Workhorse, data-dense digital products pose serious challenges, requiring compact UI focused on productivity and efficiency. To make better complex apps and software, we must deeply understand the domain expert power user, whose behavior and preferences confound the best digital product designers. Mission-critical app users demand compact, crowded interfaces that only a master Excel ninja could love (or use). Welcome to endless data, filters, sorting, tabs, drop-downs, modals, buttons, and voluminous grids. It can be brutally difficult to make user-friendly interfaces for expert users with deep domain knowledge. Most complex digital products are not known for their stellar UI. But you CAN do it. The best place to start is understanding the user of complex interfaces. In this session, you’ll learn the tips, tricks, and indispensable secrets to help you understand them. These principles will change the way you think about constrained interface design. And your power users will love you for it.
