Title: Innovations of Ari Pitkänen
Introduction
Ari Pitkänen is a notable inventor based in Vantaa, Finland. He has made significant contributions to the field of eye-tracking technology, holding a total of five patents. His work focuses on enhancing the accuracy and functionality of eye-tracking systems, which have applications in various industries.
Latest Patents
One of his latest patents is titled "Light field based eye tracking." This innovative eye-tracking system includes light-sensing units, each equipped with at least three light sensors and a converging lens. The system is designed to collect sensor data from individual light sensors, which indicates the respective light intensities of the signals sensed. It determines the direction from which light signals are incident upon the light-sensing unit, based on differences in light intensities. Additionally, it calculates the orientation of the user's eye relative to the light-sensing unit and determines the gaze direction based on this orientation and the position of the light-sensing unit.
Another significant patent is a "Calibration arrangement, method for calibrating light intensity reading and a system for determining gaze direction." This arrangement includes a first light emitter that emits light and a first light receiver that generates an output signal. The controller provides control signals to the light emitter to emit light pulses during specified periods, measures the output signals, and calculates differences to calibrate the light intensity reading effectively.
