The Genesis is an item used by the characters of Resident Evil: Revelations, a game where Jill Valentine is the main playable character. The Genesis is used to find resources (such as ammo or healing items) in the environment.
The animation of the hero art shows a first person view of the Genesis, this is exactly how it looks in Resident Evil: Revelations when the player is trying to scan the environment. The sound effects are also taken from the same game.
