Description

FIELD OF THE INVENTION The invention relates to a method for customizing a mounted sensing device comprising a first set of similar or identical sensors having different location and/or orientation, each sensor being adapted to measure at least one first parameter relating to the wearer of the mounted sensing device. The invention further relates to a mounted sensing device. BACKGROUND OF THE INVENTION More and more mounted devices comprise sensors adapted to measure parameters relating to the wearer or the environment of the wearer. Such measured parameters may be used to adapt the mounted device. Increasing the accuracy of the measurements performed by such sensors is important to be able to use such measurements either to perform statistical studied or event generate accurate information concerning the wearer and/or the environment. A way of increasing the accuracy of the measurements is to improve the accuracy of the sensors them self. However, a specificity of having sensors mounted on a mounted sensing device is that the sensing conditions are unstable. The mounted sensing device may move relative to the user and the environment may change quickly and be very diverse. Therefore, even using very accurate sensors the overall measurements may not be very accurate in particular because of the specific measurements condition linked to the fact that the sensors are mounted on a mounted sensing device to be mounted on a wearer, for example on the head or wrist of the wearer. Thus there is a need for a method for increasing the accuracy of the measurements performed by sensors mounted on mounted sensing devices. Conventional methods are known in US 2014/118243 A1, US 2015/029088 A1, US 2014/160424 A1, US 2010/110368 A1 and US 8862715 B1. One object of the present invention is to provide such a method. SUMMARY OF THE INVENTION To this end, the invention is defined in the claims and proposes a method as defined in claim 1. Advantageously, providing a mounted sensing device with a plurality of similar or identical sensors having different locations and/or orientations and selecting the most appropriate sensor based on the location and/or orientation of the sensors allows increasing the accuracy of the measured parameter. Indeed, the inventors have observed that depending on the parameter to be measured and the wearer the position and/or orientation of the sensor may greatly influence the accuracy of the measured parameter. The invention proposes to provide a mounted sensing device, for example a head mounted sensing device, with a set of similar sensors and to customize such mounted sensing device by selecting the most appropriate sensor(s). Such solution appears more appropriate financially than trying for each wearer to determine the best position and/or orientation of the sensor(s) and providing a mounted sensing device with such customized sensors. Indeed, the method according to the invention allows customizing "universal" mounted sensing devices. Furthermore the method according to the invention allows adjusting in real time the most appropriate sensor(s) among the set of sensors. According to further embodiments which can be considered alone or in combination: the mounted sensing device is a head mounted device and/or a wrist mounted device; and/orduring the selecting step the at least one selected sensor is selected based on application data indicative of the application of the measured parameter; and/orduring the selecting step the at least one sensor is selected based on position data indicative to the position of the mounted sensing device relative to the wearer, for example the head of the wearer; and/orduring the selecting step a specific spatial distribution of sensors is selected; and/orthe mounted sensing device further comprises a second set of similar sensors having different location and/or orientation and being adapted to measure at least one second parameter relating to the wearer of the mounted sensing device, the second parameter being different than the first parameter, and during the selecting step at least one sensor from the second set of sensors is selected so that the location and/or orientation of the selected at least sensor is the most appropriate of the second set of sensors for the wearer and/or for measuring the at least one second parameter; and/orthe sensors comprise sensors, for example eye tracking sensors, arranged to measure the gazing direction or the wearer and/or the eyelid beat of the wearer and/or the pupil dilation of the wearer; and/orthe sensors comprise sensors, for example capacitive sensors, configured to measure the contact area or the distance between the mounted sensing device and the wearer, for example the wearer's head; and/orthe sensors comprise sensors, for example resistive sensors, configured to measure biological and/or physiological parameters of the wearer; and/orthe sensors comprise optical blood pressure or blood analysis sensor, for example hear
