Which of these two methods of displaying data is 60,000 times faster than the other:
Method 1
Method 2.
_________________________________________________________________________________
Although both methods convey the same information, 3M Corporation has performed studies that indicate that the human mind can process the graphical display of information delivered by the airspeed gauge 60,000 times faster than the same information presented in the second method above.
In method 1, not only can you tell at a glance how fast you are going, you can also tell how fast you are going in two different measurement units, in this case, Miles Per Hour and Knots.
Because the gauge incorporates color, you also know you are going too fast with regards to the aircraft's speed limitations and how much you must adjust your speed in order to bring the airspeed within allowable limits.
In short, you have a feedback loop already designed into the use of the gauge. In method two, you have no idea how fast you need to be going.
Now let's take a look at a dashboard, using both gauges, interactivity, alerts, and various types of graphs.
