Abstract
A touch-sensitive touchscreen system may include a touchscreen cover layer, and a tactile structure formed in or coupled to the touchscreen cover layer and defining a non-planar surface texture (e.g., embodied as a ridge or other raised structure or a groove or other depression) that provides tactile feedback to a user's finger. In some embodiments, the tactile structure is formed from at least one material having a different dielectric constant than the touchscreen cover layer. A touchscreen display device arranged under the touchscreen cover may be configured to display a configurable graphical user interface (GUI) including a respective virtual user interface element at a location corresponding with the tactile structure. The system may include a processing unit configured to sense a touch at a location of a particular virtual user interface element, identify the particular virtual user interface element, and initiate an action associated with the virtual user interface element.
