Hiroshi Ishii is the Jerome B. Wiesner Professor of Media Arts and Sciences at the MIT Media Lab. After joining the Lab in October 1995, he founded the Tangible Media Group to make digital tangible by giving physical form to digital information and computation. Here, he pursues his visions of Tangible Bits (1997) and Radical Atoms (2012) that will transcend the Painted Bits of GUIs (Graphical User Interfaces), the current dominant paradigm of HCI (Human-Computer Interaction).

He is recognized as a founder of “Tangible User Interfaces (TUI),” a new research genre based on the CHI ’97 “Tangible Bits” paper presented with Brygg Ullmer in Atlanta, Georgia, which led to the spinoff ACM International Conference on Tangible, Embedded and Embodied Interaction (TEI) from 2007. In addition to academic conferences, “Tangible Bits” was exhibited at the NTT ICC (2000) in Tokyo, Japan, at the Ars Electronica Center (2001-2003) in Linz, Austria, and many other international arts and design venues. For his Tangible Bits work, he was awarded tenure from MIT in 2001, and elected to the CHI Academy in 2006.

In 2012, he presented his new vision of “Radical Atoms” to leap beyond “Tangible Bits” by assuming a hypothetical generation of materials that can change form and properties dynamically and computationally, becoming as reconfigurable as pixels on a GUI screen. His team’s Radical Atoms works, including Shape Displays and Programmable Materials, contributed to form the new stream of “Shape-Changing UI” research in the HCI community. His “Radical Atoms” vision was selected as the overarching theme of Ars Electronica Festival 2016, with the subtitle “The Alchemists of our Time.” Ishii’s team ran a 3 year long Radical Atoms Exhibition at the Ars Electronica Center, which has been extended to run through to the summer of 2019.

Ishii and his team have presented their visions of “Tangible Bits” and “Radical Atoms” at a variety of academic, design, and artistic venues (including ACM SIGCHI, ACM SIGGRAPH, Industrial Design Society of America, AIGA, Ars Electronica, ICC, Centre Pompidou, Victoria and Albert Museum, Cooper Hewitt Design Museum, Milan Design Week) emphasizing that the design of engaging and inspiring tangible interactions requires the rigor of both scientific and artistic review, encapsulated by his motto, “Be Artistic and Analytic. Be Poetic and Pragmatic.”

Prior to joining the MIT Media Lab, from 1988-1994 Ishii led the CSCW (Computer-Supported Cooperative Work) research group at NTT Human Interface Laboratories Japan, where he and his team invented the TeamWorkStation and ClearBoard. He received a B.E. degree in electronic engineering, and M.E. and Ph.D. degrees in computer engineering from Hokkaido University, Japan, in 1978, 1980 and 1992, respectively.

His greatest treasure is the email message he received from Dr. Mark Weiser in 1997 regarding his CHI ‘97 Tangible Bits paper which was on the verge of rejection.

SIGCHI Lifetime Practice Award


Daniel Rosenberg

Daniel Rosenberg is currently a UX consultant (rCDOUX.com) and an adjunct professor of HCI at San Jose State University.  He serves on the advisory board of the Interaction Design Foundation and edits the “Business of UX” Forum in ACM Interactions magazine.

Early in his career he introduced many UX methods and inventions that are now common practice. At Eastman Kodak he assembled the HF department’s first rapid prototyping lab, taught many workshops on this topic and coauthored the Prototyping chapter in the first Handbook of HCI (Elsevier 1988).   At a CHI 1988 special session he introduced the UX community to the concept of GUI look & feel as an integral part of corporate branding. During this period, he also coauthored (with W. Cushman) Human Factors in Product Design (Elsevier 1991), the first consumer product focused HF textbook.

As User Interface Architect for Ashton-Tate & Borland, Dan designed the first GUI Integrated Development Environment, defining the workspace style UX for programming tools. He invented Tabs as a UI mechanism along with several other innovative UI patterns while at Borland.  He also designed the first GUI administration UX for Oracle, again creating a pattern still commonly used today.

