3. Computer Computer Memory Memory Radio Radio Power Power What is RFID? • Radio Frequency IDentification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or Readers 1. Reader with Antenna 2. RFID Tag RF 3. Application (to Computer Host / server)

4. History of RFID Development RFID technology was used initially for military purposes It was used for commercial purposes, mainly for Electronic Item Surveillance (EIS) tracking and tracing. Its applications were expanded to admission control, toll charging, livestock management, and parts management. Research and development of the track and trace of products had been extremely active due to the actual demand of global logistics/distribution companies and new technologies and standards of track and trace which had been established. Medical and healthcare industries started to adopt and apply RFID technology and related applications, which is known as “ubiquitous health” World War II 1960s 1970s-1990s Around the end of the 1990s Recently

6. Tag and Reader “Depending on the products and environment, the right type of tag and Reader should be selected.”

7. Application of RFID in SCM David C. Twist, The impact of radio frequency identification on supply chain facilities, Journal of Facilities Management, vol.3, no.3. pp.226-239 “There are many kinds of products. The majority of inventory theft is done by employees.”

8. Application of RFID at Home • Healthcare mirror • - diagnose a skin status • Assist their memory • Monitor an activity and movement • Disease sensing

9. Bio-signal sensor module Applications in hospital • The ubiquitous technology replaces the current complex and inconvenient body signal detector. • This technology can detect patient’s condition and give a warning Hospital

10. To what field can we apply RFID next?

11. Aerobic capacity test • Aerobic capacity is one of the most important areas of any fitness program (Blair et al., 1992; Cureton, 1994; Cureton et al., 1995; Cureton & Warren, 1990) • PACER and 6-min walk (one mile walk or run) test are widely used field tests in assessing aerobic capacity. • AEROBIC CAPACITY 1) PACER (Progressive Aerobic Cardiovascular Endurance Run) – Set to music, a paced, 20-meter shuttle run increasing in intensity as time progresses 2) One-Mile Run – Students run (or walk if needed) one mile as fast as they can 3) Walk Test – Students walk one mile as fast as they can (for ages 13 or above since the test has only been validated for this age group)

12. Scoring Subjectivity Challenges • Wasted much time and labors • One tester/observer is needed for each student tested. • Human errors will likely be high in scoring recording • Misestimate aerobic capacity of examinees. • Attention demands on the testers are very high. <Individual score sheet> Fortunately, these limitations can be eliminated by employing Radio Frequency Identification (RFID) technology.

14. RFID based auto scoring system for PACER • It is possible to use passive tags • Reader can be connected with 2-4 • antennas • The antenna’s reading distance is 2-3m Reader Antenna Person attached passive tag

15. RFID based auto scoring system for Walk/Run test • It is possible to test using only one reader and one antenna • (at least one) • Many people can be tested at the same time. • In addition, even if they started at a different point (Under the RFID Reader) on the track, RFID system can track them. Reader Antenna Person attached tag 1 mile track

21. Run/walk test system in the “Park or Gym” • RFID can be applied in • Many automatic estimating a person's energy expenditure when he/she is doing exercise in a Gym or Park Sever and screen RFID Reader + = <Kiosk> Printer RFID Tag Printer

22. Tracking patients during their rehab exercises • RTLS system • Mobile unit or tag sends a radio message that is received by three or more location receivers • Using Active tag • Each receiver records the time of arrival

23. Track and Trace a ball in the court • Automatic recording system 35% 10% 45% 50% 45% 25%

24. Conclusion and Future Study • Conclusion • RFID can be applied in many different fields. • It can be used in kinesiology but with no previous application. • As an interdisciplinary study, the synergy resulting from combining engineering field and kinesiology field could take the related industry to a new level. • Future study • After Developing the system, we will apply to a variety of sites. • After collection of tested data, we will evaluate the results. • To access the result easily, we will connect this system to web site.
