Abstract. Large public displays are becoming a ubiquitous resource in the urban environment. Interconnected over the Internet these hitherto isolated "ad displays" could become a novel and powerful communication medium -networked public displays. One example for such a novel type of communication is their use as community tools. Scattered across the urban landscape and equipped with additional sensors, such as cameras, they provide the opportunity for local community members to take images of themselves and leave their "mark" in the setting, e.g., on their way to school, work, or meeting with friends. In order to understand the potential of posting situated snapshots on networked public displays in the context of place-based communities we designed and developed the Moment Machine -a networked public display application that allows one-click photo capture. In this paper we report on identified opportunities and challenges emerging from 6 user trials in the wild at 2 locations.

“…A larger setup of the system in an open environment, such as a shopping mall or outdoors [24] requires robust hardware that can cope with many users and difficult lighting conditions such as sunset. The choice of hardware to capture the users is a defining element of the reliability of the final system.…”

“…Multi-touch interaction techniques have become widely available recently, being used for instance in table top systems such as Microsoft's Surface [30] projection-based systems such as CityWall [24], desktop systems such as HP's TouchSmart series as well as in several mobile devices, in particular smartphones such as the Google Nexus and, of course, the iPhone. The introduction of multi-touch interaction techniques has probably been the most important change to user input since the introduction of the mouse.…”

We present a novel technique implementing barehanded interaction with virtual 3D content by employing a time-of-flight camera. The system improves on existing 3D multi-touch systems by working regardless of lighting conditions and supplying a working volume large enough for multiple users. Previous systems were limited either by environmental requirements, working volume, or computational resources necessary for realtime operation. By employing a time-of-flight camera, the system is capable of reliably recognizing gestures at the finger level in real-time at more than 50 fps with commodity computer hardware using our newly developed precision hand and finger-tracking algorithm. Building on this algorithm, the system performs gesture recognition with simple constraint modeling over statistical aggregations of the hand appearances in a working volume of more than 8 cubic meters. Two iterations of user tests were performed on a prototype system, demonstrating the feasibility and usability of the approach as well as providing first insights regarding the acceptance of true barehanded touch-based 3D interaction. INTRODUCTIONMulti-touch interaction techniques have become widely available recently, being used for instance in table top systems such as Microsoft's Surface [30] projection-based systems such as CityWall [24], desktop systems such as HP's TouchSmart series as well as in several mobile devices, in particular smartphones such as the Google Nexus and, of course, the iPhone. The introduction of multi-touch interaction techniques has probably been the most important change to user input since the introduction of the mouse.To date, multi-touch interaction typically is surface based. Selection of objects is required before actually manipulating them by touching the corresponding surface with the hands.Freehand multi-touch has been explored within various approaches, e.g. Oblong's g-speak 1 , after initially having been introduced in the popular Hollywood movie "Minority Report". They usually depended heavily on hand-worn gloves, markers, wrists, or other input devices, and typically did not achieve the intuitiveness, simplicity and efficiency of surface (2D) based multi-touch techniques 2 . In contrast to those approaches, the goal of our approach was to use barehanded interaction as a replacement for surface based interaction.Only a vision-based approach will allow for freehand and barehanded 3D multi-touch interaction. The system must also provide sufficient solutions for the following four steps: detection of hand position without prior knowledge of existence; for each appearance determine pose from image cues; track appearances over time; recognize gestures based on their trajectory and pose information. Various approaches exist to solve all four problems, each featuring different advantages and disadvantages.Barehanded 3D interaction has recently been presented by Mygestyk 3 and provides the basis for Microsoft's Kinect interface for Xbox 360 4 . However, these approaches are limited either to a sing...

Their research is technically similar to this research, but we aim at content connections rather than direct interactions among participants.…”

Abstract. In this paper, we propose a framework for content collection and connection enabled by public large screens and mobile phones. Making people express their stories will encourage their active attitudes toward information management. With the proposed framework, we aim to overcome difficulties on managing flooding information. We applied the framework on two practice oriented systems and held workshops using them.
