Overview Visual cues ,e.g. hand signals,  are a time-tested communication schemes that help humanity survive throughout the history. It provides a simple, quick, yet understandable common ground for communication. Light-emitting Diodes (LEDs) are  typical electronic elements to demonstrate a visual cue, such as indicating a device's ON or OFF states.
