1. A method of adjusting an interface between a user and a sensorized device, the method comprising:
receiving at least a first substantially real-time pupillometric data value from the user from at least a first time point and at least a first substantially real-time unconstrained environmental data value from at least one location proximal to the user from the first time point;
receiving at least a second substantially real-time pupillometric data value from the user from at least a second time point and at least a second substantially real-time unconstrained environmental data value from at least one location proximal to the user from the second time point, wherein the user is using the sensorized device at least proximal to the first time point and/or the second time point;
isolating one or more cognitive load factors from one or more non-cognitive load factors influencing the user at the first and second time points based at least upon the first substantially real-time pupillometric data value, the first substantially real-time unconstrained environmental data value, the second substantially real-time pupillometric data value, and/or the second substantially real-time unconstrained environmental data value to determine a cognitive load change in the user between the first and second time points to produce a determined cognitive load change, wherein determining the cognitive load change in the user between the first and second time points comprises determining an inverse probability of the cognitive load change given the first substantially real-time pupillometric data value, the first substantially real-time unconstrained environmental data value, the second substantially real-time pupillometric data value, and/or the second substantially real-time unconstrained environmental data value; and,
adjusting at least one function of the sensorized device at least proximal to the first time point and/or the second time point based at least in part on the determined cognitive load change in the user, thereby adjusting the interface between the user and the sensorized device.
