Abstract

A haptic feedback planar touch control used to provide input to a computer. A touch input device includes a planar touch surface that inputs a position signal to a processor of the computer based on a location of user contact on the touch surface. The computer can position a cursor in a displayed graphical environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user contacting the touch surface. The touch input device can be a touchpad separate from the computer'"'"'s display screen, or can be a touch screen. Output haptic sensations on the touch input device can include pulses, vibrations, and spatial textures. The touch input device can include multiple different regions to control different computer functions.

Claims

1. A haptic feedback device, comprising:

of a user interface device configured to display a graphical object to a user via a touch screen, wherein the graphical object is programmed to have a first state or a second state; and

an actuator coupled to the touch screen and configured to impart a haptic effect to the haptic feedback device when a user'"'"'s input on the touch screen selects the graphical object only when in the first state, wherein the first state is an active state.

2. A haptic feedback device comprising:

a housing;

one or more portions separately movable relative to the housing; and

an actuator configured to impart a first haptic force to one of the separately movable portions and a second haptic force to another of the separately movable portions, or to the housing.

3. A method of scrolling on an electronic device, the method comprising:

selecting a touch screen configured to display a graphical interface having a plurality of graphical objects;

sensing a user'"'"'s input with the touch screen, wherein the user'"'"'s input imparts a scrolling action among the plurality of graphical objects in the graphical interface;

outputting a first haptic effect upon sensing the user'"'"'s input at an edge of a scrolling control region of the touch screen; and

outputting a second haptic effect upon sensing the user'"'"'s input at another location on the scrolling control region.

4. A haptic feedback device comprising:

a housing;

one or more portions separately movable relative to the housing;

a first actuator configured to impart haptic force to one of the separately movable portions; and

a second actuator configured to impart haptic force to another of the separately movable portions, or to the housing.

5. A portable communication device comprising:

a touch screen capable of displaying graphical objects therethrough;

a first actuator configured to impart a first haptic effect to the touch screen at a first frequency; and

a

second actuator configured to impart a second haptic effect to the touch screen at a second frequency simultaneously to provide a third haptic effect to be felt by a user.

6. A method of indicating relative importance in selection of a displayed graphical object, the method comprising:

displaying a plurality of graphical objects through a touch screen, wherein the graphical objects are individually selectable by a user;

sensing the user'"'"'s selection of one or more graphical objects via the touch screen;

outputting a first haptic effect upon sensing a first graphical object is selected by the user, wherein the first graphical object has a first importance value; and

outputting a second haptic effect upon sensing a second graphical object is selected by the user, wherein the second graphical object has a second importance value;

wherein the second haptic effect is greater in magnitude than the first haptic effect.
