Mouse dynamics analysis has traditionally focused on linguistic tasks—such as recognizing users based on how they type or move the mouse during text entry. This paper argues that focusing solely on linguistic tasks limits the application of mouse dynamics in broader computer vision and human-computer interaction (HCI) scenarios. The authors introduce N0LMT (Non-Linguistic Mouse Tracking), a large-scale dataset designed to capture mouse movements during non-linguistic tasks, such as object selection, dragging, and free-form movement. The paper establishes baseline benchmarks for user identification and verification using state-of-the-art deep learning architectures.

Mouse dynamics serve as a behavioral biometric. Previous datasets (like the Balabit Mouse Dynamics dataset) often involved users performing general computer tasks or filling out forms (linguistic context). The authors identify a gap: The Goal: Create a dataset that isolates mouse
The Goal: Create a dataset that isolates mouse motor control from the cognitive load of linguistic processing to understand pure motor behavior. such as object selection
