Abstract
Systems and methods are disclosed for evaluating human eye tracking. One method includes receiving data representing the location of and/or information tracked by an individual's eye or eyes before, during, or after the individual performs a task; identifying a temporal phase or a biomechanical phase of the task performed by the individual; identifying a visual cue in the identified temporal phase or biomechanical phase; and scoring the tracking of the individual's eye or eyes by comparing the data to the visual cue.
Core Innovation
The invention evaluates human eye movement by receiving data representing a location where an individual's eye or eyes are looking before, during, or after the individual performs a task involving movement of the individual relative to a physical environment. The evaluation includes analysis of the received eye or eyes location data relative to a visual cue defined for where the individual should be looking during the task, and the visual cue is associated with the individual or an object during a biomechanical phase of the individual.
A visual cue location is identified based on performance of the task by one or more other individuals, and the invention generates a score of a location where the individual's eye or eyes are looking relative to the location of the visual cue during the biomechanical phase. The invention then generates an electronic display for informing the individual of the location of the visual cue and recommending training for the individual to perform based on the location of the visual cue.
The invention further updates the evaluation by receiving data representing a location where the individual's eye or eyes are looking for second or subsequent iterations of the task. The score is updated or a new score is generated based on locations where the individual's eye or eyes are looking relative to the location of the visual cue during biomechanical phases involved in the second or subsequent iterations of the task.
Claims Coverage
Independent claims are directed to a computer-implemented method, a system with data storage and processor instructions, and a non-transitory computer-readable medium. The inventive focus is on using visual cues derived from other individuals to score gaze relative to cue locations during biomechanical phases, and providing an electronic display with training recommendations that are updated across task iterations.
Gaze location receipt and cue-based scoring during biomechanical phases
Receiving data representing a location where an individual's eye or eyes are looking before, during, or after the individual performs a task involving movement relative to a physical environment; identifying a visual cue of where the individual should be looking during the task, associated with the individual or an object during a biomechanical phase and identified based on performance by one or more other individuals; and generating a score of a location where the individual's eye or eyes are looking relative to the location of the visual cue during the biomechanical phase, based on analysis of the received data relative to the visual cue.
Electronic display with cue location and training recommendation
Generating an electronic display for informing the individual of the location of the visual cue and recommending training for the individual to perform based on the location of the visual cue.
Iterative reassessment using second or subsequent task iterations
Receiving data representing a location where the individual's eye or eyes are looking before, during, or after the individual performs second or subsequent iterations of the task, and updating the score or generating a new score based on locations where the individual's eye or eyes are looking relative to the location of the visual cue during biomechanical phases involved in the second or subsequent iterations of the task.
Computer system including stored instructions for cue-based eye movement evaluation
A system comprising a data storage device storing instructions for evaluating human eye movement and a processor configured to execute the instructions to perform a method including receiving gaze-location data, identifying a visual cue based on performance by one or more other individuals, generating a score of gaze location relative to the visual cue during a biomechanical phase, generating an electronic display informing the individual of the visual cue location and recommending training, receiving gaze-location data for second or subsequent iterations, and updating or generating a new score based on the second or subsequent iteration gaze locations.
Non-transitory computer-readable medium for cue-based eye evaluation
A non-transitory computer readable medium storing instructions that, when executed by a computer, cause the computer to perform a method including receiving gaze-location data before/during/after task performance, identifying a visual cue based on performance by one or more other individuals, generating a score of gaze location relative to the visual cue during a biomechanical phase, generating an electronic display informing the individual of the visual cue location and recommending training, receiving gaze-location data for second or subsequent iterations, and updating the score or generating a new score based on the second or subsequent iteration gaze locations.
Across the independent claims, the inventive coverage centers on cue-based scoring of where an individual's eyes are looking relative to a visual cue identified from other individuals' task performance, during biomechanical phases of a movement task, with an electronic display that informs the individual of the cue location and recommends training, and with scoring updated using second or subsequent iterations of the task.
