Abstract: A virtual reality wearable system. The system includes a sensor, an actuator, a sleeve-type first wearable part fittable over a user's bodily part, the at least one second wearable part being wearable over the first wearable part. The first wearable part and the second wearable part are releasably connectable to each other. The at least one second wearable part supports the sensor and the actuator. A cable or cables connect the sensor and the actuator with a portion of the second wearable part distant from the sensor and the actuator. The at least one second wearable part comprises a first portion and a second portion that are separate from each other. The first portion is placeable on a first bodily part of a user, and said first portion supports the sensor and the actuator, and the second portion is placeable on a second bodily part of the user distant from the first bodily part.

Abstract: It is provided a method for conveying data on a flying object in a scene. The method including capturing video frames of the scene by video cameras to get video frames which include image of the object, identifying the object in captured video frames to get associated object parameters, calculating motion variables, solving motion equations for anticipated object trajectory taking into account certain effects, and conveying data to displaying devices. The certain effects are an effect of object collision with a ground surface, air friction, wind effect, and interaction of a spinning object with air. The method may be applied to a ball in a sporting playing field. The cameras may have variable operating parameters desirable for the calculating the motion variables, which may be determined by camera calibration using captured artifacts of the scene. Shadow of the object may be captured as well and be used to provide data absent due to occluding a of the object from a video camera.

Abstract: It is provided a method for converting video streams capturing a scene to video streams fitting a viewpoint configuration. The video streams are provided by video cameras, and the method includes receiving parameters associated with the viewpoint configuration, and converting video streams of the scene as captured by the video cameras to video streams fitting the viewpoint configuration. The viewpoint configuration may be a dynamic viewpoint configuration determined by a joystick module. The converting may be done using a three dimensional method, and includes separating objects of the scene from other portions of the scene. The method may includes integrating the scene into the video stream of a certain scene associated with the viewpoint configuration.

Abstract: A method for realistically implanting a non-floating. Computer Graphic Image object into a real camera image sequence filmed scene, and for obtaining roaming capabilities therein, including modeling a picture into which a Computer Graphic Image object is to be implanted by creating therefor imaginary borders, providing a three-dimensional vector representing the movement of the camera between each frame, and expanding said vector to a plane by calculating the movement of the camera while marinating its original angles; and therewith by respectively using an imaginary camera to render a 3D object on a screen of a computer and by respectively coordinating the filming camera's angle with the imaginary camera for implanting the Computer Graphic Image object in the image sequence filmed scene; wherein the method is characterized by implementing angular noise from the filming camera's angle to the object rendered by the imaginary camera.
