work space; working area
Technical term used in computing and engineering contexts to refer to a defined area where work is performed, such as a robot's operational range or a user's workspace in software.
We set up a fence around the robot's working area to secure it.
In this software, you can freely customize the workspace on the screen.
Compound of 作業 (work, operation) and 域 (area, region). A straightforward technical coinage.
