Roel Vertegaal
Roeland "Roel" Vertegaal (born July 13, 1968) is a Dutch-Canadian interaction designer, scientist, musician and entrepreneur working in the area of Human-Computer Interaction. He is the director of the Human Media Lab and Professor at Queen's University's School of Computing. He is best known for his pioneering work on flexible and paper computers, with systems such as PaperWindows (2004),〔 PaperPhone (2010)〔 and PaperTab (2012).〔 He is also known for inventing ubiquitous eye input, such as Samsung's Smart Pause technologies, and BitDrones, one of the first programmable matter user interfaces.
==Early life==
Vertegaal grew up near Leiden in the Netherlands, where he attended Bonaventura grammar school. At age 9, he started experimenting with electronic music on a Yamaha CS-30. At age 15, he programmed his first computer games in Apple IIe BASIC. At age 17 he directed his first video clip, studying film with Frans Zwartjes at the Free Academy in The Hague. In 1987, he enrolled at the Utrecht Conservatory, becoming a Mac OS coder and professional pianist. He graduated in 1992 with a Major in Electronic Music and Minor in Jazz Piano, and was awarded the prestigious VSB Scholarship by Dutch author Boudewijn Büch.
In 1992, and supported by Apple's Advanced Technology Group, Vertegaal obtained an MPhil in Computer Science at Bradford University, studying with Prof. Eaglestone. There, he designed a simple user interface for FM synthesis using two 2D perceptually arranged sound maps, discovering that perceptual integrality of sound parameters could be measured through browsing action.〔Vertegaal R., and Bonis E. (1994). ISEE: An Intuitive Sound Editing Environment. Computer Music Journal (18)2 (Summer, 1994), pp. 21-29.〕 His intuitive sound editing interface was deployed in concerts in Vienna in the mid-nineties by computer music pioneer Tamas Ungvary as part of his SensOrg instrument, and is now a common feature of commercial sound synthesis software. In 1994, Vertegaal developed one of the first inline PC webcams, (FrameServer ), deployed by Apple co-founder Steve Wozniak. In 1998, Vertegaal obtained a PhD in Human-Computer Interaction from Twente University, with a committee including Profs Van der Veer and Bill Buxton. There, he studied effects of eye contact on multiparty videoconferencing, pioneering eye input with the GAZE Groupware System,〔Vertegaal, R. 1999. The GAZE groupware system: mediating joint attention in multiparty communication and collaboration. In Proceedings of the SIGCHI Conference on Human Factors in Computing Systems (CHI'99). ACM Press, 294-301.〕 premiered at the Association of Computing Machinery's 50th anniversary ACM Expo 1997. This demo inspired the Blue Eyes project at IBM Almaden, and coined the term Attention-based Groupware,〔Vertegaal, R., Velichkovsky, B., and Van der Veer, G. (1997). Catching the Eye: Management of Joint Attention in Cooperative Work. SIGCHI Bulletin (29)4.〕 now known as Attentive User Interfaces. During his PhD, Vertegaal demonstrated the power of eye contact in conversation, showing for the first time that speakers look more than listeners in multiparty conversations to indicate conversational attention, attributing the opposite pattern in dyadic conversations to the need to break prolonged eye contact, and showing that as much as 49% of the reason people speak is due to the presence of eye contact.〔Vertegaal, R., Slagter, R., Van der Veer, G. and Nijholt, A. (2001). Eye gaze patterns in conversations: there is more to conversational agents than meets the eyes. In Proceedings of the SIGCHI Conference on Human Factors in Computing Systems (CHI '01). ACM Press, pp. 301-308.〕
