SIGCHI Lifetime Practice Award


David Canfield Smith

David Canfield Smith received his PhD in computer science at Stanford University in 1975. His thesis contained two new ideas: icons and programming by demonstration. The first idea caught on and has been adopted worldwide. In 1976-83 he worked at Xerox Corporation, in the Systems Development Division. As one of the designers of the Xerox Star computer, he refined the idea of icons into a “desktop” metaphor for common office objects such as documents, folders, and wastebaskets. He also invented the concepts of dialog boxes for displaying and changing the properties of objects, and universal commands (move, copy, delete, undo, …) which applied to objects in all applications.

In 1998-2000 he worked at Stagecast Software. As one of the designers of Stagecast Creator, an educational software application for children, he cast his idea of programming by demonstration into terms acceptable to children. This allowed children to write their own video games, while teaching them the scientific method. With Allen Cypher and Alan Kay, he invented a visual representation for their programs which proved to be essential for children’s programming. It was well received by the educational community.

Outstanding Dissertation Award


Katta Spiel

Katta Spiel’s dissertation represents significant and original scientific achievements that can be summarised as: defining a new research area around technology experience and autistic children; providing a new methodology for participatory evaluation with children; and resulting in high quality and high volume peer-reviewed publications. Katta Spiel’s broader research agenda is around the participatory design and evaluation of technologies with marginalised groups; in the thesis work, this is with autistic children. Technology research with autistic children is often concerned with ‘solving’ functional problems, such as social skills, with parents, carers and educators as primary informants both for design and for evaluation. Katta Spiel’s work looks at playful technologies, prioritizing the children’s intrinsic interests, and researching ways in which their voices and perspectives can be brought into the technology design and evaluation process.

The thesis describes a series of iterative participatory engagements with eight autistic children, that each resulted in a bespoke innovative piece of technology that the children were involved in designing. The core contributions of the thesis arising through these deep long-term engagements include: an experience framework (conceptual framework) based on combining Actor-Network Theory and Critical Discourse Analysis to evaluate the experiences the children have with the technologies that were co-designed with them; and, in complement to this, a methodological toolkit for creatively enabling autistic children to participate in the evaluation process.

Spiel’s thesis work was conducted at TU Wien (University of Technology, Vienna) in Austria. Their work has been published in ToCHI, CHI, and PDC conferences (among others) and received several honorable mentions, two of which at CHI for core papers contributing to the thesis.



Paul Strohmeier

How can we design better ways of conveying information through haptics? Stepping outside on a cold winter morning, we have access to all kinds of information about the world. The chill of cold down our spine. The wind in our face. In comparison, most devices provide us with impoverished haptic feedback. For example, the buzzing of a smartphone notification is void of information. The buzzing is a symbol, a placeholder, merely pointing towards something else. In his dissertation “Shaping Material Experiences: Designing Vibrotactile Feedback for Active Perception” Paul Strohmeier explores using vibrotactile feedback to manipulate and augment the perceived material properties of objects users interact with. He shows that by tightly coupling tactile feedback to users’ actions, haptic experiences emerge which can be as intuitive and direct as sensing the crispness of the frozen ground beneath our feet.

Paul’s thesis improves how we might use haptics in HCI by demonstrating devices that can provide users with material experiences. These material experiences emerge, when minuscule movements by the user create proportional feedback, resulting in tight action-feedback loops in the low milliseconds range. Paul also presents a path towards further knowledge and rigor in designing novel experiences, by sketching a theory of embodied perception which synthesizes and contextualizes the results of his work. Specifically, for designing novel sensory experiences, HCI must also focus on small timescales and engage with timeframes below that of deliberate acts — for example, to manipulate the subtle, preconscious interactions between our fingers and materials. It is interaction in the low milliseconds range, bordering on the timescales at which biological signaling occurs, which leads to material experiences.

Paul’s dissertation was written at the University of Copenhagen, under the supervision of Kasper Hornbaeck. The ReFlex prototype and corresponding paper stem from Paul’s time at Queen’s University and were supervised by Roel Vertegaal.

Kristina Höök

Kristina Höök is a professor at the Royal Institute of Technology (KTH), Sweden, where she heads the Soma Design group.

Kristina has a long-standing reputation in the interaction design field, in particular she is known for her work on soma design: a process that allows designers to examine and improve on connections between sensation, feeling, emotion, subjective understanding and values. Soma design builds on pragmatics and in particular on somaesthetics combining soma as in our first person sensual experience of the world, with aesthetics as in deepening our knowledge of our sensory experiences to live a better life. Kristina recently published a book with MIT Press Designing with the body: somaesthetic interaction design aiming to establish soma design as a strand of interaction design more widely.

