  • Re: Visual closing speed

    I have run across a reference to the limit of human perception as 25 - 30
    milliradians per second for persons to discern closing speed on objects.
    The reference is

    Plotkin, S. C. (1976) Accident and Product Failure Analysis. Oakland, CA
    Syllabus

    Can anyone direct me to the source of this material or any other sources for
    this data?
