L1 SUMMARY OF SYSTEMS

Question 1

The ubiquitous computing vision of Mark Weiser?

Answer 1

• He envisioned a world where computing and applications are embedded in everyday objects like cars, televisions and clothes.
  • Each person is continually interacting with hundreds of interconnected computers that weave themselves into the fabric of everyday life until they are indistinguishable from it.

Where virtual reality puts people inside a computer-generated world, ubiquitous computing forces the computer to live out here in the world with people.

Question 2

The trends that make ubicomp possible?

Answer 2

• miniaturization
• communication and networking
• AI
• materials science (smart materials, better batteries, biofuels)
• multimodal human computer interaction.

Question 3

What are the waves in computer technology evolution?

Answer 3

Mainframe, personal computing, ubicomp

- Tabs are wearable centimeter-sized devices
- Pads are hand-held decimeter-sized devices
- Boards are meter-sized interactive display devices
