Elastomer tie layer and methods

One variation of tactile interface includes: a flexible substrate configured to deform to a first offset in response to application of a deflecting force on the flexible substrate; a tactile layer defining a tactile surface and configured to deform to a second offset in response to application of the deflecting force on the tactile surface; and a tie layer configured to retain the tactile layer against the substrate, the tie layer defining a first surface contacting the flexible substrate and a second surface contacting the tactile layer, the first surface of the tie layer configured to stretch by the first offset to maintain contact with the substrate and the second surface of the tie layer configured to stretch by the second offset to maintain contact with the tactile layer.
