Interaction platform-orientated perspective in designing novel applications

The lack of HCI offerings in the invention of novel software applications and the bias of design knowledge towards desktop GUI make it difficult for us to design for novel scenarios and applications that leverage emerging computational technologies. These include new media platforms such as mobiles, interactive TV, tabletops and large multi-touch walls on which many of our future applications will operate. We argue that novel application design should come not from user-centred requirements engineering as in developing a conventional application, but from understanding the interaction characteristics of the new platforms. Ensuring general usability for a particular interaction platform without rigorously specifying envisaged usage contexts helps us to design an artifact that does not restrict the possible application contexts and yet is usable enough to help brainstorm its more exact place for future exploitation

HCITools:strategies and best practices for designing, evaluating and sharing technical HCI toolkits

Over the years, toolkits have been designed to facilitate the rapid prototyping of novel designs for graphical user interfaces, physical computing, fabrication, tangible interfaces and ubiquitous computing. However, although evaluation methods for HCI are widely available, particular techniques and approaches to evaluate technical toolkit research are less well developed. Moreover, it is unclear what kind of contribution and impact technical toolkits can bring to the larger HCI community. In this workshop we aim to bring together leading researchers in the field to discuss challenges and opportunities to develop new methods and approaches to design, evaluate, disseminate and share toolkits. Furthermore, we will discuss the technical, methodological and enabling role of toolkits for HCI research

Evaluating programming systems design

Research on programming systems design needs to consider a wide range of aspects in their full complexity. This includes user interaction, implementation, interoperability but also the sustainability of its ecosystem and wider societal impact. Established methods of evaluation, such as formal proofs or user studies, impose a reductionist view that makes it difficult to see programming systems in their full complexity and, consequently, force researchers to adopt simplistic perspectives. This paper asks whether we can create more amenable methods of evaluation derived from existing informal practices such as multimedia essays, demos, and interactive tutorials. These popular forms incorporate recorded or scaffolded interaction, often embedded in a text that guides the reader. Can we augment such forms with structure and guidelines to obtain methods of evaluation suitable for peer review? We do not answer this question, but merely seek to identify some of the problems and instigate a community discussion. In that spirit we propose to hold a panel session at the conference

Cedar Studio: an IDE supporting adaptive model-driven user interfaces for enterprise applications

Support tools are necessary for the adoption of model-driven engineering of adaptive user interfaces (UI). Enterprise applications in particular, require a tool that could be used by developers as well as I.T. personnel during all the development and post-development phases. An IDE that supports adaptive model-driven enterprise UIs could further promote the adoption of this approach. This paper describes Cedar Studio, our IDE for building adaptive model-driven UIs based on the CEDAR reference architecture for adaptive UIs. This IDE provides visual design and code editing tools for UI models and adaptive behavior. It is evaluated conceptually using a set of criteria from the literature and applied practically by devising example adaptive enterprise user interfaces

Using Software Metrics in the Evaluation of a Conceptual Component Model

International audienceEvery interactive system has a functional part and an interactive part. However the software engineering and the human-computer-interaction communities work separately in terms of methods, models and tools, which induces a work overhead for integrating the results of these efforts, as well as increased inconsistency risks. We endeavour to treat this problem by proposing a design method, which couples the functional kernel and the interaction design. In particular, this method proposes a specific way of structuring the interaction and the business spaces. The structure is based on components called Symphony Objects. In this article, we attempt to evaluate the technical aspect of a Symphony Object model issued from the method by measuring its implementations with software metrics

Software support for multitouch interaction: the end-user programming perspective

Empowering users with tools for developing multitouch interaction is a promising step toward the materialization of ubiquitous computing. This survey frames the state of the art of existing multitouch software development tools from an end-user programming perspective.This research has been partially funded by the EUFP7 project meSch (grant agreement 600851 and CREAx grant (Spanish Ministry of Economy and Competitivity TIN2014-56534-R

Shared Substance: Developing Flexible Multi-Surface Applications

International audienceThis paper presents a novel middleware for developing flexible interactive multi-surface applications. Using a scenario-based approach, we identify the requirements for this type of applications. We then introduce Substance, a data-oriented framework that decouples functionality from data, and Shared Substance, a middleware implemented in Substance that provides powerful sharing abstractions. We describe our implementation of two applications with Shared Substance and discuss the insights gained from these experiments. Our finding is that the combination of a data- oriented programming model with middleware support for sharing data and functionality provides a flexible, robust solution with low viscosity at both design-time and run-time

Language and system support for interaction

International audienceInteraction frameworks are the norm for prototyping, implementing and sharing user interfaces and interaction techniques. However, they often lack the flexibility to easily implement new kinds of interfaces and interaction techniques, since they were basically designed for implementing standard and normalized WIMP user interfaces. This forces programmers to rely on " hacking " in order to experiment with functional prototypes, and could drastically limit the range of scenarios where these prototypes will work. In my PhD, I study the interplay between people designing interaction techniques, and their software frameworks. My goal is to identify a number of fundamental features and requirements that programming languages and systems should support, in order to improve the flexibility of interaction frameworks for programming advanced interaction techniques
