Abstract: An apparatus for capture-based telepresence in a virtual environment session, comprises 3D capture devices to continuously capture image data of a first user. A processing unit comprises: an image processor for continuously producing a first 3D representation of the first user based on the image data, the first 3D representation having at least punctually a user specific position in a virtual environment. A data transmitter transmits the first 3D representation for remote use in the virtual environment session. A data receiver continuously receives a second 3D representation of a second user, image data for the virtual environment, and at least punctually receiving user specific position of the second 3D representation relative to the virtual environment. A rendering engine outputs for display the 3D representation of the second user positioned relative to the first user as inserted in the virtual environment based on said user specific positions.

Abstract: An image display system for surrounding a horizontal field of view of a viewer with images. The image display system comprises a portion of a sphere having a concavity defining an inner surface. A projection device is adapted to project images from a center of a radius of curvature of the portion of a sphere so as to project images on the inner surface of the portion of a sphere. The image display system is adapted to partially receive viewers in the concavity such that at least a horizontal field of view of the viewers is surrounded by an image projected from the center on the inner surface of the portion of a sphere.

Abstract: A portable utility bag of the packsack type adapted to vary its volume in relation with the content thereof at any moment and which includes a pair of tying bands defining a handle portion, or shoulder strap portions, to selectively use the bag as a handbag, shoulder bag or backpack. This portable utility bag includes a pair of opposite walls defining a common peripheral edge having a straight common edge portion, a stiffening band along this edge portion, a slit in one of the opposite walls along the stiffening band, a closure selectively closing this slit, at least a pair of loops fixed along an opposite edge portion of the bag relative to the straight common edge portion, and tying bands protruding from the ends of said stiffening band engaging in these loops and tied together to form a handle portion, or shoulder strap, between the two loops, and shoulder strap portions intermediate the stiffening band and the loops respectively.
