  • Intermediate
  • Advanced
  • Full list
  • Why and how

Full list

All three sets of guidelines displayed together as a single categorised list.

Basic

Easy to implement, wide reaching and apply to almost all game mechanics

Intermediate

Require some planning and effort but often just good general game design

Advanced

Complex adaptations for profound impairments and specific niche mechanics

Motor

(Control / mobility)

  • Give a clear indication that interactive elements are interactive
  • Provide an option to turn off / hide background movement
  • Support voice chat as well as text for multiplayer games

  • Highlight important words
  • Include toggle/slider for any haptics

Advanced

  • Provide an option to disable blood and gore
  •  Provide pre-recorded voiceovers for all text, including menus and installers
  • Avoid any sudden unexpected movement or events
  • Allow all narrative and instructions to be replayed
  • Use symbol-based chat (smileys etc)
  • Provide an option to turn off / hide all non interactive elements

Vision

Basic

  • Ensure no essential information is conveyed by a colour alone
  • If the game uses field of view (3D engine only), set an appropriate default for expected viewing environment
  • Avoid VR simulation sickness triggers
  • Use an easily readable default font size
  • Use simple clear text formatting
  • Provide high contrast between text/UI and background
  • Ensure interactive elements / virtual controls are large and well spaced, particularly on small or touch screens

Intermediate

  • If the game uses field of view (3D engine only), allow a means for it to be adjusted
  • Avoid (or provide option to disable) any difference between controller movement and camera movement, such as weapon/walk bobbing or mouse smoothing

Hearing

Basic

  • Provide subtitles for all important speech

About the guidelines

A collaborative effort between a group of studios, specialists and academics, to produce a straightforward developer friendly reference for ways to avoid unnecessarily excluding players, and ensure that games are just as fun for as wide a range of people as possible.
