  • Publication number: 20200028843
    Abstract: A method for authenticating a user is presented. Responsive to a request for access to a computer resource, a computer system prompts the user making the request to access the computer resource to perform a new motion in an environment in which the user is monitored by a sensor system. Detected biometric data in the new motion performed by the user is identified by the computer system. A determination is made as to whether the user performing the new motion is an authenticated user based on comparing the detected biometric data with stored biometric data for a prior motion performed by the authenticated user. The computer system provides access to the computer resource when the user is identified as the authenticated user.

  • Patent number: 10524737
    Abstract: Techniques that facilitate condition detection in a virtual reality system and/or an augmented reality system are provided. In one example, a system includes a virtual reality component and an anomaly detection component. The virtual reality component collects motion data and biometric data from a virtual reality device. The motion data is indicative of motion information associated with one or more accelerometer sensors of the virtual reality device. The biometric data is indicative of biometric information associated with one or more biometric sensors of the virtual reality device. The anomaly detection component integrates the motion data and the biometric data into a machine learning model to generate anomaly detection data for the virtual reality device.

  • Publication number: 20200004326
    Abstract: Augmented reality speed reading is provided by detecting a reader's changing gaze direction; detecting movements of the reader's eye; and between movements of the reader's eye, displaying text at the reader's gaze direction. An exemplary apparatus includes an eye illuminator that delivers light to a reader's eye; an eyeward camera that generates digital images of the reader's eye including reflected light from the eye illuminator; a display; and a processor that is connected in communication with the eyeward camera and the display. The processor implements an eye tracking module that receives the digital images from the eyeward camera and detects the reader's gaze direction, and the processor implements a text display module that controls the display to present text at the reader's gaze direction.

  • Publication number: 20190188259
    Abstract: A method, system, and/or computer program product for identifying and replacing a deficient component in a product. One or more processors deconstruct a text product review into multiple n-grams, where each of the multiple n-grams is a review of a particular component from components of a product. The processor(s) generate a component numeric rating value (CNRV) for each of the multiple n-grams, where the CNRV is based on an analysis of each of the multiple n-grams. The processor(s) identify a deficient component of the product. The processor(s) identify a cause of the deficiency in the deficient component and identify a replacement component that does not cause the deficiency in the deficient component. The processor(s) direct a manufacturing device that manufactures the product to replace the deficient component with the replacement component.

  • Patent number: 10268677
    Abstract: One or more processors deconstruct, by utilizing natural language processing (NLP), a text product review into multiple n-grams, where each of the multiple n-grams is a sequence of words from the text product review, and where each of the multiple n-grams is a review of a particular component from the multiple components of the product. The processor(s) generate a component numeric rating value (CNRV) for each of the multiple n-grams using machine learning techniques such as collaborative filtering, and store CNRVs for the multiple components of the product together with identifiers of particular components of the product. The processor(s) receive a request for a particular CNRV for the particular component of the product, retrieve the particular CNRV, and then transmit the particular CNRV to a requesting device of the request in order to adjust an operational feature of the requesting device.

  • Publication number: 20190026438
    Abstract: According to an embodiment of the present invention, a system analyzes a collection of medical documents to identify within document content risk factors of medical conditions associated with corresponding activities. A processor in the system maps the identified risk factors of the activities to one or more medical tests for the associated medical conditions, and analyzes a medical record and social media communications of a patient to determine participation of the patient in one or more of the corresponding activities. The processor determines the one or more medical tests to conduct from the mapping based on the risk factors associated with the determined activities of the patient. Embodiments of the present invention further include a method and computer program product for analyzing patient activity to conduct appropriate medical tests in substantially the same manner described above.
