, by assigned name or visual indicia. A local and remote cache of the catalog reduces latency even for complicated gestures as only a gesture identifier needs to be transmitted to a haptic output destination. Additional embodiments translate gestures to different haptic device affordances. Tactile telepresence sessions are time-coded along with audiovisual content wherein playback is heard, seen, and felt. Another embodiment associates motion capture associated with the tactile profile so that remote, haptic recipients may see renderings of objects (e.g., hands) imparting vibrotactile sensations.},

abstract = {This invention relates to tracking of user-worn and hand-held devices with respect to each other, in circumstances where there are two or more users interacting in the same share space. It extends conventional global and body-relative approaches to "cooperatively" estimate the relative poses between all useful combinations of user-worn tracked devices such as HMDs and hand-held controllers worn (or held) by multiple users. For example, a first user's HMD estimates its absolute global pose in the coordinate frame associated with the externally-mounted devices, as well as its relative pose with respect to all other HMDs, hand-held controllers, and other user held/worn tracked devices in the environment. In this way, all HMDs (or as many as appropriate) are tracked with respect to each other, all HMDs are tracked with respect to all hand-held controllers, and all hand-held controllers are tracked with respect to all other hand-held controllers.},

Methods, systems, and computer readable media for shader lamps-based avatars of real and virtual people are disclosed. According to one method, shader lamps-based avatars of real and virtual objects are displayed on physical target objects. The method includes obtaining visual information of a source object and generating at least a first data set of pixels representing a texture image of the source object. At least one of a size, shape, position, and orientation of a 3D physical target object are determined. A set of coordinate data associated with various locations on the surface of the target object are also determined. The visual information is mapped to the physical target object. Mapping includes defining a relationship between the first and second sets of data, wherein each element of the first set is related to each element of the second set. The mapped visual information is displayed on the physical target object using a display module, such as one or more projectors located at various positions around the target object.
