CoSeq is ubiquitous, occurring across diverse situations like trip planning, course scheduling, or book writing. Building a consensus on a sequence is desirable to groups. However, accomplishing this requires groups to dedicate significant effort to comprehensively discuss preferences and resolve conflicts. Furthermore, as numerous decisions must be assessed to construct a sequence, this challenge can be exacerbated in CoSeq. However, little research has aimed to effectively support consensus building in CoSeq. As a first step to systematically understand and support consensus building in CoSeq, we conducted a formative study to gain insights into how visual awareness may facilitate the holistic recognition of preferences and the resolution of conflicts within a group. From the study, we identified design requirements to support consensus building and designed a novel visual awareness technique for CoSeq. We instantiated this design in a collaborative travel itinerary planning system, Twine, and conducted a summative study to evaluate its effects. We found that visual awareness could decrease the effort of communicating preferences by 21%, and participants' comments suggest that it also encouraged group members to behave more cooperatively when building a consensus. We discuss future research directions to further explore the needs and challenges in this unique context and to advance the development of support for CoSeq tasks.<\/jats:p>","DOI":"10.1145\/3449250","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T17:47:23Z","timestamp":1619113643000},"page":"1-29","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Supporting Collaborative Sequencing of Small Groups through Visual Awareness"],"prefix":"10.1145","volume":"5","author":[{"given":"Tae Soo","family":"Kim","sequence":"first","affiliation":[{"name":"KAIST, Daejeon, Republic of Korea"}]},{"given":"Nitesh","family":"Goyal","sequence":"additional","affiliation":[{"name":"Google, New York, NY, USA"}]},{"given":"Jeongyeon","family":"Kim","sequence":"additional","affiliation":[{"name":"KAIST, Daejeon, Republic of Korea"}]},{"given":"Juho","family":"Kim","sequence":"additional","affiliation":[{"name":"KAIST, Daejeon, Republic of Korea"}]},{"given":"Sungsoo Ray","family":"Hong","sequence":"additional","affiliation":[{"name":"George Mason University, Fairfax, VA, USA"}]}],"member":"320","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-155860915-0"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/FUZZY"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/2470654.2470724"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/IV.2009.108"},{"volume-title":"Building United Judgment: A Handbook for Consensus Decision Making","author":"Avery Michael","key":"e_1_2_2_5_1","unstructured":"Michael Avery, Barbara Stribel, Lonnie Weiss, and Brian Auvine. 1981.
