Steerable augmented reality with the beamatron

Abstract: Steerable displays use a motorized platform to orient a projector to display graphics at any point in the room. Often a camera is included to recognize markers and other objects, as well as user gestures in the display volume. Such systems can be used to superimpose graphics onto the real world, and so are useful in a number of augmented reality and ubiquitous computing scenarios. We contribute the Beamatron, which advances steerable displays by drawing on recent progress in depth camera-based interactions. The Beamatron consists of a computer-controlled pan and tilt platform on which is mounted a projector and Microsoft Kinect sensor. While much previous work with steerable displays deals primarily with projecting corrected graphics onto a discrete set of static planes, we describe computational techniques that enable reasoning in 3D using live depth data. We show two example applications that are enabled by the unique capabilities of the Beamatron: an augmented reality game in which a player can drive a virtual toy car around a room, and a ubiquitous computing demo that uses speech and gesture to move projected graphics throughout the room.

Augmented reality device, system, and method for safety

Abstract: Disclosed is a device, system, and method utilizing augmented-reality (AR) for safety. The AR safety system generates hazard-response messages in response to sensor data in order to help users understand and response to hazards in work environments in an intuitive and effective way. The AR safety system fuses a plurality of technologies. These technologies include person location/tracking, hazard detection/tracking, and augmented reality (i.e., AR).

Disposal of explosive ordnances by use of a bimanual haptic telepresence system

Abstract: The paper outlines a novel approach for performing explosive ordnance disposal by use of a bimanual haptic telepresence system. This system enables an operator to perceive multimodal feedback from a remote environment for proper task execution. The developed experimental setup, comprising a bimanual human system interface and the corresponding bimanual teleoperator for use of both hands, is presented in detail. The teleoperation control architecture is discussed as well as a local model-based impedance control algorithm for manipulator control. Human-system performance is improved by means of stereo visualization of the tele-environment together with overlayed Augmented Reality assistance, and an algorithm for avoidance of dangerous manipulator configurations supported by augmented force feedback. Furthermore, a recently developed UDP communication library is presented for system interconnection taking into account compression of haptic data. Thus efficient and low delay of data transfer is ensured. The usability and effectiveness of the developed bimanual telepresence system are demonstrated by focusing a relevant task scenario, such as demining operations in a remote environment.

Systems and methods for presenting building information

Abstract: Described herein are systems and methods for presenting building information. In overview, the technologies described herein provide relationships between Building Information Modeling (BIM) data (which includes building schematics defined in terms of standardized three dimensional models) and Building Management System (BMS) data (which includes data indicative of the operation of building components such as HVAC components and the like). Some embodiments use relationships between these forms of data thereby to assist technicians in identifying the physical location of particular pieces of equipment, for example in the context of performing inspections and/or maintenance. In some cases this includes the provision of 2D and/or 3D maps to portable devices, these maps including the location of equipment defined both in BIM and BMS data. In some cases, augmented reality technology is applied thereby to provide richer access to positional information.
