  • The following description of the embodiments of the invention is not intended to limit the invention to these embodiments, but rather to enable any person skilled in the art to make and use this invention.
  • 1. First Dynamic Tactile Interface
  • As shown in FIGS. 1A and 1B, a first dynamic tactile interface 100 includes: a substrate 110, a tie layer 120, a tactile layer 130, and a displacement device 140. The substrate 110 defines an attachment surface 116, a support surface 115 continuous with the attachment surface 116, a fluid channel 113, and a fluid conduit 114 configured to communicate fluid from the fluid channel 113 through the support surface 115. The tie layer 120 is deposited onto the attachment surface 116. The tactile layer 130 includes a peripheral region 132 bonded to the tie layer 120, includes a deformable region 131 adjacent the support surface 115 and disconnected from the tie layer 120, and defines a tactile surface 133 opposite the substrate 110. The displacement device 140 is configured to displace fluid into the fluid channel 113 to transition the deformable region 131 from a retracted setting to an expanded setting, wherein the tactile surface 133 at the deformable region 131 is flush with the tactile surface 133 at the peripheral region 132 in the retracted setting (shown in FIG. 1A) and is offset from the surface at the peripheral region 132 in the expanded setting (shown in FIG. 1B).
  • Generally, the first dynamic tactile interface 100 can be incorporated or applied over a display and/or over a computing device, such as a smartphone or a tablet, and define one or more deformable regions of a tactile layer that can be selectively expanded and retracted to intermittently provide tactile guidance to a user interacting with the computing device. In one implementation, the first dynamic tactile interface 100 is integrated into a touchscreen of a mobile computing device, and the first dynamic tactile interface 100 can include a set of round or rectangular deformable regions, each deformable region substantially aligned with a key of a virtual keyboard displayed on the mobile computing device. In this implementation, the deformable regions can thus mimic physical hard keys when in the expanded setting, but when the keyboard is not displayed on the mobile computing device, the deformable regions can retract to yield a uniform, flush tactile layer. In this implementation, the first dynamic tactile interface 100 can also include an elongated deformable region that, in the expanded setting, aligns with a virtual ‘swipe-to-unlock’ input region rendered on the display 180, and the elongated deformable region in the expanded setting can thus provide tactile guidance to a user unlocking the mobile computing device. The elongated deformable region can subsequently transition into the retracted setting to yield a uniform, flush surface over the display 180, such as once the mobile computing device is unlocked and the ‘swipe-to-unlock’ input region is no longer rendered on the display 180.
  • Because the first dynamic tactile interface 100 can be implemented over a display, elements of the first dynamic tactile interface 100, such as the substrate 110, the tie layer layer (e.g., a silicon oxide film), and the tactile layer 130, can be substantially transparent to enable light transmission therethrough. Similarly, features of the first dynamic tactile interface 100, such as the fluid channel 113, the fluid conduit 114, and a drainage hole 117 (described below and shown in FIG. 10D), can be substantially small and/or of suitable geometries to substantially minimize reflection, refraction, and/or diffraction of light output from the display 180 through the first dynamic tactile interface 100, thereby limiting optical distortions perceived by a user (e.g., up to a ‘just noticeable’ difference at a typical viewing distance of twelve inches from the display 180). The substrate 110, the silicon oxide layer, the tactile layer 130, fluid, and/or other components of the first dynamic tactile interface 100 can also be of similar indices of refraction (e.g., at an average wavelength of light in the visible spectrum) or can share similar chromatic dispersion or other optical properties.
  • The substrate 110 of the first dynamic tactile interface 100 defines the fluid channel 113 that is connected to the fluid conduit 114, wherein the fluid conduit 114 is configured to communicate fluid from the fluid channel 113 through the attachment surface 116. The substrate 110 can be substantially planar and substantially rigid and therefore can retain the peripheral region 132 of the tactile layer 130 in substantially planar form in and between the expanded and retracted settings. However, the substrate 110 can be of any other form, such as curvilinear, convex, or concave, and the substrate 110 can also be flexible.
  • The substrate 110 can be of acrylic (Poly(methyl methacrylate) or PMMA) such that the substrate 110 is substantially translucent. However, the substrate 110 can alternatively be surface-treated or chemically-altered PMMA, glass, chemically-strengthened alkali-aluminosilicate glass, polycarbonate, acrylic, polyvinyl chloride (PVC), glycol-modified polyethylene terephthalate (PETG), polyurethane, a silicone-based elastomer, or any other suitable translucent or transparent material or combination thereof. Alternatively, the substrate 110 can be opaque, such as for arrangement over an off-screen region of a mobile computing device. The substrate 110 can also be of various different materials. For example, the substrate 110 can include a glass base sublayer bonded to a fluid channel and fluid conduit formed of PMMA. The substrate 110 can also be of a material exhibiting adequate adhesion properties with tie layer (e.g., a silicon oxide film) such that the tie layer 120 deposited onto the attachment surface 116 can function to retain the peripheral region 132 of the tactile layer 130 against the substrate 110 despite the position of the deformable region 131 or the fluid pressure between the substrate 110 and the deformable region 131. For example, adhesion the tie layer and the substrate and between the tie layer and the tactile layer can be enhanced with surface treatments, such as described below. The tie layer can also include a multiple layers and/or include a thin metallic layer a few angstroms thick.
  • The fluid channel 113 can be a blind channel defined within the substrate 110. In one variation of the first dynamic tactile interface 100 shown in FIGS. 1A and 1B, the substrate 110 includes a first sublayer 111 and a second sublayer 112 that, when joined, cooperate to define and to enclose the fluid channel 113. The first sublayer 111 can define the attachment surface 116, and the fluid conduit 114 can pass through the first sublayer 111 to the attachment surface 116. In this variation, the first and second sublayers, can be of the same or similar materials, such as PMMA for both sublayers or surface-treated PMMA for the first sublayer 111 and standard PMMA for the second sublayer 112.
  • The fluid channel 113 can be one of a set of fluid channels that communicate fluid to one or more fluid conduits of the deformable region 131. Fluid channels in the set of fluids channels can also intersect, such as in the vicinity of the deformable region 131. Implementation of multiple channels feeding fluid to the deformable region 131 can increase flow rate to or from the deformable region 131, thus yielding faster transitions between retracted and expanded settings. This can additionally or alternatively enable implementation of fluid channels of smaller cross-sectional areas, which may be less visible to a user. Multiple fluid channels can be incorporated into a system configured to independently expand one or more deformable regions simultaneously.
  • As shown in FIG. 9A, the fluid channel 113 can be created by forming (or cutting, stamping, casting, etc.) an open channel in the first sublayer 111 of the substrate 110 and then enclosing the channel with a second sublayer 112 (without a channel feature) to form the enclosed fluid channel and the substrate 110. Alternatively, as shown in FIGS. 9A and 9B, the substrate can include two sublayers, including a first sublayer 111 defining an upper open channel section and including a second sublayer 112 defining a lower open channel that cooperates with the upper open channel to define the fluid channel 113 when the first and second sublayers 111,112 are aligned and joined. For example, each sublayer can include a semi-circular open channel, wherein, when bonded together, the sublayers form an enclosed fluid channel with a circular cross-section, as shown in FIG. 9C. Because small cross-sections may affect fluid flow rate through the fluid channel 113, this fluid channel geometry may enable higher flow rates than other cross-sections. However, the substrate 110 can define a fluid channel of any suitable cross-section, such as square, rectangular, circular, semi-circular, ovular, etc.
  • In one example implementation, the fluid channel 113 and the fluid conduit 114 are cut into the first sublayer 111 opposite the attachment surface 116 via conventional machining. The first and second sublayers, can then be treated and surface activated in ultraviolet ozone for a specified period of time (e.g., several minutes), as shown in FIG. 8A. The first and second sublayers, can then be stacked in alignment on a compression fixture (shown in FIG. 8B) and compressed according to a time, temperature, and pressure schedule (shown in FIG. 8C), such as one hour at 300 psi of compression at a temperature of 50° C. The stack can also be compressed according to an environment schedule throughout a portion or all of the compression cycle, such as an environment that is dry argon, wet hydrogen (i.e., hydrogen mixed with small quantities of air or water), or vacuum (e.g., 10̂-6 Torr). The stack can additionally or alternatively be laminated in a compression machine (e.g., with rollers) that bonds the layers of the stack by applying pressure and/or heat across portions of the stack over time.
