One obstacle preventing their smooth integration is our limited understanding of how humans may perceive and react to robot motion. Motivated by recent studies highlighting the benefits of intent-expressive motion for robots operating close to humans, we describe Social Momentum (SM), a planning framework for legible robot motion generation in multiagent domains. We investigate the properties of motion generated by SM via two large-scale user studies: an online, video-based study (\n            <jats:italic>N<\/jats:italic>\n            = 180) focusing on the legibility of motion produced by SM and a lab study (\n            <jats:italic>N<\/jats:italic>\n            = 105) focusing on the perceptions of users navigating next to a robot running SM in a crowded space. Through statistical and thematic analyses of collected data, we present evidence suggesting that (a) motion generated by SM enables quick inference of the robot\u2019s navigation strategy; (b) humans navigating close to a robot running SM follow comfortable, low-acceleration paths; and (c) robot motion generated by SM is positively perceived and indistinguishable from a teleoperated baseline. Through the discussion of experimental insights and lessons learned, this article aspires to inform future algorithmic and experimental design for social robot navigation.\n          <\/jats:p>","DOI":"10.1145\/3495244","type":"journal-article","created":{"date-parts":[[2022,2,8]],"date-time":"2022-02-08T13:04:39Z","timestamp":1644325479000},"page":"1-37","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":48,"title":["Social Momentum: Design and Evaluation of a Framework for Socially Competent Robot Navigation"],"prefix":"10.1145","volume":"11","author":[{"given":"Christoforos","family":"Mavrogiannis","sequence":"first","affiliation":[{"name":"Sibley School of Mechanical &amp; Aerospace Engineering, Cornell University, Seattle, WA, USA"}]},{"given":"Patr\u00edcia","family":"Alves-Oliveira","sequence":"additional","affiliation":[{"name":"ISCTE-University Institute of Lisbon, Portugal"}]},{"given":"Wil","family":"Thomason","sequence":"additional","affiliation":[{"name":"Department of Computer Science,Cornell University, Ithaca, NY, USA"}]},{"given":"Ross A.","family":"Knepper","sequence":"additional","affiliation":[{"name":"Department of Computer Science,Cornell University, Ithaca, NY, USA"}]}],"member":"320","published-online":{"date-parts":[[2022,2,8]]},"reference":[{"key":"e_1_3_2_2_2","unstructured":"https:\/\/suitabletech.com\/ Suitable Technologies Inc."},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/casp.677"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.2307\/1969218"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cognition.2009.07.005"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12369-008-0001-3"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.5555\/2531382"},{"key":"e_1_3_2_8_2","doi-asserted-by":"crossref","unstructured":"N.
