WEARABlE COMPUTER
INTRODUCTION
• A “Wearable Computer” is a computer that could be worn on the body. Wearable computers could be anything from a small wrist mounted system to a bulky head mounted display as shown below:
• Wearable computers are especially useful for applications that require computational support while the user's hands, voice, eyes, arms or attention are actively engaged with the physical environment.
AIM OF WEARABLE COMPUTING
To develop new interfaces that mediate (augment, deliberately diminish, or otherwise modify) non-computer activities
Without interfering with the user's everyday tasks
The design of wearable computers is still a topic of research, and a variety of user
interfaces are being proposed.
HISTORY
1991: Started the ”Wearable ComputingProject” at MIT.
1995: World’s first covert wearable computer – cameraand display concealedin ordinary eyeglasses.
1997: PhD from MIT inthis field he himself hadinvented.
Today, 2010: Works at
University of Toronto (OffSpring).Steve Mann
EVOLUTION
IT ALL STARTED FROM 1980
PRESENT SCENARIO
After its invention, Wearable Computer have gone through 18 generations of development, with research going on at prestigious institutions like MIT, Georgia Tech and Carnegie Mellon University.
SIXTH SENSE
• Pranav Mistry is the genius behind Sixth Sense
• is a PhD student in the Fluid Interfaces Group at MIT's Media Lab. Before his studies at MIT, he worked with Microsoft as a UX researcher. Mistry is passionate about integrating the digital informational experience with our real-world interactions.

TECHNOLOGY AND GADGETS
What do you need for WEARABLE COMPUTER?
OPERATIONAL DETAILS
Software: The commonly used Operating System on a wearable computer is the WOS (Wear Comp OS). Redhat and GNU Linux can be run in close coordination as an Operating System too. Hardware: Display Keyboard Hard drive
HARDWARE
• Web cam, a 3M pico projector and a mirror, all connected wirelessly to a Bluetooth smart phone in his pocket. Which only comes out to be $350!!!
CAPABILITIES
• You hold up your left hand, fingers pointing to the right. The system recognizes that you want to make a call, and projects a dialing pad onto your fingers. You tap the virtual keypad with your right hand to dial the call.
CAPABILITIES- WEAR UR WORLD (WUW) WUW VIDEO DEMO
HOW WEARABLE COMPUTER WORKS
Some wearable computers use “keyers” (keyswitches mounted to a grip, rather than to a board, as with a keyboard) and trackballs as input device.
Many try to use more intuitive means of input like gesture, speech recognition or context awareness.
The output may be presented through displays, lights, sound.
There are three operational modes of interaction between human and computer
Constancy
Augmentation
Mediation
Interaction Between The User And The Computer
Constancy
The computer runs continuously, and is always ready to interact with the user.
Unlike a hand-held device, laptop computer, or PDA, it does not need to be opened up and turned on prior to use.
The signal flow from human to computer and computer to human, runs continuously to provide a constant user-interface.
Constancy

Augmentation
Wearable computing is based on the notion that computing is not the primary task.
The assumption of wearable computing is that the user will be doing something else at the same time as doing the computing.
Thus the computer should serve to augment the intellect, or augment the senses.
Mediation
Unlike hand held devices, laptop computers, and PDAs, the wearable computer can encapsulate us.
It does not necessarily need to completely enclose us, but the concept allows for a greater degree of encapsulation than traditional portable computers.
Thanks to encapsulation, it can function as an information filter, and allow us to block out material we might not wish to experience,
Commercialization of W.C.
Led by companies such as Xybernault, HandyKey, and ViA. Forced alliances with IBM and Sony in order to make wearable computing widely available.
In 2001 IBM developed and publicly displayed two prototypes for a wristwatch computer running Linux, but the product never came to market.
FEATURES
Consistency :There is always a constant interaction between the computer and the user and hence there is no need to turn the device on or off.
Multi-Tasking : Wearable computer provides computational support even when
the user’s hands, voice, eyes, or attention is actively engaged with the physical environment.
Mobility : Wearable computers must go where the wearer goes. They are
always on and their wearer can access them anytime.
General requirements
• Short-ranged• Simple in design• Low power consumption• Self-configuration• Restricted to the user• Security
Security requirements
• Privacy• Data Confidentiality• Data integrity• Access Control• Availability• Source Authentication
Wearable Computer Networking:-
APPLICATION
Augmented Memory Face Recognition Finger Tracking Visual filter Navigation Wearable computer in a Wrist Watch Wearable computer in Shoe
AUGMENTED MEMORY
Elderly or people with poor memory.– Remember name and face of people.
Image processing can recognize a face and map it to the person’s name and affiliation.
VISUAL FILTER
User wears non-transparent glasses
with integrated displays, experiences
the world through a camera. Computer processed video stream.
– Enhance contrast.
– Adjust colors.
– Night vision.
– Enlarged view.
WATCH WORKING ON LINUX
Wrist watch running Linux and XFree86.
Clock and video conferencing application.
OTHER APPLICATIONS
Military
– Soldiers monitoring,health, equipment, etc.– Maps and terrain.
Workers trining and support Architect Researchers
The glove controlled interface that the actor tom cruise manipulates in the film. Using a special pair of gloves, cruise can control a large screen in front of him, moving digital objects.
WEARABLE GAMING
BodyPad - group of wearable sensors - turn a person's arms and legs into a joystick for
PlayStation or Xbox fighting games.
ADVANTAGES
Portability. Hands-free use. Comfortable. Always on for the task it is designed. Quick to access. Fashionable.
LIMITATIONS
Equipment can be heavy. Expensive. Some Wearable Computers can consist of
a lot of wiring. Can cause irritation in heat. Side-Effects such as Headaches. It may become easier to get data on an
individual if the item is lost / stolen.
Conclusion
Whatever area wearable computer technology is applied to you can see that it will improve the quality of life and make day-to-day life less complicated.
