Abstract: A computing device may determine a haptic effect to be produced by a haptic device of the computing device. The computing device may select, based at least in part on the haptic effect, a modulation frequency. The computing device may determine a combination of a carrier frequency and the modulation frequency to produce the haptic effect. The computing device may drive the haptic device according to the combination of the carrier frequency and the modulation frequency to output a vibration pattern associated with the haptic effect.

Abstract: The combination of active and reference haptics on an electronic device, such as a wearable display device, can convey information to a user without requiring the user to look at the device. An electronic device may include a housing, a display disposed in the housing and including an interface surface arranged for user contact and a reference haptic. The interface surface includes an active haptic output that provides a time-dependent haptic output and a reference haptic disposed on the housing or the interface surface to provide a time-independent haptic output related to the time-dependent haptic output.

Abstract: Disclosed herein are techniques and systems for providing simulated, haptic feedback that is local to physical, non-actuating keys of a keyboard. A keyboard includes a plurality of non-actuating keys defined in a cover portion of the keyboard, a plurality of force-producing mechanisms coupled to a substrate underneath and adjacent the cover portion. The force-producing mechanisms may be positioned on suspended portions of the substrate that are mechanically isolated and arranged on the substrate to substantially correspond to a layout of the plurality of non-actuating keys. The force-producing mechanisms may be individually actuated to deflect the suspended portions of the substrate underneath the cover portion to create a tactile sensation for a user's finger that is local to a particular key. In some embodiments, the force-producing mechanisms are piezoelectric actuators.

Abstract: In a virtual or augmented reality system, a module with multiple contact points may provide haptic output associated with a virtual object being held or manipulated by a user's hand. A drone-like airborne device may keep such a module hovering close to the user and provide just-in-time contact and other types of haptic feedback when needed. The user experiences virtual objects with a head-mounted display and such a module that delivers multidimensional haptic feedback, including but not limited to, contact, surface stiffness, surface texture, and thermal properties of the virtual object that is in contact with the user's hand and fingers. The propellers on the drone device provide full six-degrees-of-freedom (6-DOF) force and torque feedback to the user via such a module attached to the airborne system. In some implementation, the user wears a wrist band that docks with such a module via magnets on both the wrist band and the module.

Abstract: Various technologies pertaining to provision of haptic feedback to users of computing devices with touch-sensitive displays are described. First haptic feedback is provided to assist a user in localizing a finger or thumb relative to a graphical object displayed on a touch-sensitive display, where no input data is provided to an application corresponding to the graphical object. A toggle command set forth by the user is subsequently identified; thereafter, an input gesture is received on the touch-sensitive display, and second haptic feedback is provided to aid the user in setting forth input data to the application.

Abstract: Techniques for providing adaptive timing support may reduce the cognitive load on a presenter during a presentation by tracking the pace of the presentation on behalf of the presenter. A time interval may be initially allocated to each of multiple sections of a presentation based on a target time duration for the presentation. The actual presentation time duration of a section may be monitored during coverage of the section. Following the detection of an advance to another section of the presentation, the allocated time interval established for each of one or more remaining sections in the presentation may be updated based on a time difference between the actual presentation time duration and the allocated time interval of the section.

Abstract: In some examples, an electronic device may provide haptic output associated with a gesture for performing a task using the electronic device. For instance, one or more sensors of the electronic device may detect movement of a touch input within an area of a display corresponding to an area of a graphical user interface. In response to detecting movement of the touch input, one or more haptic feedback components may generate haptic output associated with a task, such as an operating system task. In some implementations, the haptic output changes surface friction of an area of the display during movement of the touch input, providing feedback and guidance for the user to successfully complete the task.

Abstract: A body support structure such as a chair provides an input device for a computer or computer-controlled apparatus via sensors associated with the chair. The sensing chair sensor or sensors covering the seat and/or seat back. The sensing chair determines an occupant's position, movement, weight shifting, and/or other parameters regarding the occupant. In one form, the sensor is adapted to obtain pressure and pressure distribution of the occupant in the sensing chair, both static and real-time. The pressure and/or pressure distribution data/signals for the occupant is processed to provide control/control signals to a processing system, computer, and/or computer-controlled apparatus. The sensing chair provides novel opportunities for human-computer interaction, such as input for the automobile industry, the office industry, for interactive graphical user interfaces/displays, and for computer games and gaming systems.
