The user currently controlling the mouse and keyboard is called the floor owner . Only
one user (the floor owner) can interact with the desktop at a time. To transition the
floor owner, the current owner must not use the keyboard or mouse for a short
period of time (0.5 seconds). If any other user attempts to use the mouse or
keyboard while the current owner is not using the input devices for this short period
of time, the floor ownership transfers to the new user.
The mouse and keyboard can be disabled for non-primary users. The primary user is
the user that is logged into the desktop of the Sender system. A non-primary user is
a user that is connected, but is not logged in. For example, if UserA is logged into
the Sender system and UserB is connected in, the with I/O disabled, UserB cannot
control the mouse and keyboard.
