The rapid development of handheld devices is driving the development of new interaction styles. This paper examines one such technique: using hand motions to control a menu system. Previous research on this topic deals with systems which rely heavily on graphical feedback, a disadvantage in many mobile scenarios. Inspired by marking menus, our system is designed to be used "eyes-free" and based on making relatively large scale rotational strokes. We describe the system and an initial evaluation in detail. The results indicate that its performance is comparable to previous motion menu systems, but that this can be attained without visual feedback. This represents a substantial benefit.

When authoring in visual storytelling environments, children are often limited to use characters and props available in libraries or have to create their own using software. We present a novel alternative in the early design and implementation of Vuelta, a tool for creating animated characters and props using real-world objects. Vuelta authors can create animations for real-world characters and props by capturing animation frames using a high-definition camera. Each frame is captured from many directions enabling the characters and props to be positioned in any direction. We use an image difference algorithm to extract the characters and props from the frames. Our setup is designed to support creativity by enabling authors to use objects of their choice that they may create with their own hands and by not putting limits on the types of animations that may be created. Vuelta is also designed to support collaboration by enabling more than one author to participate in the process. The next steps in our development of Vuelta include working with children to design a tool to edit the animations, as well as integrating Vuelta with a storytelling environment we are developing.

It is often difficult for practising interaction designers to engage with real end-users because of the competing economic pressures on projects. Preliminary research with end-users (a particularly rich source of information) may be squeezed in favour of more tangible, later-stage project deliverables. This case study paper presents a pragmatic approach to getting closer to end-users by briefing project stakeholders to think as surrogate users within managed 90 to 120 minute-long focus groups. It concludes with an evaluation of the approach in terms of the experiences of the research participants and its merits in terms of project delivery and outcomes. It finds that the method described is particularly useful in multi-stakeholder projects and provides a rich design brief with clear, agreed, user-centred design goals.

Within the HCI community, there is a growing interest in how technology is used and appropriated outside the workplace. In this paper, we present preliminary findings of how large displays, projection systems, and presentation software are used in American megachurches to support religious practice. These findings are based on ten visits to church services by the study.s authors. We describe how large display technology augments and replaces certain church traditions, and finish by discussing issues related to the design for church environments that are highlighted by this use of technology.

Home networking continues to expand into a collection of computers and networked devices that are becoming more complex to setup and manage. Research indicated that new techniques were needed to help people set up a secure home network. The techniques should satisfy the expectations of advanced users, without requiring technical knowledge on the part of novice users. A central design theme influenced the software solution: If a networking expert was advising a user on how to set up, configure, and secure a home network, what would this person tell the user to do?. In this case study, insights about creating a new home networking program to solve the challenges are discussed. Results indicated animations, good default settings and a network map increased the user success rate for network setup.

This paper explains an implementation of new media "SuiPo," or Suica Poster, which uses a combination of IC card ticket "Suica" and Internet accessible mobile phone. Customers can get e-mail information by touching their IC card ticket on the reader located near the poster. Two pilot tests are conducted before the service has begun. The first test revealed that many people preferred the interactive poster but the registration process was complicated. The second test was conducted after improving the registration process. The lessons learned through two pilot tests are that in addition to the easier registration process, the increased popularity of two dimensional barcode reader in mobile phone has lowered the barrier of registration process. The SuiPo has been introduced in July 31st, 2006 and started service at Shinjuku Station and Tokyo Station. We hope the implementation would change customers' perception of Suica not only as a ticket or e-money but also as an information tool.

In this paper we present the concept of an isovist, derived from the architectural literature, and describe how isovists can help HCI researchers understand visibility in a physical environment. An isovist is defined as the set of all points visible in all directions from a given vantage point in space. The overlap in isovists from two or more locations can be used to assess reciprocal visibility and thereby assist in the placement of large displays for public or shared use. We illustrate the value of isovists for HCI research using field data from two OR suites in two major urban hospitals. First, we show how patterns of interaction between anesthesiologists and nurses in each of two OR suites are associated with quantity of isovist overlap. Then, we show how an isovist analysis can be used to determine a better placement for the shared display in one of the OR suites to enhance coordination between groups.

Augmented video streams display information within the context of the physical environment. In contrast to Augmented Reality, they do not require special equipment, they can support many users and are location-independent. In this paper we are exploring the potentials of augmented video streams for remote participation. We present our design considerations for remote participation user interfaces, briefly describe their development and explain the design of three different application scenarios: watching a pervasive game, observing the quality of a production process and exploring interactive science exhibits. The paper also discusses how to develop high quality augmented video streams along with which information and control options are required in order to obtain a viable remote participation interface.

We seek to motivate drivers who regularly use web-based local and mapping services and have access to viable alternative transit methods - such as public transportation, carpooling, walking or bicycling - to use these alternatives instead of driving alone. altVerto works with users' existing habits to intervene during trip planning, and then sustains long-term positive behavior through progress tracking and community-building around alternatives to driving. Our study investigates how computer-mediated intervention at decision making moments and online transit-related community motivates and sustains the use of alternative transit methods.

This paper describes a telepresence device called Porta-Person. This is the first project in a larger initiative known as the Connected Conference Room, which aims to improve the user experience for remote people connected to meetings taking place in conference rooms. The Porta-Person is designed to enhance a sense of social presence for remote meeting participants. It does this by providing a high-fidelity audio connection and a remotely controlled telepresence display with video or animation.
