  • Publication number: 20140218185
    Abstract: A system in which haptic effects are generated using an actuator receives a frequency response for the actuator at a standard voltage and generates a lookup table for an overdrive voltage based on the frequency response. The system then receives a haptic signal for the haptic effect and extracts one or more frequencies for the haptic signal. The system then determines the corresponding overdrive voltage from the lookup table for each of the frequencies and, for each of the frequencies, applies the corresponding overdrive voltage to the actuator. The overdrive voltage is greater than or equal to the standard voltage.

  • Publication number: 20140139327
    Abstract: To maintain consistency in different environments with different impedances, a high voltage current driver may be used as a signal generator to output a tactile signal with a constant current. The constant current ensures that the voltage between the user's finger and the object's surface or electrode remains the same even if impedances in the electrical path change. Specifically, the current driver includes a current sensing circuit that determines the average current being generated. Using a feedback loop, the measured current is compared to a reference current to determine if the correct tactile sensation is perceived by the user. As the impedance changes, the current driver detects the resulting change in the signal's current and adjusts the voltage amplitude of the generated tactile signal in order to match the measured current to the reference current.

    Abstract: An apparatus for producing an electrosensory sensation to a body member (120). The apparatus comprises one or more conducting electrodes (106), each of which is provided with an insulator (108). When the body member (120) is proximate to the conducting electrode, the insulator prevents flow of direct current from the conducting electrode to the body member. A capacitive coupling over the insulator (108) is formed between the conducting electrode (106) and the body member (120). The conducting electrodes are driven by an electrical input which comprises a low-frequency component (114) in a frequency range between 10 Hz and 500 Hz. The capacitive coupling and electrical input are dimensioned to produce an electrosensory sensation. The apparatus is capable of producing the electrosensory sensation independently of any mechanical vibration of the one or more conducting electrodes (106) or insulators (108).

  • Publication number: 20140125467
    Abstract: A system is provided that encodes one or more dynamic haptic effects. The system defines a dynamic haptic effect as including a plurality of key frames, where each key frame includes an interpolant value and a corresponding haptic effect. An interpolant value is a value that specifies where an interpolation occurs. The system generates a haptic effect file, and stores the dynamic haptic effect within the haptic effect file.

  • Patent number: 8717152
    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: 8717151
    Abstract: Methods and devices provide a tactile output surface that can communicate information to users via their sense of touch. The tactile output surface may include a plurality of tactile elements which may be activated to represent various information in a manner that can be understood by touching the device. A mobile device may present tactile output surfaces on one or multiple surfaces, and the user may touch the device after of tactile feedback functionality to obtain information from the one or more tactile output surfaces. In an embodiment, a mobile device may be configured to obtain information from an information source and present the information on a tactile output surface so that the user can perceive the information without having to look at the device. A variety of technologies may be used to create actuatable tactile elements.

  • Patent number: 8717153
    Abstract: The present invention relates to a haptic scroll wheel switch for a vehicle which includes a haptic wheel holder, a haptic wheel, a motor, and an encoder slit. The haptic wheel is rotatably installed in the haptic wheel holder and has a bevel gear unit formed on its one side. The motor is installed in the haptic wheel holder and has a driving shaft and an encoder slit installed on its both ends. More specifically, the driving shaft and the encoder slit are rotated and driven while operating in conjunction with the motor. Furthermore, a pinion gear is fixed to the driving shaft of the motor and geared with the bevel gear of the haptic wheel so that the pinion gear is operated in conjunction with the bevel gear, and a printed circuit board is used in conjunction with a sensor for detecting a rotation of the encoder slit.

  • Publication number: 20140118125
    Abstract: A haptic conversion system is provided that receives a plurality of audio streams of an audio signal. The haptic conversion system further determines, for each stream of the plurality of streams, whether at least one parameter of the one or more parameters indicates that the corresponding stream is to be converted into a haptic effect, and thus, identifies one or more streams that include at least one parameter that indicates the corresponding stream is to be converted into the haptic effect. The haptic conversion system further generates, for the identified streams, a haptic signal based on each corresponding stream. The haptic conversion system further sends, for the identified streams, each haptic signal to an actuator to generate a haptic effect.

  • Publication number: 20140118126
    Abstract: An apparatus and method for controlling a haptic actuator. A haptic actuator controller can includes driver input amplifier, an actuator feedback amplifier, an actuator driver, and a gain controller. The actuator driver is configured to drive a haptic actuator based on a difference of output of the input amplifier and output of the actuator feedback amplifier. The gain controller is configured to determine a boost interval for initiating motion of the haptic actuator, the boost interval based on a boost threshold back-electromotive-force (BEMF) voltage value exceeding a BEMF voltage generated by the haptic actuator. The gain controller is also configured to apply boost gains in the input amplifier and the feedback amplifier during the boost interval. The boost gains are higher than gains applied subsequent to the boost interval to maintain motion of the haptic actuator.

  • Patent number: 8710967
    Abstract: In one example, information is presented to a user in a non-visual manner. In this example, a list of visually representable items defined by a beginning and at least one of dimension of time and space is accessed. Each of the visually representable items within the dimension is placed in one of a plurality of non-visual sensory categories. A non-visual sensory preview is rendered, in sequence for each item in the list, from the plurality of non-visual sensory categories.

    Abstract: Methods and apparatus to provide haptic feedback are disclosed. One example method includes receiving a goal condition at a mobile device, requesting information from a host device using a first close-proximity communication, receiving the information at a mobile device using a second close-proximity communication, determining a level of haptic feedback based on the received information and the goal condition, and causing a haptic effect on the mobile device based on the level of haptic feedback. Other implementations are possible.
