The core thesis emphasizes that video‑game accessibility must be embedded from the earliest design stages, rather than added later, because retro‑fitting dramatically inflates development time and cost. Drawing on the European EN 301 549 standard and the Ga11y catalogue, the work presents a systematic methodology for evaluating both closed platforms (consoles) and open platforms (PC and mobile) and supplies developers with a practical reference for implementing auditory, visual, motor and cognitive options.

Globally, roughly three billion people play video games, of whom about four hundred million experience some form of disability. Within the Spanish ecosystem, industry bodies such as AEVI and Fundación ONCE have positioned universal accessibility as a strategic priority, encouraging adoption of the outlined standards across the period 2018‑2023, when systematic measures began to emerge after an initial appearance in 2014.

A tiered catalogue of more than thirty accessibility measures is detailed, ranging from basic 1‑star options—identifiable icons, joystick swapping, sound‑mix controls and puzzle‑skip functions—to advanced 5‑star features such as sign‑language interpretation, voice‑to‑text and text‑to‑voice for multiplayer. Each measure is mapped to specific disability profiles (partial or total vision loss, colour‑vision deficiency, hearing loss, motor impairments and cognitive challenges) and is recommended for early integration with configurable settings. A self‑assessment matrix forces developers to verify compliance for every mandatory feature, underscoring that true inclusivity also depends on compatible adaptive peripherals.

The analysis of hardware solutions lists the principal adaptive controllers and accessories available for major consoles, including the Xbox Adaptive Controller, Hori Flex, PlayStation Access Controller, QuadStick, Tobii Eye Tracker 5, the Ford Adapta racing simulator and the OWO haptic jacket, together with their price ranges. It concludes that while commercial peripherals are expanding, gaps remain, making coordinated software‑hardware strategies essential for delivering fully inclusive gameplay across the global market.
