In this paper, we map out the CoCe design space - a design space for co-located collaborative games that use multi-display composition. The design space grew out of the analysis of game instances based on the 4in1 concept. First, we did a horizontal analysis of 16 game instances with 31 corresponding gameplay design patterns (GDP), followed by a vertical analysis of 89 GDPs occurring in the description of the GDP Cooperation. Through inductive analysis, we have identified four perspectives with corresponding dimensions that span the CoCe design space. By applying the CoCe design space with game instances, we illustrate how it can be used both as an analytic tool for analysis of games and also as a generative tool in the design or re-design of cooperative games that use multi-display composition.

In this paper, we discuss the applicability of using design patterns to enhance the participation of children in the design process. This is illustrated by a study in which gameplay design patterns have been used to evaluate and re-design a collaborative co-located game focused on training collaboration skills in a special education context. The results show that patterns helped as a way of focusing the analysis of observations, as tools for noting suggestions for change, supported the children's involvement in co-design activities, worked as an extendable collection of intermediate-level knowledge elements, and that patterns functioned as a way to introduce a common vocabulary. The contribution of this paper is a number of opportunities and challenges for working with gameplay design patterns with children.

Motivation studies on running are often focused on how to convince non-runners to run, mainly through designing for extrinsic motivations such as health concerns or external reward systems. In contrast, we conducted a structured inquiry into understanding how to design technology for those whom are already committed to running and participate in organized races. Through interviews, focus groups, ethnographic observation, questionnaires, and design-based research over the course of two years, we investigated the needs of the advanced amateur runner community. An analysis of the gathered data led to five design themes -- Festival, Competition, Practicalities, Togetherness, and Support -- to inform future runner motivation technology. While flow theory appears to be a convenient tool to understand support during a race, we observed a number of other factors that need to be considered. Through combining the themes with previous research, we conclude by presenting nine guidelines for designing technology for this domain.

This paper explores remote cheering during amateur races through a formative design inquiry. Friends and family of advanced amateur runners are part of their running experience. Runners rely on support during the race day and it is usually provided in the form of co-located cheers. RUFUS -- a prototype remote ambient runner support system -- was developed. The system enables supporters to send three types of signals to runners during a race and runners can send signals back to supporters. Input from supporters is sent through a webpage and received by runners through a device designed to lower distraction. An in situ study was conducted to evaluate the prototype during an organized race. Results show that two-way communication between runners and supporters was achieved. We also found that our system reflected varying user needs correctly. Runners and supporters reported increased motivation and enhanced race experience through feeling connected.

This paper introduces Tisch, an application running on the Microsoft Surface that provides computer support for board- and role-playing games. Based on the ideas of tangible and tabletop interfaces, Tisch was developed to explore how technology can support and enhance tabletop gaming activities without becoming a hindrance or removing the players' agency over the rules. Through doing so, Tisch allows players to behave in their accustomed manner, including having unrestricted social interactions and using whatever rules they wish to whatever degree they wish. This is proposed as a solution to harnessing the advantages that computers offer analog games through both offloading unwanted tasks and enhancing immersion.

Games can support many types of activities. This paper explores one of these, pottering, the placid but yet focused activity of arranging and rearranging things, taking care of them, "sorting them out". Five games which support pottering are analyzed using gameplay design patterns to show how game mechanics can give rise to the activity. As a result, six patterns especially linked to pottering are presented in greater detail. Moreover, the idea of viewing games as artifacts that can support several, sometimes overlapping, activities, is being explored and discussed.

This paper describes hierarchical Flip Zooming, a focus+context visualization technique for hierarchical information sets. It allows for independent focus+context views at each node of the hierarchy and enables parallel exploration of different branches of the hierarchy. Visualization, navigation and interaction in the Flip Zooming technique is described as well as how the technique fits into existing models of information visualization. Examples of applications using the technique are given.

We describe WEST, a WEb browser for Small Terminals, that aims to solve some of the problems associated with accessing web pages on hand-held devices. Through a novel combination of text reduction and focus+context visualization, users can access web pages from a very limited display environment, since the system will provide an overview of the contents of a web page even when it is too large to be displayed in its entirety. To make maximum use of the limited resources available on a typical hand-held terminal, much of the most demanding work is done by a proxy server, allowing the terminal to concentrate on the task of providing responsive user interaction. The system makes use of some interaction concepts reminiscent of those defined in the Wireless Application Protocol (WAP), making it possible to utilize the techniques described here for WAP-compliant devices and services that may become available in the near future.
