Agenda

Page 3CIS²E 06: User Interfaces for an In-store Sales Process Supporting System

• e-commerce vs. ‘real world’ shopping

• combine advantages of both

• made-to-measure shirts

• focus on usability

Introduction

Page 4CIS²E 06: User Interfaces for an In-store Sales Process Supporting System

• 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

Page 5CIS²E 06: User Interfaces for an In-store Sales Process Supporting System

• 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

Page 6CIS²E 06: User Interfaces for an In-store Sales Process Supporting System

• Augmented Reality• touch screen

interaction

The Start

Page 7CIS²E 06: User Interfaces for an In-store Sales Process Supporting System

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

• Virtual Reality• knobs and buttons• bar code scanner• touch screen

Moving to VR

Page 9CIS²E 06: User Interfaces for an In-store Sales Process Supporting System

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

• Virtual Reality• custom knob and

buttons device• PDA

Third Iteration

Page 11CIS²E 06: User Interfaces for an In-store Sales Process Supporting System

Usability Test Results

• PDA

– highly useful, except free text entry

– mobility and form factor controversial

• custom knob and buttons devicevery successful

• avatar

– individuality needs improving

– avatar versus product

Page 12CIS²E 06: User Interfaces for an In-store Sales Process Supporting System

• 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
