tweehandenkeyboard

Tweehandenkeyboard is a Dutch term for a keyboard designed to be used with both hands. In ordinary usage it refers to any keyboard layout or device that splits the input area so that each hand operates its own set of keys, as opposed to single-handed input devices. The concept encompasses a range of designs intended to improve comfort, speed, and accuracy by distributing workload between the left and right hands.

Common types include standard two-handed arrangements where the keyboard is divided into left and right halves, and split or ergonomic designs where the halves may be separated, angled, or tented to reduce strain. Such keyboards often feature contoured keywells, adjustable tilt, and sometimes a decoupled or adjustable distance between halves to fit different body postures. Many are highly programmable, allowing users to create layers, macros, and custom key mappings to optimize workflow.

In addition to general two-handed layouts, the term can also apply to specialized input systems that rely on two-handed operation for rapid input. For example, stenography machines used in court reporting employ a chorded two-handed keyboard to input phonetic units, enabling very high speeds, though these devices are distinct from conventional alphanumeric keyboards.

Usage and adoption vary by user and context. Two-handed keyboards are popular in ergonomics discussions and among users seeking reduced finger movement or repetitive-strain relief. They are also common among programmers, writers, and data-entry professionals who benefit from customized layouts and split configurations.
