Call For Papers
UbiComp is a premier interdisciplinary venue in which leading international researchers, designers, developers, and practitioners in the field present and discuss novel results in all aspects of ubiquitous and pervasive computing. This includes the design, development, and deployment of ubiquitous and pervasive computing technologies and the understanding of human experiences and social impacts that these technologies facilitate.

UbiComp 2020 will be held from 12th to 16th September, and as in past years will be co-located with ISWC 2020 (with a single registration fee).

There will be a new presentation format for IMWUT papers and ISWC full and short papers accepted for Ubicomp/ISWC 2020. More details to come.

New Publication Model
Starting with the 2017 edition, UbiComp adopts the journal publication model. Papers accepted at the Proceedings of the ACM on Interactive, Mobile, Wearable, and Ubiquitous Technologies (IMWUT) would be invited for presentation at Ubicomp. IMWUT has 1 volume per year with 4 issues per volume, published in March (Issue 1), June (Issue 2), September (Issue 3), and December 1 (Issue 4).

The UbiComp 2020 main technical tracks will consist of papers in IMWUT 2019 Issue 4 and IMWUT 2020 Issues 1-3. Authors of these papers will be invited, but are not obliged, to present at UbiComp. The conference will retain its workshop, poster, and demo tracks, which will have their own publication outlet.

Detailed information about IMWUT -- including submission instructions and a description of its reviewing process -- is available at: http://imwut.acm.org. Information about the rationale for changing the publication model is available below.

Submission Deadlines And Associated Publication Issues
IMWUT has 4 deadlines per year: February 15, May 15, August 15, and November 15. We expect a quick publication schedule. For instance, papers submitted on February 15 may be published as soon as in the June issue, if the review process indicates only minor revisions are required.

AUGUST 15, 2019
Papers with minor revisions will appear in IMWUT 2019 Issue 4 (December 1, 2019)
Papers with major revisions which are subsequently accepted may appear in IMWUT 2020 Issue 1 or IMWUT 2020 Issue 2 depending on the resubmission deadline chosen by the author.
NOVEMBER 15, 2019
Papers with minor revisions will appear in IMWUT 2020 Issue 1 (March 1, 2020)
Papers with major revisions which are subsequently accepted may appear in IMWUT 2020 Issue 2 or IMWUT 2020 Issue 3 depending on the resubmission deadline chosen by the author
FEBRUARY 15, 2020
Papers with minor revisions will appear in IMWUT 2020 Issue 2 (June 1, 2020)
Papers with major revisions which are subsequently accepted may appear in IMWUT 2020 Issue 3 or IMWUT 2020 Issue 4 depending on the resubmission deadline chosen by the author. Papers appearing in Issue 4 will be invited to be presented at UbiComp 2021, not UbiComp 2020!
MAY 15, 2020
Papers with minor revisions will appear in IMWUT 2020 Issue 3 (September 1, 2020)
Papers with major revisions which are subsequently accepted may appear in IMWUT 2020 Issue 4 or IMWUT 2021 Issue 1 depending on the resubmission cycle chosen by the author, and would be invited to be presented at UbiComp 2021.
AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of your conference. The official publication date affects the deadline for any patent filings related to published work. (For those rare conferences whose proceedings are published in the ACM Digital Library after the conference is over, the official publication date remains the first day of the conference.)
Reviewing
All submissions will be reviewed by the IMWUT Editorial Board. Authors can expect a decision about their paper within 8 weeks from the submission deadline. For more information about the review process please refer to: http://imwut.acm.org.

Rationale For Changing The Publication Model
A thorough, rigorous review & publication model has allowed UbiComp to thrive as a highly selective and lively conference. However, the current process has several limitations:

A single yearly submission deadline means authors must conduct and complete their research projects by a specific time in order to submit papers about their work for review.
PC members, without the ability to request major modifications, often have to reject promising work.
A subsequent “journal version” of a conference article is difficult to develop because the original contribution would have already been published. This also duplicates reviewing efforts.
These issues impact nearly all computer science conferences and have been broadly discussed. They are especially challenging for a community like UbiComp that strives to encourage research that crosses disciplinary lines. Recently, the ACM proposed the creation of a “Proceedings of the ACM (PACM)” journal series, to allow conferences to transition to journal-based publishing with hybrid publication and review models. UbiComp has received approval to be one of the first PACM series. This model has been successful for conferences such as VLDB and SIGGRAPH in the past. The expected benefits of this change are two-fold:

Authors: Flexibility in submission timing and integration of (1) high visibility through presentation in a tier 1 conference, (2) journal quality reviews, (3) guaranteed timeliness of reviews, and (4) archival “journal version” of their complete work including full technical details.
Community: A change of reviewing focus that enables the reviewers to ask for important modifications from promising work. Additional review periods should allow growth of high quality submissions and the novel model should draw more researchers.
History And Future Plans
The current UbiComp conference was established in 2013 with the merger of two international conferences, Ubiquitous Computing and Pervasive Computing, which had existed since 1999 and 2002, respectively (see the Past Conferences page for more details). This joint conference is widely considered to be the premier ACM forum on Ubiquitous Computing and related topics. Submissions to the conference average between 400-500/year and the acceptance rate over the past few years has been 20-25%. The conference regularly attracts 600-800 participants each year. This makes UbiComp one of the largest events sponsored by ACM SIGCHI or SIGMOBILE, the two ACM SIGs that co-sponsor UbiComp.

In 2015, ACM introduced a new series of journals under the umbrella of Proceedings of the ACM (PACM). The goal for each of these new journals is to provide an alternative journal-based publication model for major conferences that ACM sponsors. Each PACM title will cross multiple conference communities, and so the name of the journal is chosen to best represent a range of related conferences. One of the first PACM titles to be established was IMWUT: Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies. Its title was chosen to suit conferences that deal with technologies and applications that involve interaction with end users in the post-PC era, including mobile, wearable and otherwise ubiquitous designs.

UbiComp is the first conference to join IMWUT. From 2017 onwards, UbiComp no longer considers full paper or note submissions but will invite for presentation papers published on IMWUT. Both ACM SIGMOBILE and SIGCHI are supportive of this decision. The UbiComp conference will maintain its own Steering Committee (http://www.ubicomp.org/sc/), with an elected chair (currently Prof. Koji Yatani from University of Tokyo).

It is envisioned that other high-quality conferences will form an association with IMWUT in the future. The IMWUT Editorial Board will actively solicit and review proposals from other conferences whose subject matter and editorial policy are of appropriate standard.

When new conferences join IMWUT, papers presented at UbiComp will be distinguished from papers presented at other conferences through different sections within each issue of the journal. There will also be separate Editorial boards for each conference, as there were separate Technical Program Committees in the past.
