Online Writing Recognition – Review: Trajectory-Based Modeling and Recognition of Characters and Words

Neurons in the brain's nerve system regulate handwriting, which reflects a person's psychology and personality. User authentication, the evaluation of neurodegenerative conditions, and the categorization of handedness, gender, and age groups are only a few of the uses for this special quality. Conventional authentication methods are susceptible to security breaches because they involve fingerprints, memorization, and information leaking.    Online handwriting is a contemporary human-computer interaction technique that allows users to write on the surface in an unconstrained, natural way. Due to its unique characteristics, pen-based online handwriting is far more challenging than typical 2D handwriting systems that rely on ink and paper.
