Abstract: Systems, methods, and apparatus are provided for distributed augmentation. In one implementation, a system is provided. The system includes one or more presentation applications, each presentation application operable to provide a presentation output and a plurality of augmentation and presentation control (iAPC) modules operable to provide user augmentations of the presentation output. The system also includes one or more distributed augmentation and presentation management (DAPm) modules operable to separately manage augmentations from the presentation output and to provide an augmented presentation output and one or more display devices for presenting the augmented presentation output.

Abstract: The invention relates to a method for the wireless access of computer-based services in an attributable manner, using a mobile hand-held device, by a service user who is temporarily in the vicinity of a local service computer, on which service software comprising an input for services and preferably an output for services is run. Said service software can be distributed among additional service computers. To access said services, the services user uses a personal, mobile hand-held device, which comprises a standard input/output and preferably a simulation system for the interactive entry of service data. The mobile handheld device for accessing a service interacts with the service software is a distributed service access and a wireless connection. The mobile hand-held device and the service computer transmit data, whose attributability is to be guaranteed, by means of digital signatures, according to an agreed protocol.
