Abstract: A computer-implemented method and a computer program product for device pairing by cognitive computing. A cognitive computing system creates a knowledge corpus about the historical activities of pairing devices of a user. The cognitive computing system predicts needs of device pairing of the user, based on analysis of the historical activities. The cognitive computing system identifies devices that can be paired in a surrounding area. An augmented reality device tracks an eye direction of the user at a device, extrapolates the eye direction to create an eye focus direction of the user, obtains from the cognitive computing system an eye focus line with an arrow pointing to the device, and creates an augmented reality overlay which shows the eye focus line. The augmented reality device pairs a user currently used device and the device, upon user approval.

Abstract: A computer-implemented method, a computer program product, and a computer system for dynamically creating a composition reference video to support a user activity. In response to that a user selects a reference video for performing an activity, the computer system identifies a search query of a reference video. The computer system identifies personalized parameters of the user, based on a knowledge corpus user preferences of performing activities, and the search query. The computer system identifies appropriate videos and video transcripts in an online video repository and identifies textual contents through document and text search, based on a prediction about how the user is to perform the activity. The computer system draws series of images based on the textual contents. The computer system normalizes contents from the appropriate videos and the series of images and normalizes voices in the contents from the appropriate videos.

Abstract: A live event virtual experience is provided. Emotions of virtual spectators to a current situation occurring in a live event at a physical venue are determined from received data regarding reactions of the virtual spectators to the live event using bias detection. A historical sound clip that matches the emotions of the virtual spectators to the current situation occurring in the live event is retrieved. The historical sound clip that matches the emotions of the virtual spectators to the current situation occurring in the live event is input into a machine learning model that performs inverse bias mitigation to amplify bias and applies in-process adversarial fairness debiasing. The historical sound clip after performing the inverse bias mitigation to amplify the bias and applying the in-process adversarial fairness debiasing is converted to a standardized historical sound segment length. A sound representation is generated from the standardized historical sound segment length.

Abstract: A rollable, lightweight compact cushion that may be attached to an object of different dimensions using the adjustable attachment apparatus. The outer covering of the cushion has a pocket incorporated in the outer covering that provides the user a small storage space to store objects. A loop is attached in a predetermined position to allow the user to hang small objects from the loop. An elasticized loop allows the user to easily roll up and secure the cushion in a compact position for ease of transport and storage. The stuffing material for the cushion is a biodegradable natural rubber latex foam free of added fillers and/or petroleum products.
