Virtual / online tools used in CHI 2023

CHI 2023 is organized as a hybrid event to include as many participants as we can. We hope to create a great experience for everyone – whether they are onsite or online!

In CHI 2023, online tools are used for different purposes, as explained below. For the reasoning behind this year’s CHI hybrid approach, please read this blog post.

You can ask questions about the online tools in Discord or by sending email to the virtual chair: [email protected]

The following content items are only available in asynchronous mode. Therefore, there are no online (synchronous) sessions for:

  • Papers
  • Case Studies of HCI in Practice
  • Late-Breaking Work
  • Interactivity
  • alt.chi
  • Journals

For these content items, video recordings of the talks by the authors are available in the Progressive Web App (PWA). There is no online schedule for them, and remote participants can watch them at their preferred time, and comment in PWA – see below for instructions.

PWA (Progressive Web App)

The Progressive Web App (PWA) can be used in a web browser and users should log in to get the full functionality. You can find the entry page on the CHI 2023 program web page or here: https://programs.sigchi.org/chi/2023/program/all

The PWA is used for asynchronous Q&A and discussions for the following content items:

  • Papers
  • Case Studies of HCI in Practice
  • Late-Breaking Work
  • Interactivity
  • alt.chi
  • Journals

Login to PWA requires a personal ACM account. This can be set up for free at: https://accounts.acm.org/. Please make sure to use the same email address as in your CHI 2023 registration to have all features available as a registered participant.

You can discuss a particular session or individual content item (such as paper) by searching for it on the technical program. There is a comment box below each content item/paper.

Offline authors (authors who do not present at the conference in person) have two weeks to answer the questions in PWA.


Discord is used for General Discussions including overall technical aspects but also social chatting during CHI 2023. It requires a personal account to log in. A personal account can be created for free at https://discord.com/. With this, you can join the CHI 2023 Discord here (https://discord.gg/ErHF5WcHeV). There will also be a physical QR Code for CHI 2023 Discord at the conference.

  • The first thing you should do is to introduce yourself on the ⁠👋- introduce-yourself-first channel, which has two purposes. First, if you like, you can start by stating your name and tell us a little about yourself. Second, to check if you are registered at CHI2023, but for that, we need some information from you. If you are willing to write your email address (the one you registered with) on the channel, we can directly check and let you in. If you prefer not to disclose your email address here, please email to [email protected] with the subject ‘Access for DISCORD’ stating your registration confirmation. We can then grant you access to all CHI Discord channels.
  • Ask any questions that you may have at the help-desk channel regarding the virtual experience.
  • The followings channels are initially set up:
    • CHI (for general technical discussions)
    • Meeting people (for social interactions)
    • Global Plaza
    • help-desk (Questions about the use of virtual tools)
  • If you want to ask questions regarding a particular paper or other content item, please use PWA, as outlined above.


Slido is used for synchronous Q&A only. It does not require a personal account and both in-person and remote attendees can use it.
It will be used in these hybrid sessions:

  • Keynotes
  • SIGs
  • Panels
  • Global Plaza

Join Slido here (https://app.sli.do/event/16evvTBrn2xVaGRgvLspJu). There will also be a physical QR Code at the conference.

Upon entering Slido, please choose the correct session room before typing your questions.

Zoom for Hybrid Sessions

Zoom used for remote attendees to participate in hybrid sessions:

  • Competitions
  • Some Workshops (it is mentioned separately which)
  • SIGs
  • Panels

To use Zoom, a personal or institutional account is required. If you do not have an account, you can create a free Zoom account at https://zoom.us/.

Each physical room has a Zoom link associated. You can check the links for the hybrid sessions at their corresponding descriptions in the technical program (you need to be logged into PWA using your ACM account).

Besides the remote attendees, the in-person presenters will also need to join the Zoom meeting in their room. There will also be physical QR Codes at the corresponding sessions.

Beware that non-hybrid sessions (Papers, Case Studies, Late-Breaking Work, Interactivity, alt.chi, Journals) will not support hybrid attendance (even if there is a Zoom link).

After joining one hybrid Zoom link, use your registration name.

  • You will then be put into a waiting room until the moderator allows you to enter.
  • You should show up 15 minutes before so that we have time to check everyone.
  • By default, remote attendees will have their microphones and cameras blocked by the moderator.
    • If someone wishes to speak, they should ask permission.
    • Furthermore, Zoom chat will be disabled except to reach the hosts.
      • If you want to ask questions, use Slido if available, or ask for permission to speak.
  • Automated captions will be available in these sessions.

Zoom for Auto-Captioning

Zoom is used for captioning as an accessibility feature. It is only for generating automated captions for accessibility for in-person attendees – it is not for remote attendees.

  • All rooms at the conference will be supported with a Zoom link for captioning.
  • Zoom will only record the presenter’s audio to generate captions that all in-person attendees can access.
  • The presenters will need to log in to the Zoom meeting in their room in order for the audio to be captured in good quality to ensure captioning is working.
  • The links to join the Zoom for captioning will be available in physical QR Codes at the corresponding sessions in the conference center.
  • As an in-person attendee, you can read the captions on your personal device by logging into the same session (also using the QR code in the room).
  • During these sessions, please turn off the sound of the device you are using to read the captions.
