2. What We Will be Covering
Purpose

Hardware

Interface
Risks and Challenges

3. Purpose
“How many people here actually know where they’re going?”

4. Purpose
“Are you making the most of your time at the career fair?”

5. Purpose
To develop a pervasive system to help students managing their time better while at the job fair by picking out the best booth to go to based on
Line length/Congestion
Employer/Student requirements
Student job preferences/filters

6. Proposed Solution
Create a system where students can “check in” at booths to inform system that he/she is waiting in that booth’s respective queue
Inform students in which order they should visit booths if they want to save time

7. How do we go about this?
We design a system where each employer uses their laptop which is connected to our server through the internet. Each booth will receive a card reader for which students will swipe and “check-in”.
Students query the server through either a terminal or by phone message to determine where they should go next.
Other features that may be implemented for check in include pulling information about the student onto the employer's laptop such as their resume etc.

8. Original Idea –Terminal System
This is the coliseum, you will scan your card to get your tag, use the that tag at the employer booths to indicate you are checked in to those terminals. To access data you scan cards/tags at terminals which print out a list of where to go next.

9. The Problems/ Benefits of Terminal System
Updating is not real-time, each person has to physically go back to a terminal to update his list
Using paper
May get crowded
Available to everyone in the coliseum
Easier to implement

10. Second Idea
Update through text messaging instead of terminals

11. The Problems/ Benefits
Disruptive (how to make sure everyone’s phone isn’t making noise)
Cost on the receiver side
Each person would have to give their cell information
Both active/passive systems possible
Pervasive as almost everyone has a cell phone
More dynamic and real-time

12. Tentative Solution A mix of terminals and text messaging service.
In this way we lower congestion at the terminals while allowing paperless real-time notification

13. The “Check-In” Quandary
What will we use to identify students
ISU Card
RFID Card/Tag

14. The Problems/Benefits of ISU Card
Security issues
ISU Card services is “doubtful” whether we can use the cards or not
More physical effort to swipe and re-swipe if errors
Employers need to use our software (more security risk)
Pervasive as students using our system has an ISU Card
Cheaper to implement than RFID
Card already needed to get information at Career Fair

15. Biggest Problem of All Proprietary System run by Simplicity
Blocked by ISU Card services based on legal / privacy issues

16. The Problems/Benefits of RFID Card
Everyone needs a one, not as pervasive as ISU Card
Expensive to buy readers for each booth
Only contains information we need (less security risk)
Easier to check in
Possibility to detect multiple RFIDs in certain range
ISU Lab available for use

17. Software Client/Server system for check-in/out and text messaging
Best fit algorithm for deciding employer visit order
Employer’s interface for use on their laptops
On-board program
Web-interface
Terminal printing
*Note not all of these will necessarily be implemented in the system

18. Interface
Interfacing between the hardware and software components will need use of a certain protocol
Possible options include TCP/IP, SMS
Protocols come at a later stage of the design process once the basic hardware and software components are figure out.
Employer – Card Reader interface

19. Plan Decide components we should/can use Research topics
Topics will depend on which implementation scheme we can go with
Design the system
Verify system meets clients demands
Assess financial feasibility
Get Expert Feedback
Create prototype system

20. Risks and Challenges Overcoming cost Implementing the system
Coordination
Team member leaves
Too much work
Time management
