The model has been created with a broad level of abstraction and sufficient flexibility to allow it to be applied in multiple interactive projects. The options are infinite and it is up to the designers to apply an adequate logic to their purposes.
On the following figures I show more variations of the model using more than one sensor and/or font axis:

I will show you on following posts the possibilities of variable fonts to improve signification from non numeric data as text.
