This year, the ACM Hypertext Conference will run on hybrid mode. Both online and in-person presentations will be streamed, and most of the activities will be setup to increase the experience for in-person interaction.

HT’22 conference organizers seek to foster an accessible and inclusive conference. We recognize that ACM HT’22 attendees have differing abilities to pay, and have instituted a tiered pricing program to accommodate different financial needs.

Important: see the Venue page for information concerning the conference hotel and how a direct booking can be made.

Discounted registrations

In striving for a conference cost that is affordable for all, we also have deeply discounted rates available for those registering in countries designated by ACM as “economically developing”. These tickets are supported by SIGWEB to provide fair access.

Know more about grants and support

In addition, the conference will be co-located with the ACM Web Science Conference and the ACM UMAP Conference, and participants that register for both conferences will receive a special 20% discount to all rates. We encourage you to enjoy an entire week in Barcelona, to discuss the most interesting topics together. See more information in the same link above.

Discounted prices might be limited to a particular amount of registrations. If you have questions about price or eligibility, please email us. Important: if you are planning to apply for one of the supported grants, do not register until you get a response, since a discounted code will be provided instead of refunds.

Important Information

Before you start your registration, please make sure you have the following information ready (if applicable):

  • At least one author of accepted papers must register for the conference under an author rate, either online or in-person.
  • The student rate is available only to those who have student status at the time of the conference. Students will be required to submit a proof of student status (a scanned copy in jpg/jpeg or PDF format of their student ID) during registration.
  • ACM Members will be requested to fill in their ACM Membership Number (7 digits) on the registration form to prove their status, i.e., they are current ACM members.

  • Recordings of sessions, chats, questions and answers will be captured during the conference for later viewing. By registering for this event, you are granting permission to record your comments and questions during sessions. Please note: You cannot register for this event unless you give consent.
  • One registration covers one participant. Your registration is strictly personal and must not be transferred to another person.
  • Onsite registration includes coffee breaks, lunch and receptions for the three days of conferences and the workshops (or only workshops for this type of registration).
