Vision-based hand pose estimation: A review

A gesture recognition method includes detecting multiple pointers in close proximity to a touch surface to determine if the multiple pointers are being used to perform a known gesture. When the multiple pointers are being used to perform a known gesture, executing a command associated with the gesture. A touch system incorporating the gesture recognition method is also provided.

A method is presented for robust tracking in highly cluttered environments. The method makes effective use of 3D depth sensing technology, resulting in illumination-invariant tracking. A few applications using tracking are presented including face tracking and hand tracking.

Visual Tracking Using Depth Data

A head mounted device provides an immersive virtual or augmented reality experience for viewing data and enabling collaboration among multiple users. Rendering images in a virtual or augmented reality system may include capturing an image and spatial data with a body mounted camera and sensor array, receiving an input indicating a first anchor surface, calculating parameters with respect to the body mounted camera and displaying a virtual object such that the virtual object appears anchored to the selected first anchor surface. Further operations may include receiving a second input indicating a second anchor surface within the captured image that is different from the first anchor surface, calculating parameters with respect to the second anchor surface and displaying the virtual object such that the virtual object appears anchored to the selected second anchor surface and moved from the first anchor surface.

We present a multi-PC/camera system that can perform 3D reconstruction and ellipsoid fitting of moving humans in real time. The system consists of five cameras. Each camera is connected to a PC which locally extracts the silhouettes of the moving person in the image captured by the camera. The five silhouette images are then sent, via local network, to a host computer to perform 3D voxel-based reconstruction by an algorithm called SPOT. Ellipsoids are then used to fit the reconstructed data. By using a simple and user-friendly interface, the user can display and observe, in real time and from any view-point, the 3D models of the moving human body. With a rate of higher than 15 frames per second, the system is able to capture non-intrusively, a sequence of human motions.

Real-time tracking of multiple fingertips and gesture recognition for augmented desk interface systems

PROBLEM TO BE SOLVED: To provide a man-machine interface system to use an image of a fingertip on a desk. SOLUTION: A processing to be performed by calculating a coordinate of the fingertip in a system 60 is explained. 1. An area of a user's hand placed on the desk 10 is extracted from the image of an infrared camera. 2. A fingertip point of a user is detected from the extracted hand area. 3. A position coordinate of the fingertip point on a camera image is transformed into a position coordinate on the desk by calibration by using a preliminarily calculated projective transformation parameter. 4. Interaction is taken with an object and information projected on the desk based on fingertip position information on the desk. COPYRIGHT: (C)2001,JPO

Man-machine interface system

PROBLEM TO BE SOLVED: To provide a driving evaluation system for evaluating driving in response to an actual situation, and to provide an on-vehicle machine and an information processing center. SOLUTION: An eco-driving probability density estimating section 231 and an eco-driving awareness pre-learning section 241 reset the evaluation reference of driving for the driver of own vehicle, with respect to the respective situations where own vehicle is driven, whenever driving is evaluated. Consequently, the evaluation reference of the driving is set, in response to the actual situation, when the evaluation is performed compared with a case where reference to evaluate the driving is uniformly set. Additionally, an eco-driving possibility degree/skill level estimating section 161 and an eco-driving awareness degree estimating section 171 evaluate the driving of the driver of the self vehicle, on the basis of the evaluation reference which is reset by the eco-driving probability density estimating section 231 and the eco-driving consciousness pre-learning section 241. Thus, driving is evaluated, in matching with the actual situation. COPYRIGHT: (C)2011,JPO&INPIT
