VisualEyes is a device that football quarterbacks wear on their arms to receive an animation of the play sent to them by the head coach during the game.


Currently today, communication between the coach and players on the field is mediated by unidirectional broadcasts from the coach to the quarterback and one designated defensive player, as well as hand signals from the coach to other players. This method of communication is error prone, especially in loud stadiums or when trying to run plays very quickly. Additionally, for competitive reasons the link is turned off 15 seconds before the start of each play so the coach cannot provide play-specific coaching as the QB walks to the line.

Our product would improve on all of these factors by providing a robust, reliable system that nevertheless does not provide too much of a competitive advantage as to be unfair or jeopardizing the integrity of the game.

Competitive Analysis

  • Id Coach: Allows the coach to send a play in from a custom device to a wristband. Our product will be better because the wristband is bulky and the UI for this product is terrible.
  • DigitalPlaybooks: This product is just a tablet app that helps coaches visualize plays. Our product actually sends the plays in to the players.
