Former NASA engineer turned YouTube science fun guy Mark Rober explained this attack in 2014 https://www.youtube.com/watch?v=8Vc-69M-UWk https://www.youtube.com/watch?v=8Vc-69M-UWk and references this 2011 UCSD paper Heat of the moment: characterizing the efficacy of thermal camera-based attacks https://dl.acm.org/citation.cfm?id=2028058 https://dl.acm.org/citation.cfm?id=2028058 So not sure what the Thermanator folks are adding here... EDIT: Thermanator paper cites the UCSD research, focuses on qwerty keyboards, updated technology for thermal cameras, comparisons to other attack vectors for public password entry (when you are at coffee shop, airport, ATM etc.).