  • The first dynamic tactile interface 100 can also include multiple substrates, each defining one or more fluid channels and vias, such as shown and described in U.S. patent application Ser. No. 12/652,704, filed on 5 Jan. 2010, which is incorporated in its entirety by this reference. In this implementation, substrates can be stacked with vias in alignment to enable communication of fluid across multiple substrate layers, and the stack of substrates can then be bonded according to any of the foregoing or forthcoming methods or techniques.
  • The compression fixture implemented in the foregoing example implementation can be a two-part fixture including a cope side and a drag side. Each of the cope and drag sides can include a bonding surface and a support surface that supports the bonding surface via one or more flexures, as shown in FIG. 8. In this example implementation, the sheet materials that define the substrate 110 and the tactile layer 130 can extend beyond the compression portions of the compression fixture (e.g., beyond the flexure), which can reduce distortion of the substrate 110 and tactile layer proximal the boundary of the compression portions of the compression fixture. Furthermore, alignment features integral with the sheet materials that define the substrate 110 and the tactile layer 130 can be arranged beyond the portions of the materials within the compression portions of the compression fixture. Each side of the compression fixture also can include a recess with geometry, form, and width correlating with and/or substantially similar to that of the fluid channel 113 such the stack can be set between the cope and drag plates and compressed without collapsing the fluid channel 113. The cope and/or drag plates can also include locating features that align the stack with the recess. Furthermore, the drag side can include at least one male locating feature, and the cope side can include at least one female locating feature such that the halves of the compression fixture can be repeatably aligned.
  • In the foregoing example implementation, the first sublayer of the substrate 110 can include an open valley opposite the attachment surface 116, wherein the open valley substantially defines the fluid channel 113 when the first and second sublayers are joined. The first sublayer 111 also can include at least one through-bore that passes from a portion of the fluid channel 113 to the attachment surface 116 such that the fluid channel 113 and fluid conduit can be formed in the first sublayer 111 substantially simultaneously and/or in the same manufacturing setup. However, in this or other manufacturing implementations, the fluid channel 113 and/or fluid conduit can be created in the substrate 110 (e.g., in the second sublayer 112 and/or in the first sublayer 111) via any suitable manufacturing technique, such as by etching, drilling, punching, stamping, molding, casting, etching, bulk micromachining, or any other suitable manufacturing process. Furthermore, the first and second sublayers, can be cleaned, treated, and/or activated via any other process, or combination of processes, such as via low-temperature heating in a vacuum, via etching, or via a solvent wipe. The stack can also be compressed according to any other time, temperature, pressure, and/or environment schedule. Following assembly, the stack can be further post-annealed, such as by heating the stack according to a particular time, temperature, and/or environment schedule to modify the crystalline (e.g., grain) structure with the layers of the stack.
  • Therefore, as shown in FIG. 7, a first method S100 for enclosing a fluid channel 113 within a substrate 110 includes: cleaning a first translucent sublayer of the substrate 110 that defines a fluid conduit 114 through a broad face of the first sublayer 111 as shown in FIG. 8A as Block S110; cleaning a second sublayer 112 of the substrate 110 as shown in FIG. 8B as Block S120; aligning the first and second sublayers 111, 112 in a compression fixture, wherein the first and second sublayers 111, 112 form a stack and cooperate to enclose the fluid channel 113 that aligns with the fluid conduit 114 as shown in FIG. 8C as Block S130; and compressing the stack according to a time, temperature, and pressure schedule as shown in FIG. 8D as Block S140.
  • The first method S100 can be implemented to join the first and second sublayers 111, 112 of the substrate 110 of the first dynamic tactile interface 100, as described above. The first method S100 can therefore also include curing the sublayer stack according to a time, temperature, pressure, and environment schedule. However, the first method S100 can include any other procedure implemented in any other way to enclose the fluid channel 113 within the substrate 110.
  • As shown in FIGS. 1 and 4, the substrate 110 can further define a support surface 115 adjacent the deformable region 131, wherein the support surface 115 defines a hard stop for the tactile layer 130 that resists inward deformation of the deformable region 131 due to an input on the tactile surface 133. The support surface 115 can further be in-plane with the attachment surface 116 proximal the peripheral region 132 such that the support surface 115 resists inward deformation of the deformable region 131 past the plane of the peripheral region 132, though the support surface 115 can be of any other geometry or form. The fluid conduit 114 can pass through the support surface 115 such that the fluid conduit 114 can communicate fluid from the fluid channel 113 to the interior surface of the tactile layer 130 to transition the deformable region 131 between settings.
  • The fluid channel 113 can be defined as an elongated recess of constant cross-section and depth through the substrate 110. The cross-section of the fluid channel 113 can be rectilinear, though the cross-section of the fluid channel 113 can alternatively be circular, semi-circular, curvilinear, ovular, triangular, trapezoidal, elliptical, or any other suitable cross-section. The fluid channel 113 also can include a series of orthogonal linear segments that meet at arcuate or filleted sections (shown in FIG. 3) to form a serpentine path configured to communicate fluid to a plurality of adjacent deformable regions separated by peripheral regions. The substrate 110 can also define the fluid channel 113 that is of varying cross section along its length, such as varying width, constant-width with oscillating profile along the length of the fluid channel 113, or a sinusoidal, waveform, or ‘squiggle’ oscillating profile. The cross-section (e.g., geometry, height, width, etc.) of the fluid channel 113 (and/or fluid conduit) can be tailored for particular speed and/or pressure of fluid flow at one or more particular regions along the length of the fluid channel 113. Furthermore, the substrate 110 can also define the fluid channel 113 that is an open channel or a sunk (e.g., buried) channel, or the substrate 110 can define the fluid channel 113 in any other suitable way. However, the fluid channel 113 can be of any other constant or varying depth, any other constant or varying cross-section, linear or non-linear path, linear or non-linear profile, or of any other geometry, profile, form, or path.
  • The fluid conduit 114 can be circular in cross-section and normal to the attachment surface 116 or of any other profile and/or cross-section. The fluid conduit 114 can also be one in a set of fluid conduits paired with the deformable region 131, wherein the set of fluid conduits cooperate to direct fluid between the fluid channel 113 and the interior surface of the tactile layer 130. Furthermore, the cross-sectional area of the fluid conduit 114 at the attachment surface 116 can be less than the cross-sectional area of the fluid channel 113 at the junction with the fluid conduit 114, such as shown in FIGS. 11A and 11B. However, the fluid conduit 114 can be of any other form, geometry, or profile.
  • The substrate 110 can further define one or more drainage holes 117 fluidly coupled to the fluid conduit 114 and to the fluid channel 113. The drainage holes 117 can be in fluid communication with the back surface of the deformable region 131 and adjacent the fluid conduit 114. For example, the fluid conduit 114 can define an outlet substantially proximal the center of the deformable region 131 and the drainage hole 117 can define a fluid inlet substantially proximal and within the boundary of the deformable region 131, and the outlet of the drainage hole 117 can be coupled to the fluid channel 113 to communicate fluid back into the fluid channel 113. Furthermore, the cross-section of the drainage holes 117 can be substantially smaller than the cross-section of the fluid conduit 114 such that the fluid conduit 114 defines a primary fluid path to communicate fluid toward and away from the back surface of the deformable region 131. The drainage hole 117 can thus function to permit additional fluid, trapped under the deformable button during a transition to the retracted setting, to passively escape a fluid cavity between the substrate 110 and the back surface of the deformable region 131. This can enable more complete drainage of fluid from the cavity and thus a more predictable and/or consistent form of the deformable region 131 in the retracted setting. Generally, the fluid can be actively pumped into and/or out of the fluid cavity via the fluid conduit 114 to transition the deformable region 131 between expanded and retracted settings, and fluid can passively move out of the cavity via the drainage holes 117 to improve efficacy of transitions into the retracted setting. However, the drainage hole 117 can additionally or alternatively be coupled to a drainage source that actively draws fluid out of the fluid cavity to actively retract the deformable region 131, though the drainage hole 117 can function in any other suitable way.
