Abstract
Methods are disclosed for determining an efficacy of a stimulus based on one or more measurable physiological responses to one or more stimuli including one or more stimulus features. Data is acquired on physiological responses of a group of one or more subjects to presentation of one or more stimuli including one or more stimulus features. The data on the one or more physiological responses of the one or more subjects is correlated with the presentation of the one or more stimulus features included in the one or more stimuli. The correlated data on the one or more physiological responses are associated with a separately-determined efficacy of the one or more stimuli to form a stimulus efficacy model. From this information, a projected efficacy of a stimulus is determinable by comparing one or more subsequently-measured physiological responses to the stimulus with the stimulus efficacy model.
Core Innovation
The invention determines an efficacy of one or more stimuli by providing a computing system comprising an output device and an input device operatively coupled to one or more sensors, and subjecting one or more subjects to one or more stimuli displayed on the output device. During stimulus presentation, the system acquires at least a first set of data associated with one or more stimulus features and a second set of data associated with physiological responses to the one or more stimuli including the one or more stimulus features.
The first set of data includes weighted, extracted stimulus feature data associated with the one or more stimulus features during presentation of the respective stimuli and captured as a function of time. The first set of data is weighted via a first filter comprising a temporal element, while the second set of data includes weighted, physiological response data and is weighted via a second filter comprising a spatial element.
The invention correlates the first and second sets of data after the respective weighting by the temporal element and the spatial element, and associates the correlated data with a separately-determined efficacy of the one or more stimuli to form a stimulus efficacy model. The invention determines a projected efficacy of a second stimulus by comparing one or more subsequently-measured physiological responses to the second stimulus with the stimulus efficacy model, thereby projecting efficacy using the model.
Claims Coverage
1 independent claim is covered. The inventive features include weighting stimulus feature data with a temporal filter, weighting physiological response data with a spatial filter, correlating the weighted datasets, forming a stimulus efficacy model from separately-determined efficacy, and projecting efficacy for a second stimulus by comparing subsequently measured physiological responses to the model.
Stimulus efficacy model from temporally filtered stimulus features and spatially filtered physiological responses
A computer-implemented method comprising providing a computing system with an output device and an input device operatively coupled to one or more sensors; subjecting one or more subjects to one or more stimuli displayed on the output device; acquiring a first set of data associated with one or more stimulus features and a second set of data associated with physiological responses measured via the one or more sensors; weighting the first set of data as weighted, extracted stimulus feature data with a first filter comprising a temporal element and weighting the second set of data as weighted, physiological response data with a second filter comprising a spatial element; correlating the first and second sets of data; and associating the correlated data with a separately-determined efficacy of the one or more stimuli to form a stimulus efficacy model.
Projected efficacy by comparing subsequently measured physiological responses to the stimulus efficacy model
Determining a projected efficacy of a second stimulus by comparing one or more subsequently-measured physiological response to the second stimulus with the stimulus efficacy model.
The independent claim ties together temporally filtered stimulus-feature data, spatially filtered physiological-response data, correlation to separately-determined stimulus efficacy to create a stimulus efficacy model, and projection of efficacy for a subsequently tested stimulus by comparison of newly measured physiological responses to the model.
