CHI 2021 Accessibility FAQ

CHI 2021 is committed to providing an inclusive environment and we will do our best to accommodate requests for special assistance. This page describes the accessibility features of CHI 2021, to help you make an informed decision about whether the conference will be accessible to you. Please contact us if your question is not answered here, or if the conference arrangements as described are not enough to allow you to attend. We will work with you to the best of our ability, to make the conference accessible.





How do I communicate accessibility needs to organizers?


The Accessibility Chairs for CHI 2021 are Chieko Asakawa, Kotaro Hara, and Shari Trewin, whose goal is to ensure the conference is accessible to everyone. When you register for the conference, there will be a registration question labeled, "Please tell us if there is anything we can do to ensure your participation is barrier-free. " Please write-in anything that will help make the conference accessible to you. The accessibility chairs will follow up to discuss your needs in more detail. You can contact them directly at any time by emailing


Please be aware that some accommodations may be difficult to provide at short notice, and we may not be able to accommodate every request.


Are the conference technologies accessible?


The conference will be using the following technologies: Delegate Connect and Zoom.


Delegate Connect. We will be using Delegate Connect as our main virtual conferencing platform. Delegate Connect is a web application. It will host program information and links to virtual sessions. Video presentations and live Q&A sessions for papers and other programs (e.g., workshops) will be streamed using the platform unless otherwise mentioned. Pre-recorded video presentations will have author-provided captions. Sign language interpretation and CART services for sessions will be offered on a per request basis (please contact the accessibility chairs as early as possible so that we can find the service).


Delegate Connect was the most accessible technology among the ones that we tested in the process of deciding the virtual conferencing platform for CHI 2021. The platform’s user interface mostly conformed with WCAG 2.1 AA. The user interface handled magnification and reflow well, so we expect it to be easier to use for people who use zooming and screen magnification on a web browser and a mobile device. The user interface was mostly keyboard navigable; most of the elements on the browser user interface could be accessed using tab (and shift+tab). However, we found some accessibility problems. There were some quirks with keyboard-only interaction: the video player did not allow pausing a video and the platform’s chat user interface could not be navigated using a tab key. Also, on a mobile browser, the main menu could not be found by a blind tester. The platform was mostly screen reader accessible on the desktop browser. The platform provider is trying to address these issues by the time of the conference. The platform can be accessed prior to the conference date. You could test its accessibility, and if you find any issue, let us know so that we will do our best to find a workaround.


We are still figuring out how the platform will be used for the socializing events and meeting with people outside of sessions.


We will update the above information as the conference approaches.


Zoom. Although Delegate Connect's live streaming capability will be used for most parts of the conference, more interactive sessions (e.g. workshops) will occur over Zoom. When using Zoom, we encourage you to turn on video to help lip-reading (a virtual background can be used for privacy). Zoom supports a range of keyboard shortcuts, supports screen reader alerts, and automatic live captioning. If you request sign language interpretation, interpreters can join Zoom sessions that you will be in. Please see the following page for more information about Zoom’s accessibility support: If you request CART service, this will be provided in a separate stream (which can reduce delays).


SIGCHI's Progressive Web App (PWA). SIGCHI’s Progressive Web App will provide you the conference program and schedule.


Will sign language interpretation be available?


Yes, if you request sign language interpretation in your conference registration, Interpretation will be available for all conference presentations and events, including informal conversations. Please register your request before Friday, April 9th. The accessibility chairs will follow up with you and connect you to the interpreters. After that point, we will do our best to accommodate the needs.


For both presenters and audience, interpreters will join synchronous video streaming and live Q&A sessions with you. We are still figuring out the set up, but live Q&A sessions and interpretation will likely be played on different streams. The live sessions will be played on the Delegate Connect’s user interface. In addition, attendees and interpreters will be provided a Zoom room when they join live sessions, where we will pin the interpreters on the screen with the speakers.


Posters and Demos will be held in Zoom meeting rooms so ASL interpreters can follow attendees into those rooms.


If you need support in coordinating with the interpreters which sessions you are joining, please let the Accessibility Chairs know by emailing


You may also bring your own interpreter to the event. Please reach out to the accessibility chairs to set this up.


Will captions be available?


The video presentations will be accompanied by the author-provided captions. CART service will be provided if requested during registration. Please register your request before Friday, April 9th. The accessibility chairs will follow up with you and provide more details on connecting to the captioning service. After that point, we will do our best to accommodate the needs.


Both CART captioners and users will join live sessions on Delegate Connect or Zoom. In addition, attendees will be provided an external link tot he live CART transcript.


For synchronous sessions (e.g., presentation Q&A), automatically generated closed captions will be provided by default on both Zoom and the Delegate Connect's user interface. The captioning engine that the platform uses is Amazon Web Service’s speech recognition engine.


You may also bring your own captioner to the event. Please reach out to the accessibility chairs to set this up.


Will there be a chance to try the videoconferencing and other technologies in advance of the conference?


Yes, if you would like early access and an introductory tour of any of the conference technologies, please reach out to the accessibility chairs on


Will talks be pre-recorded?


At this time we anticipate that all presenters will be requested to pre-record their talks and to provide a transcript for caption generation. If you are a presenter and require assistance with your recording (e.g. someone to voice the talk for you), please reach out to the accessibility chairs on


Is there a detailed agenda with direct links?


The conference agenda will be made available to registered participants over Delegate Connect. The agenda will contain direct links to each session or event. We will update this part of FAQ once we know when this information will be available. Last minute changes to the agenda will be reflected there.


Will talks be available in advance?


Yes, all prerecorded contents will be made available to registered participants. We will update this part of FAQ once we know when the contents will be available.


Can someone assist me with my online participation/presentation?


If you would benefit from assistance in giving your presentation or handling questions, please reach out to the accessibility chairs to make arrangements.


Will presenters be visible?


Presenters and other speakers will be requested to use video when speaking to help lip-reading and non-native speakers. We recognize that this may not be possible for every speaker. Captions will be available as a fall-back for all pre-recorded presentations. If you would rely on captions when presenters are not visible please indicate this in your conference registration or reach out directly to the accessibility chairs.


How will the conference sessions be run?


Participants will be encouraged to use video when speaking, to support lip-reading and non-native speakers. Audience members will have the ability to turn captions on and off.


Conference sessions will have a professional moderator. At the start of each session, if a human captioner is present, the moderator will post a direct link to the caption stream in case of delay with live caption presentation in the videoconferencing technology. If a sign language interpreter is present, the moderator will pin the interpreter’s video to make it visible alongside the presentation and speaker.


We are still working on the details of how participants will ask questions, and how the questions will be moderated and brought to the speakers.


Session moderators will post URLs in chat when they are mentioned.


Will live sessions be recorded?


At this time, we anticipate that live presentation sessions will be recorded and will be made available later on a video streaming platform.


Who should I contact if I have an access problem during the event?


We will provide the primary accessibility support channel during the conference. You may also contact the accessibility chairs on in advance for private backchannel contact information.
