Complex adaptations, usually only used when aiming for specific niche audiences. Considerations that are only applicable to certain game mechanics, require more budget, specialist knowledge / advice to implement, or don’t benefit as wide a range of people. However they have incredibly high value for the people who do benefit from them.

Motor

(Control / mobility)

• Allow play in both portrait and landscape
• Do not make precise timing essential to gameplay – offer alternatives, actions that can be carried out while paused, or a skip mechanism
• Include a cool-down period (post acceptance delay) of 0.5 seconds between inputs
• Provide very simple control schemes that are compatible with assistive technology devices, such as switch or eye tracking

Cognitive

(Thought / memory / processing information)

• 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

• Allow the font size to be adjusted
• Provide a pingable sonar-style audio map
• Provide pre-recorded voiceovers for all text, including menus and installers
• Provide a voiced GPS
• Allow easy orientation to / movement along compass points
• Ensure that all key actions can be carried out by digital controls (pads / keys / presses), with more complex input (eg. analogue, gesture) not required, and included only as supplementary / alternative input methods
• Ensure screenreader support, including menus & installers
• Use distinct sound / music design for all objects and events
• Simulate binaural recording
• Provide an audio description track

Hearing

• Ensure that subtitles/captions are cut down to and presented at an appropriate words-per-minute for the target age-group
• Provide signing
• Use symbol-based chat (smileys etc)

Speech

• Base speech recognition on hitting a volume threshold (eg. 50%) instead of words
• Use symbol-based chat (smileys etc)

General

• Include every relevant category of impairment (motor, cognitive etc) amongst play-testing participants, in representative numbers based on age / demographic of target audience
• Allow settings to be saved to different profiles, at either game or platform level
• Realtime text <-> speech transcription
