Hi there,
I have experience in building such system.
One system that I built for a client had a embedded system in it, in which customers would stand in front of the screen and could change their dresses in the camera, it was based on Microsoft Kinect, we can do something similar, but only software, as embedded hardware will attract more time and money.
I am professional with my work and have recently started on freelancer, my work's quality would be top notch and I would deliver the project on time.
Thanks.
