15 schematically shows elements for performing a dementia diagnosis test and diagnosing whether or not dementia occurs according to an embodiment of the present invention.

Figure 15 (a) shows factors to be considered in determining whether to perform the dementia diagnostic test. As shown in (a) of FIG. 15 , in the test determination step ( S1000 ), it is possible to determine whether to perform the dementia diagnosis test based on the concentration score according to the content execution, the user's aging information, and the disease information. Specifically, among a plurality of users who have performed virtual reality, users with low concentration during content execution, users corresponding to the elderly, and users suffering from dementia may be selected and requested to perform a dementia diagnosis test. As a result, the system of the present invention can exhibit the effect of preventing dementia and early diagnosis by continuously performing a cognitive ability test for a user with a high risk of dementia or suffering from dementia.

Figure 15 (b) shows the factors for diagnosing the onset of dementia based on the result of the dementia diagnosis test and calculating the dementia grade. As shown in Fig. 15 (b), in the dementia diagnosis step (S1300), based on the correct rate and execution time of the dementia diagnosis test performed by the user, diagnosis is made on whether or not dementia occurs, and the dementia grade subdivided into 1 or more grades can be derived

Specifically, when performing a dementia diagnosis test, a user with reduced cognitive ability is highly likely to have a lower correct answer rate and take a long time to perform the test. Therefore, it is preferable to give a high dementia grade to the user who has shown the performance result as described above, and the dementia grade is expressed as a numerical value so that the user can easily recognize information about his or her health condition.
