However, classical pattern set design and input recognition algorithm of such techniques did not leverage users' behavioral information, which limits their robustness to imprecise inputs. In this paper, we improve these two key components by modeling users' interaction behavior. In the first user study, we asked users to tap a finger in sync with blinking patterns with various period and delay, and modeled their finger tapping ability using Gaussian distribution. Based on the results, we generated pattern sets for up to 22 targets that minimized the possibility of confusion due to imprecise inputs. In the second user study, we validated that the optimized pattern sets could reduce error rate from 23% to 7% for the classical Correlation recognizer. We also tested a novel Bayesian, which achieved higher selection accuracy than the Correlation recognizer when the input sequence is short. The informal evaluation results show that the selection technique can be effectively scaled to different modalities and sensing techniques.<\/jats:p>","DOI":"10.1145\/3369839","type":"journal-article","created":{"date-parts":[[2019,12,12]],"date-time":"2019-12-12T13:16:03Z","timestamp":1576156563000},"page":"1-24","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":38,"title":["Facilitating Temporal Synchronous Target Selection through User Behavior Modeling"],"prefix":"10.1145","volume":"3","author":[{"given":"Tengxiang","family":"Zhang","sequence":"first","affiliation":[{"name":"Tsinghua University, Institute of Computing Technology, Chinese Academy of Sciences, Kexueyuan South Road, Beijing"}]},{"given":"Xin","family":"Yi","sequence":"additional","affiliation":[{"name":"Key Laboratory of Pervasive Computing, Ministry of Education, Beijing Key Lab of Networked Multimedia, Beijing National Research Center for Information Science and Technology, Department of Computer Science and Technology, Tsinghua University"}]},{"given":"Ruolin","family":"Wang","sequence":"additional","affiliation":[{"name":"Tsinghua University, UCLA"}]},{"given":"Jiayuan","family":"Gao","sequence":"additional","affiliation":[{"name":"Global Innovation eXchange Institute, Key Laboratory of Pervasive Computing, Ministry of Education, Beijing Key Lab of Networked Multimedia, Department of Computer Science and Technology, Tsinghua University, Shuangqing Road, Beijing"}]},{"given":"Yuntao","family":"Wang","sequence":"additional","affiliation":[{"name":"Global Innovation eXchange Institute, Key Laboratory of Pervasive Computing, Ministry of Education, Beijing Key Lab of Networked Multimedia, Department of Computer Science and Technology, Tsinghua University, Shuangqing Road, Beijing"}]},{"given":"Chun","family":"Yu","sequence":"additional","affiliation":[{"name":"Global Innovation eXchange Institute, Key Laboratory of Pervasive Computing, Ministry of Education, Beijing Key Lab of Networked Multimedia, Department of Computer Science and Technology, Tsinghua University, Shuangqing Road, Beijing"}]},{"given":"Simin","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computing Engineering, Beihang University, Beijing"}]},{"given":"Yuanchun","family":"Shi","sequence":"additional","affiliation":[{"name":"Tsinghua University, Shuangqing Road, Beijing"}]}],"member":"320","published-online":{"date-parts":[[2020,9,14]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-003-1552-z"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/3214263"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/2935334.2935389"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/2493432.2493515"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/SMC.2016.7844384"},{"key":"e_1_2_2_6_1","volume-title":"SEQUENCE: a remote control technique to select objects by matching their rhythm.
