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.

Wearable computing facilitates a new form of human-computer interaction comprising a small body worn computer(eg user programmable device)that is always on and always ready and accessible.In this regard,the new computational framework differs from that of hand held devices ,laptop computers and personal digital assistants(PDAs).

Wearable computing is a kind of “extension” of your body that allows you to perform “extraordinary” tasks. Something that you never could do using only your body.It is like becoming a “super-hero”: you can be in more than one place at the same time…Wearable computing researchers have discovered ubiquity!

The extension idea is useful for understanding the real implications of wearables in work contexts. A wearable computer is an extension but a superlative one. For example, it can be an otherwise ordinary piece of clothing but with integrated communication functions.Safety at work could be improved by allowing us to communicate our position immediately in case of problems or danger. Productivity could be improved by allowing the factory worker easy access to distant information sources almost immediately, thereby allowing him to solve problems on the spot and save time.

These are just two examples of the ways wearable computing can make the workplace safer, more comfortable, and more productive. Many more workplace applications are waiting to be developed. There are many possibilities in different industry sectors.

What do you need for W.C.?

  • Head-mounted display.
  • Camera recording view.
  • Audio, e.g. speaker and mic.
  • Input device, e.g. keyboard.
  • The computer itself.
  • Network connection

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.

OPERATIONAL DETAILS

Software:  

The commonly used Operating System on a wearable   computer is the WOS (WearComp OS). Redhat and GNU  Linux can be run in close coordination as an Operating  System too.

Hardware: 

-Display

The display device of a wearable computer is a head-mounted display (HMD) unit with an earpiece.Though there could be several other display devices intended for specific applications, HMD systems are of interest in the conversation of wearable computers.

-Keyboard

A combination keyboard and mouse fits in the palm of your hand. The Twiddler2 is an enabling technology of wearable  computing.

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 Portability.

¨ Wearable computers can consist of a lot of writing

¨ Can cause irritation in heart

¨ Side effects such as headaches.

CONCLUSION

¨ 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.
