Apart from dedicated classroom study, second language (L2) learners often lack opportunities to switch their attention to vocabulary learning over other daily routines. In this work, we propose a method that enables L2 learners to study new vocabulary items during their dead time, such as when commuting to school or work. We developed a smartphone application, VocaBura, which combines audio learning with location-relevant L1-L2 word pairs to allow users to discover new vocabulary items while walking past buildings, shops and other locations. Our evaluation results indicated that Japanese beginner level English learners were able to retain more vocabulary items with the proposed method compared to traditional audio-based study despite being less aware of L2 vocabulary acquisition having occurred. In our second study, we report on the level of English vocabulary coverage for L2 learning achievable with our proposed method. We discuss several design implications for educational technologies supporting second language learning.<\/jats:p>","DOI":"10.1145\/3369824","type":"journal-article","created":{"date-parts":[[2019,12,12]],"date-time":"2019-12-12T13:16:03Z","timestamp":1576156563000},"page":"1-23","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":21,"title":["VocaBura"],"prefix":"10.1145","volume":"3","author":[{"given":"Ari","family":"Hautasaari","sequence":"first","affiliation":[{"name":"Interfaculty Initiative in Information Studies, The University of Tokyo, Hongo, Bunkyo-ku, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeo","family":"Hamada","sequence":"additional","affiliation":[{"name":"Interfaculty Initiative in Information Studies, The University of Tokyo, Hongo, Bunkyo-ku, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuntaro","family":"Ishiyama","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology, The University of Tokyo, Hongo, Bunkyo-ku, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shogo","family":"Fukushima","sequence":"additional","affiliation":[{"name":"Interfaculty Initiative in Information Studies, The University of Tokyo, Bunkyo-ku, Tokyo, Japan, PRESTO, Japan Science and Technology Agency (JST), Kawaguchi, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2020,9,14]]},"reference":[{"key":"e_1_2_2_1_1","first-page":"71","article-title":"Intentional vs. incidental vocabulary learning","volume":"1","author":"Ahmad Jameel","year":"2012","journal-title":"ELT Research Journal"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.3102\/0013189X018001032"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-4781.1996.tb01159.x"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/2207676.2208598"},{"key":"e_1_2_2_5_1","volume-title":"Working Papers in Applied Linguistics","volume":"4","author":"Dornyei Zoltan","year":"1998"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/2371574.2371640"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/2371574.2371641"},{"key":"e_1_2_2_8_1","volume-title":"Proceedings of the SIGCHI Conference on Human Factors in Computing Systems (CHI '11)","author":"Edge Darren","year":"1978"},{"key":"e_1_2_2_9_1","unstructured":"Damien Elmes. 2008.
