The system and method for rendering tactile interaction using an ultrasound transducer array accurately represents dynamic interactions produced in a virtual environment with a varying pressure or force field.

A method is presented for providing haptic feedback through a touch-sensitive input device configured to provide input to a touch-sensitive computing device. The method comprises determining a haptic perception factor based on a set of computing device inputs received from sensors of the touch-sensitive computing device, the computing device inputs including at least a posture of the touch-sensitive computing device. A haptic response profile is determined based on the haptic perception factor. Haptic devices of the touch-sensitive input device are actuated based on the determined haptic response profile. Responsive to determining a change in the haptic perception factor based on a change in the posture of the touch-sensitive computing device the haptic response profile is then adjusted based on the changed haptic perception factor. The haptic devices of the touch-sensitive input device are then actuated based on the adjusted haptic response profile.

In aspects, zoned haptic effects are provided by assigning a plurality of zones corresponding to each of a plurality of zone actuators for providing haptic effects. A desired haptic response is provided for zones selected for actuation, and the response by the zone actuators is detected. Adjacent and non-adjacent zones are assigned for the detected zones as being driven by any of the plurality of zone actuators. Vibration on the adjacent and non-adjacent zone is suppressed in accordance with control parameters associated with the respective adjacent and non-adjacent zones. If a duration of the provided haptic effect has not passed, the suppression of vibration in the adjacent and non-adjacent zones is maintained and if the duration has passed, the suppression of vibration is terminated. Numerous other aspects are provided.

A computer-implemented method of displaying a user interface comprises: displaying a preview of a message on a screen; receiving a discard motion; displaying a discard instruction with varying opacity during the receiving, the opacity increasing in proportion to a range of the discard motion; reaching a minimum motion threshold; and discarding the message.

A recoil mount for a virtual reality tracker comprising a resonator that is situated in between a one or more dampers, the one or more dampers each including a strut that is coupled to opposing sides of the resonator, a tracker interface coupled to the resonator, the tracker interface adaptable with a virtual reality tracker, and a pair of fasteners that mount the one or more dampers to a weapon mounting surface.

Systems and methods for generating pseudo haptic feedback for a virtual widget are disclosed. The method includes computing, from a force profile of the virtual widget, a virtual displacement value based on a force value and a type of the virtual widget. The force profile describes a user's perception of physical characteristics of the virtual widget. The method generates a visual haptic feedback based on the virtual displacement value and the type of the virtual widget. Further, in response to the force value, the method may display on a display screen the visual haptic feedback.

An electronic device, while displaying representations of a plurality of collections of media items, detects a swipe input that starts at a location corresponding to a first representation of a first collection of media items in the plurality of collections of media items. In response to detecting the swipe input: in accordance with a determination that the swipe input is in a first direction, the device scrolls the representations of the plurality of collections of media items in the first direction; and, in accordance with a determination that the swipe input is in a different, second direction, the device: ceases to display a representation of a first item in the first collection of media items, and displays a representation of a second item in the first collection of media items, without scrolling; and generates a tactile output corresponding to displaying the representation of the second item.

The present technology relates to an information processing device, an information processing method, a server device, and a program capable of presenting haptic information by using an existing data format.

A smartphone includes a data processing unit configured to supply a haptic control signal to a haptic presentation device on the basis of haptic control information embedded in image data in a predetermined file format. The present technology is applicable to, for example, a terminal device or the like including a display that displays an image and allows a user to perform a touch operation.
