In a nystagmus test under an infrared camera, nystagmus images are not only observed on monitors but also stored in video devices, etc. When they are saved as video images, it is very important to find a way to record the information of the head positions on the video.We developed a videonystagmography system with head-position recording embedded in it: a USB infrared camera and a motion sensor device are attached to a pair of goggles made by a 3D printer and then the goggles are connected to a computer with a USB cable: the data generated by the sensor create head animation which is correlated with the nystagmus images using the software that we developed.Herein we report on the system in our clinic which is much lighter in weight and significantly more portable than the existing head-position recording system produced by medical equipment manufacturers because no power supply is required if it is used with a portable computer.
