Note: this post may or may not help you, I just saw the title and realized I had some experience with it.
So, I was once tapped to run a one-on-one SMS-based RP for a person who wanted to play a blind character (not "blind from birth" but "blinded by circumstance"). Now, I'm a veteran GM...I'd been storytelling for a decade and a half at this point. But I'd never tried to run a game for someone who was playing a character that was blind
. This presents problems for the GM. I mean come on; those of you who have done any roleplaying games know how often a GM prefaces a statement with "you see (X)".
So, I decided to try being blind for an afternoon. To wit, I taped a sleep mask to my face and tried to do basic tasks.
Now, this shit was not fun. Stuff the sighted take for granted - even basic shit like unzipping your fly to take a leak, or finding a chair to sit down in - became quite challenging. But here's what I noticed...
-The first thing you do when your sight is taken from you is try to touch stuff. For one, you want to know where it is...but also, reaching out and touching stuff is something that you can control. But anyway, tactile sensitivity got very acute.
-Air currents are really important when you cannot see. Again, I'm not sure why this is important but when someone opens a door to the outside and you can't see them do it, the sudden movement of air...you really notice it.
-Everything takes a hell of a lot longer when you are blind. As an example, I tried to make a sandwich...that is really hard
when you cannot see. I had to touch and smell everything before I decided to use it...to say nothing of having to actually find the damn refrigerator
before I could even begin the process of feeding myself.
Again though, tactile sensitivity was the second sense to try and take over. Which leads me to my next insight...
-Sounds are scary. When something makes a noise and you cannot identify where it is coming from it bothers the living fuck out of you. When you cannot see you start listening
like you've never listened before...and every noise is suddenly really fucking important
, because you don't actually know where it is coming from. There's this weird thing that happens where you try and "localize" (not sure that's the best word) where the noise you just heard is coming from. After a few hours I was able to discern noises that were close versus noises that were far away. But still, sudden loud noises were not my friends.
Anyhow, these are a few of the things I noticed trying to get by without eyesight for an afternoon. If you are interested in writing a blind character I encourage you to try a similar experiment.
