memex
“…Consider a future device for individual use, which is a sort of mechanized private file and library.
…
A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility.
It is an enlarged intimate supplement to his memory…"

Modern Mobile UX

What time does it take for me to want to click?

More choices I have – more time it takes
Reaction time, T
Low IQ
Avg IQ
High IQ
Probable choices, n

It is Hick’s law
T - is an average reaction time required to choose among choices
n - is a number of equally probable choices
b - is a constant that can be determined empirically

Let’s check top mobiles against Hick’s law!

Much choices 

Many choices 

Not so many choices 

What time does it take to move to click point?

The smaller item is –
the more time it takes
The bigger distance is –
the more time it takes

It is Fitts’s law
T - is the average time taken to complete the movement.
a - is an empirical constant represents the start/stop time of the device. b - is an empirical constant standing for the inherent speed of the device.
D - is the distance from the starting point to the center of the target.
W - is the width of the target measured along the axis of motion.

Let’s check top mobiles against Fitts’s law!

Surprised by results?
Windows Phone 7 has very promising UX!
iPhone did revolution in the past…
But it isn’t a killer mobile UX now. S60 5th has good ideas (haptic), but default screen UX isn’t good.
Google Nexus One disappointed me!
I expected UX breakthrough from them…

What is Next?
I had a chance to talk with one of Burj Dubai architects, in San Diego in July 2009…
about interfaces and interaction technologies
