Vasyl Mylko presented on 24,000 days of UX experience. He discussed the evolution of user experience from early concepts like the memex in 1945 to modern interfaces on mobile devices. He analyzed how top mobile devices adhere to Hick's law and Fitts' law, which relate user interaction time to the number of choices and size/distance of targets. While the iPhone revolutionized mobile UX, he found it no longer a killer experience and was surprised Google Nexus One didn't breakthrough. He believes the next phase of UX will involve nanotechnology and interaction with architectures.

3. 1942 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…" VannevarBush 1945

30. Gadgets and Mobiles

31. Killer Gadgets iPhone revolutionary mobile iPod Nano with click wheel

32. Modern Mobile UX

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

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

35. 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

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

37. Let’s check top mobiles against Hick’s law! Much choices 

38. Let’s check top mobiles against Hick’s law! Many choices  Much choices 

39. Let’s check top mobiles against Hick’s law! Many choices  Much choices  Not so many choices 

40. Let’s check top mobiles against Hick’s law! Many choices  Many choices  Much choices  Not so many choices 

41. What time does it take to move to click point?

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

43. 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.

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

45. Let’s check top mobiles against Fitts’s law! Small sizes 

46. Let’s check top mobiles against Fitts’s law! Tiny sizes  Small sizes 

47. Let’s check top mobiles against Fitts’s law! Tiny sizes  Small sizes  Big sizes 

48. Let’s check top mobiles against Fitts’s law! Tiny sizes  Small sizes  Small sizes  Big sizes  and pretty similar distances on all 4…

49. 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…

50. 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
