UBICOM: Ubiquitous Communications

Ubiquitous applications need to access relevant remote external information and tasks, anywhere and anytime.

Different applications require different combinations of network functions and services. e.g. data streaming, minimal jitter, specific media access control etc.

Ubiquitous communication plays a major role understanding the fundamentals…..

UBI COM: Tagging, Sensing & Controlling

To enable Smart (Physical) Environments, devices should:

Spread more into the physical environment, becoming part of more user activities in physical environment.

Be cheap to operate: autonomous energy etc.

Be low maintenance: automatic.

Be able to interact with physical environment context.

Be sometimes small enough so as to …

Be able to be encapsulated and embedded.

Be cheap to manufacture .

UBICOM: Human Computer Interaction

Basic concepts of HCI are:

Humans, Computers / devices and Interaction

Explicit HCI (eHCI): Explicit HCI (eHCI) design supports direct human intervention at set points during a device’s normal operation.

iHCI: Defined as “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”.

UBICOM: Smart Devices and Services

UBICOM smart devices and services are multi-purpose ICT devices, operating as a single portal to multiple remote vs. local application services. They are usually personalised devices, specified owner. Locus of control and user interface resides in the smart device. The main characteristics of smart devices: mobility, open service discovery, intermittent resource access. Important type of smart device is smart mobile device.

Here, we focus on design issues for the service model used by UbiCom Applications
