Name the individual and research institute that collaborated with Douglas Engelbart to create the first mouse demo in 1964.
Bill English from Stanford Research Centre (SRC).
If a designer is doing precise CAD work, what DPI range should their mouse be set to, and why wouldn't a sensitivity over 1600 DPI be ideal?
CAD work requires 800-1200 dpi for high precision. Sensitivities over 1600dpi are intended for gaming and prioritize high-speed movement over fine control.
