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…..

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 .

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 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

Ubiquitous computing (ubicomp) is a post-desktop model of human-computer interaction in which information processing has been thoroughly integrated into everyday objects and activities. In the course of ordinary activities, someone “using” ubiquitous computing engages many computational devices and systems simultaneously, and may not necessarily even be aware that they are doing so.
