1 Lean UX Lean UX

2 Preconditions Already existing Determination of provider goals Definition of target groups Personas Goal to get clear ideas about the circumstances the application will be used in Lean UX

3 Situation Interactive Applications continue to migrate into our physical environment. We use them in a myriad of locations and a broad variety of circumstances That might be mobile devices But even more wearables embedded systems Internet of Things Lean UX

4 Task Find and select the most appropriate interaction modality according to User environment constraints. Lean UX

5 Related Questions What hardware is used/available? Which Interface Options come with it? Are there any specific room situations (physical environment) (Light / Brightness, Moisture / Humidity, Noise etc.) Do there exist Restrictions for the user? (Gloves, environmental influences, visibility conditions etc.) What s the timeframe for the interaction? Examples: Lean UX

6 small screen Mouse, Keyboard User Environment Lean UX Control software sewage treatment Context of plant Use IMS-KIS/2011

7 User operates other systems in other rooms simultaneously User Environment Lean UX Control software sewage treatment Context of plant Use IMS-KIS/2011

8 Sometimes User leaves control room to work outside the building User Environment Lean UX Control software sewage treatment Context of plant Use IMS-KIS/2011

9 Chemistry laboratory User Environment Lean UX Control software sewage treatment Context of plant Use IMS-KIS/2011

10 Factory Hall, noisy Touch Screen User Environment Lean UX Control software grinding Context of plant Use UX-Lab/2015

11 Mouse, Keyboard, Large Screen, Internet connection User concentrates on goals of Interaction, quiet environment User Environment Lean UX Context of Library Use

12 Touchscreen, relativ klein, tragbar, Internetverbindung Nutzer in Bewegung, viele Eindrücke aus der Umgebung, laut User Environment Lean UX open Context air museum of Use

13 NFC-Tag auf dem Tisch / smart phone mit kleinem touchscreen Starkes Ablenkungspotential der Umgebung, laut Nutzer in konzentrierter sitzender Haltung User Environment Lean UX pub

14 Navigationsgerät, mittelgroßer touchscreen, Audio sehr gut Aufmerksamkeitsfokus auf Fahrsituation, visuelle und haptische Interaktion nur eingeschränkt möglich User Environment Lean UX Car Context Drivers of Place Use

15 RFID-Chip KP Ludwig Zugangssystem John mit Bildschirm und Sensor Vom Fahrgast mitgeführt: Token oder Chipkarte Kurzzeit Interaktion, mehrfach (Intervall) User Environment Lean UX Context of Metro Use

16 Zwischen den Interaktionen große Pausen, in denen die Aufmerksamkeit anderweitig gefordert ist User Environment Lean UX Context of Metro Use

17 Nach KP Ludwig der Fahrt John Verlassen des Metrosystems durch Rückgabe des Tokens User Environment Lean UX Context of Metro Use

18 RFID KP Ludwig Reader, John Students ID Card, Großer Touchscreen Nutzer steht während der Interaktion, rel. kurze Verweildauer Ablenkung aus dem Umfeld durch Passanten, Beobachter, Geräusche User Environment Lean UX interactive Context public of screen Use

19 How to create Answer the following questions: What s the environment your system will be used in? What s the inner condition of the user while using your app? Discuss and collect 5 minutes Lean UX

23 Elements Categories may be modified depending on the project Name of User Context (There might be more than one) Photograph of User Context Hardware / Interface Beschreibung der genutzten technischen Schnittstellen (Eingabe / Ausgabe) Spatial Situation (calm, busy, viewing distance, surroundings (what happens next to the user)) Personal Situation while interacting (user walks, sits, stands still; concentrated / distracted; physical restrictions) Time Situation while interacting (Duration of Interaction, Interval of Interaction) Lean UX

24 Elements Categories may be modified depending on the project Develop a primary and secondary after the break Name of User Context (There might be more than one) Photograph of User Context Hardware / Interface Beschreibung der genutzten technischen Schnittstellen (Eingabe / Ausgabe) Spatial Situation (calm, busy, viewing distance, surroundings (what happens next to the user)) Personal Situation while interacting (user walks, sits, stands still; concentrated / distracted; physical restrictions) Time Situation while interacting (Duration of Interaction, Interval of Interaction) Have it ready on paper! Stick it on the wall Lean UX

25 Recommendation print it out on paper and pin it clearly visible on the wall of your office therefore: constant reminder, for what situations the project is developed for clear reference of the expected user situation Lean UX

26 Next Hypothesis Writing Lean UX
