Computing: The TrendOne computer for many people

One computer for each person

Many computers for each person

Course Outline-4

As the Trend Goes ..

Dust can compute and communicate!

請掃床底下，我們有三吋厚了！“Smart” Dust

Course Outline-5

When Everything Smart ..

and Communicating

Computing BecomesUbiquitous!

Computing BecomesUbiquitous!

Course Outline-6

Ubiquitous Computing Environments saturated with computing and c

ommunication capability, yet gracefully integrated with human users

- M. Satyanarayanan People and environments augments with com

putational resources that provide information and services when and where desired

- Mark Weiser Computing and communicating everywhere a

nd always

Course Outline-7

Imagine … What could happen when things are

connected? And connected to the Internet?

Course Outline-8

Requirements Things must be smart …

small, cheap, mobile processors, with sensors, actuators, and networking

in almost all everyday objects,including on our body(“wearable computing”)

Real world objects areenriched with informationprocessing andcommunicationcapabilities

Course Outline-9

Requirements Things must be smart …

Smart and smarter

What makes it smart?

Course Outline-10

Requirements (cont.) Things are connected …

wireless, most probably to the Internet to form a smart space/environment and is linked to the cyberspace

access to virtual world, virtual counterpart, augmented reality

Course Outline-11

But, What If All Things Were Smart?

Course Outline-12

Consequences Indistinguishable and more tightly

integrated physical and virtual worlds Scarcest resource:

human attention

Course Outline-13

Good Technology Is Invisible “Invisible” stays out of the way of task

Like a good pencil stays out of the way of the writing

Like a good car stays out of the way of the driving Bad technology draws attention to itself, not

task Like a broken, or skipping, or dull pencil Like a car that needs a tune-up

Computers are mostly not invisible They dominate interaction with them

Pervasive computing is about “invisible computers”

Course Outline-14

Mark Weiser (1952 –1999), XEROX PARC “In the 21st century the technology revolutio

n will move into the everyday, the small and the invisible…”

“The most profound technologiesare those that disappear.They weave themselves into thefabrics of everyday life until theyare indistinguishable from it.”e.g., motors

Pervasive Computing Vision

Course Outline-15

Invisible/Disappearing Computing Clam, non-intrusive, disappearing, proactive Information processing moves to background

Human centered: concentrate on task, not tool Computing as an invisible, ubiquitous,

autonomic background assistance Specialized, invisible computers will become an

integral part of the nature human environment “Computing without computers”

Adaptive, self-healing, self-managing, ... Natural human interfaces (speech, gesture)

interact with real objects, not computers
