  1. Agenda • Introduction • Overview of Technology • HAN as a New Computing Realm • HAN& Technology • RedTacton • How It works • Features • Application • Comparison of Network(PAN) Technologies • Conclusion • Question

  2. Human Area Network ?

  3. Introduction Human Area network An emerging field of communications technology with the potential to offer significant advantages to Pervasive computing. (military operations, smart home etc).

  4. Overview of Technology (1/2) Is the idea of “Pervasive computing” really old? -1988 Ubiquitous computing -“era that replaces PCs with invincible computers embedded into everyday objects.” Mark Weiser, 1952-1999 Father and founder of ubiquitous computing.

  5. Overview of Technology (2/2) Pervasive Computing Network Technologies: WPAN • Wi-Fi - [ IEEE 802.11 ]. • Bluetooth - [ IEEE 802.15.1 ]. • ZigBee - [ IEEE 802.15.4 ]. • and other RF technologies.

  6. Human Area Networks (HAN), exists within the Personal Area Network (PAN) bubble. The most frequent impacts to an individual are realized in those regions proximate to him. Human Area Networks as a New, “Adaptive” Computing Realm (1/3) WAN and MAN :: fundamental components enabling global interconnectivity.

  7. Human Area Networks as a New, “Adaptive” Computing Realm (2/3)

  8. Human Area Networks as a New, “Adaptive” Computing Realm (3/3)

  9. Human Area Network • Its a new technology which uses human body as transmission media. • It gives us safe and high speed network transmission. • Uses weak electric fields on the surface of the body as a transmission medium.

  10. Enabling Technology RedTacton

  11. RedTacton(1/2) • It leverages the conductive properties of the human body to transfer data among electronic devices. • Conceived and patented in the mid-1990s by Neil Gershenfeld and Thomas G. Zimmerman at the MIT Media Lab.

  12. RedTacton(2/2) • It is a new HAN technology that uses the surface of the human body as a safe, high speed network transmission path. • Uses the minute electric field emitted on the surface of the human body. • Technically, it is completely distinct from wireless and infrared.

  13. How it Works (1/3)

  14. How it Works (2/3)

  15. How it Works (3/3) The RedTacton transmitter induces a weak electric field on the surface of the body. The electric field sensor (transistor or photonic electric field sensor) detects electric field that reaches the RedTactonreceiver. Signals are processed in the receiver circuit and the data is downloaded. 1 2 3

  16. Block Diagram of Transceiver

  17. Features of RedTacton Max. speed of 10Mbps (Duplex)

  18. RedTactonPrototypes PC Card Transceiver • Transmission rate: 10Mbp • Protocol: TCP/IP • Transmission method: Half-duplex • Terminal interface: PCMCI • Embedded Receiver • Transmission rate: 10Mbp • Protocol: TCP/IP • Transmission method: Half-duplex • External device interface: 10BASE-T Web page: http://www.redtacton.com

  19. Application of HAN (1/2) • One-to-one services : Marketing Application (Context awareness) • Touch advertising & receive detailed information • Inside a shop, shoppers can view related information on their mobile terminals immediately after touching a product. • Intuitive Operations : private data exchange • And since data can pass from one body to another, you could also exchange electronic business cards by shaking hands

  20. Application of HAN (2/2) • Personalization: • Security application

  21. Comparing with other Network Technologies Wideband Code Division Multiple Access Personal Digital Cellular Personal Handy-phone System Ultra Wideband

  22. Comparison with other network

  23. Conclusion • Unlike wireless, interception is difficult and security can be considered to be high with RedTacton • When we compare this with other technology present today it can give a better performance over others • It conforms to the “Radio Frequency-Exposure protection Standard (RCR STD-38)” issued by the Association of Radio Industries and Business (ARIB) • Still undergoing development: doesn’t work reliably yet. (common with emergence of new technology) • Supports the vision & future of pervasive computing
