BEGINNINGS OF UBIQUITOUS COMPUTING

While working atXEROX Palo Alto Research Center (PARC) as Chief Technologist, Weiser envisioned the third era of computing in 1985.

Weiser produced three types of wirelesscomputing devices

Pervasive computing technologiesPervasive computing involves three converging areas of

ICT computing (‘devices’) - PCS devices are likely to

assume many different forms and sizes, from handheld units (similar to mobile phones)to near-invisible devices set into ‘everyday’ objects (like furniture and clothing).

Communications (‘connectivity’)- This can be achieved via both wired (such as Broadband (ADSL) or Ethernet) and wireless networking technologies (such as WiFi or Bluetooth)

‘user interfaces’- new user interfaces are being developed that will be capable of sensing and supplying more information about users, and the broader environment, to the computer for processing

Applications of UbicompApplications of Ubicomp

Health care home care transport environmental monitoring


1. Health care

Pervasive computing offers opportunities for future healthcare provision both for treating and managing disease, and for patient administration

remote sensors and monitoring technology might allow the continuous capture and analysis of patients’ physiological data

Medical staff could beimmediately alerted to any detected irregularities


2. Environmental monitoring

Pervasive computing provides improved methods to monitor the environment

It will allow for continuous realtime data collection and analysis via remote, wireless devices

this poses significant challenges for PCS developers. Devices may be required to withstand harsh environmental conditions (such as heat, cold and humidity


3. 3. Intelligent transport systems

Such systems seek to bring together information and telecommunications technologies in a collaborative scheme to improve the safety, efficiency and productivity of transport networks

Electronic devices could be directly integrated into the transport infrastructure, and into vehicles themselves, with the aim of better monitoring and managing the movement of vehicles within road, rail, air and sea transport systems.


ChallengesChallenges

The “Accidentally” Smart Environment Impromptu Interoperability No Systems Administrator Social Implications of Aware

Technologies Reliability Inference in the Presence of Ambiguity


1. 1. The “Accidentally” Smart Environment

If you walk into an environment anywhere in the world, you would probably not find an infrastructure suitable for ubiquitous computing

Instead, you would find an infrastructure suited towards established and well-grounded technologies

the environments of users must be “upgraded,” to support this new technology


2. 2. Impromptu Interoperability

Ubiquitous computing must not just have interoperable devices, they must have impromptu interoperability – the ability to interconnect and communicate with little or no advance planning.

This presents a problem because every device must be written to understand the software of every other device


3. 3. Social Implications of Aware Technologies

Pervasive computing systems may have implications for privacy, security and safety, as a result of their ability to: gather sensitive data, for example on users' everyday interactions, movements, preferences and attitudes, without user intervention or consent

The advent of pervasive computing may mean that data can be collected without a person’s knowledge or consent. Some argue that this could violate existing data protection law


4. 4. Reliability

Since ubiquitous computing devices will be everywhere, it makes sense for them to be reliable.

Owners and developers will not want to be constantly bombarded by failing devices or insecure software.
