A game controller including a housing with a first handgrip and a second handgrip is provided. The game controller includes a first vibration actuator integrated within the housing proximate to the first handgrip. Further included is a second vibration actuator integrated within the housing proximate to the second handgrip. A controller device is included and is configured to communicate one or more vibrational signals to one or both of the first vibration actuator and the second vibration actuator. The vibrational signals are configured to cause the housing of the game controller to vibrate in a vibrational pattern during use of the controller. The vibrational pattern is one of a plurality of vibrational patterns, and one or more of the plurality of vibration patterns are activated in correlation to one or more game actions occurring during gameplay of a video game using the game controller.

A computer-based method and system for teaching educational sketching includes receiving a user-generated image created in response to a learning assignment and comparing the user-generated image to a solution image to identify one or more errors in the user-generated image relative to the solution image, where the errors may include additional image elements and missing image elements. Comparing is performed by providing a solution region corresponding to an acceptable variation from the solution image and identifying one or more errors based on a presence or absence of at least a portion of a corresponding element of the user-generated image within the solution region. If errors are identified and a non-passing status is determined, a hint is displayed to the user. The hint may be the correct elements of the user-generated image, a portion of the solution image, or a combination thereof.

Method for freehand sketch training

In a computer implemented sketch-based education or training system, guidance elements are generated and output to users both on an affirmative request of the user and in an automated manner without a request for guidance from the user. Automated guidance may take the form of a mini-hint that does not provide explicit information about a solution. The automatically provided guidance elements may contain numerical measures of correspondence between a user submitted sketch and a model sketch.

The disclosure relates to integrated modules for Synchronized Array of Vibration Actuators (FIG.A). The modules provide physical interface, power and communication interfaces. Each module may include vibration actuators (FIG.A) which can be precisely attached and aligned to the module housing, a microcontroller or other microprocessor, and one or more sensors for closed loop control of actuators (FIG.G). Interleaved pairs of ERMs having a center of mass in the same plane eliminate parasitic torque. A single module can produce a vibration force that rotates at a specific frequency and magnitude, which on its own could cancel out some types of periodic vibrations (FIG.B). Two modules paired together and counter-rotating with respect to each other can produce a directional vibration at a specific frequency and magnitude, which could prove even more useful for canceling out a vibration. Such modules are also employed to produce beating patterns (FIGS.-). Both amplitude and frequency of the beating force are variable.

The adjustable airway mannequin with visual feedback models the human skull, maxilla, upper teeth, lower teeth, jaw, spine and airway mounted on a backboard. Adjustments can be made to the height of the maxilla, the height of the upper teeth, the tension and distance of the jaw movement representing mouth opening, the anterior-posterior displacement of the jaw relative to the maxilla and skull, the presence or absence of the upper teeth and lower teeth, the range of motion of the spine, and tension on the airway to mimic a variety of anatomies. The mannequin may include one or more electronic proximity and position sensors that operate through magnetic field sensing, accelerometry, and optical sensing to monitor one or more of face length, jaw length, mouth opening, jaw tension, larynx position, head height off the table, and spine mobility.

Systems and methods disclosed stimulate nerve growth by applying a tensile (axial pulling) load on a proximal stump of the nerve. This load may be imposed once, at the time of repair. This implementation may be advantageously employed to remove tension away from the repair site, for any number of soft tissues, e.g., nerves, ligaments, tendons, and so on. Alternately, for a larger gap, by progressively elongating a nerve through tensile stimulation, the nerve may regenerate and be fully functional, particularly if elongated at a proper rate. After sufficient regrowth, nerve ends may be reattached, resulting in more complete functional recovery. Two implementations, which have been embodied in prototype devices, also include particularly useful features, one of which uses a screw and clamp with slotted insert design, and the other of which enables the use of sutures or straps to secure the tissue to the clamp.

The disclosure relates to a Synchronized Array of Vibration Actuators in a Network Topology providing synchronized arrays of low-cost, readily available vibration actuators to emulate superlative single actuators and bring together sets of these emulated high-performance actuators to create a broad range of desired control effects. Such actuator arrays may operate in both spatial and temporal modes, creating haptic effects that relate to the user via their position and orientation in space. The spatial mode may create h-pulses or the amplitude of a vibrational effect may change based on position of the device. The temporal mode may create vibrational effects that interact with the user to create an awareness of time. Additionally modes include performance, bandwidth, magnitude and reliability modes. The different control modalities may be combined together into a single vector control space, which spans the haptic capabilities of sets and/or subsets of actuators.

The disclosure relates to General Synchronized Vibration devices that provide haptic feedback to a user and improve the performance of existing vibratory devices. Different actuator types may be employed to provide synchronized vibration, including linear rotary actuators, rotating eccentric mass actuators including interleaved rotating mass actuators, and rocking mass actuators. A controller sends signals to one or more driver circuits to provide adjustment of vibration magnitude, frequency, and direction of the actuators. The system may apply forces onto an object, and a sensor measures a feature(s) of the object. This information is provided to a vibration device controller, which can then modify the vibration waveform to improve overall system performance. Fourier synthesis can be used to approximate arbitrarily shaped waveforms by controlling the phase and frequency of vibration actuators. These waveforms can include asymmetry where the peak force in one direction is higher than the peak force in another direction.

Asymmetric and general vibration waveforms from multiple synchronized vibration actuators

The present invention relates to synchronized vibration devices that can provide haptic feedback to a user. A wide variety of actuator types may be employed to provide synchronized vibration, including linear actuators, rotary actuators, rotating eccentric mass actuators, and rocking mass actuators. A controller may send signals to one or more driver circuits for directing operation of the actuators. The controller may provide direction and amplitude control, vibration control, and frequency control to direct the haptic experience. Parameters such as frequency, phase, amplitude, duration, and direction can be programmed or input as different patterns suitable for use in gaming, virtual reality and real-world situations.