  • As shown in FIGS. 10A-10C, the attachment surface 116 can also define one or more grooves 119 that provide additional paths for fluid to flow into or out of the fluid conduit 114 and/or drainage holes 117 during a transition between the retracted and expanded settings. Like the drainage hole 117, grooves 119 can assist removal of fluid from the fluid cavity and thus prevent fluid from being trapped between the tactile layer 130 and the substrate 110. The grooves 119 can be shallow, deep, narrow, wide, or of any other constant or varying cross-section or geometry and can also feature microtexturing or other suitable surface treatment or profile. The grooves 119 can extend only over the portion of the substrate 110 adjacent the deformable region 131 (shown in FIGS. 10A and 10B) or into the peripheral region 132 (shown in FIG. 10C). The substrate 110 can define multiple grooves, such as grooves that intersect across the portion of the substrate 110 adjacent the deformable region 131 of the tactile layer 130, such as in a checkerboard pattern (shown in FIGS. 10A and 10C), a pattern of radiating lines and concentric circles (shown in FIG. 10B), or randomly arranged linear or nonlinear grooves. The back surface of the tactile layer 130 can also define ridges that align with and substantially dip into or fill the groove(s) in the retracted setting. Alternatively, the back surface of the tactile layer 130 can define one or more grooves, and the attachment surface 116 can also define one or more ridges that align with and fill one or more grooves in the tactile layer 130 in the retracted setting.
  • The form, profile, surface finish, and/or geometry of the fluid conduit 114 and the fluid channel 113 can be selected to limit optical distortion of an image transmitted through the substrate 110, such as scattering, diffraction, refraction, or reflection. These variables can also be tailored to inhibit unwanted back-reflection of impinging light, such as from an external light source or the sun. Furthermore, these variables can also be tailored to limit directional or preferential light scattering in a particular direction in favor of even distribution of light scattering or refraction through the substrate 110 and the tactile layer 130. The fluid channel 113 and fluid conduit can further include concave or convex fillets of constant or varying radii at any edge, corner, or apex such that unwanted optical distortion, such as scattering, reflection, refraction, and/or diffraction, can be minimized at such features. Additionally or alternatively, the fluid channel 113 and/or fluid conduit can be of a substantially small cross-sectional area that reduces light scattering at a fluid-substrate boundary or interface. The fluid channel 113, fluid conduit, and tactile layer can also be substantially clean before the first dynamic tactile interface 100 is filled with fluid in order to promote wetting and/or to minimize nucleation sites (e.g., for bubbles) throughout the fluid path(s) within the first dynamic tactile interface 100. Air can also be evacuated from the fluid channel 113, fluid conduit, and tactile layer can also be prior to filling the first dynamic tactile interface 100 with fluid. The fluid channel 113 and/or fluid conduit can also be hydrophobic or hydrophilic. The geometry and/or the minimal cross-sectional area of the fluid conduit 114 and the fluid channel 113 can render the fluid conduit 114 and the fluid channel 113 substantially optically imperceptible to a user. The geometry and/or the minimal cross-sectional area of the fluid conduit 114 and the fluid channel 113 can also limit optical distortion through the substrate 110 to less than a just noticeable difference, such as at a typical working distance of twelve inches between the tactile surface 133 and an eye of a user. Generally, the geometry and/or minimal cross-sectional area of the fluid paths can yield the benefit of limiting optical abnormalities of the first dynamic tactile interface 100 below a just noticeable difference.
  • The tie layer 120 of the first dynamic tactile interface 100 is deposited on the attachment surface 116. The tie layer 120 can function as an activatable adherent that chemically and/or mechanically bonds the substrate 110 to the tactile layer 130. For example, the tie layer 120 can include a silicone oxide film applied to the attachment surface 116 of the substrate 110 via a chemical vapor deposition process, as shown in FIG. 6A. Alternatively, the tie layer 120 can be applied via sputtering, plasma polymerization, mechanical application via a rolling drum, or any other suitable process that yields a silicon oxide film of substantially even thickness across the attachment surface 116. The thickness of the tie layer 120 can be sufficiently thin such that a person interacting with the dynamic tactile interface 100 finds difficulty in distinguishing the tie layer 120 by sight and/or by feel. For example, the tie layer 120 can be less than one micrometer (1 μm) in thickness.
  • The tie layer 120 can be selectively applied to the attachment surface 116. In one example implementation, prior to application of the film, a weighted (or magnetized) shield is placed over the portion of the attachment surface 116, the shield covering a particular area that will be adjacent to the deformable region 131, wherein the shield prevents deposition of silicon oxide over the substrate 110 at the particular area. In another example implementation, prior to application of the film, a sticker-type mask is selectively adhered to the attachment surface 116, specifically at portions that will be aligned with deformable regions of the tactile layer 130. Alternatively, the tie layer 120 can be applied across the attachment surface 116 and subsequently selectively removed, such as through laser ablation or plasma etching. However, the tie layer 120 can be (selectively) applied in any other way, can be of any other thickness, and can also or alternatively be applied to the interior surface of the tactile layer 130.
  • In other variations of the first dynamic tactile interface 100, a different material, such as urethane, polyurethane, epoxy, silicone, titanium, gold, primer, adhesives, an adhesive monomer layer, or any other suitable material or combination of materials enabling adhesion between the tactile layer 130 and the substrate 110, is used in place of silicon oxide to create the film that joins the tactile layer 130 and the substrate 110. In yet other variations of the first dynamic tactile interface 100, the silicone oxide layer is excluded entirely and the substrate 110 is bonded or coupled directly to the tactile layer 130.
  • The tactile layer 130 of the first dynamic tactile interface 100 defines the peripheral region 132 that is bonded to the tie layer 120 and the deformable region 131 that is adjacent the deformable region 131, adjacent the fluid conduit 114, and disconnected from the tie layer 120. The tactile layer 130 also defines the tactile surface 133 opposite the substrate 110. The tactile layer 130 can be of a flexible and/or elastic material that is translucent or transparent, such as polyethylene terephthalate (PET), polycarbonate (PC), silicone, or urethane. However, the tactile layer 130 can be any other substantially transparent material.
  • As shown in FIG. 1A, the tactile layer 130 can include two sublayers, including an outer sublayer and a buffer backing. The outer sublayer can be substantially rigid and durable to resist scratching and can be bonded to the tie layer 120 via the buffer backing. In one example, the outer sublayer is a more rigid material such as polycarbonate or PET (polyethylene terephthalate), and the buffer backing is substantially more extensible, has a lower modulus, and is more elastic, such as silicone. The tactile layer 130 is operable between the expanded and retracted settings, wherein the outer sublayer deforms between settings and the buffer backing substantially absorbs deformation of the tactile layer 130 proximal a deformation boundary around the deformable region 131. Because the outer sublayer can be a substantially transparent polymer, repeated transitions between the expanded and retracted settings can result in crazing or drawing near the deformation boundary, which can reduce optical clarity near the circumference of the deformable region 131 and/or result in plastic deformation of the tactile layer 130 over time. However, the buffer backing can soften or cushion the transition region of the outer sublayer at the border between the deformable and deformable regions. Generally, the buffer backing can stretch in a direction of deformation (e.g., outward) when the tactile layer 130 is expanded to absorb sharp deformation of the outer sublayer between settings. Therefore, the tactile layer 130 that includes an outer sublayer and a buffer backing can exhibit improved scratch-resistance and a glass-like tactile feel at the tactile surface 133 while maintaining optical clarity at deformation boundaries throughout repeated transitions between expanded and retracted settings. The tactile layer 130 that includes multiple (e.g., two) sublayers can also enable strain due to application of force on the tactile layer 130 to preferentially manifest in the softer (i.e. buffer) sublayer and rather than the harder (outer) sublayer, which can permit less extensible, more durable layers to be used as the outer sublayer of the tactile layer 130.
