Introduction

Human interface guidelines (HIG) are software development documents that offer application developers a set of recommendations. Their aim is to improve the experience for users by making application interfaces more consistent and hence more intuitive and learnable.

Structure

Conceptual Model

  • Real World, Vision

Task Flow

  • Core usability goals, Use cases / User requirements, Task aggregation
  • Personas, Scenarios, Usability criteria, Feature list

Organizational Model

Behaviour

Viewing and Navigation

Access functions

Grouping

  • Arrange associated controls by using a labeled group box or an unlabeled frame.
  • Allow users to resize aligned groups by placing a splitter between the groups.
  • Use tabs to show related information on separate pages.
  • Provide an accordion (aka tool box) for different views to content.

Complex views

  • Use a list view to show some items out of one category.
  • Use a tree view to show items with a single, natural, hierarchical categorization.
  • If you really need to create your own widget follow the guidelines for custom controls.
  • Double check the guidelines about plotting diagram/charts.

Editing and Manipulation

Selection

  • Use radio buttons for selection of 1 out of a few items.
  • Use one or more check boxes for clear options or to select items out of a small number of options.
  • Use a drop-down list for selection of 1 out of a small number of items.
  • Use a combo box to select 1 out of a small number of items where users should be able to add items.
  • Use a list view to select 1 singular item out of a potentially big list.
  • Apply the dual list pattern for several selections out of a large number of (multiple) items.

Unconstrained input

  • Provide a line edit to enter one line of text.
  • Provide a text edit to enter multiple lines of texts.
  • Use a table view to arrange data in rows and columns with inline editing feature.

Constrained input

  • Use a spin box for numerical input within a range and with fix steps.
  • Use a slider for arbitrary changes within a defined range.
  • Apply the slider and spin box pattern for numeric input with both large changes and precise control.
  • Use date and time pickers for formatted input of datum, time of day, or periods etc.

User Assistance

User-driven information

  • Provide tool-tips for user driven information.

System triggered notification

Disruptive messages

  • Show a modal message dialog if the processing has reached an unexpected condition that needs interaction.

Help system

  • Support the user by an elaborated interface or per help system.

Presentation

Layout

  • Resizing
  • Default and minimal size
  • Spacing
  • Carefully place control according the KDE alignment style.
  • Do not use color as primary method of communication.
  • icon design

Style

Text
