Keyboard Tilt, Tenting, Orientation
keyboard ergonomics: angles of ergonomic keyboard.

- α is called tilt.
- β is called tenting.
- γ is called orientation.
Tilt
- Positive Tilt (tilt up): traditional keyboard has legs at the “back”, that make them positive tilt, about 10 degrees. This causes your wrists to bend up.
- Negative Tilt (tilt down): some ergonomic keyboards have legs in “front” (near the space bar area), called front riser. These create a “negative tilt”, about 20 degrees.

Tenting
Tenting is raising the middle of the keyboard higher. This is good for preventing hand pronation problem. [see Is Keyboard Tenting Important (Wrist Pronation)]
Split 2-pieces ergo keyboards use legs or stand.


Single-piece ergo keyboards may have tenting builtin.



Orientation
Orientation is about how you have to bent you wrist to the left or right. This is most common in single-piece ergo keyboards, having a inverted V shape. Typically 10 to 20 degrees.
