Vision induced motion sickness detection method based on electrocardiogram signal gravity center frequency

Abstract

The invention discloses a vision induced motion sickness detection method based on electrocardiogram signal gravity center frequency. Two pairs of electrocardiogram signal sensors are arranged in left and right frontal lobe zones and left and right temporal lobe zones of a user, four channel electrocardiogram signals of the user at a normal stage and a detection stage are respectively acquired, different signals of the electrocardiogram signals of the left and right frontal lobe zones are calculated, alpha wave signals are extracted from the electrocardiogram signals, then the gravity center frequency sequences of the alpha wave signals are calculated according to preset time window parameters, the gravity center frequency average values of the alpha wave signals of the right frontal lobe zone and the right temporal lobe zone at the normal stage and at the detection stage and the gravity center frequency standard deviations of the alpha wave signals of the different signals of the electrocardiogram signals of the right frontal lobe zone, the left temporal lobe zone, the right temporal lobe zone and the left frontal lobe zone are calculated, the six pairs of signals serve as detection signals, it is determined that a vision induced motion sickness phenomenon occurs when the difference of the signals detected at the normal stage and the detection stage is larger, and accordingly vision induced motion sickness detection is achieved.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and more specifically relates to a detection method for visually induced motion sickness based on the center of gravity frequency of electroencephalogram signals. Background technique [0002] In recent years, 3D, virtual reality (Virtual Reality, VR) and other technologies have developed rapidly, and stereo display technology (stereo display technology) has ushered in a new development opportunity. It also has broad application prospects in clinical medicine, electronic maps, traffic management, and smart life. These developments are based on the main feature of stereoscopic display technology: the technology presents visual images in a three-dimensional stereoscopic form, which can give people a strong sense of three-dimensionality and immersion. However, many people experience visually induced motion sickness (VIMS) during stereoscopic viewing, which is a physical reaction induce...
