🍑 Tao Long (he/him)

Hi, I'm a second-year Computer Science PhD student at Columbia University, with a focus on human-computer interaction (HCI). I'm fortunate to be advised by Professor Lydia Chilton and part of the ♔ Columbia HCI Group Your GIF Description

My research focuses on making generative AI models more usable, useful, and well-integrated into our everyday workflows. Thus, I build multimodal AI productivity & creativity support tools (yeee🤠!!) Specifically, I am researching the human-AI interaction design with large language models (LLMs) and text-to-image models in the context of workspaces. Before my PhD, I earned my two bachelors with Summa Cum Laude from Cornell University, which unlocked the doors to research and teaching for me. For more info, please refer to my   Curriculum Vitae :)   

please reach out! happy to talk & help out in any way i can 🧡


Below is a list of recent updates, which admittedly focuses on good news. However, I think it's also important to share *bad news*, to normalize sadness, vulnerabilities, rejections, and failures :) While it's far from perfect, you can check some of my thoughts on this other side of the mood blog. If you want, I'm happy to chat! (idea from the amazing Jane Im)

My Info/Sci and Communication background made me understand that technology has both communicative capacity and responsibility. Therefore, as designers and developers, we should speak, design, and build for those who can't. As a junior PhD, I am more than eager to learn and join exciting HCI/AI projects. Don't hesitate to reach out for collab :D

a paper-folded bird is flying. along with the texts: TechTweets: The art of explaining science on social media. Having expertise is one thing. Explaining it is another. At TechTweets, we’re developing online learning tools to help you share your expertise in explanatory Twitter threads, or Tweetorials.

Tweetorial Hooks: Generative AI Tools to Motivate Science on Social Media

Tao Long, Dorothy Zhang, Grace Li, Batool Taraif, Samia Menon, Kynnedy Smith, Sitong Wang, Katy Gero, Lydia Chilton

 ICCC 2023  Tweetorials are popular, but STEM experts struggle to make them engaging. Our system, HookIncubator, utilizes scaffolding and AI chaining with LLMs for co-creating compelling hooks. Our evaluation indicates reduced cognitive load and well-supported science contextualization. Users edits LLM outputs for personal style and clarity, enhancing ownership and motivating more readers.

Social Dynamics of AI Support in Creative Writing

Katy Gero, Tao Long, Lydia Chilton

 CHI 2023  To address the lack of work considering the social-technical gap that LLMs poses on writers, we discover three elements that govern a writer’s interaction with support actors: [1] what writers desire help with (motivation, planning, translating, reviewing) and [2] how writers perceive potential support actors (availability, individuality, trust) and [3] the values writers hold (intention, authenticity, creativity).

ReelFramer: Co-creating News Reels on Social Media with Generative AI

Sitong Wang, Samia Menon, Tao Long, Keren Henderson, Dingzeyu Li, Kevin Crowston, Mark Hansen, Jeffrey Nickerson, Lydia Chilton

 arXiv 2023  News outlets struggle to create news reels that match the style of TikTok. Our system, ReelFramer, uses LLMs and text-to-image models to help journalists explore framings, generate scripts, character boards, and storyboards. Our user study and co-design workshop found it eases the burden of writing, makes the process rewarding, and generates informative and entertaining end results.

An overview of Generative Disco, a generative AI system that facilitates text-to-video generation for music visualization using a large language model and a text-to-image model. The figure depicts four areas: an AUDIO AREA (top left), a BRAINSTORMING AREA (bottom left), a VIDEO AREA (top right), and a TRACKS AREA (bottom right). In the AUDIO area, a user can interact with a waveform representation of music and and define a pair of start and end prompts to parameterize the generation of video clips. In the BRAINSTORMING AREA, a user can brainstorm different subjects and styles for a prompt. In the figure, a user is brainstorming prompts and exploring generations for their high-level goal of showing 'dancing at the disco' within an interval. Highlighted are 'robot DJs, neon dance floor' as a subject suggestion and 'glitch' and 'slow motion' as a style suggestion. In the VIDEO area, a cyberpunk neon figure in motion is depicted as a preview of the generated video. In the TRACKS AREA, frame previews of each generated video are shown in tiles.

Generative Disco: Text-to-Video for Music Visualization

Vivian Liu, Tao Long, Nathan Raw, Lydia Chilton

 arXiv 2023  Visuals enhance our music experience while existing text-to-video tools produce uncanny ones. Our system, Generative Disco, helps generate music visualizations with start and end prompts and design patterns (transition and holds) using LLMs and text-to-image models. With robust user control to mitigate the uncanny, professionals found the system enjoyable, easy to explore, and highly expressive.

Challenges and Opportunities for the Design of Smart Speakers

Tao Long, Lydia B. Chilton

 arXiv 2023  VUIs have opened up many new types of interaction, while they are still underused. We identify opportunity spaces for designers and developers to explore such as focusing on 1) information support while multitasking (cooking, driving, childcare, etc), 2) incorporating users’ mental models, and 3) integrating calm design principles.

Diverging Perspectives from Naive Participants and Social Scientists on Addressing Embodiment in a Virtual Cyberball Task

Tao Long, Swati Pandita, Andrea Won

 CSCW 2023 EA  To address the lack of research on UCD methodologies for social science paradigms, we identify shared considerations and disagreements between naive participants and experienced researchers for future systems: 1) intuitiveness, 2) inclusivity, 3) minimalism.

Multistakeholder Perspectives on Digital Tools for U.S. Asylum Applicants Seeking Healthcare and Legal Information

Aparajita Bhandari, Diana Freed, Tara Pilato, Faten Taki, Gunisha Kaur, Stephen Yale-Loehr, Jane Powers, Tao Long, Natalie Bazarova

 CSCW 2022  A lack of information for asylum applicants negatively impacts their healthcare engagement. We identify four challenges for immigrants using current digital tools: lack of information, inaccessibility, emotional barriers, and lack of cultural sensitivity. The study recommends multiple stakeholders' perspectives when designing future tools.

Teaching & Services

My passion for teaching and socially impactful research significantly contributes to my decision to pursue a PhD and (possibly) an academic career in Computer Science. For the sake of intersectionality, I always remind myself that I am indeed a privileged person along my journey. It helps me rethink myself, my role, and my responsibilities in better helping others with the resources I have. Always eager to contribute to new initiatives ;)
