Finding design qualities in a tangible programming space

We reflect upon the process of developing a tangible space for childrens collaborative construction of screen-based systems. As in all design work, the design process involved continual refinements of initial ideas and their practical realisation. We discuss how some widely held assumptions often put forward with tangible interfaces were given up in favour of reaching overall goals of interaction. In particular our design involved a shift from a focus on persistent representation and readability of tangible code structures, to instead focus on achieving reusability of programming resources. On a general level, our results illustrate a view on tangibles as resources for action instead of only as alternative forms of data representation. Importantly, this view includes action directed towards the computer as well as off-line socially oriented action conducted with the tangible artefacts.

Towards a new set of ideals: consequences of the practice turn in tangible interaction

The practice-oriented turn in social sciences has implied a series of fundamental consequences and design challenges for HCI in general, and particularly in tangible interaction research. This could be interpreted as a move away from scientific ideals based on a modernist tradition, reflected in four contemporary themes in tangible interaction research. The first theme concerns a shift from an information centric to an action centric perspective on interaction. The second concerns a broadened focus from studying properties of the system, to instead aim at supporting qualities of the activity of using a system. The third concerns the general shift towards supporting sharable use, rather than primarily individual use settings. The last theme concerns the shift towards multiple and subjective interpretation of how to use new technological artefacts. We discuss how these themes are grounded in theoretical as well as more concrete technical developments in the area of tangible computing.

Snot, Sweat, Pain, Mud, and Snow: Performance and Experience in the Use of Sports Watches

We have conducted interviews with ten elite and recreational athletes to understand their experiences and engagement with endurance sport and personal and wearable sports technology. The athletes emphasized the experiential aspects of doing sports and the notion of feeling was repeatedly used to talk about their activities. Technology played both an instrumental role in measuring performance and feeding bio-data back to them, and an experiential role in supporting and enhancing the sport experience. To guide further interaction design research in the sports domain, we suggest two interrelated ways of looking at sports performances and experiences, firstly through the notion of a measured sense of performance, and secondly as a lived-sense of performance.

Design qualities for whole body interaction: learning from golf, skateboarding and BodyBugging

What is it that is makes swinging a club to hit a ball so captivating and fun that people spend their whole lives perfecting that one movement? In this paper we present how we, rather than to invent something off-line in a lab, have returned to the real world to get inspiration and studied full body movement activities with non-digital artefacts that have track records of ensnaring and hooking practitioners for a life time, golf and skateboarding. We have also looked at a new interactive movement device called the BodyBug. We explore how the skilled use of the artefacts puts people in contact with and let them experience the world in an essentially new way. We identify and present 8 design qualities for Whole Body Interaction, based on peoples performances in these activities. The interdependency between user, artefact and physical environment was a primary driving forces behind rich, sustained and graceful interaction with the artefacts.

Beyond representations : towards an action centric perspective on tangible interaction

In the light of theoretical as well as concrete technical development, we discuss a conceptual shift from an information-centric to an action-centric perspective on tangible interactive technology. We explicitly emphasise the qualities of shareable use, and the importance of designing tangibles that allow for meaningful manipulation and control of the digital material. This involves a broadened focus from studying properties of the interface, to instead aim for qualities of the activity of using a system, a general tendency towards designing for social and sharable use settings and an increased openness towards multiple and subjective interpretations. An effect of this is that tangibles are not designed as representations of data, but as resources for action. We discuss four ways that tangible artefacts work as resources for action: (1) for physical manipulation; (2) for referential, social and contextually oriented action; (3) for perception and sensory experience; (4) for digitally mediated action.

“Looking At the Computer but Doing It On Land”: Children’s Interactions in a Tangible Programming Space

We present a tangible programming space designed for children’s collaborative construction of screen-based interactive systems. The design is based on three goals for interaction and activity: supporting co-located collaborative activity, screen-based execution, and what we call behaviour-based programming. Further, we analyse the interactions within a group of 10 year olds who used the system to create a live fantasy world together. The results show how the tangible resources shaped the activity of programming so that bodily actions and positioning became prominent. This is conceptualized through the notion of embodied programming, which highlights how programming activity must be understood through its interlinking to external resources and context.

Revisiting the jacquard loom: threads of history and current patterns in HCI

In the recent developments of human computer interaction, one central challenge has been to find and to explore alternatives to the legacy of the desktop computer paradigm for interaction design. To investigate this issue further we have conducted an analysis on a fascinating piece of machinery often referred to as one of the predecessors of the modern day computer, the Jacquard loom. In analysing the Jacquard loom we look at qualities in design and interaction from some different perspectives: how historical tools, crafts, and practices can inform interaction design, the role of physicality, materiality, and full-body interaction in order to rethink some current conceptions of interaction and design of computational devices.

The lega: a device for leaving and finding tactile traces

This paper describes experiences from development and deployment of the Lega, a hand held device for physical sharing of experiences during an art exhibition. Touching and moving the device in different ways creates a tactile trace that can be experienced by others through their own device. The system was successfully deployed at an art exhibition for two months where user studies were performed. Here we present some general observations regarding the systems performance and discuss issues that we encountered.

HCI and sports

Sport is an area in which the number of available computing devices is growing rapidly. However, HCI has so far devoted rather little attention to the sports domain. This workshop aims to form a community around sports by gathering existing activity in the HCI domain, thus starting a discussion on what HCI can contribute to the sports domain, as well as what HCI can gain from studying sports.

Runright: real-time visual and audio feedback on running

RunRight is a system that gives two different kinds of feedback for runners. First, it creates a visualization of the running movement based on acceleration in vertical and horizontal direction. Second it gives audio feedback on the rhythm. These two types of feedback are valuable when exploring how to design technology that supports athletes in learning how a desired movement should feel.
