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.
