A Closer Look

  • What?


Study context

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


Semiotic engineering

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.”

  • Whenusers do not understand the message a communicationbreakdowntakesplace


Semiotic inspection method

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


Procedure

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


Sample findings

MedInfo2013 Olof Torgersson 9

SampleFindings

  • Metalinguisticsigns

    • Busyprofessionals

    • Interest in adaptingthe system

    • Extensive instructions & lack ofinstructions

  • Staticsigns

    • Irrelevant information

    • Lack ofsignifiers


Sample findings1

MedInfo2013 Olof Torgersson 10

SampleFindings

  • Dynamicsigns

    • Assumesusersknowwhatto do

    • No guidance

    • No indicationof order

    • Lack of feedback


The communication message

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


Comparison

Comparison


Discussion

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
