digital jwellery

2. INTRODUCTION
We feel bored to sitin frontof computers for a long
time.It would be comfortableif the smartdevices canbe
reduced to even more handy size.Mobile phones remind
us of importantdates,passwords,worksto be done on
time,etc.How willit be if our bracelet reminds us our
friend’sbirthday?.Let’s see how it couldbe done.

3. WHAT IS DIGITAL
JEWELLERY?
Digitaljewelry is thefashionjewelry withembedded
intelligence.Digitaljewelry can help you solve problems like
forgottenpasswords and security badges. "Digitaljewelry"is a
nascentcatchphrase for wearable ID devices thatcontain
personal informationlike passwords, identification,and account
information.They can also solve a common dilemma of today's
wiredworld - the forgottenpassword. "DigitalJewelry" looks to
be thenext sizzling fashiontrend of the technological wave.

4. Components of digital jewelry
Cellphoneswill bebrokenup into their basic
componentsand packaged as various pieces of
digitaljewelry. Each pieceof jewelry will contain a
fraction of the componentsfoundin aconventional
mobilephone.Together,the digital-jewelrycell
phoneshouldwork just like a conventionalcell
phone.

5. The various components that are inside a cellphone:
 Microphone.
 Receiver.
 Touch pad.
 Display.
 Circuit board.
 Antenna.
 Battery.
IBMhas developed a prototype of a cellphone that consists of several
pieces of digital jewelry that will work together wirelessly, possibly with
Blue tooth wireless technology, to perform the functions of the above
components.

6. The pieces of computerized-jewelry
phone and their functions:
Earrings-Speakers embedded into these earrings will be the phone's
receiver.
Necklace -Users will talkinto the necklace's embedded microphone.
Ring-Perhaps the most interesting piece of the phone, this "magic decoder
ring” is equipped with light-emitting diodes (LEDs)that flashto indicate an
incoming call. Itcan alsobe programmed to flash different colors to identify
a particular caller or indicate the importance of a call.
Bracelet-Equipped with avideo graphics array(VGA) display, this wrist
display could also be used as a calleridentifier that flashes the name and
phone number of the caller.

10. It's the voice-recognitionsoftwarethatwill be used to
make calls,a capabilitythat is alreadycommonplace in
many of today's cellphones. Simply say the name of the
person you want to calland the phonewill dialthat
person.

magic decoder ring

12. IBM's magic decoder rings willflashwhen you get a call.
The same ring that flashesfor phone callscouldalso
inform you thate-mail is pilingup in your inbox.This
flashingalertcould alsoindicatethe urgency of the e-
mail.the eyepiece above displaysimages anddata
received wirelesslyfrom the Communicator'sbelt
module.

13. Track point technology
The mouse-ring thatIBM is developing will use the company's TrackPoint
technology to wirelessly move the cursor on a computer-monitor display.
(TrackPoint is the little button embedded in the keyboard of some
laptops). IBM Researchers have transferred TrackPoint technology to a
ring, which looks something likea black-pearlring. On top of the ring is a
little black ball thatusers will swivel to move the cursor, in the same way
that the TrackPoint button on alaptop is used. This TrackPoint ring will
be very valuable when monitors shrink to the size of watch face.

14. Technical details
Digitaljewelry devices consist of a screen or display for
information,most likely consisting of 7-16-segment, or dot
matrixLEDs, LCDs, or other technologiessuch as
electroluminescentmaterial (EL) or others. It has external
switches and buttonson its side and a data-port for accessing
theprogrammable electronic circuit inside. Amicro controller
thatis a surface mounteddevice (SMD) on a printedcircuit
board (PCB) with resistors (R)and capacitors (C) are theinternal
'guts'of the jewelry.

15. Electromagnetic beads

16. The closest comparison to thismodel is thatof 'beads'
which are strungtogetherto makea custom necklace or
bracelet, with interchangeableelectromagneticcomponent
systems or devices. One bead may be a capacitor on the inside,
and a solar panel on the outside.
Another bead may have aninternalresistor whichfeed power
into a programmed microcontroller bead which drives an
externalscreen.

17. Java ring
The devices we use are protected by passwords. It
can be frustrating trying to keepwith all of the
passwords and keys needed to access any dooror
computer program. Dallas Semiconductor is
developing a new Java-based, computerized ring
that will automatically unlock doorsand log on to
computers.

19. The Java Ring is a stainless-steel ring, 16-millimeters
(0.6 inches) in diameter, which houses a 1-million-
transistor processor, called an iButton. The ring has 134
KB of RAM, 32 KB of ROM, a real-time clock and a Java
virtual machine, which is a piece of software that
recognizes the Java language and translates it for the
user's computer system.

20. Highlights of java ring
Runs Java better (plusportions enhance Java Card 2.0)
Careful attentionto physicalsecurity
Durabilityto stand up to everyday use
High memory capacity(up to 134Kbytes)
Retailconnectivity to250 millionexistingcomputers

23. Advantages
• Itprovidessecurity.
eg.javaringisusedtolockorunlockdoorsand
computers.weneednotremember anypasswords.
• Sincealldevicesareembedded,weneedn’tcarry
mobilesorcomputerswithus.
• Providesfastertransmission,theftlossprotection

24. Disadvantages
• Chargingcapabilities
• Cost.

25. Conclusion
“By the end of the decade, we couldbe wearing our
computers insteadof sittingin front of them”
Thebasic idea behind the digital jewelry concept is to have
the convenience of wireless, wearable computers while remaining
fashionably sound.
 It is hoped to be marketable soon, however, several bugs
remain. Charging capabilities and cost are just a sample of the
problems that lurk
