In one embodiment, the first timing sequence displays the letter E on the first display 01, the second timing sequence does not display the letter E on the second display 02, the letter E does not display the letter E on the first display 01, and the letter E is displayed in a reciprocating manner. The time of the first timing was 3 seconds, and the time of the second timing was 3 seconds, and the total timing time was 3 minutes. When the first display screen 01 and the second display screen 02 are displayed, the letter E is gradually reduced from the area accounting for 1/9 of the screen to the area accounting for 1/90 of the screen. During the display of the letter E, the user needs to press the corresponding E direction key on the handle to feed back the direction of the letter E (as shown in 301 in fig. 4), the feedback result is sent to the server, the server records the feedback result and compares the feedback result with the actual direction of the E, judges whether the direction of the E fed back by the user is consistent with the actual direction of the E, if so, records the correct times, and gives out the statistical result after the test is completed.
In one embodiment, the first timing sequence displays the letter E on the first display 01, and simultaneously displays the letter E on the second display 02, and the second timing sequence does not display either the first display 01 or the second display 02, and so on. The time of the first timing is 3 seconds, the time of the second timing is negligible, and the total timing time is 3 minutes. When the first display screen 01 and the second display screen 02 are displayed, the letter E is gradually reduced from the area accounting for 1/9 of the screen to the area accounting for 1/90 of the screen, and is reduced in ten levels. During the display period of the letter E, the user automatically judges whether the direction of the E displayed on the first display screen 01 is consistent with the direction of the E displayed on the second display screen 02, and according to the judging result, the user presses the ∈and ∈keys (shown as 302 in fig. 4) on the handle to feed back, the feedback result is sent to the server, the server records the feedback result, judges whether the judging result of the user is consistent with the actual result, if so, the user records the correct times, and gives out the statistical result after the test is completed.
In one embodiment, the first timing sequence displays the letter E on the first display 01, and simultaneously displays the letter E on the second display 02, and the second timing sequence does not display either the first display 01 or the second display 02, and so on. The time of the first timing is 3 seconds, the time of the second timing is negligible, and the total timing time is 3 minutes. When the first display screen 01 and the second display screen 02 are displayed, the letter E is gradually reduced from the area accounting for 1/9 of the screen to the area accounting for 1/90 of the screen, and is reduced in ten levels. During the display of letter E, the user needs to press the left turn key and the right turn key on the handle (302 shown in fig. 4) to adjust the direction of E on the first display screen 01 to be consistent with the direction of E on the second display screen 02, press the confirmation key after adjustment is completed (303 shown in fig. 4) to confirm feedback and send the feedback result to the server, the server records the feedback result, and judges whether the judgment result of the user is consistent with the actual result, if the judgment result is consistent with the actual result, the correct times are recorded, and the statistical result is given after the test is completed.
