The feedback mining system may include a token-handling subsystem that enables token-based transactions with respect to the collaborative evaluations generated by the feedback mining system, including token reward transactions in exchange for contributing data (e.g., feedback data) used to generate the collaborative evaluations and token redemption transactions in exchange for requesting the collaborative evaluations.

Abstract: Various embodiments provide an asset management distributed ledger system for capturing, storing, and providing access to asset information/data. For example, the distributed ledger system may capture and store asset information/data that provides a complete record of an asset and further provide access to the asset information/data via an IUI or search function of the distributed ledger system. The distributed ledger system may include a token-handling subsystem that enables token-based transactions with respect to the distributed ledger and/or implemented via the distributed ledger. A token value (e.g., units of digital currency) may be distributed to users as rewards for making contributions to the distributed ledger and may be redeemed by users as costs associated with accessing the asset information of the distributed ledger.

Abstract: In one embodiment, a computing device may determine a virtual content to be displayed with a scene of a real-world environment. The device may generate an image depicting the virtual content. Using one or more sensors, the device may detect characteristics of the scene of the real-world environment.

Abstract: A method may include displaying, to a user, a first color in a first area and a second color in a second area, where (1) the second color has a longer wavelength than the first color and (2) the first and second color have an expected longitudinal chromatic aberration for a human eye. The method may also include receiving, from the user, an indication of whether the user perceives (1) the first area as being clearer than the second area or (2) the second area as being clearer than the first area. The method may further include determining, based on the indication of the user and the expected longitudinal chromatic aberration, information about a refractive error of the user's vision.

Abstract: Systems, methods, and computer readable medium are provided for automatically resetting a zero-offset calibration coefficient for a pressure transducer. Ambient pressure measurements from a first pressure sensor and a second pressure sensor can be received by a computing device and compared. Based on determining a difference in the received ambient pressure measurements, an updated zero-offset calibration coefficient can be generated. The updated zero-offset calibration coefficient can be transmitted to the first pressure sensor, which once received, causes the first pressure sensor to update a previously determined zero-offset calibration coefficient with the updated zero-offset calibration coefficient.

Abstract: A multiplanar head mounted display (HMD) includes two or more artificial display planes for each eye located at optical distances that can be dynamically adjusted based on a location within a scene presented by the HMD that the user views. For example, a scene is presented on two or more electronic display elements (e.g., screens) of the HMD. A focal length of an optics block that directs image light from the electronic display elements towards the eyes of a user is adjusted using a varifocal system (e.g., an element that mechanically changes a distance between a lens system in the optics block and the electronic display element, an element that changes shape of one or more lenses in the lens system in the optics block, etc.) based on a location or object within the scene where the user is looking.

Abstract: A near-eye display (NED) has an orientation detection device and a display block. The orientation detection device collects orientation data that describe an orientation of the NED. The display block has a display assembly, a focusing assembly, and a controller. The controller determines an orientation vector of the NED based in part on the orientation data and computes an angular difference between the orientation vector of the NED and a gravity vector. After comparing the angular difference to a threshold value, the controller generates multifocal instructions that adjusts the optical element to display an augmented scene at the selected image plane corresponding to the multifocal instructions.
