Double Card Category Memory System

This is an example for a 2-digit card system, encoding 52x52 possibilites for each two cards. To structure these 2704 images in total I created a Category System. It is build on top of a 2-digit Person-Action-Object System (PAO). The PAO then is used to memorize 1.000 people and 1.000 objects, already grouped into 200 categories of 10 each. This so called Millennium PAO can be inspected in another gallery under the following link: http://www.memory-sports.com/millennium-pao/

For this Double Card system I then took my 100 people categories and 100 object categories of 10 images each and expanded it with the missing 704 images. This process was very easy and fitted perfectly into the Millennium PAO images.

If we divide a deck into the four suits, we are left with 13 cards each. Each suit is using index numbers from Ace, 2-10, J, Q and K. If we use the numbers 2-9 as they are, assign Ace to 1 and 10 to 0, we get a sweet row of 0-9. It is very easy now to assign a number based system of ten images each to them, even easier with a category number system.

Each of the 52 cards may face four different suits. That gives us 208 different groups. That is near perfect, because we can fill 200 of these groups already partly with our existing 200 images from the Millennium PAO and assign them to their according number index. Only the Jack, Quenn and King are missing yet and 8 additional entirely new categories.

The most difficult part is then to recognize the correct category by only looking at the index of two cards. I use simple math for that: Each card can bedivided into four suits. Therefore I multiply the index number with a 4, f.e. 7 of any suit = 28. To the result I add the worth of the seconds card suit, which is between 1-4. I use the logic Spades = 1 (because looks like one leave or tree), Hearts = 2 (because the right outer rim looks like a 2 and it has two sides), Clubs = 3 (because it has three bubbles) and Diamond = 4 (because it has four pointy ends). Together that gives me the category number. Only left is the correct image out of the 13 category images.

Finally the last rules are: If it starts with a black card, all images are people. If it starts with a red card, all images are objects. And Clubs and Diamonds add a 50 to the calculation to cover the numbers from 500-999 for each of the people and objects.

All images are shared under fair use for educational purposes and will never be moneytized.
