Hi everyone,

I’m building a project to detect work errors in a warehouse. The goal is to check if an employee follows the correct sequence (e.g., Pick item → Press button → Place in bin).

This requires detecting both the person’s actions (using their pose) and the objects they interact with.

For this combined task, what is the recommended **Project Type** in Roboflow? Is **Keypoint Detection** the right choice because it supports both pose skeletons and simple object bounding boxes?

Thanks for any advice.

Hello @jao_ICE

If your use-case is simple, having one KeyPoint Detection project and model which does both (pose + object detection) makes sense. If you also want to detect individual products (toothpaste, toilet paper, etc), it will make sense to have separate projects; one object detection project and one keypoint detection project.  
You can then use both [models in a workflow](https://docs.roboflow.com/workflows/what-is-workflows) to solve your problem of checking if an employee follows the correct sequence.

Hope this helps you get started with your exciting project!

Hi Jeremy,

Thanks for the very helpful information! I have a follow-up question. Could you please let me know approximately how many images are needed to train the model for workflow error detection?

Thanks,

jao ICE
