HoverCam: interactive 3D navigation for proximal object inspection

Abstract: We describe a new interaction technique, called HoverCam, for navigating around 3D objects at close proximity. When a user is closely inspecting an object, the camera motions needed to move across its surface can become complex. For tasks such as 3D painting or modeling small detail features, users will often try to keep the camera a small distance above the surface. To achieve this automatically, HoverCam intelligently integrates tumbling, panning, and zooming camera controls into a single operation. This allows the user to focus on the task at hand instead of continuously managing the camera position and orientation. In this paper we show unique affordances of the technique and define the behavior and implementation of HoverCam. We also show how the technique can be used for navigating about data sets without well-defined surfaces such as point clouds and curves in space.

Camera controlling device and method for predicted viewing

Abstract: A personal computer detects the current state of a video camera with reference to setting information transmitted thereto from a work station. When a command for controlling the video camera is inputted from a mouse, the personal computer predicts an image, which is assumed to be shot by the video camera upon execution of the command, with reference to both the information transmitted from the work station and the command inputted from the mouse, and then displays the predicted image on a CRT monitor. Referring to the image being displayed on the CRT monitor, a user performs a manipulation to instruct execution of the command in the case of executing the previous input command. As a result, the command inputted previously is transmitted to the work station via an internet, thereby controlling the video camera and a pan tilter. Thus, the video camera connected via a network or the like can be controlled smoothly.

Video processing systems and methods

Abstract: A smart camera system is disclosed. The camera can work with cloud data storage systems and compute cloud. A call center can access the cloud to provide security monitoring services.

A Camera Engine for Computer Games: Managing the Trade‐Off Between Constraint Satisfaction and Frame Coherence

Abstract: Many computer games treat the user in the “1st person” and bind the camera to his or her view. More sophistication in a game can be achieved by enabling the camera to leave the users' viewpoint. This, however, requires new methods for automatic, dynamic camera control. In this paper we present methods and tools for such camera control. We emphasize guiding camera control by constraints; however, optimal constraint satisfaction tends to lead to the camera jumping around too much. Thus, we pay particular attention to a trade-off between constraint satisfaction and frame coherence. We present a new algorithm for dynamic consideration of the visibility of objects which are deemed to be important in a given game context.

Aging in place: fall detection and localization in a distributed smart camera network

Abstract: This paper presents the design, implementation and evaluation of a distributed network of smart cameras whose function is to detect and localize falls, an important application in elderly living environments. A network of overlapping smart cameras uses a decentralized procedure for computing inter-image homographies that allows the location of a fall to be reported in 2D world coordinates by calibrating only one camera. Also, we propose a joint routing and homography transformation scheme for multi-hop localization that yields localization errors of less than 2 feet using very low resolution images. Our goal is to demonstrate that such a distributed low-power system can perform adequately in this and related applications. A prototype implementation is given for low-power Agilent/UCLA Cyclops cameras running on the Crossbow MICAz platform. We demonstrate the effectiveness of the fall detection as well as the precision of the localization using a simulation of our sample implementation.
