A virtual reality (VR) system includes a light source configured to illuminate an area and a plurality of photosensors configured to receive reflections from the illuminated area. The system includes a trained orientation module configured to store a trained neural network model and a gaze direction identification module coupled to the light source and the plurality of photosensors. The gaze direction identification module includes a light reflection module configured to receive a light intensity value from each of the plurality of photosensors and an eye coordinate determination module configured to apply the trained neural network model to the light intensity value from each of the plurality of photosensors to determine a horizontal coordinate value and a vertical coordinate value. The system includes a display configured to adjust a displayed image based on the gaze position of the illuminated area.
