27. Multiple Monitors<br />Is something like this available? Fresnel lens?<br />
33. What time does it take for me to want to click?<br />
34. More choices I have – more time it takes<br />Reaction time, T<br />Low IQ<br />Avg IQ<br />High IQ<br />Probable choices, n<br />
35. It is Hick’s law<br />T - is an average reaction time required to choose among choices<br />n - is a number of equally probable choices<br />b - is a constant that can be determined empirically<br />
36. Let’s check top mobiles against Hick’s law!<br />
37. Let’s check top mobiles against Hick’s law!<br />Much choices <br />
38. Let’s check top mobiles against Hick’s law!<br />Many choices <br />Much choices <br />
39. Let’s check top mobiles against Hick’s law!<br />Many choices <br />Much choices <br />Not so many choices <br />

41. What time does it take to move to click point?<br />
42. The smaller item is –<br />the more time it takes<br />The bigger distance is –<br />the more time it takes<br />
43. It is Fitts’s law<br />T - is the average time taken to complete the movement.<br />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.<br />D - is the distance from the starting point to the center of the target.<br />W - is the width of the target measured along the axis of motion. <br />

49. Surprised by results?<br />Windows Phone 7 has very promising UX!<br />iPhone did revolution in the past…<br />But it isn’t a killer mobile UX now. S60 5th has good ideas (haptic), but default screen UX isn’t good.<br />Google Nexus One disappointed me!<br />I expected UX breakthrough from them…<br />
50. What is Next?<br />I had a chance to talk with one of Burj Dubai architects, in San Diego in July 2009…<br />about interfaces and interaction technologies<br />
