2. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 1 Introduction Methodological Framework Analysis and System Concept Three iterations –Prototype Description –Usability Test Results Conclusions Further Steps Agenda

3. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 2 e-commerce vs. ‘real world’ shopping combine advantages of both made-to-measure shirts focus on usability Introduction

4. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 3 User-Centred Design (UCD) process three major iterations rapid prototypes and system integration demographic profile matching real customers and sales staff quantitative and qualitative testing The User Is King

5. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 4 context of use –customers and sales staff –patterns of activity in sales/shopping behavior basic system concept –in-store, stand-alone, interactive –virtual try-on, e-shop –direct integration into the sales process –SME perspective Analysis and Basic Concept

6. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 5 Augmented Reality touch screen interaction The Start

7. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 6 Usability Test Results symbol card issues selection and ‘try-on’ of shirts to be revised easy shirt composition differences between electronic product catalogue and physical shop fun but not useful extend functionality, better integration, overcome AR drawbacks

8. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 7 Virtual Reality knobs and buttons bar code scanner touch screen Moving to VR

9. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 8 Usability Test Results restrictive range of avatars neutral ratings for overall image quality well-working 3D interaction device successful barcode scanner too complex touch screen interface positive wheelchair user ratings keep concept, simplify customer functionality, enhance presentation quality

10. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 9 Virtual Reality custom knob and buttons device PDA Third Iteration

11. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 10 Usability Test Results PDA –highly useful, except free text entry –mobility and form factor controversial custom knob and buttons device very successful avatar –individuality needs improving –avatar versus product

12. CIS²E 06: User Interfaces for an In-store Sales Process Supporting SystemPage 11 enriched shopping experience intuitive and easy interaction with large information spaces and VR scenes interdependent 3D interaction and business process support controversial attitudes towards highly realistic individual avatars integrate 3D naturally, without technically complex interaction devices Conclusions
