There is a sizeable literature on Human-Machine Interaction, HMI. It is an entire multidisciplinary field. Some people like to call it Engineering Psychology, some people Cognitive Science, others just Human Factors. There is a Human Factors and Ergonomics Society, which has members from all over the world, and runs an annual European conference Its journal, Human Factors, has been established for many decades. Just for computers (HCI), there are ACM Transactions and an annual ACM conference. There is an annual UK BCS conference. In aviation, there is

Besides Don Norman's classic, which is not a text, Chris Wickens has a well-established text on Engineering Psychology which is also not domain specific. Harold Thimbleby has a prize-winning text on HCI called Press On. Harold works primarily with medical devices, not process control.

The word "error" is value-laden. If there is not an "error" then everything is alright - not......

You don't say what you have in mind with TMI. There were features that contributed to the operators' misunderstanding the actual situation. There can be plenty of those without overt errors.

One of the classics in plant control is putting key indicators in a position where an operator sitting at hisher intended position (usually a "console") cannot see them.
