Show HN: A new kind of FPS aim trainer

I played a lot of Valorant and got mad, so I made an aim trainer that analyzes your raw crosshair movement to explore your raw motor and perceptual weaknesses instead of scoring scenarios. It also chooses sens and difficulty as part of the tasks, and makes playlists that are optimal difficulty for you to learn and progress faster!

The aiming is very choppy because it feels like my cursor is "on rails", or stuck in some kind of grid. Not representative of any modern shooting game I've played. I think this would teach the wrong habits if someone were to use it as an aiming coach.

Are you using it on chromium? It's the only browser I get raw mouse events from right now, so other browsers tend to be more choppy.

As for the habits, the point of this program is that it ultimately admits that far domain transfer for aim trainers is difficult regardless of what you do, so it tries to optimize in an absolute sense your motor control over your mouse. That way, regardless of scenario you'll have smoother and more efficient aim.

So cool! but somehow the simulation does not work on firefox. the crosshair is just stuck in the middle

pmazumder•18 minutes ago

It should still work on firefox, but the experience will likely not be as good. Chromium is the only browser engine (as far as I know) that gives me access to raw, unaccelerated mouse events, so it's the smoothest experience.

Even with "reduce motion" enabled the background of this page is constantly animating - it's so distracting I just gave up.

I didn't realize it could be distracting, sorry. It shouldn't happen now

I enjoyed this. Does the same theory apply to a gamepad? My intuition says yes but curious what you think

pmazumder•15 minutes ago

I imagine it would generalize well to any fine motor control task with a defined tracking objective. The literature I reference mentions that human error when steering cars also roughly follows the same distribution.

Haven’t had the chance to use it use it yet, but the writeup on it is super cool.

Encourage anyone to check it out

Interesting project! I am relatively skilled at FPS with a mouse, but would like to improve with my trackball (so that I don't have to change my setup when playing an FPS). This could cone in handy, though I imagine that there aren't multiple "mouse profiles" built-in? It could be useful for players to understand how much of a difference different mice make.

pmazumder•about 1 hour ago

Hi, thanks for the feedback! Multiple mouse profiles isn't something I considered, but I'll definitely look into it. I know a lot of FPS gamers are super particular and switch between mice/mousepads/skates constantly, so it would probably help to provide a semi objective measurement of what setup they're doing best on as well

CS 1.6 scouts and knives was the ultimate aim trainer

woah, so many memories bubbling up right now, thanks!

You might want to look into this page - it slows my PC to a crawl :-(

pmazumder•23 minutes ago

What browser are you on? Hardware acceleration? It shouldn't be very difficult to run, so I'm guessing some sort of a compatibility issue

Sorry, the linked page, not the actual app. It slows my PC to a crawl.

Interesting project. One suggestion I'd make is to reduce the configuration complexity up front on new users. It is kind of overwhelming before you have a feel for how your settings translate to the actual training experience.
