Most usability heuristics target screens. This set of 77 is built for physical and product design, a rare, evidence-based toolkit for the physical world.
These are 77 UX heuristics for physical and product design, drawn from the evidence-based design research of McKilligan, Daly, Seifert and Gonzalez. Classic heuristics (Nielsen’s 10, Shneiderman’s 8, ISO 9241) focus on digital interfaces; this set fills the gap for physical products. Use it as a menu of design moves to generate ideas and to measure a product’s usability, ergonomics and innovation. You do not have to apply all 77; pull the clusters you need.
Key takeaways
- Heuristic analysis is a core UX research method, and it guides usability testing.
- Common heuristics (Nielsen, Shneiderman, ISO 9241) mostly target digital design.
- This 77-item set is for physical and product design, useful with IoT and hardware.
- It comes from the paper 'Evidence-based design heuristics for idea generation' (Yilmaz et al., Design Studies, 2016).
- Treat it as a toolbox: pull smaller clusters, do not force all 77.

Yilmaz, S., McKilligan, S., Daly, S., Seifert, C. and Gonzalez, R. Evidence-based design heuristics for idea generation. Design Studies, 2016. The original set is 70 heuristics, with 7 that subdivide one of the others, totaling 77.
Mental shortcuts that capture strategies which tend to lead to workable solutions. In design, they are recurring moves distilled from many successful products.
Because most usability heuristics (Nielsen, Shneiderman, ISO 9241) target digital interfaces, leaving physical and product design without a shared, evidence-based toolkit. This set fills that gap.
No. Treat them as a menu. Pull smaller clusters relevant to your product’s usability, ergonomics or innovation goals.
From the paper ‘Evidence-based design heuristics for idea generation’ by Yilmaz, McKilligan, Daly, Seifert and Gonzalez, published in Design Studies in 2016.
Heuristic analysis defines the parameters you evaluate against, which then guides usability testing. It is part of any solid UX research toolbox.
