### Mobile UX: Top 4 compared

1. 1. which mobile UX rocks? Apple iPhone Google Nexus One Windows Phone 7 Symbian S60 5th
2. 2. what time does it take for me to want to click?
3. 3. more choices I have – more time it takes Reaction time, T Probable choices, n Low IQ Avg IQ High IQ
4. 4. 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 it is Hick’s law
5. 5. let’s check top mobiles against Hick’s law! Many choices 
6. 6. what time does it take to move to click point?
7. 7. the smaller item is – the more time it takes the bigger distance is – the more time it takes
8. 8. 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.  it is Fitts’s law
9. 9. let’s check top mobiles against Fitts’s law! and pretty similar distances on all 4… Tiny sizes 
10. 10. surprised by results? Windows Phone 7 has very promising UX! Google Nexus One disappointed me! I expected UX breakthrough from them… iPhone did revolution in the past… But it isn’t a killer mobile UX now. S60 5 th has good ideas (haptic), but default screen UX isn’t good.
