onehanded

Onehanded is a term used to describe actions, instruments, or capabilities associated with using a single hand. It can apply to people who rely on one hand due to congenital conditions, injury, or limb loss, as well as to tools and methods designed for one-handed operation. The term is commonly written as one-handed, but the unhyphenated form onehanded is also encountered in some sources.

Applications span daily life, sports, performing arts, and accessibility. In everyday tasks, people may eat, open containers, or manipulate devices with one hand, often aided by deliberate grip choices or adaptive devices. In sports and culture, there are one-handed variations of movements or performances, such as one-handed push-ups, one-handed catches, and one-handed drumming applications, depending on discipline and training.

Technology and accessibility: Many devices are adapted for one-handed use, including one-handed keyboards, specialized computer mice, sip-and-puff and mouth-operated input methods, and switch-access interfaces. Prosthetic and orthotic devices enable one-handed function, using myoelectric, body-powered, or cosmetic options to augment dexterity.

Design considerations: Interfaces and tools intended for one-handed use emphasize reachability, single-handed grip, large targets, and alternative input methods. In product design and ergonomics, one-handed operation is a common criterion for accessibility and usability.
