1st person game engine mods

"Blind Monk's Society". Experiments with navigating in darkness, using only audio cues like continuous talking or whistling. A mod using the half-life game engine.

Playing by ear: Documents an experiment using the old Quake engine to create a playable environment for the blind.
One of the most interesting parts I read, was that they used different types of footsteps depending on the location.
"A carpeted study has quiet footsteps, while a kitchen has sharp, echoing footsteps"
This is a common element to add with any platforming/first person game.
It's amazing how much players don't think about the audio. I'm sure the different sounds of footsteps help visual players, even if it's only on a subliminal level.

That blind kid sure plays a mean ... Soul Calibur 2

METRIS!
Musical tetris for the blind! This game is hard. Totally reliant on audio cues, and the unclear instructions didn't help. I got 50 points, which I assume is one line. I found that I would be able to play the game better if I could match the audio cues with visual ones. If there was a version with image and sound, I feel I could match the two spaces, and after learning the audio cues, could advance into the audio only version.
