The present study aims to develop and validate an evidence-based functional balance task library for Augmented Reality-Functional Integrated Training (AR-FIT), incorporating standardized real-object integration through expert consensus and pilot usability testing. Furthermore, the study seeks to determine the effects of AR-FIT on balance and functional mobility in stroke survivors in comparison to conventional Augmented Reality \& task oriented training over an eight-week intervention period. In addition, it intends to evaluate participant motivation, engagement, and perceived task realism during AR-FIT using structured questionnaires and post-intervention interviews, thereby examining both clinical effectiveness and user-centered experience outcomes.
