FOCUS. Recently, the development of techniques to capture and process wireless stray electromagnetic (EM) radiation from different radio sources is gaining increasing attention. RF sensing is, for example, an emerging paradigm that transforms existing wireless networks by adding sensing modalities to improve the perception of users and the environment. Stray fields of wireless devices in arbitrary frequency bands are recorded in a phase-sensitive manner and visualized in 3D to reconstruct or map the surrounding environment. These techniques can be generally exploited to transform radio networks into virtual radio sensors to allow mapping of objects, human-scale sensing, behavior recognition, and crowd density estimation. Ubiquitous perception through RF signals is a pivotal opportunity for future technology: it enables personalized services such as smart living, automated logistics or interaction through free-space gestures. However, it also challenges ethical and moral boundaries and threatens privacy. The workshop encourages authors from academia and industry to submit manuscripts on innovations on radio sensing, holography, networks, and computing techniques for privacy-selective human scale sensing. Analysis of social implications of the technology are also welcomed.

MAIN TOPICS

• Radio-based vision, radar and holographic methods, image processing, distributed machine learning, federated learning

• Electromagnetics (EM), physics-driven body models in high frequency bands

• Smart reconfigurable antenna, beamforming and beam steering for RF sensing

• Sustainable, privacy and ethically compliant RF sensing based on federated learning tools

• Data fusion and multi-domain techniques to improve the robustness of RF sensing

• Applications in workplaces, assisted living, Industry 5.0, location-based services

• Public awareness and social interaction studies, privacy threats and ethical designs

• Biases in data representations, decision-making, impact of dataset limitations and demographic exclusions

• Strategies for ensuring fairness and equitable access in RF sensing applications

AIM 

The proposed workshop aims to collect different experiences in the field of RF-sensing to define the current and future role of this technology and immediately define its advantages and critical issues considering its current and future role. The workshop will also explore challenges and opportunities of ethics-by-design in RF sensing, examining design models, technical and ethics measures, their potential role in future regulatory efforts.

WORKSHOP FORMAT

Solicited papers must report significant and innovative research and development results that will have a long-term impact on the field of research, with the potential for implementation. The final manuscripts must comply with the formatting requirements for UBICOMP-ISWC 2025. We will accept two types of submission: long and short papers. A long paper should have a length of maximum 6 pages and short paper maximum 4 pages. Short papers can showcase early implementations, prototypes, work-in-progress systems.

Workshop in Espoo, Finland .......................................... October 12-13

Submission

Papers should be submitted using the UbiComp ISWC 2025 proceedings format: https://ubicomp.org/ubicomp-iswc-2025/authors/formatting/. All submissions are made through the Precision Conference System (Society: SIGCHI → Conference Ubicomp/ISWC 2025 → Track: Ubicomp/ISWC 2025 workshop HOLDEN). Submitted papers will be reviewed and judged on originality, technical correctness, relevance, and quality of presentation. The accepted papers will appear in the UbiComp supplemental proceedings and in the ACM Digital Library. The final manuscript must be accompanied by a registration fee payment proof and it is mandatory that at least one author attends and presents the paper. Failure to adhere to these guidelines may result in paper exclusion from post-conference distribution. For any detail regarding registration to the Workshop, please refer to the Call for Workshops as well as the UbiComp-ISWC 2025 website.
