This study aims to investigate the effect of computerized vestibular function assessment and interactive training system, combined with cognitive/motor dual-task for the elderly with dizziness. The investigators will compare the movement abilities among older adults with different cognitive level, and further establish an assessment module that can evaluate participants' dual-task performance in both vestibular and cognitive tasks. Finally, leveraging the advantages of sensor detection technology and computerized feedback, an appropriate dual-task rehabilitation approach for vestibular function and cognition will be developed.
