Abstract: The invention pertains to a terminal for exchanging messages by placing tokens near it. The terminal comprises communication means to exchange information with a database, detection means for identifying local tokens placed near the terminal, display means for displaying remote tokens, and proximity logic configured to assert a proximity relationship between tokens or between a token and a reference point. The terminal exchanges information about the topology of its tokens and that of tokens present at other terminals via the database. The terminal displays tokens present near remote copies of the local tokens, based on information obtained from the database.

Abstract: The mobile device includes a visual input device, for capturing external visual information having real visual background information, and a processing device. The processing device is for associating a selected application with the external visual information, and for executing the selected application based on the external visual information and on user-related input information. The processing device for generating a visual output signal related to at least one virtual visual object in response to the application is further configured to provide the visual output signal to a projector device included within the mobile device such that the projector device will be configured to project said visual output signal related to the at least one virtual visual object onto the visual background, thereby modifying said external visual information.

Abstract: Method for creating a camouflage cover for an electronic device having one or more components, said electronic device being intended to be arranged at a location, said method comprising: capturing an image including said location; obtaining size data of at least an area shown in the image, said area including said location; providing said electronic device with a display adapted for substantially hiding said one or more components of said electronic device when arranged at said location; said display having a display size; determining a digital camouflage pattern based on the captured image, the size data and the display size; displaying said digital camouflage pattern on said display so that a camouflage cover is obtained for the electronic device.
