CHI’25 Presentation Instructions

Dear Authors,

Congratulations again on having your work accepted at CHI2025! This email is about your presentations, and if you are not the presenting author, please forward this email to the presenting authors. 

This year, we have an exciting and extensive program, with record numbers of technical contents across all tracks! Among them, Papers, Journals, Alt.chi, and Case studies will have oral presentations. While you might have done presentations at CHI, this year, we have a number of differences, so please read the instructions carefully to ensure a great presentation experience:

• To accommodate a record number of oral presentations, the time slot for each presentation is much shorter than previous years, which is 10 minutes for presentations and 2 minutes for Q&A and there will be a maximum number of 7 presentations in a 90-minute session.  
• This year, we have in-person and remote sessions, but both will be held on-site with in-person session chairs and audience. Remote sessions are for authors who cannot attend in-person to present remotely via Zoom to the on-site audience. 
• Remote attendees cannot join the session live via Zoom but could watch presentation videos asynchronously on the SIGCHI Conference Programmes progressive web application (PWA) and ask questions via PWA. 

As such, as a presenter, you should expect: 

• If you present in-person, it will be very much like previous in-person conferences. There will be an HDMI cable to connect with a project. Please ensure that you bring an adapter for HDMI.
• If you present remotely,  simply join the Zoom link, which you can find in the PWA, as you would for a regular online meeting to give your live presentation to an on-site audience. 

Here are the instructions for the presentation:

• Before the presentation, please use PWA to double-check the time/date.
  • For an in-person presentation, also double check the room of the session you are presenting. 
  • For a remote presentation, confirm the Zoom link given in the PWA for the allocated session. Only remote presenters in the session would be allowed to enter by the session chair or SVs during the session. 
• Arrive 20 min before the session starts, check in with your session chair, and test the presentations, leaving plenty of time to fix issues if any. 
  • For an in-person presentation, you will use your own laptop to connect to a projector via HDMI. Please ensure that you bring an adapter for HDMI. Please also bring a copy of your presentation on a USB drive as a backup.
    • There is a dedicated computer in each room to perform auto-captioning. Note that you cannot use that computer to connect to a projector.
  • For a remote presentation, make sure you can connect and present via the Zoom link, and please also have your presentation videos readily available as a backup in case of any technical issues. 
• Please finish within your allocated time which is 12 minutes in total, with 10 minutes for presentation and 2 minutes for Q&A.  If you do not stop and use up all the 12 minutes, there will be no time for Q&A, and you will be cut off by the session chair at the 12 minutes to allow the next presenter to set up
  • For an in-person presentation, pay attention to the session chair’s countdown signals, at the 3, 1, 0 minutes prior 10 minutes to give some time for Q&A.
  • If it is a remote presentation, you will be responsible for keeping track of your time and will also be cut off at the 12 minutes.
• As the time for Q&A in a session is very short this year, you are encouraged to make use of coffee or lunch breaks if you attend the conference in-person. Please also make sure of PWA to interact and carry on discussions, to compensate for the short Q&A time.

How to show your slides in the in-person meeting room

For in-person presenters:

An HDMI cable is on or around a presenter’s table, which is directly connected to a project in the meeting room. You must use this HDMI cable to connect your laptop to show your slides in the meeting room, which is very much like previous in-person conferences.

For remote presenters:

All presenters must join a Zoom meeting for their presentation. Presenters will share their screen on the Zoom meeting to show their slides, which is the same as other Zoom meetings. A laptop that is running Zoom Rooms (meetings) and is connected to a projector in the room, will show your slides via Zoom meetings. 

Even if you cannot connect to a project, please use another computer (e.g., ones owned by other presenting authors). It is a good practice to have a copy of your presentation material in your USB key.

We look forward to your presentations at CHI2025. If you have any questions, please let us know via tpc@chi2025.acm.org.
