Embodiments of the invention are generally directed to systems, methods, and machine-readable mediums for implementing gesture-based signature authentication. In one embodiment, a system may include several modal input devices. Each modal input device is capable of retrieving a stream of modal input data from a user. The system also includes modal interpretation logic that can interpret each of the retrieved modal input data streams into a corresponding of set of actions. The system additionally includes modal pairing logic to assign each corresponding set of actions to control one of the displayed objects. Furthermore, the system has modal control logic which causes each displayed object to be controlled by its assigned set of actions.
