The joy package contains joy_node, a node that interfaces a generic Linux joystick to ROS. This node publishes a "Joy" message, which contains the current state of each one of the joystick's buttons and axes.
joy ROS joystick drivers for Linux. This package works with Logitech joysticks and PS3 SIXAXIS/DUALSHOCK devices. This package will only build is linux/joystick.h
This package contains the message "Joy", which carries data from the joystick's axes and buttons. It also has the joy_node, which reads from a given joystick port and publishes "Joy" messages.

joy ROS joystick driver for all linux joysticks. The driver will poll a given port until it can read from it, the publish Joy messages of the joystick state. If the port closes, or it reads an error, it will reopen the port. All axes are in the range [-1, 1], and all buttons are 0 (off) or 1 (on).
Since the driver will poll for the joystick port, and automatically reopen the port if it's closed, the joy_node should be "on" whenever possible. It is typically part of the robot's launch file.
The joy_node takes an "~autorepeat_rate" parameter. If the linux kernal receives no events during the autorepeat interval, it will automatically repeat the last value of the joystick. This is an important safety feature, and allows users to recover from a joystick that has timed out.
