Abstract

A system includes an electronic device that includes a display screen, a cover configured to cover the display screen, a sensor configured to sense an input gesture comprising deformation and/or movement of the cover relative to the electronic device, and a processor configured to determine an action for the electronic device to perform based on the input gesture, to determine a haptic effect to generate based on the input gesture and/or the action for the electronic device to perform, and to initiate the action. The system also includes a haptic output device configured to generate the haptic effect.

Claims

an electronic device comprising a display screen;

a cover configured to cover the display screen;

a sensor configured to sense an input gesture comprising at least one of deformation and movement of the cover relative to the electronic device;

a processor configured to determine an action for the electronic device to perform based on the input gesture, to determine a haptic effect to generate to provide information about at least one of the input gesture and the action for the electronic device to perform, and to initiate the action; and

a haptic output device configured to generate the haptic effect,

wherein the haptic output device is embedded in the cover and comprises an electro-rheological or magneto-rheological fluid to control a stiffness of the cover.

2. The system according to claim 1, wherein the sensor is selected from the group consisting of:

a bend sensor, a light sensor, a pressure sensor, a contact sensor, a potentiometer, an angular sensor, an angular velocity sensor, an accelerometer, and a magnetic sensor.

3. The system according to claim 1, wherein the processor is further configured to:

correlate at least one of the deformation and the movement of the cover relative to the electronic device to the input gesture according to a look-up table of predefined input gestures; and

determine the haptic effect to generate based on a library of input gestures and action information and corresponding haptic effects.

4. A method comprising:

sensing an input gesture comprising at least one of deformation and movement of a cover for an electronic device relative to the electronic device with a sensor;

determining an action for the electronic device to perform based on the input gesture with a processor;

determining a haptic effect to generate to provide information about at least one of the input gesture and the action for the electronic device to perform with the processor;

initiating the action for the electronic device to perform with the processor; and

generating the haptic effect with a haptic output device,

wherein the haptic effect comprises at least one of;

resisting peeling of the cover away from the electronic device,

creating a texture when the cover is peeled away from the electronic device,

changing a stiffness of the cover,

actuating at least one hinge located along at least one crease in the cover to fold the cover at the crease, and

restricting movement of the cover to a predetermined angle relative to the electronic device based on the action.

5. The method according to claim 4, wherein the haptic effect is generated during the sensing of the input gesture.

6. The method according to claim 4, wherein the haptic effect is generated after the sensing of the input gesture.
