I was looking at the TECK's website because of our well known troll 'Architect' and I saw how they advertised their keyboard as better for the hand posture because straight boards have people whose hands are straight. However, I recently had an epiphany, well before I saw this post, that one could simply angle their arms differently to produce the exact same effect as a TECK, minus the rise of the keys in the second dimension. I used to type with my arms angled in and wrists straight, as illustrated in the diagram, but I switched to letting my hands fall diagonally onto the keyboard, which I believe is the optimal position for typing and ergonomics.
What brings me the most wrist pain is reaching laterally or diagonally upwards, because the fingers are by nature hinge joints and thus impossible to move laterally without angling the hand. With a 45-degree angle coming onto the board, one can reach diagonally or horizontally with almost no wrist movement, and the hands themselves are in a more comfortable position. I say this as a 130+ typist, who does a lot of writing and type-testing daily. Before, my hands would sometimes deaden in the middle of a minute long test (I'm still a teenager, so I would think that it is probably not age-related), but now my wrists and hands feel very comfortable. Most notably, the keys that the wrist has to move for is lessened. Normally, I reach for (on QWERTY) T, Y, V, B, G, and H, but using the new hand position, with my fingers resting (again in QWERTY terms) on ASDF for the left hand and NKL; on my right- now I reach for T, Y, B, and G. I would say in theory that JIOP would be better for QWERTY typists, as I use Dvorak, but I can't type above seventy on it so I couldn't be sure.
Just a suggestion for those not willing to get an Ergo keyboard but would like their wrists to feel better after typing. And somewhat to laugh at Architect.
