Interaction design patterns

  1. 1. INTERACTION DESIGN PATTERNS Grau en Enginyeria Informàtica User Centred Design
  2. 2. Introduction • Patterns were architectural concepts that captured recurring design problems in urban architecture. • original definition of a pattern introduced by architect Christopher Alexander. • “Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, allowing the designer to re-use this solution a million times over“ Interaction Design Patterns - User Centred Design 2 / 23
  3. 3. • Patterns (and pattern languages for describing patterns) are ways to describe best practices, explain good designs, and capture experience in a way that it is possible for others to reuse this experience • Design pattern (computer science, object-oriented Design Patterns) are extensively used by software engineers for design process as well as for communicating a design to others Interaction Design Patterns - User Centred Design 3 / 23
  4. 4. Memoria de Largo Plazo (MLP). Long-Term Memory (LTM) • The main thing that the characteristics of long-term memory imply is that people need tools to augment it. • Humankind has a need for technologies that augment memory • software designers should try to provide software that fulfills that need. • designers should avoid developing systems that burden longterm memory • Familiar paths (patterns): • well-learned routes can be done fairly automatically and does not consume attention and short-term memory. • They are stored in LTM Interaction Design Patterns - User Centred Design 4 / 23
  5. 5. Types of Design Patterns • Visual Patterns • In many ways, are the same as patterns in all visual design. Color patterns, the principles and elements of design, and Gestalt theory are all sources of visual patterns, but a few are specific to interactive design • Layout Patterns • Used in the arrangement of content on the page • Common configurations and structures that make a design familiar and navigable for a wide range of users • Architectural Patterns • Deal with the internal information architecture and any interactions that are designed to parse that information Hard relation with Information Architecture • Interaction Patterns • Communicate how an onscreen element can be manipulated to achieve a particular task or to produce a desired result • Conceptual Patterns • Help the user build a mental model of the site and its functionality • Are those that communicate the intended purpose and functionality of an interactive element Difficult to explain: incorporated into all patterns (they may be completely visible …) Interaction Design Patterns - User Centred Design 5 / 23

  7. 7. Interaction Design (ID) PATTERN • An interaction design (ID) pattern is a general repeatable solution to a commonly-occurring usability problem in interface design or interaction design [] • User Interface Design patterns are recurring solutions that solve common design problems. Design patterns are standard reference points for the experienced user interface designer. [] Interaction Design Patterns - User Centred Design Be aware, here problem ≠ error, instead problem = challenge 7 / 23
  8. 8. Interaction Design (ID) PATTERN • Also known as • Interaction patterns • User interface (UI) patterns • Usability patterns • Web design patterns • Workflow patterns • These patterns share a lot of similarities and basically all provide solutions to usability problems in interaction and interface design. • Some patterns are known under different names (or even the same name) in different pattern collections.

  9. 9. • A Pattern capture a common structure without being too concrete on the details which gives the designer flexibility to be creative  it enables to put together something which “feels familiar” while remaining original • But ... Patterns ARE NOT • Off-the-shelf components • Each implementation of a pattern differs a little from every other • Simple rules or heuristics (not a checklist) • A step-by-step description of how to design an interface [Jenifer Tydwell] Interaction Design Patterns - User Centred Design 9 / 23
  10. 10. Requirements (to use UI Patterns) • Field research • System requirements • Goal and Task Analysis • to describe and clarify what users will do with what you’re building • Design models, such as • Personas (models of users) • Scenarios (models of common task situations) • Prototypes (models of the user interface itself) • Empirical testing • Usability testing, in/situ observations, … • Time to iterate over several versions of the design • You won-t get it right the first time !! Interaction Design Patterns - User Centred Design 10 / 23
  11. 11. Usual Elements that describe a UI pattern • Problem/s • Problems are related to the usage of the system and are relevant to the user or any other stakeholder that is interested in usability • Use when • a situation (in terms of the tasks, the users and the context of use) giving rise to a usability problem. • describing situations in which the problems occur • Principle/s • a pattern is usually based on one or more ergonomic principles such as user guidance, or consistency, or error management • Solution/s • a proven solution to the problem • the designer has the freedom to implement it in many ways • Why • a reasonable argument for the specified impact on usability when the pattern is applied • Examples and Implementation details Interaction Design Patterns - User Centred Design 11 / 23

It’s the most comprehensive cross-platform examination of common interface patterns anywhere. ” Dan Saffer 12 / 23

  15. 15. “what users DO” human behaviors patterns, not interface elements • Safe exploration • Let me explore without getting lost or getting into trouble • Instant gratification • I want to accomplish something now, not later • Satisficing • This is good enough. I don’t want to spend more time learning to do it better • Satisfying+sufficing: people accept “good enough” instead “best” if learning the alternatives might cost time or effort • Changes in midstream • I changed my mind about what I was doing • Habituation • That works everywhere else; why doesn’t work here, too? • .....
