Future of interfaces

• Being there– Sensory immersion– Natural interaction

• Entities– Virtual and physical ‘Things’

that represent computers

• Virtual common• Emotional feedback• Deeply-coupled systems• VIRTUAL FROGS

Not concerns

• Technology

• Human factors

19

IE/TC455 class #31

Interface challenges

• Just how much can we handle?

• What do we do with this ‘power’

• Is it truly empowerment?

20

IE/TC455 class #31

Concerns

• Social impact– Cellphones

– Headphones

– Eyephones

• Technology intoxication

• Kids and playgrounds

• Are we doing the right thing?

21

IE/TC455 class #31

Paradigm shift

• Socially responsible technologydevelopment & application

• Making a profit while solving pervasiveproblems

• Balance the ‘push’ & ‘pull’ of technologyand applications

22

IE/TC455 class #31

Problems we have to solve!

• Growth of population– hunger– Crime + terrorism– environment– energy

• Education of population– awakening children– life long learning

• Aging of population– Health maintenance– quality of life– pain management

Still….

• it’s fun to think about what we can dowith technology…– Visit the Science Fiction Museum

26

IE/TC455 class #31

Some advice…

• Don’t watch a lot of TV (or computer games)• Read the classics (it’s about the stories)• Go on some expeditions (get out there)• Work on real world problems• Help everyone to win• Count on serendipity

– …the faculty of making fortunate discoveries by accident.• Be generous = you only get to keep what you give away• Keep in touch!

“I hold the unconquerable belief thescience and peace will triumph overignorance and war, nations will cometogether not to destroy but to construct,and that the future belongs to those whoaccomplish most for suffering humanity.”

Louis Pasteur

The Long Quiet Highway…

"Whether we know it or not, we transmit the presence of

everyone we have ever known, as though by being in each

other's presence we exchange our cells, pass on some of our

life force, and then go on carrying that other person in our

body, not unlike springtime when certain plants in fields we

walk through attach their seeds in the form of small burrs to

our socks, our pants, our caps, as if to say "Go on, take us

with you, carry us to root in another place."

"The Long Quiet Highway" -- Natalie Goldberg
