Logical Control

An interaction paradigm where the user accesses specific functions supported by an application indirectly, typically by selecting from a presented set of options rather than performing the action directly. Examples include scanning through a menu of commands, using keyboard shortcuts to invoke functions, or selecting items from a list. Logical control contrasts with physical control (direct manipulation) and is generally more suitable for low bandwidth input users because it reduces the number of on-screen positions that need to be reached, lowering the number of signals required. However, it depends on the system correctly predicting or presenting relevant options.
