Embodiment Construction

[0032] Figure 1A An embodiment of a haptic effect enabled user interface device 100 that can generate a haptic effect on a surface 110 of the device is shown. Haptic effects may be generated to simulate features represented by device 100, such as surface features. For example, a simulated surface feature may be a simulated texture, spatial pattern, edge or boundary, or any other haptic, whether natural or artificial, of surface 110 . The spatial diagram may include a grid of lines, a grid of concentric circles, a grid of points, a grid of tiles, any combination thereof, or any other spatial diagram. In one embodiment, surface 110 may be a touch screen that displays images corresponding to simulated surface features, such as images of spatial map components of a spatial map. In one embodiment, surface 110 may be a touchpad corresponding to a display of images, or any other touch interface.

[0033] Device 100 may include a mobile phone, tablet computer, television, electron...

Abstract

The invention relates to a method and apparatus for providing haptic cues for guidance and alignment with electrostatic friction. A haptic effect enabled device for producing a haptic effect is disclosed. In some cases, the haptic effect may represent a component of a spatial pattern represented on a surface of the haptic effect enabled device. In some cases, the haptic effect enabled device may comprise a haptic output device, a drive module, and a drive circuit. The drive module may receive information indicative of a location of a touch input at the surface and determine whether the touch input's location corresponds with a location of one of multiple components of the spatial pattern. The drive module may generate a drive signal that the drive circuit then applies to the haptic output device to generate the haptic effect.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 728,718, filed November 20, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to methods and devices for simulating surface features on user interfaces using haptic effects. Background technique [0004] Certain electronic user interface devices provide a display screen through which displayed objects may be moved, rotated, or otherwise manipulated. Although a user can move a displayed object to a general area on the screen, moving the object to an exact location on the screen can be difficult. A user moving an object may have difficulty moving the object to an exact location on the display screen because such location is not identified on the screen, or may be obscured by the user's hand. In general, the ability to transmit spatial detail on a user interface screen is lim...
