First Claim
1. 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.

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.

4. A haptic feedback device comprising:
-
a display configured to display one or more graphical items, at least one of which has an active state; and

5. 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; and
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.
