The point with the design is not to use modifiers for the keys. You
ether tap the key for main function, or press and drag on different
directions for secondary functions. Making it almost as fast to reach
the secondary function as the main functions.
How many functions per key, and how many keys is factors to experiment
with. Think ether 5x3 (like Your design) or 6x3 is the best number of keys.
The number of function per key reasonable is on of:
tap + drag up, down, left, right. 1+4 = 5 functions.
The hexagon design 1 + 6 = 7 functions.
The first but with added diagonal drag, 1 + 8 = 9 functions.
Higher density and higher number of functions mean less need for
modifiers to reach input functions.
Lower density and fewer functions mean faster and less error prone input
but more need for modifiers. Modifiers are harmful as they have to be
inputted in serial.. not parallel like on a physical keyboard.
Think it takes experimentation to find the optimum.
One possibility is to us 5x3 but have an option to add one more column
that can be used for user defined keys and app specific accelerators.
