The RAD: Making Racing Games Equivalently Accessible to People Who Are Blind
summary
The RAD is an audio interface that uses standard headphones and a gamepad, implemented on a Unity racing template, to let people who are blind race 3D tracks. It combines a sound slider that computes per-frame trajectories to show edge-danger and lateral position, and a turn indicator system that names turns, plays four beeps (fourth marks turn start) and uses three pitches for sharpness. In a study with 15 participants (3 blind) blind players’ lap times and paths match casual sighted players.
