Abstract
A first device (such as a cell phone) is equipped with a micro-projector, and used to present imagery on a display surface. A second device (such as a second cell phone) is equipped with a digital camera, and used to capture some of the projected imagery. The captured imagery allows a user of the second device to access digital content of interest from a user of the first device, or from elsewhere. The content may be visual, or of other form (content examples include audio, games, maps, text documents, video, spreadsheets, etc.). In one particular arrangement, the projected imagery is encoded with digital watermark data. Through such arrangements, one user can readily share content, and also engage in collaborative activities—such as cooperative game play, with one or more other users. A great variety of other features and arrangements are also detailed.
