8. “The SPSS Processor is terminating due to a catastrophic error. Any working data file is lost. An attempt has been made to perform an input or output operation which is inconsistent with the mode of the file, e.g. direct access on a sequential file. This is a programming erro Restart the processor?”

24. Attention is simply the assignation of the mechanisms of analysis to a limited part of the perceptual field. (Neisser, 1974)

30. When I move files from the draft folder to the final folder, do they really move?

33. The mental model is knowledge of how the system works, what its components are, how they are related, what the internal processes are, and how they affect the components. Carroll, J. M., & Olson, J. R. (1987). Mental models in human-computer interaction: Research issues about what the user of software knows.

34. A model the user have about the system: What does it contain? Why does it contain it? How does it behave? Why does it behave this way? It enables the user to work with the system and give answers to questions like What will happen if I will press here? How can I … ?

36. When turning the mouse wheel forward (i.e. toward the table) what should happened zoom in or zoom out? The answer depends of the mental model you adopt. If it is a page that you have in mind, then it is zoom out, but if it is a camera, then it is zoom in. MS choose the camera mental model. About half of the world is paying the price MS choose the camera mental model. About half of the world is paying the price With WPF it is easy to solve the problem:

51. How can one use a smart tag in word editor using only the keyboard, not using the mouse?

52. Right click = Shift+F10

53. Press Alt+Shift+F10

54. The time needed to reach a target is proportional to the distance from the target and the size of the target t~d/s t = time to complete the action d = distance between hand (mouse) and the target. s = Target size

56. If you want to shorten operation time, Make the most used buttons bigger If you want to raise the features usage, Make the unused buttons bigger In both cases it might improve efficiency.

58. What do we change? Effect’s length Effect’s amplitude What is the direction? Usually down to zero But not always, like in the buttons size.

59. Will we lose the audience/ users/ rating? Is the answer different for leisure applications or professional ones?

60. Part 1 – There is a Chasm Part 2 – Tools to narrow the chasm Part 3 – The next step – Adaptive UI

64. The human brain is limited, but the demands are in constant progress – This is the usability chasm origin. A professional usability design may help narrowing the chasm. WPF make it even easier for the usability engineers:

65. By wisely using Color changes Size changes Movements We can manipulate mental models attention And get Enhanced Navigation Improved Dialog style Better Mental Models Clearer Visualization

66. Even if you used the tool wisely, you are trapped in the Novice – Expert dilemma: The effects help the novice, but annoy the expert We proposed the adaptive UX, as a solution. It helps in: Preventing the annoyance Improve efficiency (shorten operation time) Improve effectiveness (raising the feature use) In most cases effects should extinct with time/ usage This is only the beginning of correct use of WPF abilities, a lot more is expected in the next few years.
