Diffusion TV: Experiencing Diffusion Models through Tangible, Embodied Interaction
cs.HC · cs.AI
Quick verdict
CRT-TV installation maps antenna rotation onto diffusion denoising; evocative design, but embodied-XAI claims rest on informal, unevaluated observations.
Summary
Diffusion TV is an interactive AI art installation by Sihwa Park (York University) that repurposes a 1987 GoldStar CRT television as a tangible interface to diffusion-model generation. The antenna maps rotation to a continuous index over pre-extracted denoising stages, so audiences scrub between noise and a clear AI-generated image and sound of an animal; a VHF tuning knob switches among three channels — Past (extinct species), Present (endangered species), and Future (speculative creatures authored with ChatGPT o3) — framing the interaction within a temporal and ecological narrative. Images (Stable Diffusion XL) and audio (Stable Audio Open) were pre-generated for sixteen extinct and fourteen endangered species sourced from the IUCN Red List and WWF, plus twelve speculative future species; intermediate denoising steps were captured via Diffusers callbacks and served from Google Drive to a Processing client on a Raspberry Pi 5. The work was exhibited publicly at a Seoul design museum in May 2025. The author reports informal observations — the antenna interaction felt intuitive, older visitors navigated more easily while younger ones sometimes struggled — but evaluation is explicitly non-systematic, resting on observations and video recordings rather than audience studies. The core limitation is evidential: claims that embodied interaction constitutes an alternative mode of explainable AI are plausible but untested, and playback of pre-rendered denoising trajectories is not live generation.

Key claims under review
- Physical manipulation of a CRT TV antenna can metaphorically enact the denoising process of diffusion models, foregrounding generative process over final output (Sections 1–2).
- Intermediate denoising states can serve as primary experiential material for lay audiences rather than merely analytic artifacts for researchers (Sections 1–2).
- The installation offers an alternative, embodied mode of explainable AI that supports exploratory engagement and reflection without explicit technical explanation (Abstract, Section 6).
- Exhibition observations indicate the tuning metaphor supported intuitive engagement, with interaction fluency varying by visitors' prior CRT familiarity (Section 5).
Strengths
Coherent physical metaphor
Mapping antenna rotation to denoising stages exploits a genuine structural analogy (static↔noise, clarity↔signal); Figure 1's four-step display sequence (noisiest frame → intermediate → denoised with lower-third info → reset to next animal) makes the interaction legible without instruction.
Concrete, honest technical documentation
Sections 3–4 specify the hardware (GoldStar CMX-4200 13" 1987 CRT, Raspberry Pi 5, rotary + magnetic encoders, HDMI-to-RF modulator), models (SDXL, Stable Audio Open), pipeline (Diffusers per-step callbacks, Google Drive delivery, Processing client), and data provenance (IUCN Red List, WWF, ChatGPT o3).

Scope & Claims
Diffusion TV (Park, York University; XAIxArts 2026 workshop, 5 pages) is an installation paper: a 1987 GoldStar CMX-4200 CRT television is reconfigured so that antenna rotation selects among pre-extracted denoising stages of diffusion-generated media, while a VHF tuner knob switches Past/Present/Future channels (extinct, endangered, and ChatGPT o3-conceived speculative animals). Three claims structure the paper: (1) physical manipulation can metaphorically enact denoising, foregrounding process over output; (2) intermediate diffusion states can serve as primary experiential material; (3) the work constitutes an alternative, embodied mode of explainable AI (XAI) beyond screen-based GUI explanation. Claim 3 is the load-bearing one, and it is asserted rather than demonstrated.

Frequently asked questions
What is Diffusion TV?
Diffusion TV is an interactive AI art installation by Sihwa Park (York University), presented at the XAIxArts 2026 workshop. It modifies a 1987 GoldStar CRT television so that turning the antenna controls the clarity of AI-generated images and sounds, letting audiences physically act out the denoising process that diffusion models use to generate media.
Does Diffusion TV run diffusion models in real time?
No. Images (Stable Diffusion XL) and sounds (Stable Audio Open) were pre-generated in Google Colab; intermediate denoising steps were extracted with Diffusers callback functions and stored on Google Drive. A Processing client on a Raspberry Pi 5 only plays back the stored steps according to the antenna's position, so the interaction scrubs a pre-rendered trajectory rather than performing live inference.
What animals are featured in Diffusion TV?
Sixteen extinct and fourteen endangered species curated from the IUCN Red List and the World Wildlife Fund website (the Past and Present channels), plus twelve speculative future creatures whose names, histories, and generation prompts were invented with ChatGPT o3 (the Future channel).
Was the installation formally evaluated with visitors?
No. The paper's reflections come from the author's own observations and video recordings at a public exhibition in May 2025 (Hangaram Design Museum, Seoul). The author explicitly states that no structured empirical evaluation was conducted and plans systematic audience studies as future work.
About this review
This is an AI-generated preliminary review by Evolve.Pub, produced from the openly available text of the paper. It is not peer review and does not represent the authors' views. The canonical record of the paper is at the publisher link above.
- Figures 1–3 (display sequence, schematic diagram, installation photo) are referenced in the text but their visual content cannot be assessed from text extraction; judgments about the on-screen sequence and setup rely on the prose alone.
- The linked video documentation (sihwapark.com/Diffusion-TV) was not consulted; Section 5 assessments rest on the paper's own description of the recordings.
