The impact of a well-designed user interface

INTRODUCTION

Servoy World 2011

THE IMPACT OF A USER INTERFACE

• For the user, the user interface is the application

• Question is not only

“What can I accomplish with the software in theory?”

but also

“How good can I accomplish my goals in practice?”

Servoy World 2011

THE IMPACT OF A USER INTERFACE

• Feature tiredness

• What good is a feature that no one ever finds?

• How does the software stand out from the crowd when competitors offer similar features?

• The user interface has the most significant impact on how the software is perceived

Servoy World 2011

THE RELEVANCE OF USER INTERFACE DESIGN

• User Interface Design is about making user interfaces effective, efficient and satisfying to use

• To memorize:

• Effective

• Efficient

• Easy to Learn

• Engaging

• Error Tolerant

Servoy World 2011

THE RELEVANCE OF USER INTERFACE DESIGN

• Disciplines that pave the way for this:

• Usability Engineering

• Visual UI Design

• UI Development

Attributes that make up a great UI

INTUITIVE, SEXY AND CLEAN

Servoy World 2011

INTUITIVE

• Intuition = Understanding without apparent effort(just one of many definitions)

• Intuition is also about making fast decisions without having to compare options

“Don’t make me think”

13INTUITIVE?

14INTUITIVE?

Servoy World 2011

USABILITY ENGINEERING

• Discipline stemming from psychology(e.g. cognitive psychology)

• Solving the right problems(by understanding users’ needs and context)

• Conceptualizing the fundamental information designand interaction design

• Validating that design decisions really work (by evaluating them with real users)

Servoy World 2011

USER-CENTERED DESIGN PROCESS

Think user-centric, involve users

Servoy World 2011

LOW-FI PROTOTYPES (WIREFRAMES & SCRIBBLES) 18

Servoy World 2011

MACRO VS. MICRO-INTERACTION DESIGN

• Macro-Interaction Design

• Defining what is needed where for users to solve their tasks

• Designing the flow and navigation through the application

Servoy World 2011

MACRO VS. MICRO-INTERACTION DESIGN

• Micro-Interaction Design

• Defining how a component behaves in detail(mouse and keystroke level)

• Influences the application’s feel most

Servoy World 2011

VISUAL UI DESIGN

• Enhancing the application’s look

• No visual abstractions anymore – pixel preciseness

• Ideally, visual UI design builds on usability engineering artifacts and “enriches” them

Servoy World 2011

VISUAL UI DESIGN CARES ABOUT…

• Screen (fine) layoutDistances, proportions, dimensions, alignment

• GUI element stylesAffordance, clarity, colors, fonts etc.

• IconsIntuitive, easily recognizable and aesthetic imagery to rapidly communicate application functionality

• AnimationsTransitions between different GUI states that improve orientation

WHAT IS SEXY ANYWAY?

• In this context, it’s definitely not about reproduction

• However, it is about attractiveness and appeal

• Again: intrinsic values can also be sexy

• If we talk of a UI being “sexy” we think of:

Aesthetics and Desirability

Servoy World 2011

IS THIS A SEXY DASHBOARD?

Servoy World 2011

IS THIS A SEXY INVOICING SCREEN?

Servoy World 2011

PUTTING „SEXY“ INTO CONTEXT

• Attractive things work better than unattractive things and are perceived as being „more usable“• Emotions can evoke the “I want to have it” effect

• The look and feel defines how a software is being perceived• Stable

• Professional

• Trustworthy

• etc.

Servoy World 2011

PUTTING „SEXY“ INTO CONTEXT

• Whatever shall be accomplished via visual design: constraints must be considered• Readability

• Support for the color vision impaired

• Standards compliance

• Cultural aspects (BiDi-support, color semantics etc.)

• Technical limitations

Servoy World 2011

CLEAN

• Everything’s in place

• Unnecessary stuff is kept out of sight

• Same things look the same and therefore are familiar

• If we talk of a UI being “clean” we think of:

Information Throughput

THIS IS NOT AN ICON…

BUT THIS ONE IS…

Servoy World 2011

…AND SO ARE THESE

Servoy World 2011

WHY ARE THESE ICONS RECOGNIZABLE AT 16X16 PIXEL?

Servoy World 2011

COHERENT, BUT…

Servoy World 2011

STILL COHERENT, BUT MUCH MORE APPEALING

STYLISTIC DEVICES

• Modern user interfaces require certain stylistic devices

• Alphablending (for shadow and glow effects)

• Textures (for realistic material effects)

• Fluent transitions between different UI states (for better orientation)

• Non-rectangular shaped UI elements

Servoy World 2011

DEFINING STYLES

• Basic colors and fonts should be defined descriptively (just as known from HTML and CSS)

• However, pure descriptive mechanisms (still) have limitations

• Alternative: image-based approaches

Servoy World 2011

MODERN VISUAL EFFECTS

• GUI elements are assembled from simple pixel-graphics

• Advantages• Modern effects can be used (almost) limitlessly

• High rendering performance

• Designers can work with the visual tool that they know best: Photoshop

Servoy World 2011

NORMAL SCALING VS. 9-SLICE-SCALING

• Problem: Pixel-graphics cannot be scaled arbitrarily without suffering from quality issues

Scaling of a buttonwithout 9-Slice-Scaling

Scaling of a buttonwith 9-Slice-Scaling

Servoy World 2011

USING 9-SLICE-SCALING

Servoy World 2011

9-SLICE-SCALING METHOD

• Allows to resize a GUI element without any loss of quality

• This method works in Java Swing and CSS3
