  2. MedInfo2013 Olof Torgersson 2 The System

  3. MedInfo2013 Olof Torgersson 3 A Closer Look • What?

  4. MedInfo2013 Olof Torgersson 4 StudyContext • Computerized Patient Record System for dental care • Widelyused by public dental care in Sweden • Major upgradecaused a lotofconfusion • Evaluation • Workplace studies – University of Skövde • Expert evaluation – Chalmers • Heuristicevaluation x 2 • Enhancedcognitivewalkthrough • Predictiveuseerroranalysis • Semioticinspectionmethod

  5. MedInfo2013 Olof Torgersson 5 SemioticEngineering • Clarisse Sieckeniusde Souza, 2005 • Focus on signs and theirmeaning • Interface message from designer touser • Designers communicatethrough the interface tousers • Communicability “Here is my understandingofwhoyouare, whatI’velearnedyouwant or needto do, in whichpreferredways, and why. This is the system that I havethereforedesigned for you, and this is the wayyoucan or shoulduse it in order tofulfil a rangeofpurposesthat fall withinthis vision.”

  6. MedInfo2013 Olof Torgersson 6 SemioticEngineering You do not careabouticons, so therefore I useonlyone • Whenusers do not understand the message a communicationbreakdowntakesplace

  7. MedInfo2013 Olof Torgersson 7 SemioticInspectionMethod • Analyze 3 typesofsigns • (1) Metalinguisticsigns • (2) Staticsigns • (3) Dynamicsigns • Contrastivecomparisonofresults from 1-3 • Identify problems & lack ofconsistency • Summarize – describe the message • Conclusiveappreciationof the qualityof the designer-to-usercommunication

  8. MedInfo2013 Olof Torgersson 8 Procedure • Observation • Scenario • Anna is a fifty years old dentist whoworks in a bigger dental clinic…. Anna has many patients booked for eachday and sheneedstoworkquicklyto be abletoexamine and treat the patient as well as toinsert the data about the current and futuretreatmentinto the CPR system… • Describe tasks toevaluate (10) • Openingthe medical record of a specific patient. • Makinga new healthdeclaration. • Sendinga referralto oral surgery. • … • Repeatedinspectionof the signs in all parts

  9. MedInfo2013 Olof Torgersson 9 SampleFindings • Metalinguisticsigns • Busyprofessionals • Interest in adaptingthe system • Extensive instructions & lack ofinstructions • … • Staticsigns • Irrelevant information • Lack ofsignifiers • …

  10. MedInfo2013 Olof Torgersson 10 SampleFindings • Dynamicsigns • Assumesusersknowwhatto do • No guidance • No indicationof order • Lack of feedback • …

  11. MedInfo2013 Olof Torgersson 11 The Communication Message • Usersareexpectedtohaveadvanced digital skills and clinicalknowledge • Assumed order throughtabs • General • Additional info • … • Basic planning • Some order in toolbars • Overall inconsistent

  12. MedInfo2013 Olof Torgersson 12 Comparison

  13. MedInfo2013 Olof Torgersson 13 Discussion • Wantedto show problems withflow and wayfinding • Focus on 3 different typesofsigns • Helpedtoreflect on what text, iconsetcactuallycommunicate • Clearly not consistent • SIM includes manuals etc, interestingaspect • Large system • Lots of data • Methodcouldgivemore support • Moreabout overall qualitythanothermethodsbut not enough
