Symposium program

Due to COVID 19, unfortunately there will not be any ETRA 2020 event, neither physical nor virtual. However, all accepted papers will be published in the ACM Digital Library.

The organizers of the COGAIN symposium, on the other hand, would like to arrange a two-hour virtual session on the 26th of June (2-4 pm CET), where everybody can participate. This will allow the authors to answer possible questions and for everyone to discuss papers.

We would like to invite everyone to join our virtual event on June 26th.

We are honored to announce Kati van der Hoeven-Lepistö as our special keynote for our virtual event this year:

Kati van der Hoeven-Lepistö is an Author, Speaker, Blogger, Vlogger, and a Model.

Kati is a board member of COGAIN, an ambassador for Miss Wheelchair World, and an honorary ambassador/vice-president of SpecialEffect UK.

Kati is also almost entirely paralyzed. She has had LIS (Locked-In Syndrome) since 1995. Everything Kati has done in her life despite being paralyzed is with the use of technology. To be more precise, she has been to reach so far is by using communication devices that were created to help the less abled.

In her talk, “What a difference a ‘Gaze’ makes”, Kati is going to tell about how she uses the various devices. What being able to have the technology that helps her do everything means to her. And, what are the challenges and what can be done to take on these issues.

Since ACM ETRA 2020 was canceled, Kati’s talk will be published as a video and she will also join the COGAIN 2020 virtual session.

Please, join the virtual session, and do not miss out on the talk of this incredible woman!
