Dynamic tactile interface
First Claim
1. A dynamic tactile interface comprising:
- a tactile layer defining a peripheral region and a deformable region adjacent the peripheral region;
a substrate coupled to the peripheral region at an attachment surface of the substrate, the substrate defining a back surface opposite the attachment surface, a fluid conduit adjacent the deformable region, a fluid channel fluidly coupled to the fluid conduit, and a via fluidly coupled to the fluid channel and passing through the back surface;
a bladder fluidly coupled to the via and coupled to the back surface of the substrate, the bladder defining a longitudinal axis;
a volume of fluid arranged within the bladder;
a structure adjacent a first side of the bladder;
a platen adjacent a second side of the bladder opposite the first side and compressing the bladder against the structure in a direction substantially perpendicular to the longitudinal axis of the bladder and the platen being translated substantially parallel to the back surface of the substrate to displace fluid from the bladder, through the via, and into the fluid channel to transition the deformable region from a retracted setting into an expanded setting, the deformable region tactilely distinguishable from the peripheral region in the expanded setting; and
a first block coupled to and extending from the back surface of the substrate and a second block coupled to and extending from the back surface of the substrate, the second block laterally offset from the first block;
wherein the bladder suspends between the first block and the second block, an outer surface of the bladder offset from the back surface, a first end of the bladder coupled to the first block, a second end of the bladder opposite the first end of the bladder coupled to the second block, the longitudinal axis of the bladder substantially parallel the back surface.

Abstract
One variation of a dynamic tactile interface includes a tactile layer defining a peripheral region and a deformable region adjacent the peripheral region; a substrate coupled to the peripheral region, a fluid conduit adjacent the deformable region, a fluid channel fluidly coupled to the fluid conduit, and a via fluidly coupled to the fluid channel and passing through the back surface; a bladder fluidly coupled to the via and the substrate; a structure adjacent a first side of the bladder; and a platen adjacent a second side of the bladder opposite the first side and compressing the bladder against the structure substantially perpendicular the longitudinal axis of the bladder and substantially parallel the substrate to displace fluid from the bladder and into the fluid channel to transition the deformable region from a retracted setting into an expanded setting.

10. A dynamic tactile interface comprising:
-
a tactile layer defining a peripheral region and a deformable region adjacent the peripheral region, the deformable region operable between a retracted setting and an expanded setting, the deformable region defining a formation tactilely distinguishable from the peripheral region in the expanded setting; a substrate coupled to the peripheral region at an attachment surface of the substrate, the substrate defining a back surface opposite the attachment surface, a fluid conduit adjacent the deformable region, a fluid channel fluidly coupled to the fluid conduit, and a via fluidly coupled to the fluid channel and passing through the back surface; a sleeve defining a valley of a first cross-section proximal a first end of the sleeve and of a second cross-section proximal a second end of the sleeve, the first cross-section of an area less than an area of the second cross-section, the sleeve operable between a first position and a second position; a bladder fluidly coupled to the via, adjacent the back surface of the substrate, defining a longitudinal axis, and arranged within the valley; a volume of fluid arranged within the bladder; and an actuator coupled to the sleeve and translating the sleeve in a direction substantially parallel to the longitudinal axis from the first position to the second position to displace fluid from the bladder, through the via, and into the fluid channel to transition the deformable region from the retracted setting to the expanded setting, the sleeve proximal a first end of the bladder releasing a portion of the bladder in the first position and proximal a second end of the bladder and constricting the portion of the bladder in the second position. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