  • The tactile layer 130 can be of uniform composition across the deformable and peripheral regions. However, the tactile layer 130 can be selectively flexible or elastic. For example, materials arranged at the deformable region 131 can be substantially flexible or elastic and materials arranged at the peripheral region 132 can be substantially less flexible or less elastic. The tactile layer 130 can also be of uniform thickness, such as less than one millimeter (1 mm) across the deformable and peripheral regions. However, the tactile layer 130 can alternatively be of non-uniform thickness. For example, the tactile layer 130 can be thinner at the deformable region 131 than at the peripheral region 132 to increase flexibility at the deformable region 131. In another example, the tactile layer 130 can be thicker at the deformable region 131 than at the peripheral region 132 such that the tactile surface 133 of deformable region defines a lip or edge on the tactile surface 133. In a further example, the tactile layer 130 can be thicker at the deformable region 131 than at the peripheral region 132 such that the deformable region 131 extends into a recess on the interior surface of the substrate 110 adjacent the fluid conduit 114, wherein the recess includes the support surface 115 that supports the extension of the deformable region 131 to prevent inward deformation of the deformable region 131 in the retracted setting due to an input on the tactile surface 133. In still another example, the interior surface of the tactile layer 130 can include a valley that at least partially defines the fluid channel 113 when the tactile layer 130 is bonded to the substrate 110. However, the tactile layer 130 can be of any other form or geometry.
  • The tactile surface 133 of the tactile layer 130 can be substantially smooth to the touch. Alternatively, the tactile surface 133 can include a matte, textured, or patterned surface. For example, a matte surface may reduce glare from reflected light and yield beneficial light transmission and light scattering properties at the tactile surface 133. A matte finish can also be applied on top of the tactile surface 133, such as before the tactile layer 130 is bonded to the substrate 110 or before sublayers of the tactile layer 130 are joined. A matte finish or texture can also be applied to the tactile surface 133 during a bonding process to join the tactile layer 130 to the substrate 110 or to join sublayers of the tactile layer 130. For example, a heated matte-patterned roller can be passed over the tactile surface 133 or a smooth heated roller can press a matte-patterned sheet over the tactile layer 130, either of which can impress a matte pattern into the tactile surface 133. However, other patterns or surface features can be additionally or alternatively applied to the tactile surface 133, another sublayer or surface of the tactile layer 130, other surface or sublayer of the substrate 110, etc. Furthermore, a pattern or finish can be applied to any one or more layers, sublayers, or surfaces of the first dynamic tactile interface 100 in any other suitable way.
  • The tactile layer 130 can be bonded to the substrate 110 via the tie layer 120, which can retain the tactile layer 130 to the substrate 110 via a mechanical bond by enabling crystalline grain growth across a boundary between the tie layer 120 and the adjacent interior surface of the tactile layer 130. Alternatively, the tie layer 120 can retain the tactile layer 130 against the substrate 110 via covalent bonds, wherein the tie layer 120 bonds covalently with the tactile layer 130 while being retained by the underlying substrate. However, the tie layer 120 can retain the tactile layer 130 to the substrate 110 via entanglement of polymer strands between layers, hydrogen bonds, Van der Walls bonds, or any other suitable type of chemical or mechanical bond or attachment.
  • In one variation of the first dynamic tactile interface 100, the tie layer 120, previously deposited on the attachment surface 116 (shown in FIG. 6A), is pre-treated with a corona treatment (e.g., air plasma treatment). The corona treatment can improve the surface energy and create reactive species of the tie layer 120 in preparation for bonding with the tactile layer 130. The interior surface of the tactile layer 130 can be masked at the deformable region 131, as shown in FIG. 6B, and then pre-treated with a corona treatment and/or cleaned in ultraviolet ozone, as shown in FIG. 6C. At least one of these processes can prepare the interior surface of the tactile layer 130 for bonding at exposed areas only, which can include the peripheral region 132 and exclude the deformable region 131 such that the deformable region 131 remains disconnected from the substrate 110 via the tie layer 120. The tactile layer 130 and the tie layer 120 can then be stacked, aligned, and laminated. The stack can be laminated by passing the stack through a set of rollers, as shown in FIG. 6D and then cured according to a time, temperature, pressure, and environment schedule, as shown in FIG. 6E, such as at 30 psi for two hours at room temperature in a dry nitrogen environment. The stack can then be trimmed to size.
  • The curing schedule can define application of temperature and pressure the tactile layer 130 and silicone oxide film over time to yield a substantially adequate bond therebetween. The curing schedule can also improve the bond between the substrate 110 and the tie layer 120. The bond between the tie layer 120 and the substrate 110 and/or the tactile layer 130 can be a macroscopic mechanical bond, such as a diffusion bond defined by cross-boundary grain growth such that the tie layer 120 and at least one of the substrate 110 and the tactile layer 130 appear as a singular structure substantially proximal a boundary. Additionally or alternatively, the bond between the tie layer 120 and the substrate 110 and/or the tactile layer 130 can be a chemical bond. For example, atoms or molecules on a first side of a boundary combine with atoms or molecules on a second side of the boundary to form a third material proximal the boundary. The third material can exhibit adequate adhesion to the parent materials on each side of the boundary, as well as adequate cohesion between molecules within the third material to retain the peripheral region 132 of the tactile layer 130 to the attachment surface 116 of the substrate 110. Furthermore, the curing schedule can include curing in an inert environment, such as nitrogen or argon, to minimize contamination of the bond, which can negatively affect the strength of the bond and/or the optical clarity of the substrate 110 and tactile layer stack. However, the bond between the tie layer 120 and at least one of the substrate 110 and the tactile layer 130 can be any other type of bond or combination of types of bonds and can be achieved in any other way.
  • In the foregoing variation of the first dynamic tactile interface 100, the tie layer 120 can also or alternatively be selectively pre-treated to ensure joining at the peripheral region 132 and not at the deformable region 131, such by applying a mask or shield over select portions of the tie layer 120 prior to treatment. The tie layer 120 can also be treated via other techniques, such as ultraviolet ozone treatment, low-pressure plasma, corona discharge, etching, flame treatment, or solvent wipe. Any of these treatments can additionally or alternatively be applied to the interior surface of the tactile layer 130 prior to lamination to ensure select adherence between the tactile layer 130 and the substrate 110 via the tie layer 120. Similarly, an anti-stick or bond-inhibitor coating can be applied to areas of the back surface of the tactile layer 130 and/or to the tie layer 120 in areas corresponding to the deformable region 131. Furthermore, the tactile layer 130 can be selectively bonded to the tie layer 120 via “masked” or selective irradiation or heating during a bonding or laminating process.
  • The tactile layer 130 and substrate can include alignment features, such as print markers (e.g., “+” or “−” marks) at two or more corners of each of the tactile layer 130 and the substrate 110 to aid manual alignment or automated alignment via machine vision. Alternatively, the substrate 110 and the tactile layer 130 can be supplied as sheets in separate rolls that are merged as they enter a set of laminator rollers. The set of rollers can be a pair or rollers into which the substrate 110 and tactile layer stack is fed, or the substrate 110 and tactile layer stack can be laminated between a static flat plate and a single roller or laminated between two faces in a press. One or more rollers or press faces can be heated, such as with an induction heating coil or with a quartz heating rod, to boost bond temperature, which can increase bond strength, improve optical clarity, and/or reduce cure time for the stack.
  • Therefore, as shown in FIG. 5, a second method S200 for bonding a tactile layer 130 to a substrate 110 can include: depositing a tie layer 120 onto an outer broad face of the substrate 110 as shown in FIG. 6A as Block S210; masking an inner broad face of the tactile layer 130 at a deformable region 131 as shown in FIG. 6B as Block S230; activating the inner broad face of the tactile layer 130 at an peripheral region 132 as shown in FIG. 6C as Block S212; laminating the inner broad face of the tactile layer 130 to the outer broad face of the substrate 110 to form a tactile layer 130 and substrate 110 stack as shown in FIG. 6D as Block S250; and curing the tactile layer 130 and substrate 110 stack under pressure as shown in FIG. 6E as Block S240.
  • The second method S200 can be implemented to bond the tactile layer 130 and the substrate 110 of the user interface 100, as described above. The second method S200 can further include cleaning or activating the tie layer 120, such as with a corona treatment, ultraviolet ozone treatment, low-pressure plasma, corona discharge, etching, flame treatment, or solvent wipe, as described above. The second method S200 can also include masking a portion of the outer broad face of the substrate 110 that is aligned with the deformable region 131 of the tactile layer 130 in the tactile layer 130 and substrate 110 stack. The second method S200 can therefore further include removing the mask from the inner broad face of the tactile layer 130 and/or from the outer broad face of the substrate 110. However, the second method S200 can include any other procedure implemented in any other way to bond the tactile layer 130 to the substrate 110.