Dan’s contribution to UX management practice building large corporate UX departments began when he was hired in 1994 to establish the first UX team at Oracle, growing to more than 120 people during his 11-year leadership tenure. He was also the UX SVP at SAP for seven years.  During this 18-year period he conducted UX management workshops and served on numerous conference panels.  He also published many UX leadership articles, the most controversial of which was “The 7 myths of Usability ROI” (Interactions, Sept. 2004).

SIGCHI Lifetime Service Award


Bill Hefley

Bill Hefley, PhD, CCP, CDP, COP, is a clinical professor at the Naveen Jindal School of Management at The University of Texas at Dallas, where he serves as director of Business Analytics programs and as secretary of the faculty. He also is a founding director of ITSqc, LLC, a spinoff from Carnegie Mellon University. He previously was on the faculty at the University of Pittsburgh and Carnegie Mellon University, where he was a founding member of the Human-Computer Interaction Institute (HCII) and a member of the committee that developed the Master’s in HCI degree.  He has also been involved in curriculum efforts within SIGCHI and the Project Management Institute (PMI).

In 1990, Bill stepped in as the third editor-in-chief of the SIGCHI Bulletin. Shortly after becoming the SIGCHI Bulletin editor, Bill began investing a notable amount of his leadership talent in the effort to create a magazine for HCI/UX/UI professionals and academics, a forum beyond traditional journals. He served as SIGCHI’s adjunct chair for user interface magazine from 1991 to 1993, and he became SIGCHI’s vice chair for publications, which helped him to realize the initiative supported by many colleagues within SIGCHI to bring interactions to reality.  He served as founding editor for interactions, along with the late John Rheinfrank, through 1995. During that time, interactions went from a concept to a prototype and mock-up and into production, launching with its first issue in January 1994. Bill served as managing editor responsible for producing each issue in its first two years following launch. BIll set the direction and operating practice for the magazine, now, in its twenty-sixth year of publication, powerfully influential not only within SIGCHI, but also, as HCI has grown, more broadly within ACM and the computing profession.  interactions continues to be a forum where people from all continents can meet independent of their location, a media meeting space in the spirit of SIGCHI-sponsored conferences. In this way, Bill’s creation enabled, as well as stimulated, global participation in SIGCHI.

In 1993, Bill, with Dianne Murray and Wayne Gray, founded the Intelligent User Interface (IUI) conference series. Thereafter, Bill continued to be active in CHI conferences, leading panels and serving on conference committees. He also served on the SIGCHI Executive Committee and on the SIGCHI Conference Management Committee, which oversaw SIGCHI’s portfolio of conferences, for several years. He also has served as vice chair of ACM SIGCAS.

Bill has served in many roles and at many levels in SIGCHI and the ACM, and for that, the group always will be grateful. But it was in the creation and initial leadership of interactions that he made an indelible contribution, and it is primarily that significant contribution and service to SIGCHI now being acknowledged by the SIGCHI Lifetime Service Award.

Outstanding Dissertation Award


Chris Elsden

Chris Elsden’s dissertation (‘A Quantified Past: Fieldwork and Design for Remembering a Data-Driven Life’) is an exquisitely written exploration of the relationship people can have and want to have with self-tracking tools and how those tools might be designed to be more editable and more effective as longer-term resources for ‘documentary informatics’. The research entailed an enormous and wide set of readings, a very thorough user study and then a speculative design intervention related to weddings and their documentation.

Elsden’s thesis work included field studies informed by ethnographic methods, exploring how communities of people worked with ‘data’ to track aspects of their lives, through for example, activity logging in sports contexts or through diary keeping. Based on theses studies, alongside extensive readings on works by authors such as Bartlett, Bergson, and Middleton and Brown, Elsden constructed a philosophical engagement with human memory with substantial depth and nuance. Inspired by emerging Speculative Design techniques in design research communities, Elsden developed a new method for the HCI community called ‘Speculative Enactments’. This marries the strengths of critical and speculative design approaches that continue to gain traction and visibility in HCI, with the field-based approaches commonly applied in HCI contexts.

The thesis work resulted in a remarkable number of studies that were published at strong venues, such as CHI, DIS and the Human-Computer Interaction journal, but also more design-oriented conferences such as RtD (Research through Design).


