In analogy to these characters, we explore the concept of migration: Process by which an agent moves between embodiments, being active in only one at a time. We developed an autonomous artificial pet with two embodiments: A virtual within a smartphone and a physical robotic embodiment. Considering that owners' interactions with real pets lead to emotional attachment and potentially related health benefits, we conducted a user study with elementary school students to assess their attachment to the prototype and how natural they felt the interaction was. By the end of the experiment children felt closer to the artificial pet and 43.3% considered the two embodiments to correspond to the same entity, although migration was never explained to them. As a result, this paper presents a novel generic methodology that allows the evaluation of other implemented prototypes that support migration. Furthermore, we created a set of design guidelines for migrating agents. <\/jats:p>","DOI":"10.1142\/s0219843614500017","type":"journal-article","created":{"date-parts":[[2014,3,18]],"date-time":"2014-03-18T22:06:56Z","timestamp":1395180416000},"page":"1450001","source":"Crossref","is-referenced-by-count":11,"title":["Migration Between Two Embodiments of an Artificial Pet"],"prefix":"10.1142","volume":"11","author":[{"given":"Paulo F.","family":"Gomes","sequence":"first","affiliation":[{"name":"Games and Playable Media Group and Computer Science Department, University of California Santa Cruz, Santa Cruz, CA 95064, USA"}]},{"given":"Alberto","family":"Sardinha","sequence":"additional","affiliation":[{"name":"INESC-ID and Instituto Superior T\u00e9cnico, University of Lisbon, 2744-016, Porto Salvo, Portugal"}]},{"given":"Elena","family":"M\u00e1rquez Segura","sequence":"additional","affiliation":[{"name":"Uppsala University, Uppsala, Sweden"},{"name":"Exertion Games Lab, RMIT University, Melbourne, Victoria 3000, Australia"}]},{"given":"Henriette","family":"Cramer","sequence":"additional","affiliation":[{"name":"Yahoo Labs, Sunnyvale, CA, USA"}]},{"given":"Ana","family":"Paiva","sequence":"additional","affiliation":[{"name":"INESC-ID and Instituto Superior T\u00e9cnico, University of Lisbon 2744-016, Porto Salvo, Portugal"}]}],"member":"219","published-online":{"date-parts":[[2014,4,8]]},"reference":[{"key":"rf2","volume-title":"An Introduction to Multiagent Systems","author":"Wooldridge M.","year":"2008"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1007\/s12369-008-0002-2"},{"key":"rf5","unstructured":"P.\u00a0Milgram, Photonics for Industrial Applications (International Society for Optics and Photonics, 1995)\u00a0pp. 282\u2013292."},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1080\/00094056.2005.10522248"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.2752\/089279399787000390"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.1177\/0002764203255213"},{"key":"rf14","volume-title":"Flow: The psychology of optimal experience","author":"Csikszentmihalyi M.","year":"1990"},{"key":"rf17","doi-asserted-by":"publisher","DOI":"10.1561\/1100000005"},{"key":"rf18","doi-asserted-by":"publisher","DOI":"10.1142\/S0219843606000795"},{"key":"rf19","doi-asserted-by":"publisher","DOI":"10.1142\/S0219843613500102"},{"key":"rf32","doi-asserted-by":"publisher","DOI":"10.1007\/978-94-007-0582-1_8"},{"key":"rf35","volume-title":"Attachment Theory and Close Relationships","author":"Brennan K.
