  • Patent number: 12646356
    Abstract: Systems and methods for automated eye tracking assessment for skill development. In some examples, a system includes an eye tracking device; a third-person tracking system comprising at least one external camera; and a computer system comprising one or more processors. The computer system is configured for receiving, while a user is performing a task, eye gaze data from the eye tracking device, a user-view video from the user-view camera or screen capture technology, and, in some examples, an external video of the user from the external camera. The computer system is configured for determining whether or not the user's gaze is fixated on or tracking a specific location or object in a performance space for a threshold amount of time prior to the onset of a movement or a performance action. The computer system is configured for determining a task performance outcome.

  • Patent number: 12620458
    Abstract: A method for automated assessment of aseptic technique of compounding in a compounding hood includes collecting, using sensors positioned in or around a compounding hood, data from which positions, orientations, and movements of objects used in an aseptic compounding task can be determined. The method further includes feeding the data into an automated aseptic technique evaluator. The method further includes identifying, using the automated aseptic technique evaluator and from the data, phases of the aseptic compounding task. The method further includes automatically detecting, by the automated aseptic technique evaluator, errors occurring during at least some of the phases. The method further includes generating and displaying, by the automated aseptic technique evaluator, output indicative of the errors.
