Ergonomics

When discussing the benefits of ergonomic keyboards, it is important to remember that most regular keyboards are still based on typewriter keyboards (while adding a lot of additional keys!), which were primarily designed to solve mechanical constraints such as preventing jamming.

Unfortunately, scientific studies on keyboards and ergonomics are outdated and lacking. At best, angled keyboards have been considered but almost none of the «modern» features like thumbs usage, minimal keyboards, ortholinear arrangement, alternative layouts, ...

Ergonomics of the ADM42

When designing the ADM42, we decided to create a keyboard where all keys can be reached as easily as possible without having to move hands.

Additionally, the use of thumbs and the symmetry of the keyboard encourages hands alternation and permits to better distribute the load.

Below is a list of what could be considered as ergonomic features:

• One-key distance - The keys are positioned within a maximum distance of one key from the home position, which minimizes fingers and hands movement
• Thumbs usage - Reduces the load on weaker fingers
• Symetric modifiers - Favor hand alternation
• Strong staggering - Especially beneficial for the pinkies
• Ortholinear arrangement - Reduce lateral finger movements
• A flat, angled design with central spacing - A confortable base position without the need for a palmrest
• Better layouts - Colemak-DH and Colemax are included
• Hot-swap switches - Use your favorite switches

We expect that many ot these features will also have a positive impact on typing speed and accuracy.
