Confirmation Responses: In-context, Visible, & Predictable Design versus Popup Windows.

Protecting users and the systems they use from slips is an open problem, which popup windows have not solved. We propose a new approach to action confirmation or cancellation based on three key design principles: in-context presentation, predictability, and visibility. In an experiment that compared an initial design based on this approach to traditional popup windows, this design reduced execution time without significant increase in slips. Providing information in accord with the proposed principles and application to preventing slips should be explored in future research.
