What is mouse interaction? I don’t know about it’s meaning


#5

The OS is constantly tracking the mouse pointer so it always knows where on the coordinate plane it is situated using offsets from the left side for horizontal position, and from the top for vertical position. Just moving the mouse pointer is an event. We can listen for events such as mouse movement, button clicks, scrollwheel movement, etc. and react to those movements with event handlers. This is mouse interaction.
