Question

Information Technology (IT) is an application of computers and telecommunications which stores, retrieves, transmits and manipulates data. It also encompasses other information technologies of a ubiquitous nature.

Describe using appropriate examples the ubiquitous nature of IT in the following cases. Clearly explain the input-output mechanism.

1. Wearable Computer

2. In the New Metro Express Project

Answer 1

With advancement in Information technology, the market for wearable computers have tremendously increased. From fitness tracker to heart rate monitoring, thermometers, etc are some of the latest wearable computers in the market.

Wearable computers will be either attached to the user's clothing or he/she can wear it as a wristband. These computers can be integrated with the smart phones/laptops, etc. It enhance's and boosts our day to day experiences and quality of life. The features of wearable computer which brings its immense popularity is 'always on capability' and 'continual accessibility'.

Keyers and trackballs act as input devices for wearable computers. These have sensors which tend to detect, monitor and track various things. Along with input through devices, these gadgets gather data from gesture, recognition or context awareness. The output can be displayed in form of light, sound or haptic interfaces.

Considering the example of google glass - it comes as a eyewear with a touchpad located on its side, which allows the user to swipe though the interfaces displayed on its screen. The interaction to the glasses is through the user's voice. The input to this device will be touch, speech, head movements, etc. and the output will be always available on the peripheral display.

In a new Metro express project, Information technology helps users with the ticketing system. Applications can be designed to manage the complete metro express projects to keep a record of train, train status, stations, passengers, ticket, etc.
Technologies such as GPS enabled in each train can help users track the live position of the metro trains with help of google maps - which again is an information technology application helping users to navigate geographically.
Automatic Vending machines configured to generate tickets automatically for users.
The Ticketing system can be used to generate QR code for tickets which can be scanned and the long queues can be avoided.
