• Filtering and remembering the information we
  want.

  these problems.

Direct Advertising

  of the buying procedure.
• When people notice something they need, there's
  more chance theyll buy it.
• Next well show an example of direct
  advertising in Cellular phone.

• 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.

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.)

• 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
• Offer products the user has chosen in its TOBuy
  list.
• Their distance from the user is no less than the
  distance the user configured earlier.
• 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 tokens transmission radius is
  only 10 meters.
• PC Bluetooth tokens 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 users TODO list.
• This list contains stores that can be far more
  than 20 meters distance from the user (depends on
  the users 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
• 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.
