  • Patent number: 10705595
    Abstract: Described herein are various embodiments for enabling realistic haptic feedback for virtual three-dimensional (3D) objects. A real proxy surface is provided for a virtual object, where the proxy surface may be a relief surface, such as a depth-compressed model of the virtual object. In an exemplary method, when a user touches a proxy surface, a position of the touch point on the surface is detected. The touch point is mapped to a corresponding point on the virtual object. A position of the virtual object is determined such that the touch point is in alignment with the corresponding point on the virtual object, and the virtual object is displayed at the first determined position on an augmented reality display. As a result, a user touching the proxy surface may have the sensation of touching a solid version of the virtual 3D object instead of the proxy surface.

  • Patent number: 10685538
    Abstract: A system providing various improved processing techniques for haptic feedback is described. An acoustic field is defined by one or more control points in a space within which the acoustic field may exist. Each control point is assigned an amplitude value equating to a desired amplitude of the acoustic field at the control point. Transducers are then controlled to create an acoustic field exhibiting the desired amplitude at each of the control points. When human skin interacts with the acoustic field, vibrations of the skin are interpreted by mechanoreceptors being excited and sending signals to the brain via the nervous system. Improved processing techniques allow for more efficient real-world operation.

    Abstract: To allow the driver to identify a notification vibration even in a situation in which the notification vibration may be masked depending on the road conditions. A vehicle notification device (1) randomly extract one of a plurality of pieces of signal data by the number of vibrators (exciters EX1 to EX4), each of the pieces of signal data being different in a combination of an initial frequency and a target frequency and generates a plurality of sweep signals by changing the frequency from the initial frequency to the target frequency of the extracted piece of signal data in cycles. A plurality of notification vibrations whose frequencies change in different frequency ranges are outputted by outputting the generated sweep signals, individually from the vibrators (exciters EX1 to EX4).

  • Patent number: 10481638
    Abstract: An electronic device has a structure in which two portions between which a bent portion of a display panel is positioned are each fixed to a housing. The electronic device takes two forms of a form in which the display panel is opened and a form in which the display panel is folded in three. The electronic device includes a mechanism for sliding two housings parallel to each other. The display panel is changed in shape so that a portion where a display surface of the display panel is convexly curved and a portion where the display surface of the display panel is concavely curved in the folded state move in directions parallel and opposite to each other. At this time, the two portions of the display panel which are supported by the housings are slid while their display surfaces maintain a state parallel to each other.

  • Patent number: 10475334
    Abstract: An accessible pedestrian pushbutton station. The station includes an articulating rear mounting structure to facilitate accurate positioning of the station on either a curved or flat surface. Additionally, slots in the rear mounting structure allow for minor positional adjustments during installation. The crossing direction arrow is easily repositioned on the front of the station without disassembling the housing. After removing the screw-mounted arrow, the plunger can be turned clockwise or counter-clockwise using only a flat-head screw driver. The plunger is balanced between oppositely biased springs. The spring-balanced plunger indirectly actuates an offset piezo bender using a flexible spring actuator and a second, offset stem bumper. This protects the piezo bender from direct pressure and potential damage. The station includes an internal speaker and the housing includes bilateral sound vents to project the sound emitted by the speaker. Baffles may be inserted in one or both of the sound vents.

  • Patent number: 10474236
    Abstract: A haptic glove comprises a glove body including a glove digit corresponding to a phalange of a user hand with the glove digit having a bend location that is located along the glove digit. A haptic apparatus is coupled to the glove body at the bend location with the haptic apparatus comprising a plurality of sheets that are flexible and inextensible and a pressure actuator coupled to one or more of the plurality of sheets. The plurality of sheets are stacked and configured to translate relative to each other along the centerline with bending of the glove digit. The pressure actuator is configured to adjust an applied pressure to the plurality of sheets to adjust friction between the sheets. The adjustment of friction is proportional to a bending resistance of the glove digit.

  • Patent number: 10431057
    Abstract: A haptic conversion system is provided that intercepts frames of audio data, such as a digital audio signal, converts the frames into a haptic signal, and plays the created haptic signal through an actuator to produce haptic effects. The haptic signal is based on a maximum value of each audio data frame, which defines a magnitude of the haptic signal. The haptic signal is applied to the actuator configured to receive the haptic signal, where the actuator utilizes the haptic signal to generate the one or more haptic effects.

  • Patent number: 10431119
    Abstract: Braille cells and assemblies include an actuator that engages and makes readable a Braille dot by moving a shaft on a base to engage the dot. An electro-permanent magnet and a separate magnetic plate on the shaft can cause the rotation. By running an electric pulse through the electro-permanent magnet, it will rotate the shaft about a pivot under attraction to the magnetic plate. The shaft then engages tactile with the Braille dot to make it and potentially other dots form a Braille character. An electric pulse in an opposite direction may cause the magnetic field to cease and the tactile pin to disengage. The electro-permanent magnet may be coupled a mesh of rows and columns each with a P-channel MOSFET and N-channel MOSFET on opposite ends. The magnet may be at an intersection of a row and a column with diodes, which may be Zenner diodes.

  • Patent number: 10431118
    Abstract: Braille cells and assemblies include an actuator that engages and makes readable a Braille dot by rotating about a hinge on a base to engage the dot. An electro-permanent magnet on the rod and a magnetic plate on the underlying base can cause the rotation. By running an electric pulse through the electro-permanent magnet, it will rotate the rod about the pivot hinge under attraction to the magnetic plate at the other end of the base. The rod then engages with a tactile pin contacting the Braille dot and making it readable. An electric pulse in an opposite direction may cause the magnetic field to cease and the tactile pin to disengage. The electro-permanent magnet may be coupled a mesh of rows and columns each with a P-channel MOSFET and N-channel MOSFET on opposite ends. The magnet may be at an intersection of a row and a column with diodes.
