URDANETA, Camilo; RODRIGUEZ-ALMANZA, Julián  and  CORTES-RICO, Laura. SensorMov, Native Library for Tangible Interactions with Android Devices. TecnoL. [online]. 2023, vol.26, n.56, e207.  Epub Mar 29, 2023. ISSN 0123-7799.  https://doi.org/10.22430/22565337.2446.

The study presented in this paper aimed to contribute to the Spanish-speaking mobile developer community with a set of free programming tools, documentation, and examples to create tangible user interfaces with smartphones. These interfaces allow diversifying interactions with mobiles, prioritizing alternative uses of their sensors. The development of this set of tools occurred within the framework of a research project that sought to promote the dialogue of knowledge between engineering and traditional textile knowledge. The project used a participatory design methodology that involved diverse actors in different stages: self-recognition and mutual recognition, ideation, prototyping, and experimentation. As a result, we present a review of references on mobile devices and tangible interfaces, highlighting those mobile interactions that use physical objects and gestural actions; a technical description of SensorMov: its architecture and the specific design and, finally, its preliminary evaluation through a case study and an academic project. The library understands the tangible as the mobile itself or passive physical objects that do not require electrical power, such as magnets. In this sense, the documented version of SensorMov allowed working with raw data from the sensors, identifying objects and positions according to the static magnetic field of physical objects, and identifying and positioning physical objects on the mobile screen. The main challenge for the future is to enable appropriation spaces that facilitate and extend the library's use and functionalities, creating a community around it.
