Page Laubheimeris a former NN/G employee who worked on research, teaching, leadership, and design thought leadership. His expertise focused on web applications, AI, and projects in complex domains. His many research findings and recommendations were also informed by his background in library and information science, and his work often involved information architecture, navigation design, taxonomy construction, and ontology management.
Tree testing is a supplement to card sorting as a user research method for assessing the categories in an information architecture (especially a website IA and its proposed or existing navigation menu structure).
A treemap is a complex, area-based data visualization for hierarchical data that can be hard to interpret precisely. In many cases, simpler visualizations such as bar charts are preferable.
How to conduct user research for systems with confidential or otherwise sensitive data, for example in domains like healthcare or financial services, where it can be problematic to record screens or otherwise share the user's information.
Dropdowns, hierarchical menus, sliders, or scroll bars involve steering a pointer or a cursor through a tunnel; optimal design for these GUI elements should consider the Steering Law.
A key question in information architecture (IA) is to decide the number of items in navigation menus (including global menus and local menus). 4 main factors determine the answer, but it's not 7, despite a common myth.
A split button is a dual-function menu button that offers a default action as well as the possibility of choosing a different action by selecting from a set of alternatives.
