  • Methods and systems to increase accuracy of eye tracking
    Patent number: 11295476
    Abstract: Systems and methods to monitor and interact with users viewing screens are disclosed. An example system includes a sensor to gather gaze data from a user viewing images on a display. The display has spatial coordinates. The system includes a processor communicatively coupled to the display and the sensor. The processor determines a first gaze location having first spatial coordinates based on the gaze data and calibration settings associated with determining gaze locations. The processor alters a portion of the display at or near the first gaze location. After the portion of the display has been altered, the processor determines a second gaze location having second spatial coordinates based on the gaze data and the calibration settings. The processor performs a comparison of the first gaze location to the second gaze location.

  • Methods and apparatus to monitor shoppers in a retail environment
    Patent number: 9288268
    Abstract: Methods and apparatus to monitor shoppers in a retail environment are disclosed herein. In a disclosed example method, a first signal is transmitted via a first device in a first direction to a second device and a second signal is transmitted via the first device in a second direction to a third device associated with a shopper. A direction of travel of the third device is determined based on the first signal and a path of travel of the third device through a monitored establishment is determined based on the second signal.
