crosscontrol

Crosscontrol refers to a phenomenon in human-computer interaction and control systems where the input from one control device influences or overrides the input from another. This can occur in various contexts, such as video games, vehicle controls, and industrial machinery. For instance, in a flight simulator, using the joystick might temporarily disable input from the yoke, or in a video game, pressing a specific button might negate the effect of another button press.

The purpose of crosscontrol is often to simplify complex control schemes, prevent conflicting commands, or ensure a logical sequence of operations. It can be implemented to streamline user experience by making certain actions mutually exclusive. However, poorly designed crosscontrol can lead to user frustration and errors, especially if the interactions are not intuitive or clearly communicated. Designers of interfaces that utilize crosscontrol must carefully consider the user's mental model and the intended workflow.

Examples of crosscontrol can be found in automotive systems where pressing the brake pedal may disable the accelerator, or in some software applications where selecting a particular tool changes the functionality of other available tools. The design of crosscontrol mechanisms often involves defining the hierarchy of control inputs and the conditions under which one input takes precedence over another. Effective crosscontrol aims to enhance efficiency and safety by managing the interplay of multiple control sources.
