Abstract

In this paper we propose a novel way of supporting occasional meetings that take place in unfamiliar public places, which promotes lightweight, visible and fluid collaboration. Our central idea is that the sharing and exchange of information occurs across public surfaces that users can easily access and interact with. To this end, we designed and implemented Dynamo, a communal multi-user interactive surface. The surface supports the cooperative sharing and exchange of a wide range of media that can be brought to ...

Abstract

Software today does not help us partition our digital worlds effectively. We do it ourselves. This field study of users of multiple monitors examines how people with a lot of display space organize and arrange information. Their second monitors are not generally used as extra workspace, they are used for secondary activities related to principal tasks, for peripheral awareness of information that is not the main focus, and for easy access to resources. The second monitor improves efficiency in... ...

Abstract

We explore the idea of using vision-based hand tracking over a constrained tabletop surface area to perform multifinger and whole-hand gestural interactions with large displays from a distance. We develop bimanual techniques to support a variety of asymmetric and symmetric interactions, including fast targeting and navigation to all parts of a large display from the comfort of a desk and chair, as well as techniques that exploit the ability of the vision-based hand tracking system to provide... ...

Abstract

Recent HCI research shows strong interest in task management systems (e.g. [19, 27]) that support the multi-tasked nature of information work [13]. These systems either require users to manually create and maintain task representations or they depend on explicit user cues to guide the creation and maintenance process. To access and use the task representations in these systems, users must also specify their current task. This interaction overhead inhibits the adoption of these systems. In this paper, we present a novel ...

Abstract

A key constraint on the effectiveness of window-based human-computer interfaces is that the display screen is too small for many applications. This results in “window thrashing,” in which the user must expend considerable effort to keep desired windows visible. Rooms is a window manager that overcomes small screen size by exploiting the statistics of window access, dividing the user's workspace into a suite of virtual workspaces with transitions among them. Mechanisms are described for solving the problems of navigation ...

Abstract

This paper describes systems that examine and react to an individual's changing context. Such systems can promote and mediate people's interactions with devices, computers, and other people, and they can help navigate unfamiliar places. We believe that a limited amount of information covering a person's proximate environment is most important for this form of computing since the interesting part of the world around us is what we can see, hear, and touch. In this paper we define context-aware... ...

Abstract

Using body sensor networks (BSN) in critical clinical settings like emergency units in hospitals or in accidents requires that such a network can be deployed, configured, and started in a fast and easy way, while maintaining trust in the network. In this paper we present a novel approach called BLIG (Blinking Led Indicated Grouping) for easy deployment of BSNs on patients in critical situations, including mechanisms for uniquely identifying and grouping sensor nodes belonging to a patient in a secure and ...

Abstract

Collaboration, coordination, and communication are crucial in maintaining an efficient and smooth flow of work in an operating ward. This coordination, however, often comes at a high price in terms of unsuccessfully trying to get hold of people, disturbing telephone calls, looking for people, and unnecessary stress. To accommodate this situation and to increase the quality of work in operating wards, we have designed a set of pervasive computer systems which supports what we call context-mediated communication and awareness. These systems ...

Abstract

Productive collaboration in a multiple-device environment (MDE) requires an effective interface for efficiently managing applications among devices. Though many interfaces exist, there is little empirical understanding of how they affect collaboration. This paper reports results from a user study comparing how well three classes of interfaces; textual, map, and iconic, support application management during realistic, collaborative activities in an MDE. From empirical results, observations, and an analysis of how users interacted with each interface, we produced a set of design lessons ...

The system facilitates privacy by performing local computation, it supports heterogeneous devices and it provides a platform and initial architecture for exploring the use of sensors with elderly people in the Information Technology for Assisted Living and Home project. The goal of this project is to ...

Abstract

Building capture and access (C&A) applications for use in the operation theatre differs greatly from C&A applications built to support other settings e.g. meeting rooms or classrooms. Based on field studies of surgical operations, this paper explores how to design C&A applications for the operation theatre. Based on the findings from our field work, we have built the ActiveTheatre, a C&A prototype. ActiveTheatre is built to support collaboration in and around the operating theatre, to capture events instead of automatically capturing ...

Abstract

Situation awareness, and how systems can be designed to support it appropriately, have been a focus of study in dynamic, safety critical contexts such as aviation. The work reported here extends the study of situation awareness into the domain of emergency medical dispatch (EMD). The study was conducted in one of the largest ambulance services in the world. In this study, we encountered development and exploitation of situation awareness, particularly among the more senior EMD operators called allocators. In this paper ...

Abstract

Character segmentation has long been a critical area of the OCR process. The higher recognition rates for isolated characters vs. those obtained for words and connected character strings well illustrate this fact. A good part of recent progress in reading unconstrained printed and written text may be ascribed to more insightful handling of segmentation. This paper provides a review of these advances. The aim is to provide an appreciation for the range of techniques that have been developed, rather than to ...

Abstract

This paper uses a case study of collaborative work practices within the radiology department of a hospital, for examining the usefulness of spatial approaches to collaboration. It takes a socio-political perspective on understanding the shaping effects of spatial arrangements on work practices, and seeks to identify some of the key CSCW issues that can be addressed in spatial terms. We analyse the spatial settings or layers (physical, digital and auditory) within which work takes place, and the qualities of connections between ...

Abstract

The authors deployed a distributed system containing a location-tracking system, a context-awareness system, wall-sized displays, and mobile phones in a Danish hospital's operating ward. This article presents the lessons they learned from deploying these pervasive computing technologies and a checklist of questions for researchers to consider relating to hardware, software, and organizational issues when moving pervasive systems out of the laboratory. This article is part of a special issue on Real-World Deployments. ...

