Embodiment Construction

[0027] FIG. 1 illustrates one embodiment of a system 100 for providing a haptic effect simulating a coefficient of friction at a user interface. A haptic effect refers to a stimulus or force, including but not limited to vibration, attractive or repulsive force, voltage or current, some other mechanical or electromagnetic force, heating or cooling, or some other stimulus. Haptic effects may include one or a combination of forces or stimuli described herein. Various tactile effects can be combined to form an overall tactile effect. Haptic effects can be output at a user interface to provide feedback to a user or object interacting with the interface. It can provide feedback through mechanical movement, such as through the vibration of a solid target, the vibration of a liquid, or actuating an object like a needle or rod to contact the user. A needle or rod deforms a surface by altering its undulations or contours. Overall haptic effects can also provide feedback through elec...

Abstract

A system for generating a haptic effect with an electrostatic device, alone or in combination with actuators or other devices configured to generate a haptic effect. The system may generate the haptic effect to simulate a coefficient of friction or texture on the surface of a user interface, such as a display screen or touchpad. The simulated coefficient of friction may be adjusted to convey other properties on the user interface surface. The system may also include sensors that measure the simulated coefficient of friction and the impedance at the surface.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 13 / 092,269, filed April 22, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to electro-vibration tactile displays. Background technique [0004] Systems are known that provide users with haptic effects in conjunction with visual and / or audio content. It is generally understood that haptic effects can enhance one or more aspects of a user experience associated with content. Previous haptic systems usually only provide stimulation in the form of mechanical vibrations, which limits the interaction between the system and the user. Contents of the invention [0005] According to an aspect of the present invention, an interface device for providing an overall haptic effect is provided. The interface device includes a surface configured to output an overall haptic effect. The inter...
