TalkSketch: Multimodal Generative AI for Real-time Sketch Ideation with Speech
Abstract
Sketching is a widely used medium for generating and exploring early-stage design concepts. While generative AI (GenAI) chatbots are increasingly used for idea generation, designers often struggle to craft effective prompts and find it difficult to express evolving visual concepts through text alone. In the formative study (N=6), we examined how designers use GenAI during ideation, revealing that text-based prompting disrupts creative flow. To address these issues, we developed TalkSketch, an embedded multimodal AI sketching system that integrates freehand drawing with real-time speech input. TalkSketch aims to support a more fluid ideation process through capturing verbal descriptions during sketching and generating context-aware AI responses. Our work highlights the potential of GenAI tools to engage the design process itself rather than focusing on output.

Research summary
The main contribution of this paper is the development of TalkSketch, a multimodal AI system that integrates speech and sketching to enhance the creative ideation process for designers. This work represents a significant step towards more intuitive and fluid interactions with generative AI, although it requires further validation and exploration of its broader implications.
Methodology
The methodology employed in TalkSketch is innovative in its integration of multimodal inputs—speech and sketching—aimed at enhancing the ideation process for designers. The formative study conducted with designers provides a solid foundation for understanding user needs and informs the design of the system. However, the paper could benefit from a more detailed description of the underlying algorithms and models used for speech recognition and sketch interpretation, as well as how these components interact in real-time.
Results & evaluation
The experimental evaluation is somewhat limited due to the small sample size (N=6) in the formative study. While qualitative insights are valuable, a larger-scale quantitative evaluation would strengthen the findings. The paper does not provide detailed metrics or benchmarks to assess the performance of TalkSketch, which limits the ability to gauge its effectiveness compared to existing solutions.
Reproducibility
The paper lacks sufficient implementation details, such as specific algorithms, datasets used for training, and the architecture of the multimodal system. This absence of information makes it challenging for other researchers to reproduce the results or build upon the work. Including a GitHub repository or detailed supplementary materials would enhance reproducibility.
Limitations
One significant limitation is the small sample size in the formative study, which may not represent the broader population of designers. Additionally, the paper does not address potential challenges in real-time processing, such as latency in speech recognition or sketch rendering, which could impact user experience. Furthermore, the reliance on specific user demographics in the study may limit the generalizability of the findings.
Broader impact
The potential applications of TalkSketch extend beyond design ideation, potentially influencing fields such as education, art, and collaborative brainstorming. By facilitating a more natural interaction between users and AI, it could enhance creativity and innovation in various domains. However, ethical considerations regarding AI's role in creative processes should be addressed to ensure responsible use. The main contribution of this paper is the development of TalkSketch, a multimodal AI system that integrates speech and sketching to enhance the creative ideation process for designers. This work represents a significant step towards more intuitive and fluid interactions with generative AI, although it requires further validation and exploration of its broader implications.
