Does anyone else notice that there is enough of a delay for you to switch your choice after the computers choice is displayed allowing you to get a 100% win rate.

I can't wait for someone to make a sign language browser interface out of this. I'm sure things like that have been done with desktop accessibility apps, but embedding it into a web page or browser plugin would be amazing.

Which reminds me... I saw a funny trick once. Probably impossible through network, but there was an implementation that would always win, no matter what you'd choose. The secret was, image recognition was instantaneous and showed winning hand on the screen so fast that human assumed it is fair play. At the beginning you'd thought they are lucky. After few games - they have a good prediction algo. But after some time you feel weird. Of course people guessed sooner or later, but it was funny anyway.

I love it when I win because it misinterpreted my paper as scissors.

Seems to be mis interpreting my hand signals around 5-10% of the time. The little icon flickers rapidly between correct hand signal & the "face" icon, and I tried holding my hand closer to the web cam which didn't seem to help. Very cool though.

I&#x27;d love to see this combined with <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=3nxjjztQKtY" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=3nxjjztQKtY</a> for a bot that always wins without a perceptible delay.

So, my 8 and 10yo sons and I just started playing again once we were introduced to Rock Paper Scissors Lizard Spock from Big Bang Theory.<p><a href="http:&#x2F;&#x2F;www.samkass.com&#x2F;theories&#x2F;RPSSL.html" rel="nofollow">http:&#x2F;&#x2F;www.samkass.com&#x2F;theories&#x2F;RPSSL.html</a> <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=Kov2G0GouBw" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=Kov2G0GouBw</a>

It reminded me of <a href="http:&#x2F;&#x2F;www.nytimes.com&#x2F;interactive&#x2F;science&#x2F;rock-paper-scissors.html" rel="nofollow">http:&#x2F;&#x2F;www.nytimes.com&#x2F;interactive&#x2F;science&#x2F;rock-paper-scisso...</a> a game illustrating how simple AIs strategy(er, algorithms)) can win in well over of 50% of the cases ; but it&#x27;s unplayable now in the post-Flash era.

Why is it just a red box in the latest chrome?<p><a href="https:&#x2F;&#x2F;puu.sh&#x2F;xaaCh&#x2F;cae3f64840.png" rel="nofollow">https:&#x2F;&#x2F;puu.sh&#x2F;xaaCh&#x2F;cae3f64840.png</a>

This is hilarious and awesome. I&#x27;m reminded of the great Simpsons exchange:<p>Lisa: poor predictable Bart, always chooses rock<p>Bart: ah, good ol&#x27; rock. Nothing beats that!

Where can I find the training data&#x2F;sample code for training a similar rock-paper-scissors network myself?

I&#x27;m getting a really high misclassification rate on what it says I&#x27;m throwing. Cute idea, but didn&#x27;t work for me..

&gt; Unfortunalely, your browser doesn&#x27;t support accessing your webcam.<p>This is in Safari — is this really the case? I&#x27;m not a web dev, so I don&#x27;t really know, but AFAIK Safari can do web cam. And if not now, they should support WebRTC in High Sierra, correct?
