Need help for my final year project

Projects General Guidance
1

I'm really new to arduino, last i posted in this forum are about a project that requires sensors to detect congestion but i found out it was too ambitious at my level.

So i want to ask again does grouping people based on colors (colour of their shirt) using color sensor works? the problem statement i've been given is to solve stampede accident so im thinking by using color sensor that detects which group gets to go first can reduce congestion. I got the idea from a youtube idea and i think its doable. But before i proceed i want to hear some of you guys thoughts

Your topic was MOVED to its current forum category as it is more suitable than the original

...yikes.

oh no i just realised the poor choice of words. but no what i meant is lets say if you wear red shirts then they get to go first

Not exactly a simple project - how would a simple light sensor know if the thing it's pointed towards is a t-shirt (or any kind of clothing, for that matter)? Leaving aside that a shirt isn't a blob of solid color, but reflects light and what the sensor sees may differ due to angle of impact (remember, people are 3D) or distance of the wearer. Doesn't mean it's impossible, but getting it to work properly and reliably is probably going to be somewhat fiddly. And your sensor will get confused by people with red umbrellas, backpacks, handbags, brochures, ...

("Final year" of what? High School? Undergrad?)

im an undergrad. We are asked to come up with prototypes that are going to solve the problem. Do you have discord? i think i can explain it better

Is your problem just "make sure that only X people go through the gate per Y minutes"?

The simplest solution to this problem, in my opinion, would be to give people a ticket with a date and time printed on it, along with a QR code which encodes said date and time (plus, if you're paranoid, a cryptographic signature). QR codes are reasonably simple to read even on garbage cameras so I'd wager solutions like this are actually in use for actual places in the real world. That'll be both easier from a software engineering standpoint, and more reliable.

Is the idea to prevent stampedes, or do something about a stampede that is already happening?

If it is happening, do not expect people to act rationally.

It would be entirely unreasonable to expect an undergrad (in any field) to "solve" a stampede / mass panic in progress - as far as I know, even the experts in this field mostly focus on risk assessments and prevention as there is very little you can do once they have started.

Thanks for providing your opinion on the supervisor's thinking!

11

It's my opinion on your hypothesis about what the supervisor may have been thinking, but you're welcome anyway.

12

Right.

Was "Arduino" - or indeed, computers of any sort - part of the specification? :thinking:

May indeed be an "XY Problem"?

Need to describe the actual project specification in far more detail. :grin:

13

A problem like this would be so much easier if only the CV-19 vaccine actually had tracking chips (the power supply and antenna for such also) that we could exploit for a crowd control system.

Maybe next pandemic??

14

In advanced countries, nearly everyone now carries a tracking device with them everywhere, tracking every movement, all the time.

They are variously called "cell phones", "handies", etc.

15

In what?
