semiautomatically

Semiautomatically is an adverb describing an action carried out by a system or process with a degree of automation but requiring some human initiation or intervention. The related adjective semiautomatic describes equipment or procedures designed to perform parts of the work automatically while still needing human input for some steps. The term combines semi- (half) with automatic (relying on automatic operation).

In technology and manufacturing, semiautomatic systems perform repetitive tasks with minimal human input but still require operator action at key points, such as loading workpieces, starting a cycle, or handling quality checks. This contrasts with manual systems, where human labor handles most or all steps, and with fully automatic systems, which run without ongoing human control.

In firearms, semiautomatic describes a mechanism that automatically prepares the next round after firing a single shot, so that subsequent shots can be fired with one trigger pull each. The action is automatic only for chambering and ejection, while the trigger remains the individual's control for each shot. In photography or cameras, semiautomatic exposure or focus refers to automatic features with the photographer selecting certain variables, balancing automation with manual choice.

In computing and software testing, semiautomated processes combine automated routines with manual verification or input, such as scripted tests that require inspector approval for results, or semi-automatic data labeling tasks.

Usage tends to emphasize a hybrid approach, signaling efficiency gains from automation while acknowledging the need for human oversight, adjustment, or decision-making in the workflow.
