I use many memorization methods.
This is a small list:
I will provide a description of the methods, plus examples of how to use them.
Visual Memory Methods:
1. Some of the top notch cubist, such as Leyan Lo, use shapes to remember his blindfolded solves. Leyan also orients pieces. What the BLDist does is memorizes a cycle in the shape of a triangle connecting the pieces in the cycle.
2. This is the very basic method that I use, I think it's effective, yet not efficient;
I count as I solve piece by piece. I will alway count consecutively from 1-11.
Some signals I use: "Skip" and "O"
Skip tells me to start a new cycle. "O" (pronounced "oh") designates a piece that is permuted with a twisted orientation.
I do not memorize a string of numbers.
I have 11 variables for edges. (more counting Skips)
These variables are named
"One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven"
As I am counting I am tapping pieces, or at least scanning and remembering the piece that I permute as I count each number.
I remember which piece goes to each variable.
This is similar to Roman Rooms (Which I'll describe later)
PAO (or some breakdown of that)
Person, Action, Objects.
I know that Chris Brownlee uses a PO system
Joel van Noort is working on a PAO system as well.
Each location as a predefined set of images.
With a PAO system (the biggest system), there would be about 72 images. You would then use about 20 of those images to memorize the cube. These 20 or so images would be broken down into 7 key points.
A person (Michael Jordan)
An action (slam dunks)
An object (basketball) This could mean something to somebody with a PAO system.
Let's say that UR->UF->UB gives this story.
UF->UB->UR is the same net effect of the cycle, just memorized from the UF, this would actually result in a completely different blurb.
A person (Chris Hardwick)
An action (solves)
An object (rubik's cube)
Each of the 24 locations have a specific person, action, and object.
You memorize in this order.
You will never get the Action image of the UF if it's a 3n (where n is a whole number) piece in the cycle.
Chris Hardwick and I use letter pairs to memorize big cubes blindfolded. We have a lettering scheme for each piece type. Chris and I don't even use the same lettering scheme, personalize it so that the system makes sense to you, make sure it's something you won't forget.
We have images for every possible combination of 2 letters that can occur, with 24 locations, you get over 500 images! Do not fear the big 500, it is a very powerful system, I'm glad to have learned it and I will probably use it indefinitely for big cubes.
They are very similar mind you.
As memorize the order that pieces are solved we think of the letters associated with the locations, every letter pair is made into an image, then stored in a location, you then progress until all pieces of that type have been solved.
Chris uses a Journey Method, I use Roman Rooms.
What Chris does is he goes to well known locations on a journey. He describes it on his site I believe, take a look at it.
I use Roman Rooms, the way that I use roman rooms, I place one image per location.
I create detailed rooms in my head that I normally am in.
Some of those rooms would include where I work, and the different unique rooms at my house and my grandparents, homes as well.
