Nice idea!

I wonder if I print a set of open eyes and test your game.... Will it detect the trick? Would I win or get banned?

Jokes aside, eager to test ; )

Try doing one on a physical device too... My settings are just related to fade after reaching target or turn off immediately, Led colour (my ESP32 has a RGB onboard) and blink or pulse. Then there is a Start & Stop rate (150-60) as standard and IF sensor is connected or has data (heart) those values adjust too.

Nice one!

In my case v.1 and 2 were apps with a similar on screen red dot like yours. Much smaller and first placed at the status-bar (like the cock ":" blinking) then floating on screen lower left corner.

Things got interesting and worked best for me after I remove the light from the actual screen I must look at to work. Hence the device use, and then later the heart sensor.

The key (I guess) is to make you brain see it but not you (if that makes sense?). Something like you looking at your screen but can still see if an Ant moves nearby or your phone shows a notification. Near your screen but not on it ; )

In any case, great little test, and eager for any feedback you can get.

I make no claims here, I did it for me and looks like it works, not scientifically based or proven, not even tested on more than 1. So, no idea if can or will work for you ; )

That said, I'm now curious with so many comments to see how it will perform for those building versions to test. Its a 20min project, free for those already with prototyping board around.

The key for me was to remove to my marginal angle of vision, not on the screen (like an app), the moment I moved outside and wasn't in front of it it work best. If you see it directly it does distract you indeed.

Anything you get aware that goes fast-to-slow in a smooth gradient is the idea.

I tried sound (beats) on a headphone with some tracks, then build a tiny app to show pixels on the screen (blink) and then settled on a LED on a prototyping board type of device (ESP32) as a quick project and that worked.

I only improved by adding the heart sensor months later, now I don't think about it much, Now even If I'm not aware of, every time I turn the iMac it powers the device via the USB and so it starts anyway at 150bpm when the heart sensor is not responding or not detecting anything. After an hour it gets to 60 and the light fades out....

I'm not aware when it goes off, so I guess it is working ; )

Few people here posted code, ideas and I added the device pic I used (similar) and the sensors... you can buil one with almost anything and try!

Good luck!

We try estimate a "confidence" level when saying something, but NOT able to guess if a lie. An actor can easily have full confidence in a script, but still be a lie.

We intended for roles that are client facing and where personal skills are key. Things like retail, costumer service, sales.... not technically or education based, temporary work and alike. Not that Orwellian yet ; )

Example: You need 40 people for an event to work a few hours as guides or hosts, from 100 applying the system can suggest a score and list them all in order so you can start watching or calling for interviews from somewhere.

Jokes aside, whatever works...

For me a side device with a pulsating red light with a heart sync for the lope do the gig!

Deadlines comes free.

Nice one!

May do a pic later when back home, meanwhile... I used this ESP32 board, it has RGB LED right in the middle, here is a web picture of one: https://dfimg.dfrobot.com/nobody/wiki/8a1de42ec21a99f36f69da...

Its a Fire Beetle ESP32 E V.1.0, I bought cheap <$15 don't remember when or from who anymore... The heart monitor is from a study kit (Chinese brand)

My whole set is similar (not the same, not my picture) to this: https://pic-microcontroller.com/wp-content/uploads/2018/04/B...

Enjoy !
