The component according to claim 5, wherein the real-time parameter of the environment of the user relates to the features of the light received by the user, said features comprising at least one of the temporal features, the spatial features, the spectral features, and the intensity of the light.
The component according to claim 5 or 6, wherein the real-time parameter of the environment of the user relates to one or more of: temperature, the noise of the environment of the user, and the time of the day.
The component according to any of the preceding claims, wherein the computer executable instructions further comprise instructions for: - receiving life habits data and/or health profile data relating to at least one parameter of the life habits of the user and/or to at least one parameter of the health profile of the user, and - adjusting the migraine risk based on the life habits data and/or on the health profile data.
The component according to claim 8, wherein the parameter of the life habits of the user relates to one or more of: the food habits of the user, the physical activity habits of the user, the sleeping habits of the user, and the rhythm of life of the user, and wherein the parameter of the health profile of the user relates to one or more of: the professional situation of the user, the personal situation of the user, the general state of health of the user, the gender of the user, the age of the user, and the ongoing migraine treatment of the user.
The component according to claim 9, wherein the parameter of migraine history is determined with measurements and/or with answers of the user to questionnaires.
A real-time visual behavior measuring device (20) comprising the user migraine analysis component 10, according to any of the preceding claims, being embedded into the device and at least one sensor configured to measure in real time at least one visual behavior parameter indicative of the visual behavior of the user and a communication unit (38) configured to communicate the measured real time visual behavior parameter to a user migraine analysis component.
The real-time visual behavior measuring device according to claim 11, wherein the real-time visual behavior measuring device (20) is a head mounted device arranged to be mounted on the head of the user.

Description

FIELD OF THE INVENTION The invention relates to a user migraine analysis component and to a real-time visual behavior measuring device. The invention further relates to a system for determining the migraine risk for a user. BACKGROUND OF THE INVENTION Migraines affect around 15% of the worldwide population. Half of migraine sufferers do not consult a physician when they feel impaired. Thus, determining the risk of migraines for a user may be useful in many situations. For example, some activities require a great degree of concentration. It is useful to be able to provide an indication of the migraine risk to the user carrying out such activity, or to a third party. Indeed, it has been observed that a change in behavior upon carrying out an activity may lead to very different results in terms of achievement of the activity. Typically, when a person is driving it can be very useful to analyze the risk and the severity of migraine of the person so as to provide an alert when the risk or severity for a migraine is greater than a threshold value and driving represents a risk. Therefore, there is a need for a device and a method for accurately determining the risk or the severity of migraine of a person. One object of the present invention is to provide such a device. WO2006/017153 discloses an apparatus for determining migraine triggers. SUMMARY OF THE INVENTION The invention is defined in the appended claims. It is disclosed a user migraine analysis component, comprising: a memory configured to store computer executable instructions; anda processor for executing the computer executable instructions, wherein the computer executable instructions comprise instructions for: receiving at least one visual behavior parameter indicative of the real time visual behavior of the user, anddetermining the migraine risk of the user based on the analysis of the at least one visual behavior parameter. In particular, the memory may also be configured to store parameters. Advantageously, determining the migraine risk of the user based on the analysis of at least one visual behavior parameter of the user provides a highly accurate estimate of the risk or the severity of migraine of the user. Indeed, the inventors have observed that the real time visual behavior of a person may be linked very precisely and accurately to the migraine risk of the user. According to embodiments which can be considered alone or in any combination: the visual behavior parameter relates at least to the eyelids activity of the user; and/orthe computer executable instructions further comprise instructions for: receiving real-time physiological data relating to at least one real time parameter of the physiology of the user, anddetermining the migraine risk considering the real-time physiological data; and/orthe real-time parameter of the physiology of the user relates to sweating of the user and/or the pulse of the user and/or the temperature of the user and/or the breathing rhythm of the user and/or muscle spasm of the user; and/orthe computer executable instructions further comprise instructions for: receiving real-time environment data relating to at least one real-time parameter of the environment of the user, anddetermining the migraine risk considering the real-time environment data; and/orthe real-time parameter of the environment of the user relates to the features of the light received by the user, said features comprising at least one of the temporal features, the spatial features, the spectral features, and the intensity of the light; and/orthe real-time parameter of the environment of the user relates to temperature and/or the noise of the environment of the user and/or the time of the day; and/orthe computer executable instructions further comprise instructions for: receiving life habits data and/or health profile data relating to at least one parameter of the life habits of the user and/or to at least one parameter of the health profile of the user, andadjusting the migraine risk based on the life habits data and/or on the health profile data; and/orthe parameter of the life habits of the user relates to the food habits of the user and/or the physical activity habits of the user and/or the rhythm of life of the user, and the parameter of the health profile of the user relates to the professional situation of the user and/or the personal situation of the user and/or the general state of health of the user and/or the gender of the user and/or the age of the user and/or the ongoing migraine treatment of the user; and/orthe computer executable instructions further comprise instructions for: ∘ providing at least one migraine history parameter indicative of the migraine history of the user, and∘ adjusting the migraine risk based on at least one migraine history parameter; and/orthe parameter of migraine history is determined with measurements and/or with answers of the user to questionnaires. The invention relates to a real-time visual behavior mea
