- 2. CONTENT Introduction What is a wearable computer? History How does a Wearable Computer look? Application Advantages Disadvantages Conclusion
- 3. INTRODUCTION The vision behind the concept of a wearable computer is that a mobile computer should not just be a machine that we put into our pocket when we plan on doing some office work while on the road. Instead it will be an integral part of our every day outfit (hence wearable), always operational and equipped to assist us in dealing with a wide range of situations.
- 4. WHAT IS A WEARABLE COMPUTER? A wearable computer is a computing device small and light enough to be worn on one's body without causing discomfort. Unlike a laptop or a palmtop, wearable computer is constantly turned on and interacts with the real- world task.
- 5. HISTORY The concept of wearable computing was first brought forward by Steve Mann, who, with his invention of the ‘Wear Comp’ in 1979 created a pioneering effort in wearable computing. The 1980s brought forward the development of the consumer camcorder, miniature CRTs etc. brought forward the development of the eyeglass mounted multimedia computer.
- 6. HOW DOES A WEARABLE COMPUTER LOOK? A typical wearable computer consists of a battery or human powered computing unit and carried on a belt or in a jacket. A wearable computer will have a mother board worn inside a fashion garment, connecting all the components of the system.
- 7. COMPONENTS OF A WEARABLE COMPUTER Input devices: Speech recognition may appear as the most suited input device, but may not be preferred in all kinds of applications & environments, due to privacy and performance issues. Gesture Input devices are simple, compact, and optimized for wearable use. The output device of a wearable computer could be either a head-mounted display (HMD) unit with an earpiece or only the earpiece for some applications. The HMD works like an ordinary monitor, providing an image floating in the air in front of you. It uses LCD or TFT technology.
- 8. NETWORKS There are two different kinds of networks in reference to a wearable computer. One is to connect the device to the external world and the other is to interconnect the various components, the later one being new for wearable computers. The second issue of interconnecting the various parts of the WC may involve both wired and wireless connections. Peripherals like HMD and wrist/finger worn devices may use standard wireless connections like Bluetooth.
- 9. RATIONAL DETAILS SOFTWARE:The commonly used operating system on a wearable computer is WOS (wear comp OS). Red hat and GNU Linux can be run in close coordination as an operating system too. HARDWARE:Prices of wearable computers tend to be in "thousands of dollars" whether you buy old or new. An alternative approach is to assemble a low cost system.
- 10. DISPLAY A major part of the total cost of the wearable computer system lies in its display unit. Mainly two types of display are used. Common portable LCD display Head mounted display
- 11. COMMON PORTABLE LCD DISPLAY FEATURES:High resolution colour video image. Image that appears in the person's line of sight. Viewing angle comparable to viewing a 26" monitor from 2, meters (6.5 Feet) away. Ultra light-weight, no major disturbance in the eyesight.
- 12. KEY BOARD At the higher end, you can get a "twiddler" from Hand key, or keyboard from info grip. You can connect micro switches that enable you to plug directly into the keyboard port. HARD DRIVE: Many hard drives commonly used in laptop computers can withstand operational shock, it is common to go jogging while editing, and sometimes shoot momentary video while on horseback or riding a mountain bike down the centre of a line bumping over every railway tie, and capturing the experience on a hard drive.
- 13. BATTERIES OF WEARCOMP Low cost batteries:Early versions of wear comp used lead acid batteries. Lead acid batteries are typically available surplus. High performance batteries :Li-Ion camcorder batteries are commercially available. A minimum of two batteries is required for constant running 12 Volt batteries.
- 14. APPLICATIONS Augmented Reality Aiding the visually disabled Brain Gate Interface Data processing Patient Monitoring Digital imaging Remote guidance
- 15. ADVANTAGES Portability. Hands-free use. Comfortable. Always on for the task it is designed. Quick to access. Fashionable. Functions of clothing will be very personal. The reuse of clothes will be important (prolonged life cycle).
- 16. DISADVANTAGE 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.
- 17. CONCLUSION Wearable Computer has come a long way from the days of the Wear Comp. Extensive research and development work at various centers have ensured that these wonderful devices will change our lives dramatically in the near future. Several commercial vendors have started manufacturing and marketing these devices.
