Publication number: 20240086142Abstract: Systems and methods are provided for dynamically adjusting a personal boundary of an avatar in an XR environment. The system identifies a first avatar in an extended reality (XR) environment based on rule data stored in a storage. In response to the system detecting that the first avatar has entered a portion of the XR environment at a communicable distance from a second avatar, the system does the following steps. The system determines an offensiveness rating of the first avatar. The system retrieves, from the storage, an offensiveness tolerance of the second avatar. The system compares the offensiveness rating of the first avatar and offensiveness tolerance of the second avatar. In response to determining, based on the comparing, that the offensiveness rating of the first avatar exceeds the offensiveness tolerance of the second avatar, the system automatically censors one or more messages from the first avatar to the second avatar.Type: ApplicationFiled: September 9, 2022Publication date: March 14, 2024Inventors: Gyanveer Singh, Dhananjay Lal, Reda Harb, Kyle Beckemeyer

Publication number: 20220270295Abstract: Automated techniques provide for recalibrating cameras in a real space in which puts and takes of items are tracked. The method includes first processing one or more selected images selected from a plurality of sequences of images received from a plurality of cameras calibrated using a set of calibration images that were used to calibrate the cameras previously. The first processing includes a process step to match one or more features from the selected images with features extracted from the set of calibration images using a trained neural network classifier. The features correspond to points located at displays or structures that remain substantially immobile. Camera calibrations can be updated when transform information between features matched meets or exceeds a threshold.Type: ApplicationFiled: May 10, 2022Publication date: August 25, 2022Applicant: STANDARD COGNITION, CORP.Inventors: Nagasrikanth KALLAKURI, Tushar DADLANI, Dhananjay SINGH, Daniel L.
