Abstract: An input panel for an interactive input system comprises an optical waveguide; a first radiation source directing radiation into said optical waveguide, said radiation undergoing total internal reflection within said optical waveguide; a diffusion layer adjacent to and on one side of the optical waveguide, totally internally reflected light being frustrated and escaping the optical waveguide in response to pointer contacts on the diffusion layer; a second radiation source directing radiation towards another side of the optical waveguide that is opposite the one side; and at least one imaging device having a field of view looking at the optical waveguide and capturing image frames, wherein said first and second radiation sources are turned on and off in succession and wherein said first radiation source is turned off when said second radiation source is on and wherein said first radiation source is turned on when said second radiation source is off.

Abstract: Results of a Location Based Search can be saved for later use. The results can be saved as a contact in a contacts application. The device may automatically populate various fields of a contact based on a request by a user to save the search result as a contact. Once saved as a contact, the location based search result contact may be used to place a phone call, send an e-mail, access a website, review a menu, or take some other action.
