Protosampling: Enabling Free-Form Convergence of Sampling and Prototyping through Canvas-Driven Visual AI Generation

As an emergent process, creativity relies on explorations via sampling and prototyping for problem construction. These activities compile knowledge, provide a context enveloping the solution, and answer questions. With Generative AI, practitioners can go beyond sampling existing media towards instantly generating and…

PrevizWhiz: Combining Rough 3D Scenes and 2D Video to Guide Generative Video Previsualization

In pre-production, filmmakers and 3D animation experts must rapidly prototype ideas to explore a film's possibilities before full-scale production, yet conventional approaches involve trade-offs in efficiency and expressiveness. Hand-drawn storyboards often lack spatial precision needed for complex cinematography, wh…

Generative Rotoscoping: A First-Person Autobiographical Exploration on Generative Video-to-Video Practices

This paper contributes a first-person exploration on AI video-to-video technologies, which I call "Generative Rotoscoping". This includes: insights on the creation process, a set of prototype explorations, and an integrated workflow for multi-modal video generation. Generative video is rapidly evolving and delivering…

Paratrouper: Exploratory Creation of Character Cast Visuals Using Generative AI

Great characters are critical to the success of many forms of media, such as comics, games, and films. Designing visually compelling casts of characters requires significant skill and consideration, and there is a lack of specialized tools to support this endeavor. We investigate how AI-driven image-generation techniq…

TimeTunnel: Integrating Spatial and Temporal Motion Editing for Character Animation in Virtual Reality

Editing character motion in Virtual Reality is challenging as it requires working with both spatial and temporal data using controls with multiple degrees of freedom. The spatial and temporal controls are separated, making it difficult to adjust poses over time and predict the effects across adjacent frames. To addres…

Immersive Sampling: Exploring Sampling for Future Creative Practices in Media-Rich, Immersive Spaces

Creative practitioners rely on sampling to understand, explore, and construct problems; or gather resources for later use. Despite practitioners' ability to experience immersive environments, sampling from them remains limited to primarily visual captures (e.g., screenshots, videos), which overlook the richness and va…

Escapement: A Tool for Interactive Prototyping with Video via Sensor-Mediated Abstraction of Time

We present Escapement, a video prototyping tool that introduces a powerful new concept for prototyping screen-based interfaces by flexibly mapping sensor values to dynamic playback control of videos. This recasts the time dimension of video mock-ups as sensor-mediated interaction. This abstraction of time as inter…

"I don't want to feel like I'm working in a 1960s factory": The Practitioner Perspective on Creativity Support Tool Adoption

With the rapid development of creativity support tools, creative practitioners (e.g., designers, artists, architects) have to constantly explore and adopt new tools into their practice. While HCI research has focused on developing novel creativity support tools, little is known about creative practitioner's values whe…

AirConstellations: In-Air Device Formations for Cross-Device Interaction via Multiple Spatially-Aware Armatures

AirConstellations supports a unique semi-fixed style of cross-device interactions via multiple self-spatially-aware armatures to which users can easily attach (or detach) tablets and other devices. In particular, AirConstellations affords highly flexible and dynamic device formations where the users can bring multiple…
