Coherent phase switching and modulation of a linear actuator array

Aspects of the technology employ synchronized arrays of low-cost, readily available vibration actuators to emulate and outperform single actuator systems, bringing together sets of actuators to create desired control effects. This approach involves coherent phase switching and modulation of a linear actuator array. A pair of linear resonant actuators (LRAs) may be employed for improved haptic waveform synthesis performance. According to one feature, energy may stored in the mechanical inertia of the LRA via velocity and stiffness of the LRA via displacement and released through modulation of the relative phase of the LRAs. Phase switching and modulation techniques may be used to control more than two LRAs, and in other arrangements than a dual LRA, including, but not limited to architectures that have LRAs arranged in multiple directions in an array spanning, for example, the two dimensions of a plane, or three dimensions of physical space.

Range of motion control in XR applications on information handling systems

More realistic experiences can be provided to a user through the use of a wearable suit. The xR wearable suit may include materials with adjustable characteristics, such as friction, and electronics for controlling the materials to provide feedback to the user wearing the xR suit. In an xR game, the materials may be used to translate virtual damage to physical constraints on the user. For example, when an avatar gets shot in the leg and is debilitated, the user's leg motion can be constricted to understand that shortcoming and stay in sync with the avatar. Examples of such feedback materials include inflating ribs, sheet jamming, and mechanical devices.

Haptic effect encoding and rendering system

The embodiments of the present invention enable novel methods, non-transitory mediums, and systems for encoding and generating haptic effects. According to the various embodiments, a media object is retrieved. The media object is analyzed to determine one or more time periods for rendering haptic effects. The haptic effects for rendering during the time periods are determined. The haptic effects are encoded as a haptic effect pattern that identifies a start time and duration for each of the haptic effects.
