Course Introduction

Goals: This course provides a fundamental

knowledge for developing applications on mobile devices Smartphones: J2ME (Nokia S60 series),

Android, iPhone Pad computers: Android Tab/Pad, Apple iPad

Introduce basic concepts in mobile pervasive computing

The social impacts of smartphones.

Learn The Core

Learn to know, learn to do, and learn to be. The world and technology are changing so fast.

Learning method is important. The concept has not change very much.

Self-learning with guidance: Practice self-learning techniques by recognizing the

benefits. Be goal-oriented and set firm objectives. Motivate yourself by thinking of the benefits that

learning produces. Work at a steady pace. Ask questions, learn actively.

The world is not a desktop

Era of computing [Weiser, 1991] 1st Era: Many users one computer:

Ex: Mainframe 2nd Era: One user per computer: Ex:

personal computer 3rd Era: Many computers per one

user: Ex: cars, phones, watches, tab, routers, smarthomes.

In early days: tabs, pads, boards have been carefully researched.

Wireless networks accessible in everywhere.

Small but powerful devices can communicate to each other.

Mobile devices = Smartphones, PDAs and Tab computers.

Ubiquitous/Pervasive Computing

Ubiquitous ~ Pervasive ~ Everywhere Ubiquitous computing is bringing computers to live

in the real world with people. “The most profound technologies are those that disappear.

They weave themselves into the fabric of everyday life until they are indistinguishable from it.” [Weiser, 1991]

PerCom is oposite with virtual reality: VR puts people inside a computer-generated world

PerCom is a very difficult integration of human factors, computer science, engineering, and social sciences.

A good tool is an invisible tool focus on the task, not the tool. Eyeglasses are a good tool --

you look at the world, not the eyeglasses. [Weiser, 1993]
