Abstract: Apparatus and methods for extraction and calculation of multi-person performance metrics in a three-dimensional space. An example apparatus includes a detector to identify a first subject in a first image captured by a first image capture device based on a first set of two-dimensional kinematic keypoints in the first image, the two-dimensional kinematic keypoints corresponding to a joint of the first subject, the first image capture device associated with a first view of the first subject, a multi-view associator to verify the first subject using the first image and a second image captured by a second image capture device, the second image capture device associated with a second view of the first subject, the second view different than the first view, and a keypoint generator to generate three-dimensional keypoints for the first subject using the first set of two-dimensional kinematic keypoints.

Abstract: The present invention provides devices, systems and methods for providing a user with haptic feedback, thus connecting the user with a virtual or remote environment. The device includes a plurality of fluid compartments that can be expanded or collapsed to provide tactile sensations to a user. The device design can provide continuous, dynamic and variable feedback that allows a user to distinguish between different virtual objects. The invention provides enhanced spatial and temporal resolution, hence providing more realistic sensory feedback and allowing for immersion into virtual or augmented reality environments.
