What is Ubiquitous Computing?

  Ubiquitous computing (ubicomp) is an

advanced computing concept where computing is made to appear everywhere and anywhere.

The idea behind this sort of computing is to make the computing power disappear in the environment, but will always be there whenever needed or in other words it means availability and invisibility. 

Example of a Ubiquitous Environment: Lights, Air conditioning, TV's

automatically switch on or off when you enter or leave.

Sit on your chair and the TV sets your favourite channel which you usually watch ay this time of the day.

Route input from 'virtual' keyboard to nearest suitable display.

WHERE DID IT COME FROM

The underlying technologies to support ubiquitous computing include Internet, advanced middleware, operating system, mobile code, sensors, microprocessors, new I/O and user interfaces, networks, mobile protocols, location and positioning and new materials.

HARDWARE REQUIREMENTS Sensors: A sensor is a converter that measures a

physical quantity and converts it into a signal which can be read by an observer or by an instrument.

Actuators: An actuator is a type of motor for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, and converts that energy into motion.

HARDWARE REQUIREMENTS

PORTABLE WIRELESS RFID READER/WRITER: Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects.

HARDWARE REQUIREMENTS

1.Display Devices: Liquid Crystal technologies (LCD) Organic LED based Display

2.Storage technologies: Non-volatile Flash Memory Battery-backed RAM

DESIGNING Nanotechnology: The trend toward miniaturization of computer

components down to an atomic scale is known as nanotechnology. Nanotechnology involves building highly miniaturized computers from individual atoms or molecules acting as transistors, which are the heart of the computer chip. The number of transistors in a chip is indicative of its power. Therefore, nanotechnology’s extreme miniaturization of transistors allows for impressive levels of computing power to be put into tiny packages, which can then be unobtrusively tucked away.

DESIGNING Wireless: Wireless computing refers to the use of wireless

technology to connect computers to a network. Wireless computing is so attractive because it allows workers to escape the tether of a network cable and access network and communication services from anywhere within reach of a wireless network. Wireless computing has attracted enormous market interest, as witnessed by consumer demand for wireless home networks, which can be purchased for several hundred dollars. The second author has a three-computer wireless network in his home.

DESIGNING

Another approach is to implement the target system in a simulator and do the testing there. Although the focus of this technique should lie on the design of the protocols, a lot of time goes into the implementation instead of the design. Addressed tests are generally done under unrealistic conditions with a very small subset of features, a small number of nodes and unrealistic environment. The predictability gained from those isolated tests is basically zero

Applications

1. Smart Home for Elderly

An elderly person lives in an apartment with being handicapped in various ways.

His relatives wants to keep an eye on him 24/7.

Objectives

To develop a monitoring and sensing system.

To capture vital signs of elderly.

To gather data and make it accessible.

System Architecture

Database Server.

Cameras & Microphones.

Sensors.

a. Floor Pressure.

b. Infra-red.

c. Light.

d. Pulse oximeter & Blood pressure.

An overall layout of the elderly monitoring system

Database stores the information.Cameras and Microphones gathers video and audio information.FPS is used to track residents or detect furniture positionsInfra-red sensor to detect infra-red sources.Pulse oximeter & Blood pressure are medical wearable sensors.

Health Monitoring postoperative monitoring of patients;

monitoring of patients with chronic diseases;

social networking of relatives and peers for monitoring of elderly;

lifestyle and general well-being monitoring (e.g., to deal with obesity);

Health Monitoring

wellness and exercise monitoring; monitoring vitals and status of soldiers

and firefighters; emergency medical care and mass

casualty events; computer-assisted rehabilitation and

therapy; and development of new emergency

services with prolonged monitoring.

CONCLUSION The Ubiquitous computing due to its context

awareness and the natural interaction provides an intelligent environment in which user can easily avail desired services in an intelligent manner such as identification of user likings place time etc.

In the long term as pervasive computing is integrated into everyday objects, they become networked information control systems that are presently centralized in industry, transport, the service industry and the public sector can be decentralized.

Thus we can say that ubiquitous computing could be the next wave in the technology of computers
