Engagement is the driving force behind all the Elements -- it surrounds and penetrates them, binding the experience together. -- jjg

Great talk about UX, 'cuz.

Amazing amount of thought in this... thanks!

If you'll excuse the toot, UX design as synthesis, gestalt, and orchestration of elements is how I've defined it for years now: uxdesign.com/ux-defined - in other words, I love it. Wonderful stuff, as ever.

As for "engagement" as the ultimate success metric, I can't say I'm completely on board. Not in all cases. Social app's, sure. Games, absolutely. For more practical applications (Quicken, etc.), though, less engagement might sometimes be more. There seems great danger, too, in equating experience design with art, such as Beethoven's. People experience everything. That doesn't make people who make everything UX designers. And designer's who blur the real distinctions between art and design risk losing the better part of each.

That said, as Joseph Campbell put it: "I don't believe people are looking for the meaning of life as much as they are looking for the experience of being alive." One thing that I agree makes people feel alive is flow ( en.wikipedia.org/wiki/Flow_(psychology) ) as defined in Mihaly Csikszentmihalyi's great book, Flow: The Psychology of Optimal Experience (1990)

Further food for though, I hope.

I'm 30minutes into watching this, hoping for some kind of value to emerge from this lecture.

Absolute trite.

It's lectures like this that make me hate the term "UX Designer." Its like you've coined a term for something that is common sense. It's lectures like this that make "UX Designers" seem comparable to someone taking the title of "Air Intake Specialist" for simply taking a deep breath.

I agree with 2 above comments - trite ^ trite.

There was nothing in this talk that would inspire me in any way, and the clips were too long and boring.

I won't work on any application using the 4 circle diagram thinking if navigation design was on the border of perception and cognition or maybe also emotion? Should we have a meeting about that? .. Totally over-enginneered subject..

oh my.. when the sound of Beethoven's symphony came out from my speakers I just felt something incredible . I was ready to cry..
thank's! very interesting material. Great presentation!

oh! And I see so many cooments from "well known UX designers"... Stick your ego in your ***

Great concepts, but from the first minute the sound of the man drinking water was so unpleasant and annoying that distracted me from the presentation. Be careful with those details!

Excellent presentation, Garrett.
I've searched many sites for getting the answer what is UX. and I found this one !

Your insights and diagrams are very impressive.
I've cited your diagram on my bolg as No.2 UX Diagram.

Thanks for sharing.

I think this may be a good video for beginners as an intro to UX. I didn't find it informative - I would have like to seen the presentation condensed into ~10 minutes.

P.S. the water gulping was a minor annoyance to me as well. =)

Great talk for beginners !

Designing interactions is an endeavour by human to implant predetermined forms of engagement in an interactive system in order to support the tasks its anticipated users are expected to accomplish using that system.

Similar to humans, the state of interactive systems is also dictated by the conditions of their existence. Subsequently designing interactions and experiences for an interactive system cannot derive from a realistic perception of that system unless the designer has an in depth understanding of the capabilities and attributes of that system.

Experiences do not just exist in the world freely; they are experienced through people encountering objects, events and mediums that carry them. In a chaotic complex system as our universe only an attempt can be made to embed predetermined states to change how we experience as to date we have not yet fully mastered all laws that govern the world.

Only in manmade digital systems this can touch the mastery surface of accounting for all possible inputs and outputs. And that is not possible without truly knowing the system, which is the medium itself.

I wished this man and his organization would have walked the walk instead of just talked the talk in this long video. I felt this man spoke and offered symbols of clarity and usability but demonstrated that he himself couldn't employ it as he couldn't present himself or the material in a user-friendly, clear and concise way... I mean if you want to offer a presentation about usability then be front-and-center as a person, lay things out clearly/quickly/succinctly then open it up to the users (the audience) for discussion/q&a. That would be in accordance with usability - user centric.
