Ubiquitous Computing
An Overview
Vishwajeet Vatharkar
www.vishwajeetv.com
Ubiquitous
[yoo-bik-wi-tuh s]
adjective
Existing or being everywhere, especially at the
same time; omnipresent.
Ubiquitous Computing
AKA
Pervasive Computing
or
Ambient Intelligence
or
Internet of Things
Where computing is made to appear everywhere and anywhere.
- https://en.wikipedia.org/wiki/Ubiquitous_computing
Core Properties /
Requirements of UbiCom
Applications
• Computer to Computer Interactions - Universal
content access and control
• Human to Human Interactions - Productivity apps
• Human - Physical, Computer - Physical Interactions
- Smart homes, environments etc.
Smart Devices and Services
• Smart Devices Characteristics - Mobility, Open
Service Discovery, Intermittent Resource Access.
• Smart Devices -
• Tans, Pads, boards,
• Dust, skin, clay.
• Distributed Systems ViewPoints
•
• Partitioning and distributing components
• Reducing system complexity by abstraction -
• Modularisation (high cohesion, loose coupling),
Interoperability, Transperancy, Virtualization
• Service Oriented Computing
• Service Provision Life Cycle -
• Service Discovery Interaction Patterns
• Service Invocation - Co-ordinated, on-demand, volatile
• Service Composition
Human Computer Interaction
(HCI)
• Researches the design and use of computer
technology, focusing particularly on the interfaces
between people (users) and computers.
Human Centered Design
Implicit HCI
• “An action, performed by the user that is not
primarily aimed to interact with a computerized
system but which such a system understands as
input.”
• Model of Human used as additional input
• Need to share implicit context between human and
system
• Implicit interaction naturally supports hidden device
design.
iHCI with Smart Devices
• Single vs Multi Modal visual interfaces
• Gesture interfaces
• Reflexive vs Active Displays
• Natural Language Interfaces
• Combining input and output interfaces.
• Tangible User Interfaces
iHCI with Wearables
• Using technology to extend a person's normal
conscious experience.
• Command and Non-command interfaces
• Non - command interfaces - motion segmentation,
object classification, tracking, interpretation.
• Brain Computer Interfaces
• Computer implants (cyborgs)
• Virutal, Augmented, Mediated Realities
• Telepresence and Telecontrol