  • However, the substrate 110 and tactile layer stack can be assembled and/or bonded according to any other technique or process.
  • The displacement device 140 of the first dynamic tactile interface Dm is coupled to the fluid channel 113 and is configured to displace fluid through the fluid channel 113 to transition the deformable region 131 from the retracted setting to the expanded setting. Generally, the displacement device 140 can actively displace fluid through the fluid channel 113 and the fluid conduit 114 to outwardly expand the deformable region 131 to transition the deformable region 131 from the retracted setting to the expanded setting. Furthermore, the displacement device 140 can actively remove fluid from the fluid channel 113 and the fluid conduit 114 to inwardly retract the deformable region 131 to transition the deformable region 131 from the expanded setting to the retracted setting. The displacement device 140 can also transition the deformable region 131 to one or more intermediate positions or height settings between the expanded and retracted settings. In the retracted setting, the tactile surface 133 at the deformable region 131 can be in-plane or aligned with the tactile surface 133 at the peripheral region 132. However, in the retracted setting, the deformable region 131 can be positioned at any other height relative the peripheral region 132. In the expanded setting, the tactile surface 133 at the deformable region 131 can be elevated above the tactile surface 133 at the peripheral region 132 such that the expanded setting is tactilely distinguishable from the retracted setting at the tactile surface 133. However, the deformable region 131 can be positioned at any other height relative the peripheral region 132 in the expanded setting.
  • The displacement device 140 can be an electrically-driven positive-displacement pump, such as a rotary, reciprocating, linear, or peristaltic pump powered by an electric motor. Alternatively, the displacement device 140 can be an electroosmotic pump, a magnetorheological pump, a microfluidic pump, a manually-powered pump, such as powered though a manual input provided by the user, or any other suitable device configured to displace fluid through the fluid channel 113 and the fluid conduit 114 to transition the deformable regions between settings, such as described in U.S. Provisional Patent Application No. 61/727,083, filed on 15 Nov. 2012, which is incorporated in its entirety by this reference.
  • As described above and shown in FIG. 2, one variation of the first dynamic tactile interface 100 further includes a touch sensor 170 configured to detect an input at the tactile surface 133. The touch sensor 170 can be a capacitive touch sensor, a resistive touch sensor, an optical touch sensor, a fluid pressure sensor, an acoustic touch sensor, or any other suitable type of sensor. The touch sensor 170 can include a plurality of sensors configured to detect an input at particular regions across the tactile surface 133, including at the deformable region 131. However, the touch sensor 170 can be of any other type, include any other feature or component, and can be patterned across the first dynamic tactile interface 100 in any other way. The touch sensor 170 can be arranged between a display 180 and the substrate 110, as shown in FIG. 2. Alternatively, the display 180 can be a touch display incorporating the touch sensor 170. A portion of the touch sensor 170 can also be coupled to the fluid channel 113, coupled to the fluid conduit 114, or arranged within the substrate 110, such as above or below the fluid channel 113. A portion of the touch sensor 170 can also be arranged within the tactile layer 130. However, all or a portion of the touch sensor 170 can be arranged in any other way within the first dynamic tactile interface 100.
  • One variation of the first dynamic tactile interface 100 incorporates a plurality of deformable regions, each paired with a fluid conduit fluidly coupled to at least one fluid channel, as shown in FIG. 3. In this variation, the first dynamic tactile interface 100 can also include one or more displacement devices coupled to the one or more fluid channels, wherein the displacement devices displace fluid through the one or more fluid channels to transition one or more deformable regions between retracted and expanded settings at any given time. In this variation, the deformable regions can define input keys of a QWERTY keyboard when in the expanded setting. Furthermore, the display 180 can output an image aligned with each deformable region, wherein each image is indicative of an input key associated with each deformable region (e.g., SHIFT, ‘a,’ ‘g,’ or ‘8’). In this variation, when the deformable regions are in the expanded setting, a processor coupled to the touch sensor 170 can identify an input on the tactile surface 133 that substantially inwardly deforms a deformable region as an input request for the input key, whereas the processor can identify an input on the tactile surface 133 that does not substantially inwardly deform the deformable region 131 as a second type of input that is not a request for the input key. However, the first dynamic tactile interface 100 can include any other components arranged in any other way to achieve any other function.
  • In another variation of the first dynamic tactile interface 100, the substrate 110 is physically coextensive with at least one of the display 180 and the touch sensor 170. In this variation, the fluid channel 113 is formed in the interior surface of the tactile layer 130 or is otherwise substantially defined on or within the tactile layer 130. In this variation, the tactile layer 130 is bonded to the substrate 110 at the peripheral region 132, wherein the substrate 110 rigidly retains the peripheral region 132 during setting transitions of the deformable region 131. However, the first dynamic tactile interface 100 can be of any other form and include any other suitable component, film, or layer.
  • One variation of the first dynamic tactile interface 100 is incorporated into an electronic device. The electronic device can be any of an automotive console, a desktop computer, a laptop computer, a tablet computer, a television, a radio, a desk phone, a mobile phone, a personal data assistant (PDA), a personal navigation device, a personal media player, a camera, a watch, a gaming controller, a light switch or lighting control box, cooking equipment, or any other suitable electronic device.
  • 2. Second Dynamic Tactile Interface 200
  • As shown in FIGS. 11A and 11B, a second dynamic tactile interface 200 includes: a substrate 210 including a first transparent material and defining an attachment surface 216, an open channel 213A opposite the attachment surface 216, and a fluid conduit 214 intersecting the open channel 213A and passing through the attachment surface 216; a tactile layer 230 including a second transparent material and defining a tactile surface 233, a peripheral region 232 bonded to the attachment surface 216 opposite the tactile surface 233, and a deformable region 231 adjacent fluid conduit 214 and disconnected from the attachment surface 216; a closing panel 212 bonded to the substrate 210 opposite the attachment surface 216 and enclosing the open channel 213A to define a fluid channel 213B; a working fluid 250; and a displacement device 240 configured to displace the working fluid 250 into the fluid channel 213B and through fluid conduit 214 to transition the deformable region 231 from a retracted setting to an expanded setting, the deformable region 231 flush with the peripheral region 232 in the retracted setting (shown in FIG. 11A) and offset from the peripheral region 232 in the expanded setting (shown in FIG. 11B).
  • As shown in FIG. 12, a method for manufacturing the second dynamic tactile interface 200 includes: creating an open channel in an interior surface of a substrate including a first transparent material and defining an attachment surface 216 opposite the interior surface in Block S310; creating a fluid conduit intersecting the open channel 213A and passing through the attachment surface 216 of the substrate 210 in Block S312; activating the attachment surface 216 in Block S320; selectively bonding a peripheral region of a tactile layer to the attachment surface 216 in Block S322, the tactile layer 230 including a second transparent material and defining a deformable region disconnected from the attachment surface 216 proximal fluid conduit 214; activating the interior surface in Block S330; bonding a closing panel to the interior surface to enclose a portion of the open channel 213A to define a fluid channel in Block S332; coupling a displacement device to the fluid channel 213B in Block S342; and filling the fluid channel 213B with a working fluid in Block S340.
