  • Patent number: 9997032
    Abstract: A system is provided that controls an offline haptic conversion. The system receives an input from a source. The system further converts the input into haptic signals. The system further encodes the haptic signals. The system further stores the haptic signals within the source, where the haptic signals are combined with the input within the source. Alternately, rather than encoding the haptic signals and storing the haptic signals within the source, the system handles the haptic signals separately, independent of the source.

  • Publication number: 20180150140
    Abstract: A system that generates a haptic effect using an Eccentric Rotating Mass (“ERM”) actuator determines a back electromotive force (“EMF”) of the ERM actuator during operation of the device and receives a haptic effect signal including one or more parameters, where one of the parameters is a voltage amplitude level as a function of time. Based on the determined back EMF, the system determines if the ERM actuator is spinning and varies the voltage amplitude level based on the back EMF to generate a varied haptic effect signal, where the varying includes, when the ERM actuator is determined to be spinning, reducing the voltage amplitude level compared to when the ERM actuator is determined to not be spinning. The system then applies the varied haptic effect signal to the ERM actuator.

  • Publication number: 20180143689
    Abstract: A method and apparatus for generating haptic surface texture with a deformable surface layer are disclosed. The haptic device includes a flexible surface layer, a haptic substrate, and a deforming mechanism. The flexible surface layer is made of elastic materials and is capable of reconfiguring its surface characteristics. The haptic substrate, in one embodiment, provides a first pattern in response to a first activating signal. Alternatively, the haptic substrate is capable of providing a second pattern in accordance with a second activating signal. The deforming mechanism is configured to change the flexible surface from a first surface characteristic to a second surface characteristic in accordance with the first pattern.

  • Publication number: 20180136731
    Abstract: A signal associated with multiple haptic effects is received, each haptic effect from the multiple haptic effects being associated with a time slot from multiple time slots. Each haptic effect from the multiple haptic effects is associated with an effect slot from multiple effect slots at least partially based on the time slot associated with that haptic effect. An output signal is sent for each effect slot from the multiple effect slots, when the associated haptic effect is scheduled for its time slot.

  • Patent number: 9971428
    Abstract: Devices, systems and methods for using corrugated tessellation to create surface features are disclosed. In embodiments, a device comprises a touch-sensitive surface capable of being in a first configuration and a second configuration different than the first configuration. When the touch-sensitive surface is in the second configuration an input device may be provided that is not present when the touch-sensitive surface is in the first configuration. For example, the touch-sensitive surface can be a flat surface in the first configuration and can be a three-dimensional surface comprising a physical keyboard in the second configuration. In embodiments, a device, such as a mobile phone or a tablet computer, comprises a touch-sensitive display that comprises the touch-sensitive surface.

  • Publication number: 20180081445
    Abstract: A haptic peripheral includes a housing with a frame having a plurality of circumferentially-spaced apart windows, a plurality of deformable membranes positioned within the plurality of circumferentially-spaced apart windows, and a haptic output device disposed within the housing and coupled to the plurality of deformable membranes. The haptic output device includes a motor, a converter, and a plurality of radially-extending pins. Each radially-extending pin has a first end attached to the converter and a second opposing end attached to a deformable membrane. The motor is configured to receive a control signal from a processor and is configured to rotate relative to the housing in response to the control signal. The converter converts rotary motion of the motor to linear motion to move the plurality of radially-extending pins to thereby radially extend the deformable membranes relative to the housing and provide a haptic effect to a user of the haptic peripheral.

  • Publication number: 20170352356
    Abstract: Embodiments that generate multiple haptic effects receive a first haptic effect signal having a first priority and corresponding to a first haptic effect, and receive a second haptic effect signal having a second priority and corresponding to a second haptic effect. When the first priority is less than the second priority, embodiments generate an interaction parameter using the second haptic effect signal. When the second priority is less than the first priority, embodiments generate the interaction parameter using the first haptic effect signal. Embodiments then apply a drive signal to a haptic output device according to the interaction parameter, where the drive signal causes the first haptic effect and the second haptic effect to be generated by the haptic output device concurrently.

  • Patent number: 9788298
    Abstract: Examples of devices, systems, and methods to provide visuo-haptic notifications are disclosed. In one example, a visuo-haptic notification is provided by using a surface. A signal to cause an actuator to change a position of notification portion of the surface from an original position to a notification position is generated and output to the actuator to provide the visuo-haptic notification. In some examples, the notification portion of the surface has a display. The display may be visible when the notification portion of the surface is in the notification position and not visible when the notification portion of the surface is in the original position. At least part of the visuo-haptic notification can be provided on the display.

  • Patent number: 9786287
    Abstract: A system is provided that produces haptic effects. The system receives an audio signal that includes a low-frequency effects audio signal. The system further extracts the low-frequency effects audio signal from the audio signal. The system further converts the low-frequency effects audio signal into a haptic signal by shifting frequencies of the low-frequency effects audio signal to frequencies within a target frequency range of a haptic output device. The system further sends the haptic signal to the haptic output device, where the haptic signal causes the haptic output device to output one or more haptic effects.
