Introduction(1)
Shop to Shop
Information on newly - released data in his favorite categories are downloaded automatically into his PDA , along with their availability information.
We refer to this paradigm as Location aware
computing.
Rover Services(1)
Enables a Basic set of data services in different media formats, including text, graphics, audio, and video.
Transactional services coordination of state
between the clients and rover servers.
ex) e-commerce interactions
Rover Architecture
Rover maintains a user profile for each end-user, that defines specific interests of the user and is used to customize the content served.
Rover-clients are the client devices through which users interact with Rover. Rover maintains a device profile for each device.
Action model
Ready-to-run: At least one action of the server operation is eligible to be executed but no action of the server operation is executing.
Running: One action of the server operation is executing ( in a multi-processor setup, several actions of the operation can be executing simultaneously ).
Blocked: The server operation is waiting for asynchronous I/O response and no actions are eligible to be executed.
Conclusions
We believe that Rover Technology will greatly enhance the user experience in a large number places, including visits to museums, amusement and theme parks, shopping malls, game fields, offices and business centers.
The system has been designed specifically to scale to large user populations. Therefore, we expect the benefits of this system to be higher in such large user population environments.
