Abstract: A haptic response element is contemplated. The haptic response element may generate a tactile feeling as an output and is associated with a computing device. The tactile feeling may be created by moving a part of the haptic response element. A gel may act to return the moving part of the haptic response element to a starting or zero point. Motion of the moving part may exert a shear force on the gel, rather than a compressive force.

Abstract: A touch device including a force sensor disposed between capacitive sensing structures, so both touch and force sensing occur capacitively using device drivers in rows and columns. A dual-layer cover glass, with gel adhesive separating first and second CG layers, so capacitive sensing between the first and second CG layers can determine both touch locations and applied force. The first and second CG layers include a compressible material having a Poisson's ratio of less than approximately 0.48, the force sensor being embedded therein, or disposed between the first and second CG layers. Applied force is detected using capacitive detection of depression of the first CG layer. Depression is responsive to compressible features smaller than optical wavelengths, so those features are substantially invisible to users. Alternatively, the compressible features may be large enough to be seen by a user, but made substantially invisible through the use of a fluid or other element filling spaces between the features. Such a fluid may have an index of refraction equal to, or nearly equal to, the index of refraction of the compressible features.
