Rapid Prototyping with VideoClipper: In-camera Storyboarding and Video Capture

Title of the Paper

VideoClipper: Rapid Prototyping with the “Editing-in-the-Camera” Method

Paper Information

• Domain: Human-Computer Interaction (HCI) and User Experience Design (UX Design)
• Keywords: Interaction design, participatory design, rapid prototyping, video production, storyboard, video brainstorming, video prototyping

Research Background and Problem

• Problem or Challenge: Current video prototyping tools focus heavily on complex post-production editing, making it difficult to quickly capture the dynamic details of user interaction design. Designers often avoid video tools due to their time-consuming and labor-intensive nature.
• Significance: User interaction design requires dynamic demonstrations of user-system interactions rather than relying solely on static visual materials. Video tools can help designers express and explore interaction details through video.
• Research Motivation and Related Work:
  • Video has significant value in prototyping, but existing video production tools and methods are too cumbersome for early-stage rapid prototyping.
  • Related work includes rapid prototyping methods (e.g., "Wizard of Oz" technique), video prototyping, and video brainstorming, but there is still a lack of tools to support rapid video generation in early design stages.

Solution

• Method or Solution: The study proposes the “Editing-in-the-Camera” method and supporting tools, VideoClipper and Collaborative VideoClipper.
  • “Editing-in-the-Camera” Method: Uses title cards to guide video shooting, avoiding post-production editing and enabling real-time video creation with greater immediacy and usability.
  • VideoClipper: Supports single-user tablet-based design, offering title cards, interactive storyboards, and simple effects (e.g., ghosting and stop-motion animation).
  • Collaborative VideoClipper: Supports remote collaborative design, allowing multiple users to simultaneously edit and create video content across different devices.
• Innovations:
  • Combines video capture with title card-based interactive storyboards.
  • Introduces a “ghosting” feature for easily creating seamless stop-motion animation effects.
  • Addresses challenges in remote collaboration for video capture with Collaborative VideoClipper.
• Implementation Steps and Technical Highlights:
  • Define a sequence of title cards to guide video shooting.
  • Use VideoClipper or Collaborative VideoClipper to convert title cards into interactive video storyboards.
  • Adjust shooting sequences in real-time during video capture and use simple editing features to finalize the prototype video.
  • Collaborative VideoClipper leverages Webstrates and Videostrates to support real-time remote collaboration and video playback.

Research Outcomes

• Specific Outcomes:
  • Designed and implemented two tools (VideoClipper and Collaborative VideoClipper).
  • Validated the tools’ effectiveness and applicability through various teaching courses and design activities.
  • Developed a new method that significantly reduces the time required for video capture and editing in design processes.
• Advantages:
  • Simplifies workflows in video prototyping, encouraging immediate design exploration and iteration.
  • Provides lightweight video capture tools suitable for early design stages, enabling simultaneous shooting and discussion.
  • Collaborative VideoClipper achieves real-time synchronization across multiple devices and users.
• Experimental or Evaluation Results:
  • Using VideoClipper reduced video shooting time by 34% and editing time by 38% compared to traditional tools.
  • Highly positive feedback from students on the tool’s ease of use and special effects (e.g., “ghosting”).
  • Effectively applied in scenarios such as video brainstorming, video prototyping, interviews, and participatory design.
• Limitations and Future Directions:
  • Collaborative VideoClipper may encounter network performance issues when uploading videos simultaneously.
  • The current tool does not support branching storyboards (used to showcase alternative interactions or design options).
  • Future work could expand tool functionality, such as enhancing asynchronous collaboration support and optimizing cross-platform performance.

Conclusion

The “Editing-in-the-Camera” method and the developed VideoClipper tools provide interaction designers with an effective solution to the complexity of video prototyping, significantly reducing the workload of video shooting and editing while enhancing collaboration in design activities. This research not only introduces new possibilities for rapid prototyping in early design stages but also offers valuable insights for tool design and methodological studies.
