  • Patent number: 9557813
    Abstract: One variation of a method for reducing perceived optical distortion of light output through a dynamic tactile interface includes: rendering an image on a digital display coupled to a substrate opposite a tactile layer, the tactile layer defining a tactile surface, a peripheral region, and a deformable region adjacent the peripheral region, disconnected from the substrate, and operable between a retracted setting and an expanded setting, the deformable region substantially flush with the peripheral region in the retracted setting and offset above the peripheral region in the expanded setting; estimating a viewing position of a user relative to the digital display; transitioning the deformable region from the retracted setting into the expanded setting; and modifying the portion of the image rendered on the digital display according to the estimated viewing position of the user and a profile of the tactile surface across the deformable region in the expanded setting.

  • Publication number: 20170024054
    Abstract: A device having a dynamic tactile interface communicates with an external electronic device to provide tactile output (e.g., tactile display) based on communication with the external electronic device. Data is tactilely displayed on a computing device. Data is received from an external electronic device. The data is converted into a tangible data structure and a portion of a dynamic tactile layer is deformed corresponding to the tangible data structure. The dynamic tactile layer is arranged over a surface of the computing device and includes a set of deformable regions, wherein each deformable region deforms into an elevated tactile formation. The portion of the dynamic tactile layer includes a subset of deformable regions in the set of deformable regions.

  • Publication number: 20160239137
    Abstract: A method for registering user interaction with a dynamic tactile interface, which includes a tactile layer defining a tactile surface, a deformable region, and a peripheral region and coupled to a substrate opposite the tactile surface, the deformable region cooperating with the substrate to form a variable volume. The method includes detecting a first contact of an object at a first location on the tactile surface at a sensor; detecting a removal of the object from the first location; at a first time, detecting a first pressure of the variable volume at a pressure sensor; at the sensor, at a second time after the first time, detecting a second contact at a second location; at the second time, detecting a second pressure at the pressure sensor; interpreting the first and second contact, and the pressure difference as a gesture; and executing a command corresponding to the gesture.

  • Publication number: 20160221316
    Abstract: A touch layer for a mobile computing device includes a substrate defining a surface, a first polymer layer and a second polymer layer. The first polymer layer includes a first modulus and is arranged across the surface. The second polymer layer includes a polymer of a second modulus less than the first modulus and is arranged across the first polymer layer opposite the substrate. The touch layer also includes a low-friction coating applied across the second polymer layer opposite the first polymer layer. The touch layer exhibits a self-repair property to repair damage to one of the polymer layers or the low-friction layer. The self repair may be implemented by material flow or diffusion, heat activated or time-release, and may return a surface of the touch display to near its original condition.

  • Publication number: 20160188068
    Abstract: Input is detected on a dynamic tactile interface based on pressure events and touch sensor outputs. The dynamic tactile interface includes a touch sensor, a pressure sensor, and a compressible material. When both a pressure event and touch sensor output are correlated to identify an input, the input is processed by a display device associated with the dynamic tactile interface. The flexible material may be implemented as a variable volume associated with a deformable region, such that when the deformable region is depressed the variable volume decreases and the pressure sensor detects increased pressure. The flexible material may be implemented as a compressible layer between two layers that comprise the touch sensor, such that when an input is received on an upper layer of the touch sensor, the middle layer having the flexible volume may compress. The multi-layer touch sensor can be a capacitance touch or resistive touch sensor.

  • Publication number: 20160162064
    Abstract: One variation of the method includes registering interaction with a dynamic tactile interface including a tactile layer and a substrate, the tactile layer defining a tactile surface, a deformable region, and a peripheral region adjacent the deformable region and coupled to the substrate opposite the tactile surface, the method including: detecting an orientation of the device; predicting a location of an upcoming input related to a native application executing on the device; selecting a particular deformable region from a set of deformable regions, the particular deformable region substantially coincident the input location; selectively transitioning the particular deformable region from a retracted setting into an expanded setting, the deformable region substantially flush with the peripheral region in the retracted setting and tactilely distinguishable from the peripheral region in the expanded setting; and detecting an input, corresponding to the upcoming input, on the particular deformable region.
