Device Coordination Use Case

Case 1.

• A user finds her favorite shoes at a shoe store in a mall. She obtains information by reading the RFID tag attached to the shoes with her personal device. Basic information (e.g., price, some product information, and recommendations) can be stored in the device. In this way, the user can acquire information on all her favorite shoes throughout the mall.
• The user meets her friends and goes to a cafe. They each transfer acquired information from their personal devices to a large-screen display device on the table via the cafe’s network. They can then compare information regarding their favorite shoes. Related content is searched for in the mall databases and on the Internet, and then the information acquired from the various sources is compared.

Case 2.

• After a meeting in a company, a PDA updates the task information assigned to a user into a task management program in a notebook.
• The task management searches data related to the new task.
• When the task management needs hard copy documents, it transfers the data to a printer and the printer prints documents.

Case 3.

• The task management perceives that the user will have a business trip next week.
• The task management reserves the hotel and the flight in accordance with user’s preference and pays the fee for the accommodation and a flight.

Case 4.

• A user wants to locate his/her child in the theme park. The user’s PDA reports the information about the child to a center for missing children.
• Fortunately, the child wears a watch with RFID. The center can allow the user to access sensory data with his/her PDA that are collected from sensors scattered around the park.
• The user’s PDA identifies the location of his/her child.
