Pervasive Computing

1. Pervasive Computing
•Pervasive computing (also called ubiquitous
computing) is the growing trend towards
embedding microprocessors in everyday
objects so they can communicate
information.
•The words pervasive and ubiquitous mean
"existing everywhere.“
•Pervasive computing relies on the
convergence of wireless technologies,
advanced electronics and the Internet.

2. Pervasive Computing
• The goal of researchers working in pervasive
computing is to create smart products that
communicate unobtrusively.
• Pervasive computing is a rapidly developing area
of Information and Communications Technology
(ICT).
• Pervasive computing involves three converging
areas of ICT: computing (‘devices’),
communications (‘connectivity’) and ‘user
interfaces’.

3. Pervasive Computing
• The ultimate goal of “Pervasive Computing” is to
"make it unnecessary to carry around anything with
you.“
• Currently, we must carry many items including:
– Watch
– Wallet (money, credit cards, membership cards,
driver's licence, name cards, passes, tickets, ...)
– Cell phone
– Laptops, PDA's
– Documents
– Keys (for houses, cars, offices, ...)
• If computing becomes pervasive to its full potential,
there will be no need to carry these items at any
time.

4. Pervasive computing
• "machines that fit the human environment
instead of forcing humans to enter theirs."
