Haptic feedback for touchpads and other touch controls

A haptic feedback device, comprising:

• a touch input device configured to receive user input and generate an input signal in response to the user input;
• one or more processors configured to receive the input signal, generate a force signal based on the input signal, and generate a graphical environment;
• a display configured to display the graphical environment, wherein the input signal is associated with an interaction by the user with the graphical environment;
• and
• one or more actuators configured to receive the force signal and impart a haptic effect based on the force signal,
• wherein the graphical environment comprises a menu presented at the display, wherein the menu comprises one or more menu items, and wherein the user input comprises navigation between the one or more menu items,
• wherein the one or more menu items comprise a first menu item and a second menu item, wherein the first menu item is associated with a first haptic effect and the second menu item is associated with a second haptic effect different from the first haptic effect.

A haptic feedback device, comprising:

• a touch input device configured to receive user input and generate an input signal in response to the user input;
• one or more processors configured to receive the input signal, generate a force signal based on the input signal, and generate a graphical environment;
• a display configured to display the graphical environment, wherein the input signal is associated with an interaction by the user with the graphical environment;
• and
• one or more actuators configured to receive the force signal and impart a haptic effect based on the force signal,
• wherein the graphical environment comprises a menu presented at the display, wherein the menu comprises one or more menu items, and wherein the user input comprises navigation between the one or more menu items,
• wherein at least one of the one or more menu items is associated with a sub-menu, wherein the actuator is configured to impart the haptic effect when the sub-menu is displayed.

A haptic feedback device, comprising:

• one or more processors configured to receive an input signal and generate a force signal based on the input signal,
• wherein the input signal is associated with a user-independent event,
• the user-independent event comprising one or more of a reminder event, an initiation of a task, a processing of the task, a conclusion of the task, a receipt of an email, or an event occurring in a game;
• and
• one or more actuators configured to receive the force signal and impart a haptic effect based on the force signal.
