Clever idea, and (thank heaven) an incredibly clear demo right on the home page. Well done! I kind of think this could be like the next 2048.

PR: never blink royale

Same game, many more players at one time.

byronhsu1230 said 3 months ago:

Sorry, what did you mean?

GRiMe2D said 3 months ago:

There is a new trend on games – they are implementing "battle royale" genre where multiple gamers play against everyone at once and every "killed" player will leave the arena. Winner is who stayed as the last "alive" person.

PUBG probably was the first popular PC game that was battle royale. Fortnite is currently most played battle royale

Uh, what about Team Fortress 2 (King Of The Hill maps)?

NoodleIncident said 3 months ago:

TF2 doesn't have any BR modes. KOTH is a standard arena shooter mode, with teams and respawning; "KOTH" only signifies that the objective is to control a static area in the middle of the map.

The closest that TF2 gets to a BR is its "deathmatch" or "elimination" mode, I don't remember the name, in which there is no respawning and the last person standing wins. However, this is very different from a BR; the maps are still tiny, there is no loot to upgrade your character, and there is no "circle", which is a wall of damage that shrinks to force the remaining players to move towards each other rather than staying put.

Usually in TF2, there's teams and respawning.

For something that might be more applicable to your application, check out Tetris 99, which is a battle royale version of Tetris that Nintendo released earlier this year. Not only does it encapsulate an interface that might work better, but it also (as I understand it) thas mechanics to link you to other players in the set so there's a bit of 1-on-1 competition where people affect each other within the larger competition to last the longest.

I can imagine this being pretty fun if, for example you could also perform some task (answer a trivia question, move the mouse through a maze, etc) that might affect others (such as blank their video feed for a few seconds, or flash it white, or apply a weird color filter). The attention and concentration might make people forget to not blink, and the altering off opponents visuals could throw them off as well.

Instead of two players competing head-to-head, you could have many players connected to the same page, all competing.

However I assume I could out-blink the framerate of a laptop webcam ;)

Does closing one eye at a time count, or is this like Doctor Who and we just ignore the concept of winking?

StavrosK said 3 months ago:

You can't, and that's demonstrated in this thing I made for fun: https://youtu.be/xzcdopwq7ok

A frame is 40 ms and you blink for more than 100.

Too much effort. Just print out a picture of a person with open eyes.

At that point it's really just the honor code that holds us to honesty.

Are we so irremediably used to constant surveillance that the fact that a game would check my heart rate so I don't cheat doesn't trouble anyone?

To the extent that this seems an obvious and non-problematic idea to us?

Bah, I just tried it and it did not alleviate my urge to blink! I still want to blink afterwards. Does work it for you?

Trying to fool the blink detector might end up being more fun than not blinking.

byronhsu1230 said 3 months ago:

That's true. lol

mrguyorama said 3 months ago:

Do you really need it though? It would be pretty immediately obvious to the other player that their opponent is cheating.

byronhsu1230 said 3 months ago:

The detector model now is not strong enough. It uses traditional computer vision concept to detect the blinking. We plan to combine deep learning to develop a more robust detector model in the future.

jgtrosh said 3 months ago:

Also, to address winking: you could define blinking as a sequence of winks. This should accommodate people with 1 eye blind though.

Wait, do blind people win this 100%?

Vinnl said 3 months ago:

Do blind people not blink?

Edit: Figured I could look this up myself. As I thought, yes, they blink - blinking clears particles and such from your eyes. (That is, unless they have trauma that prevents them from blinking, of course.)

jgtrosh said 3 months ago:

Thanks, I didn't think to look it up. I must have recalled a case where the person had such trauma and extended that to blind people in general.

lostphilosopher said 3 months ago:

Looks like this drew some downvotes, but it gets a +1 from me. Reliable realtime "censoring" in video chat platforms _not intended for sexual content_ would make informal video chat a lot more user friendly. I'd totally video chat with random strangers, that sounds fun. I'd join a video chat group hangout (Hacker New Live, haha) but I'd prefer everyone kept their pants on. Doubly so if I'm going to join this chat at work or in public.

jasonjayr said 3 months ago:

Given what I know about the internet, this would promptly be subject to groups of users constantly testing it to see what they could get away with before it's the recognizer catches up.
