Patent attributes
A method is provided, comprising: sensing color intensity values of light emitted from a portion of a display screen for a predefined period of time, the display screen being configured to display a video stream that defines the light emitted from the portion of the display screen, the video stream being generated by an executing video game; during the period of time, triggering a controller device to communicate an input event to the video game, the video game being configured to process the input event and responsively update the video stream to change a color of the light, from a first color to a second color; analyzing the sensed color intensity values to identify a latency amount that is defined by a duration of time extending from the triggering of the controller device to the change in the color of the light emitted from the portion of the display screen.