Abstract

In mobile devices, such as mobile phones and PDAs, an integrated camera can be used to interact with the device in new ways. In this paper we introduce the term mixed interaction space and argue that the possibility of using mixed interaction spaces is what distinguishes camera-based interaction from other types of sensor-based interaction on mobile devices. We present our implemented applications, and related work that use mixed interaction spaces. Based on this we address how mixed interaction spaces can have ...

Abstract

Ethnography has become a staple feature of IT research over the last twenty years, shaping our understanding of the social character of computing systems and informing their design in a wide variety of settings. The emergence of ubiquitous computing raises new challenges for ethnography however, distributing interaction across a burgeoning array of small, mobile devices and online environments which exploit invisible sensing systems. Understanding interaction requires ethnographers to reconcile interactions that are, for example, distributed across devices on the street with ...

Abstract

Public spaces are changing from being ungoverned places for interaction to be more formalized, controlled, less interactive, and designed places aimed at fulfilling a purpose. Simultaneously, new personal mobile technology aims at providing private individual spaces in the public domain. In this paper we explore the implications of interacting in public space and how technology can be rethought to not only act as personal devices, but be the tool to reclaim the right and possibility to interact in public spaces. We ...

Abstract

Chronic diseases, endemic in the rapidly aging population, are stretching the capacity of healthcare resources. Increasingly, individuals need to adopt proactive health attitudes and contribute to the management of their own health. We investigate existing diabetes self-management practices and ways in which reflection on prior actions impacts future lifestyle choices. The findings suggest that individuals generate and evaluate hypotheses regarding health implications of their actions. Thus, health-monitoring applications can assist individuals in making educated choices by facilitating discovery of correlations between ...

Abstract

We describe a user study of a large multi-user interactive surface deployed for an initial period within a real world setting. The surface was designed to enable the sharing and exchange of a wide variety of digital media. The setting for the study was the common room of a high school where students come together to mix, socialize, and collaborate throughout the day. We report on how the students use the new technology within their own established communal space. Findings show ...

Abstract

Images containing faces are essential to intelligent vision-based human computer interaction, and research efforts in face processing include face recognition, face tracking, pose estimation, and expression recognition. However, many reported methods assume that the faces in an image or an image sequence have been identified and localized. To build fully automated systems that analyze the information contained in face images, robust and efficient face detection algorithms are required. Given a single image, the goal of face detection is to identify all ...

Abstract

We describe a new method for use in the process of co-designing technologies with users called technology probes. Technology probes are simple, flexible, adaptable technologies with three interdisciplinary goals: the social science goal of understanding the needs and desires of users in a real-world setting, the engineering goal of field-testing the technology, and the design goal of inspiring users and researchers to think about new technologies. We present the results of designing and deploying two technology probes, the messageProbe and the ...

Abstract

While most supervisory control system interfaces use multiple screens, they lack support for understanding, navigating and manipulating the underlying information space. The authors propose the Intelligent Zoom as a network system metaphor which will provide the needed support. The authors use the zoom as an overview screen, to which additional work screens have been added, but this reintroduces many of the problems which the zoom solved. In this paper the authors explore the issues in designing a two-screen interface which exploits ...

Abstract

We present the continuous zoom, a distorted view method for displaying hierarchically-organized, two-dimensional networks. The method is suitable for large networks, such as those found in interfaces to complex supervisory control systems. The continuous zoom shows detail in context, unlike simple pan and zoom techniques, and allows for more than one focus point, unlike fisheye viewing. The algorithm and variations are described ...

Abstract

We present EMMIE (Environment Management for Multiuser Information Environments), a prototype experimental user interface to a collaborative augmented environment. Users share a 3D virtual space and manipulate virtual objects that represent information to be discussed. We refer to EMMIE as a hybrid user interface because it combines a variety of different technologies and techniques, including virtual elements such as 3D widgets, and physical objects such as tracked displays and input devices.... ...

Abstract

StretchTools is a set of tools for manipulating the screen space. The user interface uses the metaphor of stretching a rubber sheet. The basic tool in StretchTools is the handle. A handle is an one-dimensional rigid object of a fixed orientation, either horizontal or vertical. As a handle is placed on the screen, engaged, and pulled, the screen expands on one side of the handle and contracts on the other side. Graphical objects on the screen transforms accordingly. The other type of basic tool... ...

Abstract

This paper describes a novel method for the visualization of hierarchically structured information. The Tree-Map visualization technique makes 100% use of the available display space, mapping the full hierarchy onto a rectangular region in a space-filling manner. This efficient use of space allows very large hierarchies to be displayed in their entirety and facilitates the presentation of semantic information. ...

Abstract

In many contexts, humans often represent their own “neighborhood” in great detail, yet only major landmarks further away. This suggests that such views (“fisheye views”) might be useful for the computer display of large information structures like programs, data bases, online text, etc. This paper explores fisheye views presenting, in turn, naturalistic studies, a general formalism, a specific instantiation, a resulting computer program, example displays and an evaluation. ...

Abstract

A fisheye lens is a very wide angle lens that shows places nearby in detail while also showing remote regions in successively less detail. This paper describes a system for viewing and browsing planar graphs using a software analog of a fisheye lens. We first show how to implement such a view using solely geometric transformations. We then describe a more general transformation that allows hierarchical, structured information about the graph to modify the views. Our general transformation is ...
