Joytokey Aim — Assist

This paper quantifies the performance differential between native mouse/keyboard (MnK), native controller, and a JoyToKey configuration that routes controller input through mouse emulation while retaining the game’s aim-assist mechanics.

JoyToKey acts as a de facto aim-assist multiplier, allowing players to exploit game-specific assist values while using a more precise input modality. This creates a previously undocumented category of “soft cheating” – not detectable by anti-cheat software (since no memory manipulation occurs) but violating the intended input parity.

"Virtual Stick, Digital Bullet: An Empirical Analysis of Input Remapping, Latent Aim Assist, and Competitive Fairness in JoyToKey-Mediated First-Person Shooters" Author(s) & Affiliation Dr. A. Res, Department of Game Studies, University of Digital Interaction Prof. C. Heater, Human-Computer Interaction Lab, Tech Ethics Institute Abstract Background: The software utility JoyToKey allows players to map controller inputs (joysticks, buttons) to keyboard and mouse commands. In first-person shooter (FPS) games that natively support controllers, this creates a unique hybrid: the player uses a physical joystick for gross movement but benefits from software-emulated mouse aiming. Crucially, some games apply rotational aim assist (slowdown and magnetism) only when a controller is detected. By using JoyToKey to "trick" the game into thinking a mouse is a controller (or vice versa), players can potentially decouple the disadvantages of a joystick (imprecision) from the benefits of aim assist.
