104 Progressive Disclosure
A method of managing complexity, in which only necessary or requested information is displayed.
• Progressive disclosure is used to prevent information overload and provide step-by-step guidance. It involves separating information into layers, and only presenting layers that are necessary or relevant.
• Progressive disclosure is used in user interfaces, instructional materials, and the design of physical spaces. It can also be applied to differentially support users of different skill levels; for example, displaying advanced features to advanced users only.
• Use progressive disclosure to reduce information complexity. Consider hiding infrequently used controls or information, but make them available through simple requests, such as pressing a “More” button. When procedures are sensitive to error, use progressive disclosure to lead novices through the procedure step by step.
