One requirement is, that the "thumb area" on both "keyboard gloves" is reserved for trackballs.
Otherwise, the 4 remaining fingers on each "keyboard glove" should be able to deal with or reach 36 keys at minimum but rather ~40 keys
not every row needs the full amount, but a 6 x 7 key grid would be the target
I tried to reach each of the key surfaces with my fingers male medium sized hand (according to https://www.healthline.com/health/average-hand-size#takeaway) and succeeded. Maybe a properly curved and more ergonomic layout could improve this further.
I was drawing a grid with the size for mini choc switches, but instead of 13.5 i did 14 and instead of 14.5 i did 15, so between each key there would be 1mm wiggle room.
The amound of keys is:
6x4 = 24 keys on the bottom
6x6 = 36 keys on the vertical surface
1x6 = 6 on top of the vertical surface
That's a maximum of a total of 66 keys per hand
Given two such gloves for both hands means a possible total of 132 keys which is way more than needed, so it is totally possible to:
either leave out a few keys
or use the larger normal switches instead of the mini ones, because they don't add a lot
or come up with a smart key layout so that someone could actually totally be fine with only a single "keyboard glove" instead of one for each hand
consider further keys using special techniques
e.g. clickable plates row mounted between palm and bended fingers
