We prototyped "Interfacing device for image-based multi-sensor data acquisition" by embedding various complexed sensor information and intaking with visible information. In this study, we tried to improve the interfaces. We made the new device that realizing the sensor fusion via image. It is able to intake images with multi-sensor data and save time of synchronizing etc. Our device obtains sensor information as images by converting voltage signal to lightness of LED. We estimated each signal features which get through our device in the study.
