      Does anyone in the NYC area have a pre-2000 PC with CRT I use to do some input-to-screen latency measurements?

      So far, I've tested or can test a Commodore PET, SGI indy, Symbolics 3620, Next cube, Mac classic, and Apple II, plus some modern machines.

      Unfortunately, old PCs seem to be in a sort of uncanny valley where they're too slow to be useful and too mundane for people to collect.

      Also, does anyone near NYC have a phone I can use for latency/responsiveness benchmarking, esp. an older iPhone?

      I've started doing basic latency measurements on phones and haven't found and iPhone that's slower than any Android phone.

      I'm curious if an iPhone or iPhone2 is quicker than a modern Android phone at scroll and/or tap responsiveness.

      I've started measuring keypress -> USB latency with a logic analyzer and I'm seeing some measurements in the 20ms to 30ms rangepic.twitter.com/nzUPYMS2rn

          Is this plausible? 20ms to 30ms for a keypress seems absurd. OTOH, it's consistent this person's experimenthttp://forums.blurbusters.com/viewtopic.php?f=10&t=1836&sid=080b1b6a517ed1eb6988627c48da080c&start=10 …

          They start measuring from internal switch activation and I start when the key moves, so that could explain the 10ms difference.

          Also, does anyone in the NYC area have an "interesting" keyboard I can borrow to test?

          So far, I've tested a couple gaming keyboards and a bunch of other "normal" keyboards. The gaming keyboards haven't been faster.

          I would kill for a comparison to an Arduino Leonardo emulating a keyboard.

          😱 thank you for doing this! I think this issue is much more interesting and important for the UX than e.g. improving the UI of an editor 😁
