--- abstract: |- This study argues how a human infant acquires the ability of joint attention through interactions with its caregiver from the viewpoint of a constructive approach. This paper presents a constructive model by which a robot acquires a sensorimotor coordination for joint attention based on visual attention and learning with self-evaluation. Since visual attention does not always correspond to joint attention, the robot may have incorrect learning situations for joint attention as well as correct ones. However, the robot is expected to statistically lose the data of the incorrect ones as outliers through the learning, and consequently acquires the appropriate sensorimotor coordination for joint attention even if the environment is not controlled nor the caregiver provides any task evaluation. The experimental results suggest that the proposed model could explain the developmental mechanism of the infant’s joint attention because the learning process of the robot’s joint attention can be regarded as equivalent to the developmental process of the infant’s one. altloc: - http://www.lucs.lu.se/ftp/pub/LUCS_Studies/LUCS101/Nagai.pdf chapter: ~ commentary: ~ commref: ~ confdates: 'August 4-5, 2003' conference: 'Third International Workshop on Epigenetic Robotics: Modeling Cognitive Development in Robotic Systems' confloc: 'Boston, MA, USA' contact_email: ~ creators_id: [] creators_name: - family: Nagai given: Yukie honourific: '' lineage: '' - family: Hosoda given: Koh honourific: '' lineage: '' - family: Asada given: Minoru honourific: '' lineage: '' date: 2003 date_type: published datestamp: 2004-02-12 department: ~ dir: disk0/00/00/33/35 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: Prince given: Christopher G. honourific: '' lineage: '' - family: Berthouze given: Luc honourific: '' lineage: '' - family: Kozima given: Hideki honourific: '' lineage: '' - family: Bullock given: Daniel honourific: '' lineage: '' - family: Stojanov given: Georgi honourific: '' lineage: '' - family: Balkenius given: Christian honourific: '' lineage: '' eprint_status: archive eprintid: 3335 fileinfo: /style/images/fileicons/application_pdf.png;/3335/1/Nagai.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub 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: 'joint attention, visual attention, self-evaluation, robotic learning' lastmod: 2011-03-11 08:55:25 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: 91-98 pubdom: TRUE publication: ~ publisher: Lund University Cognitive Studies refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 12 series: ~ source: ~ status_changed: 2007-09-12 16:50:08 subjects: - comp-sci-mach-learn - comp-sci-robot succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: 'How does an infant acquire the ability of joint attention?: A Constructive Approach' type: confpaper userid: 3507 volume: 101
