About

Alexandre Gomes de Siqueira is a researcher at the intersection of human-computer interaction, tangible computing, and educational technology. His work reimagines how novices engage with computational thinking by moving beyond traditional screen-based programming. In his highly cited paper "BlockXR: A Novel Tangible Block-Based Programming Platform" (2021, 4 citations), Siqueira introduced a pioneering approach that replaces purely graphical user interfaces with physical, tangible blocks. This innovation allows users to construct programs by manipulating real-world objects, bridging the gap between digital logic and physical interaction. By designing platforms that make programming more intuitive and accessible, Siqueira’s contributions directly support inclusive education and the development of computational literacy in young learners. His research demonstrates how tangible interfaces can lower barriers to entry, fostering engagement and deeper understanding. With a focus on creating embodied learning experiences, Siqueira continues to shape the future of block-based programming, inspiring new directions in both human-computer interaction and educational design.
