This review summarizes the research progress in virtual supermarket for the assessment and rehabilitation training of mild cognitive impairment (MCI).Patients with MCI often have impaired social function, especially in shopping. Virtual supermarket can be designed and constructed using virtual reality technology, allowing patients to simulate shopping-related tasks, and collecting diversified behavioral data with real-time feedback, which can assess the cognitive function of patients in multiple dimensions. Interactive tasks performed using the virtual supermarket can improve cognitive function of patients in multiple domains, such as memory, attention, visuospatial, and executive function. In the future, the assessment accuracy and scene design should be further optimized to make the virtual supermarket play a greater role.
