Abstract: Generally discussed herein are devices, systems, and methods for calibration of a gaze indicator. A method can include receiving gaze tracker output data that indicates a gaze location on a display at which a user is gazing, determining an expected gaze location to which the user is expected to gaze after the gaze location, receiving further gaze tracker output data that indicates a subsequent gaze location on the display at which the user is gazing, and adjusting, based on the subsequent gaze location and the expected gaze location, a location of a visual gaze indicator on the display.

Abstract: A method of performing time series prediction by improper learning comprising calculating a plurality of filters based on a symmetric matrix and generating a mapping term based on a time series input and a function. The method may include comprising iteratively: transforming the function using the calculated plurality of filters; predicting an interim output using the transformed function and the mapping term; computing an error of the interim output based on a known output; and updating the mapping term based on the computed error. The method may include generating the mapping term through iterations over a predetermined interval and performing a time series prediction using the mapping term generated over the iterations.