  • Like the first dynamic tactile interface, the second dynamic tactile interface 200 functions to expand and retract one or more deformable regions to intermittently and selectively provide tactile guidance over a touchsensor and/or display of a computing device. For example, second dynamic tactile interface 200 can be implemented in a smartphone, tablet, laptop, PDA, automotive or in-dash console, a desktop computer, a television, a radio, a desk phone, a mobile phone, a personal navigation device, a personal media player, a camera, a watch, a gaming controller, a light switch or lighting control box, cooking equipment, or any other suitable computing or electronic device. The second dynamic tactile interface 200 can also be incorporated in an aftermarket device for a computing device, such as described in U.S. patent application Ser. No. 13/465,772, filed on 7 May 2012, which is incorporated in its entirety by this reference
  • The substrate 210 of the second dynamic tactile interface 200 includes a first transparent material and defines an attachment surface 216, an open channel opposite the attachment surface 216, and a fluid conduit intersecting the open channel 213A and passing through the attachment surface 216. Generally, the substrate 210 functions like the substrate 110 of the first dynamic tactile interface 100 to define an attachment surface 216 that retains a peripheral region of a tactile layer, one or more fluid ports, one or more support members (or support areas) adjacent the fluid ports and deformable regions of the tactile layer 230, and one or more fluid channels that feed fluid into and out of the fluid channels to transition the deformable regions between expanded and retracted settings. The substrate 210 can be substantially transparent and substantially rigid relative to the tactile layer 230 such that changes in fluid pressure within the fluid channel 213B are predominantly absorbed by the deformable region 231 of the tactile layer 230—rather than the substrate 210—thus yielding controlled expansion and retraction of the deformable region 231 of the tactile layer 230.
  • In one implementation, the substrate 210 is a thermoset resin cast in sheet form, such as polycarbonate or a polycarbonate-hybrid polymer. In this implementation, the substrate 210 can begin as a cast polymer sheet of uniform thickness that is post-machined to create the fluid channel 213B and fluid conduit 214. For example, a ball endmill (or endmill of other suitable contour) can be plunged part-way (e.g., through 70% of the thickness of the substrate 210) into the interior surface of the substrate 210 opposite the attachment surface 216. In this example, the ball endmill can then be displaced laterally across the interior surface to cut the open channel 213A of substantially constant depth, as in Block S310 of the method. A tapered endmill (“taper mill”) can then be plunged fully through the substrate 210 normal to the interior surface to create one or more frustoconical bores (i.e., fluid conduits) intersecting the open channel 213A, as in Block S312 of the method. The substrate 210 can then be acid-dipped, flame polished, or otherwise processed to reduce or eliminate machining artifacts in the bore(s) and open channel(s). Therefore, in this example, fluid conduit 214 can include a frustoconical section tapering toward the attachment surface 216, and, once the closing panel 212 is bonded to the interior surface of the substrate 210 to enclose the open channel 213A and thus define the fluid channel 213B, the fluid channel 213B can define a curvilinear cross-section, as shown in FIGS. 13A and 13B.
  • Alternatively, the substrate 210 can be acrylic, glass, urethane, polyurethane, or of any other substantially transparent, translucent, and/or relatively rigid material. The open channel 213A and fluid conduit 214 can also be machined (e.g., drilled), stamped, molded, extruded, laser cut, imprinted, or formed in any other way into the substrate 210, such as described above.
  • The substrate 210 can further define a second open channel opposite the attachment surface 216 and parallel to the fluid channel 213B and a second fluid conduit intersecting the second open channel and passing through the attachment surface 216 adjacent fluid conduit 214 and the deformable region. In this implementation, the substrate 210 can cooperate with the closing panel 212 to enclose the second open channel and thus define a second fluid channel, and the second fluid can also be coupled to the displacement device 240 such that the displacement device 240 can displace the working fluid 250 through both the fluid channel 213B and the second fluid channel (and fluid conduit 214 and the second fluid conduit) to transition the deformable region 231 from the retracted setting to the expanded setting. In this implementation, fluid can similarly drain back into fluid conduit 214 and the second fluid conduit and then into the fluid channel 213B and the second fluid channel, respectively, as the deformable region 231 transitions from the expanded setting back into the retracted setting.
  • The tactile layer 230 of the second dynamic tactile interface 200 includes a second transparent material and defines a tactile surface, a peripheral region bonded to the attachment surface 216 opposite the tactile surface 233, and a deformable region adjacent fluid conduit 214 and disconnected from the attachment surface 216. Generally, the tactile layer 230 functions as an exterior surface of the second dynamic tactile interface 200 (and the computing device) within one or more regions that can be selectively and intermittently deformed to define tactilely-distinguishable formations configured to tactilely guide user input into the computing device. As described above, the tactile layer 230 can be substantially uniform in thickness and composition throughout its thickness and substantially transparent. The tactile layer 230 can also be uniformly elastic and/or flexible relative to the substrate 210 throughout its volume. Alternatively, the tactile layer 230 can be of varying thickness, optical property, or mechanical property throughout its thickness or volume. For example, the tactile layer 230 can feature a well or recess around a perimeter of the deformable region 231 (inside the peripheral region). The tactile layer 230 can be selectively doped across the deformable region 231 to increase elasticity of the deformable region and/or selectively cross-linked to reduce elasticity across the peripheral region.
  • In one implementation, the substrate 210 is formed of a thermoset polymer material (e.g., a polycarbonate-hybrid polymer) of a first elasticity, and the tactile layer 230 is formed of a urethane material of a second elasticity greater than the first elasticity (of the substrate 210 material). In this implementation, the tactile layer 230 and the substrate 210 can be assembled by first cleaning the substrate 210 (e.g., in ultraviolet ozone) and activating the attachment surface 216 of the substrate 210, as in Block S320 of the third method. For example, the attachment surface 216 can be treated with nitrogen surface activation to create nitrogen groups (e.g., nitrates, nitrites) along the attachment surface 216 and at a skin depth (e.g., ˜5 μm) within the substrate 210. The attachment surface 216 can then be masked with an area around the fluid port corresponding to the deformable region 231 exposed and a release compound applied across the mask. Alternatively, the release compound can be printed onto the area around the fluid port corresponding to the deformable region, such as with a two-axis printing head, screen printing, stereo lithography, or other printing technique or apparatus. The release compound can be a mold release wax, water, oil, alcohol, or other suitable material. Yet alternatively, the attachment surface 216 can be selectively activated, including a portion of the attachment surface 216 corresponding to the peripheral region 232 and excluding a portion of the attachment surface 216 corresponding to the deformable region.
  • In the foregoing implementation, once the attachment surface 216 is activated and/or masked proximal fluid conduit 214 and the tactile layer 230 is cleaned (e.g., in ultraviolet ozone, as described above), the peripheral region 232 of the tactile layer 230 can be selectively bonded to the attachment surface 216 of the substrate 210, as in Block S322 of the third method. For example, the substrate 210 and the tactile layer 230 can be laminated together between a set of rollers, as described above, and then placed in an autoclave for a time, temperature, and pressure specified in curing profile. In this example, the substrate 210 and tactile layer stack can be cured in an elevated temperature (e.g., 400° F.) and/or elevated pressure (e.g., 60 psi) environment within the autoclave for a predefined period of time (e.g., one hour), which can cause a bond to grow across the boundary between the substrate 210 and the tactile layer 230 and can reduce the volume of any gas (e.g., air) trapped between the substrate 210 and the tactile layer 230. The curing process can thus yield a stable bond between the substrate 210 and the tactile layer 230 and can reduce optical aberrations between the substrate 210 and the tactile layer 230 caused by trapped gases therebetween. In particular, as the tactile layer 230 and substrate stack cures, polymer chains within the tactile layer 230 can bond to the nitrogen groups along portions of the attachment surface 216 corresponding to the peripheral region, and the release compound (e.g., working fluid) applied to the attachment surface 216 around fluid conduit 214 can locally retard bonding between the tactile layer 230 and the substrate 210 to yield the deformable region 231 adjacent fluid conduit 214 and disconnected from the attachment surface 216.
  • As shown in FIGS. 14A and 14B, one variation of the second dynamic tactile interface 200 includes an ink bezel 260 arranged about a perimeter of the attachment surface 216 between the substrate 210 and the tactile layer 230. In this variation, the ink bezel 260 can be substantially opaque and thus define an opaque border around the second dynamic tactile interface 200. For example, the ink bezel 260 can mask (i.e., hide from view) traces and a ribbon connector for a touch sensor coupled to the closing panel 212 opposite the substrate 210. The ink bezel 260 can also mask a via 218 in the closing panel 212 (shown in FIG. 14A) that feeds fluid from the displacement device 240 into the fluid channel 213B, as described below. The ink bezel 260 can be applied along the entire perimeter of the attachment surface 216 or along one or a subset of edges of the attachment surface 216. The ink bezel 260 can also be of similar or dissimilar width from each edge of the attachment surface 216. For example, for the second dynamic tactile interface 200 implemented within a smartphone, the ink bezel 260 can be 0.20″ wide along the vertical edges of the attachment surface 216 and 0.80″ wide along the horizontal edges of the attachment surface 216.
