We envision an innovation through mobile computing technologies to empower such crowds. We present Card-stunt as a Service (CaaS), a mobile service allowing them to instantly create a massive collective visualization by simply holding their phones up. The key challenge is to achieve instant, infrastructurefree, decimeter-level localization of individuals in a massively packed crowd, within a low latency. CaaS addresses the challenges by mobile visible-light sensing and scalable constrained optimization. Within less than a minute, each person is given individualized pixels so that they can do their part in the overall visualization*.<\/jats:p>","DOI":"10.1145\/3191789.3191797","type":"journal-article","created":{"date-parts":[[2018,3,1]],"date-time":"2018-03-01T15:27:23Z","timestamp":1519918043000},"page":"16-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Card-Stunt as a Service"],"prefix":"10.1145","volume":"21","author":[{"given":"Chungkuk","family":"Yoo","sequence":"first","affiliation":[{"name":"KAIST, Daejeon, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Inseok","family":"Hwang","sequence":"additional","affiliation":[{"name":"IBM Research, Austin, TX"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seungwoo","family":"Kang","sequence":"additional","affiliation":[{"name":"KOREATECH, Cheonan, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myung-Chul","family":"Kim","sequence":"additional","affiliation":[{"name":"IBM Corporation, Austin, TX"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seonghoon","family":"Kim","sequence":"additional","affiliation":[{"name":"KAIST, Daejeon, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daeyoung","family":"Won","sequence":"additional","affiliation":[{"name":"KAIST, Daejeon, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Gu","sequence":"additional","affiliation":[{"name":"Visa, Austin, TX"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junehwa","family":"Song","sequence":"additional","affiliation":[{"name":"KAIST, Daejeon, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2018,2,28]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"South Korean protesters march against president again. http:\/\/edition.cnn.com\/2016\/11\/12\/asia\/south-korean-protest-president-park  South Korean protesters march against president again. http:\/\/edition.cnn.com\/2016\/11\/12\/asia\/south-korean-protest-president-park"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/3081333.3081357"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/2858036.2858286"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/1322263.1322265"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.5555\/2930611.2930623"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-31205-2_3"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/2207676.2208378"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/2906388.2906399"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/2307636.2307645"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/2639108.2639110"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1145\/800195.805928"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1145\/2906388.2906401"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1145\/2462456.2464450"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1145\/2594368.2594393"}],"container-title":["GetMobile: Mobile Computing and Communications"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/3191789.3191797","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/dl.acm.org\/doi\/pdf\/10.1145\/3191789.3191797","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,18]],"date-time":"2025-06-18T02:26:42Z","timestamp":1750213602000},"score":1,"resource":{"primary":{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/3191789.3191797"}},"subtitle":["Empowering a Massively Packed Crowd for Instant Collective Expressiveness"],"short-title":[],"issued":{"date-parts":[[2018,2,28]]},"references-count":14,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2018,2,28]]}},"alternative-id":["10.1145\/3191789.3191797"],"URL":"https:\/\/doi.org\/10.1145\/3191789.3191797","relation":{},"ISSN":["2375-0529","2375-0537"],"issn-type":[{"type":"print","value":"2375-0529"},{"type":"electronic","value":"2375-0537"}],"subject":[],"published":{"date-parts":[[2018,2,28]]},"assertion":[{"value":"2018-02-28","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
