We cordially invite you to the 2nd BCI Un-Conference (BCI-UC) on February 10 and 11, 2021, from 03:00 pm to 08:00 pm (CET)! https://bciunconference.univie.ac.at/2nd-bci-uc/ The BCI-UC is an online un-conference that provides rapid dissemination of novel research results in the BCI community. The BCI-UC does not publish conference proceedings. As such, submitted abstracts can report novel as well as already published work. The BCI-UC does not have a program committee that reviews submitted abstracts. Instead, all registered participants can vote which of the submitted abstracts they would like to see presented at the un-conference. Registration and attendance are free-of-charge. The second BCI-UC will feature keynotes by Marco Congedo [3] on Riemannian transfer learning and by Camille Jeunet on user-centered BCI design [4]. All presentations of the first BCI-UC, which >300 participants attended, can be re-watched at [2]. Registration and abstract submission are open as of today [1]. Voting on submitted abstracts begins on January 13th. Abstract submission remains open until January 25th, 11:59 pm (CET). The voting phase ends on January 27th, 11:59 pm (CET). We will invite the authors of the top-voted abstracts to present their work at the un-conference. For the 2nd BCI-UC, we solicit two types of submissions: * _Presentations_ are applications for 20 minutes slots by a single presenter. * _Mini-symposia_ are applications for 60 minutes slots by multiple presenters on a coherent topic, possibly including a panel discussion. Submissions are text-only. The length and format of the submissions are up to the authors -- use whatever format you consider best for attracting up-votes! Voting procedures will not distinguish between the two submission types, i.e., the community decides on the fraction of presentations vs. mini-symposia. Join us in supporting this novel community-driven dissemination of research results!