  • One variation of the third method can therefore include applying an ink bezel around a perimeter of the attachment surface 216 in Block S324, as shown in FIG. 15. In the foregoing implementation, the ink bezel 260 can be applied to the attachment surface 216 prior to assembly of the tactile layer 230 over the substrate 210 such that the substrate 210 and the tactile layer 230 cooperate to substantially enclose the ink bezel 260. For example, once the substrate 210 is cleaned and the attachment surface 216 activated, a black ink in an alcohol or epoxy suspension can be printed or rolled onto the attachment surface 216 in a substantially uniform thickness to yield suitably minimal local light transmission. The tactile layer 230 can then be laminated over the ink and the attachment surface 216 and cured, as described above. In this implementation, which the tactile layer 230, substrate, and ink bezel stack cures, the ink bezel 260 can flow or deform at its interior edge proximal the junction between the tactile layer 230, substrate, and ink bezel (e.g., due to elevated temperature in the autoclave) to form a smooth transition between the tactile layer 230, substrate, and ink bezel, as shown in FIGS. 14A and 14B.
  • Alternatively, the ink bezel 260 in the form of an uncured black epoxy sheet or a black urethane sheet can be trimmed to size and applied over the attachment surface 216, applied to the interior surface of the tactile layer 230, or inserted between the substrate 210 and the tactile layer 230 prior to bonding. Yet alternatively, the ink bezel 260 can be applied to or inserted between the interior surface of the substrate 210 and the closing panel 212 with similar techniques or methods.
  • The closing panel 212 of the second dynamic tactile interface 200 is bonded to the substrate 210 opposite the attachment surface 216 and encloses the open channel 213A to define a fluid channel. The closing panel 212 can be of a material similar to that of the tactile layer 230 such that the closing panel 212 can be bonded to the substrate 210 with a technique or method similar to that described above to bond the tactile layer 230 to the substrate 210. For example, both the closing panel 212 and the tactile layer 230 can be of urethane, but the tactile layer 230 can be a urethane material of a higher elasticity (e.g., lower durometer or Shore hardness) than the urethane material of the closing panel 212 such that the tactile layer 230 is more prone to deformable at the deformable region 231 than the closing panel 212 proximal the open channel 213A when fluid pressure within the fluid channel 213B changes. The closing panel 212 can also be of a uniform thickness similar to that of the tactile layer 230. Alternatively, the closing panel 212 can be substantially thick (i.e., thicker than the tactile layer 230) to resist outward deformation proximal the open channel 213A when fluid pressure within the fluid channel 213B increases. Yet alternatively, the closing panel 212 can be substantially thin (i.e., thinner than the tactile layer 230) to function as an interface layer to close the open channel 213A and to bond the interior surface of the substrate 210 to a more rigid panel, such as to a capacitive touch panel with a PMMA substrate or to a display with a glass substrate that support the closing panel 212 against deformation when the fluid pressure within the fluid channel 213B changes. Furthermore, like the tactile layer 230 and the substrate 210, the closing panel 212 can be substantially transparent to enable light transmission therethrough, such as from a display coupled to the second dynamic tactile interface 200 as described above.
  • In the implementation described above in which the substrate 210 is formed of a polycarbonate-hybrid material and the tactile layer 230 is formed of a urethane material of an elasticity greater than that of the substrate 210, the closing panel 212 can be formed of a urethane material similar to that of the tactile layer 230 but of an elasticity less than that of the tactile layer 230. In this implementation, the closing panel 212 can be bonded to the substrate 210 with a techniques or methods similar to those described above to bond the tactile layer 230 to the substrate 210. In particular, the interior surface of the substrate 210 can be cleaned and then activated, as in Block S330 of the third method. For example, the interior surface can be cleaned in ultraviolet ozone and then treated with nitrogen surface activation as described above. As in Block S332 of the third method, the closing panel 212 can be similarly cleaned and then laminated to the interior surface of the substrate 210, such as described above, to enclose a portion of the open channel 213A, thereby defining the fluid channel 213B. The substrate 210 and the closing panel 212 can then be cured, such as according to a cure schedule similar to that described above.
  • In the foregoing implementation, the interior surface and the attachment surface 216 of the substrate 210 can be prepared for bonding with the tactile layer 230 and the closing panel 212 substantially simultaneously. For example, the interior surface can be cleaned, then the substrate 210 flipped and the attachment surface 216 cleaned. The interior surface can subsequently be activated, then the substrate 210 flipped and the attachment surface 216 activated. The substrate 210 can then be placed between both the tactile layer 230 and the closing panel 212 and the stack laminated (e.g., through a set of rollers) prior to placement in an autoclave for curing. Alternatively, the substrate 210 and the tactile layer 230 can be bonded and cured, and then the substrate 210-tactile layer stack bonded to the closing panel 212 and cured, or vice versa. However, the tactile layer 230, substrate, and closing panel (and ink bezel) can be prepped and bonded—and the corresponding Blocks of the third method can be performed—in any other suitable order.
  • In one implementation, the closing panel 212 includes a via configured to communicate fluid between the displacement device 240 and the fluid channel 213B. In the variation of the second dynamic tactile interface 200 that includes the ink bezel 260 between the substrate 210 and the tactile layer 230, the closing panel 212 can define the via 218 behind the ink bezel 260 such that the via 218 is not optically visible through the tactile layer 230. In this implementation, the via 218 can be created in the closing panel 212 prior to bonding the closing panel 212 to the substrate 210, as in Block S334 of the third method shown in FIG. 15. For example, the via 218 can be stamped, machined, drilled, etched (e.g., bulk micro-machined), laser cut, or otherwise formed in the closing panel 212, and the closing panel 212 can then be acid washed, flame polished, or otherwise processed to reduce or eliminates manufacturing artifacts leftover from creation of the via 218. The closing panel 212 can then be aligned with and bonded to the interior surface of the substrate 210 with the via 218 adjacent the open channel 213A (i.e., the fluid channel 213B) such that working fluid can be communicated through the via 218 and into the fluid channel 213B. Alternatively, the via 218 can be created in the closing panel 212 after the closing panel 212 is bonded to the substrate 210.
  • The second dynamic tactile interface 200 also includes a working fluid. Generally, the displacement device 240 functions to displace the working fluid 250 into the fluid channel 213B, thereby increasing fluid pressure within the fluid channel 213B and fluid conduit 214 and thus causing the deformable region 231 of the tactile layer 230 to expand outwardly. The displacement device 240 can also release fluid pressure within the fluid channel 213B and/or actively pump fluid out of the fluid channel 213B to enable the deformable region 231 to retract, as described above.
  • The working fluid 250 can be substantially transparent, such as exhibiting a refractive index, Abbe number, and/or chromatic dispersion properties similar to those of the substrate 210 in order to limit diffraction, refraction, and reflection of light within the second dynamic tactile interface 200 at interfaces between the working fluid 250 and the substrate 210 (e.g., at a surface of the fluid channel 213B or at a surface of fluid conduit 214). For example, the working fluid 250 can be water, an alcohol, or an oil.
  • In one implementation, the working fluid 250 is a silicone oil that is substantially incompressible and exhibits low vapor pressure. In this implementation, the base material of the tactile layer 230 can tend to adsorb or “uptake” the working fluid 250, and the tactile layer 230 can thus incorporate a barrier sublayer 236 that is impermeable to the working fluid 250 to limit working fluid uptake into the tactile layer 230. For example, the tactile layer 230 can include a first sublayer 235 (bonded to the substrate 210), a barrier sublayer 236 bonded to the first sublayer 235, and a second sublayer 237 bonded to the barrier sublayer 236 opposite the first sublayer 235, as shown in FIGS. 16A and 16B. In this example, the first and second sublayer 237 s can be of the same or similar urethane material, and the barrier sublayer 236 can be nylon, (high-density) polyethylene, or any other suitable plastic that is substantially impermeable to silicone oil. Furthermore, in this example, the barrier sublayer 236 can be substantially thin to enable light transmission through the tactile layer 230 with minimal internal reflection, refraction, or diffraction, and the first sublayer 235 can be substantially thin to minimize a volume of the material over the deformable region 231 that can adsorb the working fluid 250, as shown in FIG. 16B. The second sublayer 237 can thus be substantially thicker than the barrier sublayer 236 and/or the first sublayer 235 to yield suitable strength, elasticity, abrasion resistance, etc. to the tactile layer 230 and the tactile surface 233.
