What are design strategies for displays? |
Units of Measure/Actual Values - Full value (not x 100) Natural Up/Down, Left/Right - Using up/right for increase, left/down for decrease etc. Critical within view - Critical information is in view Delineate when value is off-nominal - A red section for high etc. Perpendicular View - Displays should be perpendicular to worker line of sight |

What are design strategies for controls? |
Design to Expectations - Controls should operate according to real world expectations (turning right should increase etc.) Provide Incremental Markings - Don't just show the bounds of feedback (temperature should show changes incrementally as control changes) Functional Consistency - Adjacent controls act the same. Example: light switches next to each other should act the same Minimize effort - Don't make someone turn a control numerous times for minor changes Minimize Accidental Activation - Make controls easy except when it's necessary to prevent accidental activation

What are design strategies for labels? |
Capitalization - All caps for acronyms and important labels (EMERGENCY). Each Label word should be capitalized Label Length - Too many words detracts from the label Label Clarity - Design labels with novice users in mind.
