Abstract:
Methods, systems, and apparatus for generating sensations in response to haptic data. A sensation output device can include a processor adapted to generate one or more control signals corresponding to a haptic command, an actuator adapted to output a force to a drive mechanism in response to one or more control signals received from the processor, an opening through which a portion of a user's body can be inserted, and an interface surface coupled to the drive mechanism, the interface surface configured to at least partially contact the inserted portion of the user's body. Further, the interface surface can be a compliant belt having surface features that is coupled with a carrier belt that is in contact with the drive mechanism. Additionally, the sensation output device can include a memory storing an algorithm including one or more haptic commands, which can be executed by the processor.

Abstract:
An apparatus for interfacing an elongated flexible object with an electrical system. The apparatus includes an object receiving portion and a rotation transducer coupled to the object receiving portion adapted to determine the rotational motion of the elongated flexible object when the object is engaged with the object receiving portion and to provide an electromechanical interface between the object and the electrical system. In a preferred embodiment, the rotation transducer includes an actuator and translational transducer to provide a translational electromechanical interface between the object and the electrical system.
Abstract:
In an aspect, an electronic device includes a housing; a manipulandum positioned in the housing, wherein the manipulandum is moveable in at least one rotary degree of freedom in response to a user moving the manipulandum; a sensor coupled to the manipulandum, the sensor outputs sensor signals associated with the movement of the manipulandum in the at least one rotary degree of freedom by the user's direct contact; a processor coupled to the sensor and configured to output one or more activating signals based on the sensor signals; a first actuator coupled to the manipulandum, wherein the first actuator outputs a contact force to the manipulandum upon receiving a first activating signal; and a second actuator positioned within the housing and separate from the first actuator, wherein the second actuator outputs an inertial force to the housing upon receiving a second activating signal.
Abstract:
An apparatus comprises an actuator that includes an eccentric mass that is coupled to a rotatable shaft of the actuator which defines an axis of rotation. A circuit is coupled to the actuator, the circuit is configured to produce a control signal such that, when the control signal is received by the actuator. The actuator is configured to produce a force effect having a magnitude and a frequency by rotating the mass about the axis of rotation in a first direction. The magnitude of the vibration is based on a duty cycle of the control signal and independent of the frequency. An obstacle member is coupled to the actuator and includes a compliance portion configured to increase energy in the movement of the mass in a second direction opposite to the first direction when the mass comes into contact with the obstacle member.
Abstract:
A presence detection system comprising, among other things, a radio transmitter and receiver is described herein. The transmitter includes a motion detection circuit, a microprocessor, and a radio frequency modulator. The motion detection circuit is configured to direct a motion detected signal to the microprocessor upon the transmitter being moved in a predetermined manner. The microprocessor is configured to generate an encoded message that includes a preamble denoting a beginning of the encoded message, an identification code denoting a type of transmitter, and a check message (such as a checksum) containing information about content of the encoded message. Finally, the radio frequency modulator is configured to modulate the encoded message at a transmitting frequency.
Abstract:
A low-cost haptic feedback trackball device for providing haptic feedback to a user for enhancing interactions in a graphical environment provided by a computer. The trackball device includes a sensor device that detects the movement of a sphere in two rotary degrees of freedom. An actuator applies a force preferably along a z-axis perpendicular to the plane of the surface supporting the device, where the force is transmitted through the housing to the user. The output force is correlated with interaction of a controlled graphical object, such as a cursor, with other graphical objects in the displayed graphical environment. Preferably, at least one compliant element is provided between a portion of the housing contacted by the user and the support surface, where the compliant element amplifies the force output from the actuator by allowing the contacted portion of the housing to move with respect to the support surface. The force can be an inertial force, contact force, or a combination of forces that provide tactile sensations to the user.
