"The right amount of technology is the minimum needed to solve the problem".Ĩ. Even when the battery dies, it will give me ample opportunity to do something about it before it actually happens, as the display dims gradually over weeks.ħ.
It either works or doesn't, no incorrect numbers reported, no missing functionality. "Technology should work even when it fails". The display on 12C is minimal but shows everything you _need_ to know: the single number in front of you.Ħ.
"Technology can communicate, but doesn’t need to speak". It respects that the user knows what they're doing.ĥ. 12C doesn't use ML to guess poorly what the user is trying to do, suggesting autocompletes and "are you sure" or "you mean.". "Technology should amplify the best of technology and the best of humanity". The functions in 12C are concise and operate quickly, showing the answer to one question at a time.Ĥ. When I'm discussing a scenario, I don't need to sit down at a computer and design a spreadsheet. "Moves easily from the periphery of our attention, to the center, and back". No notifications, input history, cloud saves, Share button, upsells, political statements or otherwise claim they're making the world better, achievements or pretty but functionless UI.ģ.
#HP 12C FINANCIAL CALCULATOR MANUAL SET ZERO PLUS#
Basic math plus special purpose finance functions. "Gives people what they need to solve their problem, and nothing more". I don't need to turn it off "correctly", I just turn it off.Ģ. I don't need to think about my 12C except when I need to answer a finance question. I don't need to worry about running out of battery or charging it, as I only need to once every few years. The display shows a single number: either the answer to your question or your current input. "Communicate information without taking the user out of their environment or task". The HP 12C is an excellent example of "Calm Technology":ġ.
