Abstract: The disclosure discloses a method and system for preventing motion sickness, the method includes: obtaining, by a processing circuit, a current motion state of a user; judging, by the processing circuit, whether a start condition of an electromagnetic pulse circuit is met according to the current motion state of the user; and triggering, by the processing circuit, the electromagnetic pulse circuit to generate a micro-current affecting an equalizing pulse of a human semicircular canal via a pulsed electromagnetic field, after determining that the start condition is met.

Abstract: The present disclosure relates to a testing method of a 3D display cross interference and the testing device thereof. The method according to the present disclosure comprises: acquiring a brightness of at least one first test image in a region where a left eye image is displayed in a display device and a brightness of at least one second test image in a region where a right eye image is displayed in the display device through a left eye lens or a right eye lens of stereo glasses; comparing the brightness of the acquired first test image and the brightness of the acquired second test image, and determining a cross interference value or a cross interference value range between the left eye image and the right eye image according to the comparison result, a grey scale value of the first test image and a grey scale value of the second test image.