Anna Feit

Anna Feit’s dissertation (‘Assignment Problems for Optimizing Text Input’) integrates empirical research, combinatorial optimization, and modeling to open new ways for designing text input methods that are fast, ergonomic and learnable. While researchers at the forefront of HCI thought 10 finger typing was an intractable problem to quantitative optimization, Anna Feit took a much more optimistic, daring and simple approach using big data processing. She applies the same conceptual framework in developing three novel text input applications: 1. Text input with multi-finger gestures in mid-air; 2. transferring the skill of pianists by enabling text input on the long piano keyboard; and 3. optimal input of special characters on the physical keyboard. Furthermore, Feit published two large datasets of everyday typing behavior that are unique in size and the data they capture: 1) an online study of transcription typing with over 169,000 users; and 2) motion capture data, eye tracking data and reference videos of 30 everyday typists. Her conceptual and empirical work challenges many conventional wisdoms of the field. For example, her large dataset-based-observation confirms what many intuitively felt about rigid 10 finger touch typing taught in classical typing lessons. As it turns out, the high performers in her data often do not use full fledged, rigid touch-typing.

Overall, her work is a success story for the positive impact of HCI research on real world problems. Amazingly, Anna Feit was able to work with the French standardization organization, applying her principled methods to develop France’s new keyboard standard which will soon be adopted in France – potentially impacting the life of all of French speaking computer users.

Feit’s thesis work was done at Aalto University School of Electrical Engineering, Helsinki, Finland.  Feit has published her work in ToCHI, as well as the CHI and DIS conferences, receiving honorable mentions for two of her papers at CHI.


Robert Xiao

Robert Xiao’s dissertation (‘On-World Computing Enabling Interaction on Everyday Surfaces’) introduces on-world computing, an interaction paradigm in which touch-sensitive interactive content is projected out onto surfaces in the natural world. This is both very challenging and very timely since these solutions have the potential to take the familiar touch interactions from the smartphones of today and apply them to a wide variety of Augmented Reality scenarios of the future. One of the main contributions lies in the technical solution for tracking fingertip/touch using depth cameras. Xiao introduces several best-in-class algorithms for this task which can be used by others off the bat. Apart from these input solutions, the thesis work also covers design aspects of interaction techniques and capabilities, culminating in fully integrated, usable prototype systems. Here we see a combination of really important advances on a technical level with the understanding of the requirements and the combination into a complete system of use to end-users. The resulting systems are technically very strong and show great skill in user interface technologies.

Xiao’s thesis work was done at the Human-Computer Interaction Institute at Carnegie Mellon University. Xiao has already published 25 papers and has attracted more than 900 citations. Most of his publications are at top venues of HCI: 8 CHI and 6 at UIST. Two of his papers have received Best Paper awards.

Batya Friedman

Batya Friedman is a professor in the Information School at the University of Washington where she codirects the Value Sensitive Design Lab and the Tech Policy Lab. In 2012 she was awarded the ACM SIGCHI Social Impact Award.

Batya pioneered value sensitive design (VSD), an approach to account for human values in the design of technology. First developed in human-computer interaction, VSD has since been used in architecture, civil engineering, computational linguistics, computer security, energy, human-robotic interaction, information management, legal theory, moral philosophy, science and technology studies, and transportation. Batya has worked on technologies and values in a wide range of systems, from security for implantable medical devices to informed consent for cookies and web browsers, reputation in knowledge base systems, privacy in mobile technology, and equitable representation in large-scale computer simulation for land use and transportation planning. She is currently working on multi-lifespan design—generating design knowledge for envisioning and building information systems to support sociotechnical solutions as they unfold over longer periods of time, on the order of 50 or 100 years.

To bring VSD into human-computer interaction, design and tech policy research and practice, Batya has developed practical methods and toolkits. Among these, Envisioning Cards help technologists consider stakeholders, values, time, and pervasive uptake in their technical work; Security Cards, with a focus on threat analysis, help to develop a security mindset; and Diverse Voices aims to create more inclusive tech policy. Her new book with David Hendry, Value Sensitive Design: Shaping Technology with Moral Imagination (2019) is published by MIT Press.

Batya is also a stone sculptor and mixed media artist. She received her BA and PhD from the University of California at Berkeley.
