3. Problems 1.People don’t know how close they are for products they want. 2.Receiving too many irrelevant advertising. 3.Filtering and remembering the information we want.

4. Problems’ consequences  Stores: incomes are potentially decreasing.  Buyers: time for buying desired products increases.  Conclusion: “Traditional” advertising (newspapers, TV, Internet etc.) does not solve these problems.

5. Solution

6. Direct Advertising  Direct advertising maximizes the emotional side of the buying procedure.  When people notice something they need, there's more chance they’ll buy it.  Next – we’ll show an example of direct advertising in Cellular phone.

7. Cellular phones  SMS information system,known as Tip-Com in Cellcom.  User with mobile phone can join the service.  By that he agrees to receive SMS messages from advertisers.

8. Cellular Disadvantages  User has no control over the timing of messages - can be very annoying.  No filtering options on the incoming messages.  No touch screens.  Small screen, about 3 times smaller than PDA’s screen: –Hard to read –smaller advertisement field

9. CSP Solution

10. CSP - Contents  Brief Description  Requirements –Client –Service Provider  Implementation  User Interface

11. Brief Description  CSP – Commercials Service for Palm.  Offers immediate messaging sending: –Stores send commercials into palms of buyers that:  interested in their products  make themselves discoverable  Stores pay for subscribing into our service, while buyers subscribe for the service for free.  Communication between user’s palms and store’s PC is done via Bluetooth.

12. Brief Description (cont.)  Our service includes two steps: Configuration and Notification 1.Configuration : Preparing a TOBuy list in the palm of the products. 2.Notification: Stores notify users (both registered in CSP) in their range.  Notification will be sent only if the user chooses to make himself “discoverable”.

13. Requirements  Client (User)  Client (Store)  Service Provider

14. Client (User)  Palm device  TOBuy list:  TOBuy list:  Bluetooth chip  The same application as in the stores’ PC.  Registration to the CSP service.

15. Client (Store)  PC: acts as a proxy between the palms and the server.  BT chip: installed on a PC, acts as a sensor for other BT devices in its area.  Internet connection between the PC and the server.

16. Service Provider  Database – contains: –preferences of users ( configured during the configuration step). –Stores’ products, prices, ads.  Server – queries the DB for matches between users’ preferences and available products in each of the stores in the configured radius.  Internet connection between the server and the PCs.

17. Implementation  PC’s Bluetooth chip  Palm’s Bluetooth chip  Battery Life  Design  Proof of Concept

18. Bluetooth token (PC) Bluetooth USB dongle for PC

19. Bluetooth token (PC) - description  Connects the PC using USB port.  Contains a tiny radio transceiver that can communicate with BT devices in its range.  Data Transfer Rate: 5MBps  Receives signals even between walls.

20. Bluetooth chip (Palm) Bluetooth chip for Palm Enables communication with devices located within 10 meter radius

21. Battery Life (Bluetooth spec.) Battery Life (Bluetooth spec.)  Palm m505 has capacity of 540mAh at 3.7V about 20 hours of full processing.  Palm itself consumes 23mA (65mA with backlight).  Palms in standby mode (discoverable) will consume up to 0.3mA.On data transfer up to 30mA.(according to the Bluetooth spec).  Palm battery life time will reduce in only 10% when transferring data, and about 1.5% in standby mode.  Maximum “discoverable” time of a battery with a maximum 30 mA is 18 hours.

22. Design  BT sensor inside the store senses all the devices in its area that contain BT chip.  The sensor is in charge of: –Communicating with the PC. –Sensing all the devices with BT chip, not just discoverable palms.  Each BT chip has a Unique ID (UID).  The PC sends the UID to the server.  The server checks if the DB contains such UID.  If so, the ToBuy list is transferred from Palm to PC via silent FTP.

23. Design (cont.)  The PC sends the ToBuy list to the DB  The server sends back a list of products to the PC  This list contains all the stores that: 1.Offer products the user has chosen in its TOBuy list. 2.Their distance from the user is no less than the distance the user configured earlier. 3.Product's prices.  The PC sends ads to the palm.

24. Problems with current technology  A store is able to receive signals from Palms in radius of no more than 10 meters: –Palm Bluetooth token’s transmission radius is only 10 meters. –PC Bluetooth token’s transmission radius is only 10 -20 meters.  Our design minimizes this problem: –All stores are connected to one main server. –The server sends the store that first recognized the user details about all the stores that offer the items in the user’s TODO list. –This list contains stores that can be far more than 20 meters distance from the user (depends on the user’s configuration of maximal distance from stores in the list).

25. Proof of Concept  Establish BT connection between PC and Palm in both directions.  Shopping search engine, technology and implementation already exists. –i.e.: http://froogle.google.com http://froogle.google.com  ToDo list application exists on Palms. Adding the ‘budget’ and ‘radius’ fields is easy.  All we need to do is integrating existing technologies into on CSP product.