Kristina also works on epistemological questions for interaction design, proposing knowledge forms such as strong concepts and experiential qualities, to capture what she frames as intermediary knowledge forms.

Kristina received her PhD from Stockholm University and MSc from Uppsala University.



Kasper Hornbæk

Kasper Hornbæk is a Professor in Computer Science at the University of Copenhagen. He received his PhD from the University of Copenhagen in 2002. Hornbæk’s work has contributed to HCI in two important ways. First, he and his coauthors have created new models of usability and user experience. They have shown that different aspects of usability are orthogonal (and therefore should be measured independently); that we can measure how computer tools extend our bodies; and that meaning is an overlooked component of user experience. Second, Hornbæk and his collaborators have sought to develop fundamental concepts and methods in the HCI field. They have discussed the field-defining concept of interaction, analysed what it means that a user interface is subtle, and outlined the key types of problems addressed in HCI. Currently, Hornbæk works on body-based user interfaces and human-computer integration.



Meredith Ringel Morris

Meredith Ringel Morris is a Sr. Principal Researcher and Research Manager at Microsoft Research. She is an internationally-recognized leader in HCI, particularly in collaborative and social computing. Merrie is widely known as the founder of the field of collaborative web search; her SearchTogether system inspired numerous researchers in HCI and Information Retrieval to pursue work in this area. She subsequently co- developed a myriad of collaborative search prototypes and interaction techniques, aimed at supporting different search tasks, group configurations, and technologies. Her foundational studies of peoples’ collaborative searching habits and needs have informed the community’s understanding of search as a collaborative task. She was also the first to study the trend of friendsourced information seeking, wherein people use question-asking within social networks as an alternative to search engines; she contributed several articles describing and quantifying this phenomenon, as well as co-creating “socially embedded search engines,” an early type of chatbot that combined algorithmic search with friendsourcing. Additionally, Merrie is also widely known for her contributions to surface computing and gesture design: her dissertation introduced collaborative interaction techniques for the then-nascent field of surface computing, including cooperative gestures and identity-aware widgets, and her subsequent work as co-creator of the user-defined gesture-elicitation methodology has had broad impact in academia and industry, where it is frequently employed to design guessable gesture interfaces. More recently, she has emerged as a leader in accessibility, particularly accessible social media and accessible communication technologies.

Dr. Morris has served as the general chair for ACM’s CSCW conference and has previously served as Technical Program Chair of the CHI, CSCW, ASSETS, and ISS conferences. Dr. Morris is a past member of the TOCHI editorial board and of the CSCW and CHI steering committees. She has been recognized as one of Technology Review’s “35 under 35” for her work on collaborative web search and was named an ACM Distinguished Member for her contributions to HCI research. She is the author of more than 100 peer-reviewed research articles, many of which have been recognized with best paper awards, as well as Lasting Impact Awards from the UIST and ISS conferences. She is also an inventor on more than 20 U.S. patents, and her HCI innovations have influenced many of Microsoft’s products and services. In addition to her role at Microsoft, Dr. Morris is also an Affiliate Professor at the University of Washington in the School of Computer Science and Engineering and in the Information School. Dr. Morris earned her Sc.B. in computer science from Brown University, and her M.S. and Ph.D. in computer science from Stanford University.



Peter Wright

Peter Wright is Emeritus Professor of Social Computing at Newcastle University, UK. He has a background in applied psychology. In the late 80’s he joined the HCI Lab at the University of York where he developed cost-effective usability evaluation methods and with Andrew Monk, published Improving your Human-Computer Interface (Prentice Hall, 1993). In the 90’s he worked on safety critical interfaces and with Michael Harrison, published a portfolio of work about the evaluation of human-error tolerance in aircraft and air traffic control systems. Here, he came to recognise the importance of user experience in shaping computer use in social settings and with Mark Blythe, Andrew Monk, and Cees Overbeeke, he co-edited Funology: From usability to user enjoyment (Kluwer, 2003).

This led to his work on theory and methods for experience-centred design for which he is best known in the HCI community. This included three books co-authored with John McCarthy; Technology as Experience (MIT Press, 2004); Experience-Centred Design (Morgan Claypool, 2010); and Taking [A]Part: (MIT Press, 2015), along with a number of CHI publications which explore the aesthetics of interaction and participation. Most recently with Patrick Olivier and other colleagues at Newcastle University’s Open Lab, he has been developing the Digital Civics research programme which explores how human-centred design practice and digital technologies can support innovation and citizen participation in local democracy, education, health, social care, and social justice.
