    Mobile UX: Top 4 compared Mobile UX: Top 4 compared Presentation Transcript

    • which mobile UX rocks? Apple iPhone Google Nexus One Windows Phone 7 Symbian S60 5th
    • what time does it take for me to want to click?
    • more choices I have – more time it takes Reaction time, T Probable choices, n Low IQ Avg IQ High IQ
    • 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
    • let’s check top mobiles against Hick’s law! 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
    • 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
    • let’s check top mobiles against Fitts’s law! and pretty similar distances on all 4… Tiny sizes 
    • 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.
