Canvas3D: Empowering Precise Spatial Control for Image Generation with Constraints from a 3D Virtual Canvas

Generative AI (GenAI) has significantly advanced the ease and flexibility of image creation. However, it remains a challenge to precisely control spatial compositions, including object arrangement and scene conditions. To bridge this gap, we propose Canvas3D, an interactive system leveraging a 3D engine to enable prec…

JustShape: Exploring Co-Speech Gestures for Multimodal LLM-Powered 3D Parametric Modeling

Parametric modeling is a prevailing 3D modeling approach in design, architecture, and engineering. The emergence of multimodal large language models (LLMs) brings a new opportunity to lower the entry barriers to this powerful tool. However, describing 3D geometries through natural language can be fuzzy and challengi…

ARify: Leveraging Narrated Instructional Videos to Create Augmented Reality Tutorials for Procedural Tasks

Augmented Reality (AR) tutorials enhance procedural task learning by providing situated, step-by-step guidance. Yet, creating such tutorials requires AR authoring expertise, posing a significant entry barrier. To lower this barrier, we introduce ARify, an authoring system that semi-automatically transforms narrated in…

agentAR: Creating Augmented Reality Applications with Tool-Augmented LLM-based Autonomous Agents

Creating Augmented Reality (AR) applications requires expertise in both design and implementation, posing significant barriers to entry for non-expert users. While existing methods reduce some of this burden, they often fall short in flexibility or usability for complex or varied use cases. To address this, we introdu…

GesPrompt: Leveraging Co-Speech Gestures to Augment LLM-Based Interaction in Virtual Reality

Large Language Model (LLM)-based copilots have shown great potential in Extended Reality (XR) applications. However, the user faces challenges when describing the 3D environments to the copilots due to the complexity of conveying spatial-temporal information through text or speech alone. To address this, we introduce…

DesignFromX:Empowering Consumer-Driven Design Space Exploration through Feature Composition of Referenced Products

Industrial products are designed to satisfy the needs of consumers. The rise of generative artificial intelligence (GenAI) enables consumers to easily modify a product by prompting a generative model, opening up opportunities to incorporate consumers in exploring the product design space. However, consumers often st…
