In this book the author discusses the responsibility of a failed interaction. Does it lie on the user or does it lie on the designer? He starts with using the example of doors. While reading this example, I remembered a very similar case which led to deaths of many people because of bad design.
Unfortunately, I could not unearth the details of this specific flight crash. However, from what I remember, the pilots were not able to notice the drop in altitude because the display on the panel. There were three issues :
- The display was not visible to the eye and it was placed in a way that faced away from the pilots direct line of sight
- There was no indication or warning of this sudden altitude drop in any way – red light, sounds
- The display on the panel was not clear and confusing to read.
Many ten to blame it on the carelessness of the pilots. However, it is important to consider that the design of this small but non-trivial feature could have prevented this.
