Abstract:
1. A method for creating an audible sound field for an interactive display system that includes an interactive display surface that is generally horizontal, around which one or more users may be disposed at different locations, comprising the steps of: physically coupling more than two audio sources to the interactive display system, at spaced-apart points around the interactive display surface, so as to produce audible sound directed outwardly relative to a periphery of the interactive display surface; determining a location of a user, who is currently interacting with the interactive display surface, relative to the interactive display surface, and wherein the location of the user is determined from a plurality of different possible location from which the user can interact with the interactive display surface; and based upon at least the determined position of the user relative to the interactive display surface, selectively energizing a first combination of at least one specific audio source of the more than two audio sources, so as to create an audible sound field that is logically associated with at least the determined location of the user relative to the interactive display surface, and wherein the at least one specific audio source is energized so as to generally center the audible sound field about the disposition of the user and wherein a different combination of one or more of the more than two audio sources will be selectively energized when the user is determined to be located at a different location of the plurality of different locations relative to the interactive display surface.
