Introduction

Question 1

The computer of the 21st century should be

Answer 1

• Helpful: Help you to do something
• Invisible: quiet and invisible
• unconscious: user can make more things by intuition due to computer

Question 2

What is a computer (past)

Answer 2

• Big
• Expensive
• Complicated
• General purpose (functionality depends on software)
• Isolated from others

Question 3

What is a computer (today)

Answer 3

• Smaller (portable)
• More powerful
• Cheaper
• Rather Generic (apps)
• More connected (sensors and networking)

Question 4

Trends that enable pervasive computing

Answer 4

From N:1 to 1:N (Users:Computers)

• Number of computers used increases
• Size and cost of computers decreases

Computing becomes omnipresent

• New materials; production techniques make components more energy efficient
• Lots of resources (processing smaller/faster/efficient, storage gets bigger and faster)
• Integration of Sensors and actuators in many devices
• Specialization
• Networking becomes omnipresent and more energy efficient

Question 5

The definition of pervasive computing

Answer 5

Also called “Ubiquitous computing”

• Describes that connected computers become interwoven with artifacts in our everyday life.
• Computing becomes an integral part of our daily life due to embedding of processing, sensing, activation, and communication into devices and environments

Question 6

The implications of pervasive computing

Answer 6

• Every physical object has a computer
• ubiquitous communication integrates all computers
• computers detect and analyze their surroundings
• applications adapt automatically
• user controls these systems implicitly

Implications on:

• Security
• Ethics
• Human Computer Interaction
