Hi @paula_dambrosa, n00b here :), so I may misunderstand what you have in mind. Perhaps, you are thinking of product and industrial design in terms of IoT, wearables etc.? Service design and visual merchandising might be of interest too.
I have a Safari membership, which I find quite useful. I am currently reading Smart Retail by Richard Hammond. He briefly touches on A/B Testing in a physical retail environment. I am still reading the book so maybe there are other things that sort of relate to what you are interested in.
Other design books in my Safari queue are:
Service Design for Business by Ben Reason et al.
This Is Service Design Doing by Marc Stickdom et al (raw & unedited version so most chapters are missing)
X: The Experience When Business Meets Design by Brian Solis
The Art of Product Design: Changing How Things Get Made by Hardi Meybaum
Designing Connected Things by Alfred Lui et al. (IoT related)
Value Proposition Design: How to Create Products and Services Customers Want by Alexander Osterwalder et al.
I don't know where you're located but if you're in Australia but this might help:
If you're in Australia, The Big Life Fix with Simon Reeves is on SBS tonight at 8:30pm. If you're in the UK, you are probably able to watch this via the original broadcaster's website. This week's episode:
Seven of the UK's leading engineers, designers and computer programmers put their skills together to try and help four people with very different needs. Mum of two Shamreen has very limited vision, and needs something that will help her and her two young sons get around. Seven-year-old Rosie had brain surgery as a baby and now wears a cumbersome medical helmet, hopes the team can make her a less visible helmet that will help her fit in with her friends, and the team are challenged with coming up with a solution to help two teenage brothers with cystic fibrosis.

@HAWK, thanks for the link. I'm in the process of reading it.
