  3. 3.  Wearable Technology is a portable computer that is included into the space of a user, this can be worn anywhere around the body and can be hands free use.  In this wearable computer differs from PDA’S (personal digital assistant),which are designed for hand held use.  They may also be integrated into everyday objects that are constantly worn on the body, like a wrist watch or a hands-free cell phone.  Particularly it is a device that is always with the user, the user is able to enter commands and execute a set of entered commands while the user is walking around or doing any other activity. INTRODUCTION
  4. 4.  Wearable Computers were first introduced by Quing dynasty in the 1500's with the pocket watch.  In 1600’s Robert Dudley developed abacus ring for help trader  In 1800’s watchmaker breguet developed a packet watch on bracelet chain for Nepal queens  In 1967, Hubert Upton developed a technology which allowed the person wearing the glasses to lip read, this was using the LED device.  Even in the 1980's and the 1990's wearable computers were being created. History of wearable computers
  5. 5. Wearable computing devices Steve Mann’s wearable computer and reality mediator inventions.
  6. 6.  To develop new interfaces that modify non- computer activities.  Without interfering with the user’s everyday tasks.  The design of wearable computers is still a topic of research & a variety of user interfaces are being proposed. AIM OF WEARABLE COMPUTERS:
  7. 7.  Consistency: The signal flows from human to computer and computer to human continuously to provide a constant user interface.  Enhancement :The assumption of the wearable computing is that the user will be doing something else along with computing. Thus, the computer should serve to increment the intellect or augment the senses.  Mediation: acts as a mediator as it aids its users by providing its umpteen applications in medical care  Privacy : Wearable computing can be used to create a new level of privacy  Convenient :It is verry convenience to the user.  Unrestrictive :Wearable devices enable a person to do multi tasking . Features of Wearable Computers
  8. 8.  Some wearable computers use “keyers” (key switches mounted to a grip, rather than to a board, as with a keyboard) and trackballs as input device.  Many try to use more intangible means of input like gesture, speech recognition or context awareness.  The output may be presented through displays, lights, sound or even haptic interfaces(touch screen).  Some mediated reality (ability to modified reality) systems can also be considered wearable computers.

  10. 10. >>Wearable Computer Implementation>>Input Device  speech recognizer:- Speech recognition is used to identify words in spoken language. Voice recognition is a biometric technology used to identify a particular individual's voice.  keyboard alternative including chording keyboards (few keys keyboards)and special purpose keyboards  mouse alternatives including trackballs, joysticks  tab alternatives including buttons, dial  eye trackers: eye tracking is the measurement of eye activity. Where do we look? What do we ignore? When do we blink?  head trackers :Head tracking is used in many games to measure the movement of your head in the real world  pen  gesturing  bar code reader  video capture devices, microphones, GPS locators
  11. 11. >>Wearable Computer Implementation>> Output Device head mounted displays (HMDs) flat panels, text to speech tactile output non speech auditory output paper and olfactory output (scent)
  13. 13. Application Wearable computing In Military field Wearable devices 1)HUD 2)Radio Modem 3)GPS 4)Computer 6)Flat panel
  14. 14.  The advantages of Wearable Computers are:- - Enhanced Communication - Multi-tasking -Consistent - Unrestrictive - Mobile - Work from anywhere - Convenience The disadvantages of Wearable Computers:- - 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 Advantages And Disadvantages
  15. 15. The use of mobile and wearable computers as actual “tools” on the construction site will enable interaction with smart infrastructure systems in the future. But to reach this goal, we face some challenges that have to be solved. Conclusion
