--- abstract: "Extending Fitts’ law to more than one dimension has been\r\nrecognized as having important implications for HCI. In spite\r\nof the progress made over the years, however, it is still far\r\nfrom a resolved issue. Our work approaches this problem\r\nfrom the viewpoint of a configuration space, which has served\r\nas a useful conceptual framework for understanding human\r\npreference in perception. Notably, human are found to be\r\nbiased towards regular configurations. In this work, we ex-\r\ntended the configuration space framework to the domain of\r\nmotor behavior, analyzed 2D pointing, and developed five\r\nmodels to account for the performance. An extensive experiment was conducted to measure the fit of the derived models\r\nand that of three previous models. Consistent with our hypothesis, the model reflecting a bias towards regular configuration was found to have the most satisfactory fit with the\r\ndata. The paper concludes with discussions on improving\r\nunderstanding of Fitts’ law and the implications for HCI.\r\n" altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: 'April 10, 2010' conference: ACM Conference on Human Factors in Computing Systems (CHI) 2010 confloc: 'Atlanta, GA' contact_email: ~ creators_id: - hyang@us.ibm.com - xuxianggang@gmail.com creators_name: - family: Yang given: Huahai honourific: '' lineage: '' - family: Xu given: 'Xianggang ' honourific: '' lineage: '' date: 2010-04-10 date_type: published datestamp: 2010-02-18 23:41:20 department: ~ dir: disk0/00/00/67/80 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 6780 fileinfo: /style/images/fileicons/application_pdf.png;/6780/1/pap1292%2Dyang.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: inpress issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: "Configuration space, Fitts’ law, 2D pointing\r\n" lastmod: 2011-03-11 08:57:35 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: FALSE publication: ~ publisher: ACM Press refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 22 series: ~ source: ~ status_changed: 2010-02-18 23:41:20 subjects: - appl-cog-psy - cog-psy succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: "Bias towards Regular Configuration in 2D Pointing\r\n" type: confpaper userid: 9651 volume: ~
