Publication number: 20080055241Abstract: Systems and methods for haptic feedback effects for control knobs are described. One method comprises the steps of receiving a sensor signal associated with a motion of a manipulandum in a degree of freedom, and determining a direction of the motion of the manipulandum in the degree of freedom based on the sensor signal. The method further comprises outputting a first force signal if the determination indicates that the manipulandum moves in a first direction in the degree of freedom, and outputting a second force signal if the determination indicates that the manipulandum moves in a second direction in the degree of freedom.Type: ApplicationFiled: October 29, 2007Publication date: March 6, 2008Applicant: Immersion CorporationInventors: Alex Goldenberg, Steven Vassallo, Kenneth Martin, Adam Braun

Publication number: 20070285216Abstract: Method and apparatus for providing tactile sensations. For one embodiment a first frequency at which to output a tactile sensation is received. A second frequency higher than the first frequency is determined. The second frequency is based on a frequency at which an inertial actuator outputs a second tactile sensation. A waveform having the first frequency and a waveform having the second frequency is combined to produce a signal configured to cause a composite tactile sensation at the second frequency, the composite tactile sensation conveying the first frequency.Type: ApplicationFiled: April 16, 2007Publication date: December 13, 2007Inventors: Kollin Tierling, Adam Braun, Alex Goldenberg

Publication number: 20070272011Abstract: A universal athleticism rating system and related athletic performance measuring systems for accurately detecting and recording athletic performance are disclosed. The athleticism rating system evaluates individual athletes against a common, standardized, set of athletic performance tests. Each athlete performs the athletic tests and his or her scores in the individual tests are entered into a standardized calculation to produce a single athletic performance score. The related performance measuring system is preferably a timing system that ensures quick, easy, and accurate collection of athletic event timing related data without the need for the athlete to wear any special detection devices or the like. In a preferred embodiment, the performance measuring system integrates with the rating system to provide seamless athletic data collection and rating of athletes.Type: ApplicationFiled: November 7, 2005Publication date: November 29, 2007Inventors: Rodolfo Chapa, Hamid Arjomand, Adam Braun

Publication number: 20070152988Abstract: The present invention provides a control knob on a device that allows a user to control functions of the device. In one embodiment, the knob is rotatable in a rotary degree of freedom and moveable in at least one transverse direction approximately perpendicular to the axis. An actuator is coupled to the knob to output a force in the rotary degree of freedom about the axis, thus providing force feedback. In a different embodiment, the knob is provided with force feedback in a rotary degree of freedom about an axis and is also moveable in a linear degree of freedom approximately parallel to the axis, allowing the knob to be pushed and/or pulled by the user. The device controlled by the knob can be a variety of types of devices, such as an audio device, video device, etc. The device can also include a display providing an image updated in response to manipulation of the knob.Type: ApplicationFiled: November 21, 2006Publication date: July 5, 2007Inventors: Michael Levin, Kenneth Martin, Bruce Schena, Adam Braun, Louis Rosenberg

Publication number: 20060007184Abstract: A method and apparatus for controlling and providing force feedback using an interface device manipulated by a user. A microprocessor is provided local to the interface device and reads sensor data from sensors that describes the position and/or other information about a user object moved by the user, such as a joystick. The microprocessor controls actuators to provide forces on the user object and provides the sensor data to a host computer that is coupled to the interface device. The host computer sends high level host commands to the local microprocessor, and the microprocessor independently implements a local reflex process based on the high level command to provide force values to the actuators using sensor data and other parameters. A provided host command protocol includes a variety of different types of host commands and associated command parameters.Type: ApplicationFiled: September 15, 2005Publication date: January 12, 2006Inventors: Louis Rosenberg, Adam Braun, Mike Levin

Publication number: 20050088408Abstract: Method and apparatus for compensating for position slip in interface devices that may occur between a manipulandum and a sensor of the device due to a mechanical transmission. A device position delta is determined from a sensed position of a manipulandum of an interface device. It is determined if position slip has occurred caused by a change in position of the manipulandum that was not sensed by a sensor of the interface device, typically caused by a mechanical transmission between sensor and manipulandum. If position slip has occurred, an error in the sensed position caused by the position slip is corrected by adjusting the sensed position to take into account the position slip. The adjusted position delta is used as the position of the manipulandum and the display of objects controlled by the interface device are accordingly compensated.Type: ApplicationFiled: November 23, 2004Publication date: April 28, 2005Inventors: Adam Braun, Kollin Tierling, Kenneth Martin, Bruce Schena

Publication number: 20050057509Abstract: An interface device and method for providing enhanced cursor control with force feedback. A force feedback interface device includes a manipulandum, such as a mouse, that is moveable in a local workspace. The device is coupled to a host computer that displays a cursor in a graphical environment, such as a GUI, on a display screen. An interior region and a border region in the local workspace is defined. One mapping of device movement to cursor movement is used for the interior region, and a different mapping is used for the border region. Mapping methods include ballistics, absolute, linear, rate control, and variable absolute. Rate control embodiments can be single axis or dual axis. In one embodiment, when the mouse moves from the interior region to the border region, the mapping providing the greater cursor velocity is used to better conserve device workspace in the direction of travel and to decrease any sense of mapping mode change to the user.Type: ApplicationFiled: September 28, 2004Publication date: March 17, 2005Inventors: Jeffrey Mallett, Dean Chang, Louis Rosenberg, Adam Braun, Kenneth Martin, Jonathan Beamer

Publication number: 20050052415Abstract: Directional haptic feedback provided in a haptic feedback interface device. An interface device includes at least two actuator assemblies, which each include a moving inertial mass. A single control signal provided to the actuator assemblies at different magnitudes provides directional inertial sensations felt by the user. A greater magnitude waveform can be applied to one actuator to provide a sensation having a direction approximately corresponding to a position of that actuator in the housing. In another embodiment, the actuator assemblies each include a rotary inertial mass and the control signals have different duty cycles to provide directional sensations. For power-consumption efficiency, the control signals can be interlaced or pulsed at a different frequency and duty cycle to reduce average power requirements.Type: ApplicationFiled: July 8, 2004Publication date: March 10, 2005Inventors: Adam Braun, Louis Rosenberg, David Moore, Kenneth Martin, Alex Goldenberg
