Keyboard Tilt, Tenting, Orientation
keyboard ergonomics: angles of ergonomic keyboard.
- α is called tilt.
- β is called tenting.
- γ is called orientation.
- 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 are negative tilt, about 20 to 30 degrees.
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 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.