  • In the foregoing implementation, the second sublayer 237 can alternatively be of a polymer material different from that of the first sublayer 235. For example, the first sublayer 235 can be of urethane of a first elasticity, and the second sublayer 237 can be of a polycarbonate-based material of a second elasticity less than the first elasticity. In this example, the first sublayer 235 can thus function as a buffer backing that absorbs sharp deformation of the tactile layer 230 proximal a perimeter of the deformable region, such as described above, and the second layer can yield improved abrasion resistance, gloss or sheen, tactile smoothness, etc. However, the working fluid 250 can be of any other liquid (or gas), and the tactile layer 230 can be of any other number of sublayers of any other material and geometry to limit uptake of working fluid into the tactile layer 230. However, the tactile layer 230 can be of any other form, any other material, and bonded to the substrate 210 within any other technique or method. The closing panel 212 and the substrate 210 can similarly be of any other suitable material can assembled within the second dynamic tactile interface 200 in any other suitable way.
  • The third method can therefore include Block S340, which recites filling the fluid channel 213B with a working fluid in Block S340. In one implementation, the closing panel 212 includes a draw port coupled to the fluid channel 213B at one end of the fluid channel 213B opposite the via 218. In this implementation, once the substrate 210, closing panel, tactile layer, and displacement device are assembled, a valve is connected between an inlet of the displacement device 240 (or connected reservoir) and an external reservoir containing working fluid. With the valve closed, gas (e.g., air) is then evacuated from the fluid channel 213B through the draw port. Once a threshold vacuum in reached within the fluid channel 213B, the valve is opened and working fluid is drawn from the external reservoir into the displacement device 240, through the via 218, and into the fluid channel 213B and fluid conduit. Any remaining gas within the second dynamic tactile interface 200 can be subsequently purged by supporting the second dynamic tactile interface 200 vertically with the draw port above the via 218 and displacing a small volume of working fluid into and out of the second dynamic tactile interface 200 to dislodge and draw remaining (air) bubbles out of the second dynamic tactile interface 200 through the draw port. The draw port is finally disconnected from the valve and sealed, and the displacement device 240 (or connected reservoir) is similarly sealed, thus isolating the working fluid 250 in the second dynamic tactile interface 200. However, Block S340 can function in any other way to evacuate gas from the fluid channel 213B, to inject working fluid into the second dynamic tactile interface 200, and/or to purge any remaining gas from the second dynamic tactile interface 200.
  • As shown in FIGS. 14A and 14B, one variation of the second dynamic tactile interface 200 includes a touch sensor 270 configured to output a signal corresponding to an input on the tactile surface 233. As described above, the touch sensor 270 can be a capacitive touch sensor, a resistive touch sensor, or any other suitable type of sensor arranged on or across a sensor panel.
  • In one implementation, the assembled substrate, closing panel, and substrate—hereinafter the “stack”—is bonded to the sensor panel. The third method can therefore include Block S350, which recites laminating the closing panel 212 opposite the substrate 210 to a touch sensor panel and curing the closing panel 212 and the touch sensor 270 panel under elevated pressure and elevated temperature, as shown in FIG. 15. In one example, the sensor panel includes a polymer sheet (e.g., a PMMA or glass sheet) patterned on each side with indium tin oxide (ITO) traces to form a capacitive touch sensor. In this example, an optically-clear adhesive (OCA) can be sprayed or rolled across the closing panel 212 opposite the substrate 210 and/or across a broad face of the sensor panel (and over the ITO traces), and the sensor panel and the stack can be laminated together. Alternatively, a sheet of uncured OCA can be inserted between the stack and the sensor panel. The stack, OCA, and sensor panel can then be cured, such as in an autoclave at a predefined temperature and pressure for a predefined period of time, to adhere the sensor panel to the stack. In this example, the peak temperate of the autoclave during the curing process can be kept substantially below a flow temperature, evaporation temperature, oxidation temperature, etc. of the ITO or other trace, feature, or material within the sensor panel to substantially eliminate potential for damage to the sensor panel during the assembly process. In particular, the substrate 210, the tactile layer 230, and the closing panel 212 can be assembled into the stack and cured before the sensor panel in bonded to the stack.
  • Alternatively, the closing panel 212 and the sensor panel can be physically coextensive, wherein the sensor panel is bonded directly to the substrate 210. For example, the touch panel can include a series of ITO traces patterned across each side of a urethane sheet, which is laminated to the substrate 210 and tactile layer assembly and cured in an autoclave at a peak temperate that does not yield substantially distortion or damage to the ITO traces, such as described above. However, the second dynamic tactile interface 200 can include a touch sensor of any other type and can be bonded or coupled to the closing panel 212 and/or substrate in any other suitable way.
  • As shown in FIG. 15, one variation of the second dynamic tactile interface 200 includes a display 280 bonded to the closing panel 212 opposite the tactile layer 230 with an optically-clear adhesive. Generally, the display 280 is configured to render an image of an input key proximal the deformable region, as described above. In one implementation, the display 280 is bonded directly to closing panel, such as by sandwiching a sheet of OCA between the stack and the display 280 and curing the OCA, as described above. One variation of the third method can therefore in include Block S352, which recites bonding a display to the touch sensor 270 panel opposite the closing panel 212 with an optically-clear adhesive. In this implementation, the display 280 can be a touchscreen that incorporates both a display and a (touch) sensor. Alternatively, in the variation of the second dynamic tactile interface 200 in which a touch sensor is bonded the closing panel 212, the display 280 can be bonded to the touch sensor 270 opposite the closing panel 212, such as by adhering the display 280 to the sensor panel with an OCA. In this implementation, the display 280 can be bonded to the sensor panel after or while the sensor is bonded to the stack. Alternatively, the display 280 and the sensor panel can be assembled and subsequently bonded to the stack, such as described above. However, the second mobile computing device can include any other type of display and/or touch sensor coupled or bonded to the substrate 210, tactile layer, and/or closing panel in any other suitable way.
  • The displacement device 240 of the second dynamic tactile interface 200 is configured to displace the working fluid 250 into the fluid channel 213B and through fluid conduit 214 to transition the deformable region 231 from a retracted setting to an expanded setting. As described above, the displacement device 240 generally functions to pump fluid into the fluid channel 213B transition the deformable region 231 from flush with the peripheral region 232 in the retracted setting and to offset from the peripheral region 232 in the expanded setting. In one implementation, the displacement device 240 is coupled to the via 218 in the closing panel 212, as described above. The third method can therefore include Block S342, which recites coupling the displacement device 240 to the via 218. For example, the displacement device 240 can include a positive displacement pump coupled to the via 218 by a flexible hose extending from the via 218.
  • Alternatively, the displacement device 240 can include a flexible membrane bonded to the closing panel 212 around the via 218 and opposite the substrate 210 to define a reservoir filled with the working fluid 250. In this implementation, the displacement device 240 can compress the flexible membrane to displace fluid through the via 218 and into the fluid channel 213B to transition the deformable region 231 into the expanded setting. However, the displacement device 240 can be of any other form and can be fluidly coupled to the fluid channel 213B in any other suitable way. The displacement device 240 can also transition the deformable region 231 of the tactile layer 230 to any other position above or below the peripheral region 232 of tactile layer.
  • However, the second dynamic tactile interface 200 can include any number of displacement devices and can define any number of vias, fluid channels, fluid conduits, valves, and/or deformable regions that can be selectively and intermittently transitioned between retracted and expanded settings to provide tactile guidance over any other suitable computing device. Similarly, the third method can implement any other method or technique to manufacture and assemble the second dynamic tactile interface 200.
  • As a person skilled in the art will recognize from the previous detailed description and from the figures and claims, modifications and changes can be made to the embodiments of the invention without departing from the scope of this invention as defined in the following claims.
