Ask HN: A constructed language based on QWERTY swipes?

I had an idea after I got an android phone after a long stint on Apple. The keyboard swipe feature is pretty cool and I like how the swipe texting leaves a vapor trail that slowly fades after you swipe each word. I get the feeling that you might be able to construct a writing system based off of the shapes that are made from swiping words. The distinction between this system of writing and the standard English lettering system is that each character could be represented by a ordinated point in a two-dimensional grid. New characters could be added by extending the two dimensional grid. Further points could be added to the character set in the two dimensional grid. Another unique grid representing other data or data translations could be placed on top of the first and new shapes could be made in the third dimension. I imagine dimensionality is somewhat arbitrary in this example and here use two and three dimensions because they are easy to visualize. What branch of computer science does this fit into? What branch of mathematics could this fit into? Are there any existing natural or constructed languages that use ordinallity as a basis for the identity of their symbols? I am also partly inspired by the animal translation talk that trended here recently. It discussed the similarity of all human natural languages when words were used as the tokens and the differences between words were used to construct a 3d point cloud where differences in ordinallity represented relationships between words. I (perhaps wrongly) surmized that the relationships between the words represent their meaning. I would like to respectfully encourage thoughtful discussion on this topic. Tl;Dr: you can use nlp to make a point cloud where distances convey meaning. What language would you get if you used transforms or datam as points in a point cloud and used shapes to show different sequential combinations of those data?
