The concept of Universally Accessible Games
(UA-Games) has been proposed as a means to
overcome the limitations of previous approaches to
game accessibility, and as an effective technical
approach to achieve game accessibility coupled
with high interaction quality, also putting forward
the objective of creating games that are concurrently
accessible to people with diverse abilities.
UA-Games are interactive computer games that:
- Follow the principles of Design for All, being
proactively designed to optimally fit and dynamically
adapt to different individual gamer characteristics
without the need of further adjustments via
- Can be concurrently played among people with
different abilities, ideally also while sharing the
- May be played on various hardware and software
platforms, and within alternative environments
of use, utilizing the currently available
devices, while appropriately interoperating with
assistive technology add-ons.
All the games can be downloaded from:
- A design method: Unified Design for UA-Games
- The systematic design approach that we have
followed in order to create our UA-Games. This
method reflects a process-oriented discipline
emphasizing abstract task definition with incremental
polymorphic physical specialization.
- A novel concept: Parallel Game Universes
- This theory aims to provide a way for creating
multiplayer games where people with diverse abilities
can play cooperatively, or against each other,
while at the same time experiencing the game in
an optimally adapted way.
- Four games that have a two-fold role, acting
both as proofs of concept and as case studies.
- UA-Chess: a universally accessible
- Access Invaders: a universally accessible
multiplayer and multiplatform version of Space
- Game Over!: the world's first universally inaccessible
game, meant to be used as a game
accessibility educational tool.
- Terrestrial Invaders: a UA-Game packed with
numerous accessibility features that was developed
in order to be able to create Game Overr!!
