• FAHRENHEIT VS. CELSIUSKatey Deeny - US @followsprocess Director of Experience, WebMDSøren Muus - EU @sorenmuus Chief Creative Director, FatDUX
• A QUICK SHOW OF HANDS
• FAHRENHEIT AND CELSIUS Anders  Celsius,  1701  -­‐  1744   Daniel  Fahrenheit,  1686  -­‐  1736
• WHAT IS FAHRENHEIT? Boiling water 210° F Human body 100° F Freezing water 32° F Freezing Brine 0° F
• WHAT IS CELSIUS? Boiling water 100° C Human body 37,5° C Freezing water 0° C
• HOW DO THEY COMPARE? [°F] = [°C] × 9⁄ 5 + 32 [°C] = ([°F] − 32) × 5⁄ 9
• CELSIUS RELATES TO METRIC SYSTEM 1 Mean Calorie = 1⁄100 of the energy required to warm one 1 cm31 cm 1 gram gram of water from 1 cm 0 °C to 100 °C 1 cm 1 gram water = 1 cm3 1 kilogram water = 1000 cm3 = 1 liter
• FAHRENHEIT RELATES TO...Fahrenheit is not connected to anyother measuring system.It coexists but does not relate otherimperial measurement systems,often based on fractions such as 12or 16.
• WHAT TYPES OF SYSTEMS ARE WEDRAWN TO?EU seems to have affinity forstandards and abstracted, scientificsystems.US seems to have affinity fortraditional systems that arerepresentational.

• How do these differences affect interactions?REFERENCES, CONTEXT, & SYSTEMS
• SHARED REFERENCESAn important difference between UnitedStates and Europe is the degree andquality of shared reference to traditionaland contemporary culture
• SHARED REFERENCESWhat are shared •  Cultural References? •  Contemporary References?
• SHARED CULTURAL REFERENCES Present  day  peasants  in  Romania
• SHARED CULTURAL REFERENCESEurope •  A state of “tribal” nations •  Multiple languages •  8,000 years of co-existence •  Homogenous culture •  Common history •  Few words needed
• SHARED CONTEMPORARY REFERENCES Presiden@al  campaign,  New  Mexico,  USA
• SHARED CONTEMPORARY REFERENCESUnited States •  A nation of states •  One primary language •  ~250 years of co-existence •  Multicultural •  Diverse history •  Many clear words needed
• These shared cultural and contemporary references create…CONTEXT
• CONTEXT:UNIFIED EXPERIENCES
• CONTEXT:UNIFIED EXPERIENCESEurope •  shared cultural references } •  external contemporary referencesUS •  internal contemporary references •  language
• CONTEXT:DIVERSIFIED EXPERIENCES
• CONTEXT:DIVERSIFIED EXPERIENCESEurope •  language } •  internal contemporary referencesUS •  external contemporary references •  shared cultural references
• EUROPE IS TRIBAL(A STATE OF NATIONS)Europeans define themselves by whatthey aren’t (Americans) •  A spirit of self-sufficiency that keeps us from integrating the European nations.
• US IS SUPER-TRIBAL (A NATION OFSTATES)the US often define themselves by wherethey’re from •  “I’m irish-italian-danish-american”
• THE LANGUAGE OF INTERACTIONDESIGN •  HU: felhasználói élmény •  BL: потребителски  изживяване   •  HR: korisničko iskustvo •  IT: esperienza duso •  CZ: Uživatelský prožitek •  DK: Brugeroplevelse
• THE LANGUAGE OF INTERACTIONDESIGN •  How we signify something helps define it’s meaning •  Even when we have the words in English, we still keep DTDT
• References and context create the stage forSYSTEMS OF INTERACTION
• CREATION OF SYSTEMSThe context of unified/diversifiedexperiences creates a need for differentsystems •  US: affinity for traditional systems •  words, imperial measurements •  EU: necessity for common sense systems that unify •  numbers, pictograms, symbols
• MONETARY SYSTEMS

• EXAMPLES OF INTERNATIONAL IXDWhat makes them work ? •  They utilize shared references •  They fit into context •  They may feel “obvious” •  result of thoughtful design process •  iteration, refinement •  understanding of audience
• INTERNATIONAL TRAVEL SYMBOLS
• IKEA INSTRUCTIONS
• WASHING INSTRUCTIONS
• WHAT CAN WE LEARN?Audiences with narrow, deep knowledge •  There is almost always • a first time • a next time •  People are willing to learn •  Lengthy explanations not necessary
• WHAT CAN WE LEARN?Audiences with broad, thin knowledge •  Provide clear labeling and instruction •  Every time maybe a “first time” • ecommerce • information-based •  Rely on shared contemporary references when available
