UseMay

UseMay is a design principle in human-computer interaction and software development that emphasizes conditional activation of features based on a user’s expressed willingness to engage. It contrasts with features that are always available (use-must) or that operate strictly by default. UseMay advocates presenting options in a staged manner, often with explicit consent flags or contextual prompts, to respect user autonomy and reduce unwanted actions.

Mechanisms associated with UseMay include progressive disclosure, explicit opt-in checks, and contextual prompts that appear when the system anticipates user engagement or when the user initiates a request. The aim is to lower cognitive load and minimize interruptions by avoiding unsolicited actions while keeping essential functionality reachable through deliberate choices.

Designers must balance clarity and friction: communicate what happens when users consent, provide easy reversal, ensure privacy-preserving defaults, and consider accessibility. Performance implications and localization should also be considered, as delayed prompts can affect perceived responsiveness.

Applications of UseMay include privacy-sensitive data collection, adaptive feature suggestions, and assistive interfaces in which the system offers capabilities contingent on user consent or demonstrated interest. Critics warn that excessive conditional prompts can fragment the user experience, reduce consistency, or erode trust if not clearly explained.

Related concepts include consent management, progressive disclosure, opt-in versus opt-out, adaptive interfaces, and the broader goal of upholding user autonomy in design.
