This short paper presents a preliminary implementation of SensorMov, a native library for Android mobile devices, which provides development tools for creating tangible user interfaces connected to smartphones. SensorMov brings together a set of functionalities aimed at extending various mobile sensors through physical objects. We seek to diversify mobile phone use in interaction processes, inspiring mobile technologies' heterogeneity while reducing development times and complexities. The library understands tangibles as the smartphone itself or passive physical objects that do not require power supply through electrical energy, such as magnets. The paper describes the library, a preliminary application case, and future work.
