In-Situ Visual Programming

Authors: Ulrich Brandstätter and Bernhard Schenkenfelder

Published in: OASIcs, Volume 134, Companion Proceedings of the 9th International Conference on the Art, Science, and Engineering of Programming (Programming 2025)

Abstract
Most Visual Programming Environments (VPEs) available today aim to make software development more accessible for specific domains, such as automation, business intelligence, data science, education, or real-time media processing. In their niches, VPEs offer several advantages over traditional text-based programming, including shorter training times, immediate visual feedback, and lower barriers to entry. With this work, we introduce In-Situ Visual Programming (ISVP), a novel programming paradigm to enable users to create, modify, and contribute to software via visual programming in physical contexts. User-created and pre-built programs can be attached to and interlinked with physical objects - in an Augmented Reality (AR) environment. We believe that the spatial and contextual proximity of processing code and physical objects will make software development more intuitive, and we argue this position based on two model use cases.

Quantum Table: A Tangible Quantum Circuit Demonstrator

Authors: Stefan Hillmich, Raphael Zefferer, Mathias Gartner, Bernhard Schenkenfelder, Sonja Bruckner, and Ulrich Brandstätter

Published in: OASIcs, Volume 134, Companion Proceedings of the 9th International Conference on the Art, Science, and Engineering of Programming (Programming 2025)

Abstract
Quantum computing has considerable potential, but its abstract nature often intimidates beginners, and existing quantum circuit simulator interfaces can be overwhelming for them. To address this accessibility issue, we have developed an intuitive simulator that integrates the principles of a tangible, collaborative tabletop workbench with quantum circuits. This simulator allows users to manipulate circuits through physical interaction, providing real-time visual feedback. The use of tangible user interfaces (TUIs) in complex systems has been shown to improve the user experience by allowing users to control and represent data flows through physical objects. Inspired by the tangible workbench’s use of dynamic visual cues, our system employs similar techniques to help users understand quantum operations through direct manipulation and visual representation. The integration of tangible interaction with quantum circuit simulation is a novel approach to making quantum computing more accessible and engaging.
