Ergodynamics takes into account that everything about standing or walking while typing is different than when users were seated at a desk.
Ergonomic Keyboard Trays
Ergonomic keyboard trays (a.k.a. articulating keyboard trays, or “AKTs”) correct two problems that are caused by placing your keyboard directly on your desk.
The first problem is height—without a keyboard tray, most desktops are too high for strain-free typing. Just about any under-desk keyboard tray will alleviate this issue.
The second problem ergonomic keyboard trays address is tilt. For your wrists to be properly aligned, your keyboard should be able to achieve a negative tilt of around 15° when seated, up to 30° when standing, and potentially more if working at a treadmill desk.
