Visual Captions: Enhancing Remote Conversations with Real-Time Dynamic Imagery

As Seen On

The concept of augmenting verbal communication with visuals during remote video communication is gaining traction in this age of rapidly evolving technology. As impressive as current video communication tools are, they can sometimes fall short in conveying the full meaning of verbal exchanges. To address this challenge, researchers have developed a groundbreaking system called “Visual Captions” which uses live verbal cues to display relevant visuals in real-time.

Presented at the ACM CHI 2023 conference, Visual Captions is an innovation under the ARChat project. This system offers dynamic visual augmentation during video chats, thus bridging the gap between verbal communication and visual understanding. Visual Captions leverages real-time transcription to suggest appropriate visuals based on open-vocabulary conversations, making it a powerful tool for enhancing remote communications.

A standout feature of this system is its robustness against common errors in real-time speech-to-text transcription, delivering highly accurate visual representations even when faced with textual inaccuracies. The design space of the Visual Captions system includes eight dimensions, allowing different aspects of real-time conversations to be considered. These dimensions are:

  • D1: Temporal – The synchronicity or asynchronicity of visuals with the conversation
  • D2: Subject – Expressing or understanding speech content
  • D3: Visual – The range of visual content, types, and sources
  • D4: Scale – The factors that determine meeting size and scale
  • D5: Space – Co-located or remote settings
  • D6: Privacy – The level of private, shared, or public display of visuals
  • D7: Initiation – Different interaction methods with the system during conversation
  • D8: Effect – The degree to which visuals enhance or distract from the conversation

To evaluate the feasibility and usability of Visual Captions, a user study involving 10 internal participants from diverse backgrounds was conducted. During the study, researchers utilized low-fidelity prototypes and video demos of existing systems to gain insights into participant needs and desires for a real-time visual augmentation service. These discussions ultimately informed the development of the design space covering the eight dimensions described above.

In conclusion, the introduction of Visual Captions and its augmentation of verbal communication with real-time visuals is a game changer for remote video communication. By catering to the various dimensions and complexities of human conversation, this system promises a groundbreaking way to overcome communication barriers and enhance understanding. As we move towards a future where remote work and video conferencing become even more prevalent, the potential for further developments and improvements in this technology is vast, making it an exciting space to watch.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
