  • Limited vision simulations

    WCAG reviews on screens are Velocity’s most popular review, but starting today, we are trialling personas to simulate the effects of visual impairment upon entire user journeys. In the short time we’ve been testing with personas that simulate limited vision, it’s been fascinating to see interfaces from a different perspective.   Consider this loading screen. A…

    If testing a user journey is as easy as a prompt, there is no excuse for no evidence in UX, even at the beginning.  Simulations are no replacement for human feedback; they are a useful stand-in when you otherwise have nothing and a bar raiser for all too seldom speaking occasions. AI simulations address: access…

  • Guide: Writing prompts for AI user testing

    prompting

    AI user testing identifies UX issues before human testing but a specific, actionable prompt is critical to achieve real insights. ‘Good’ Velocity prompts will constrain a simulation with specific testing goals for your design. Constraints are key since Velocity AI isn’t thinking; it is acting on what looks most likely based on patterns from millions…
