Passing on & putting to rest: understanding bereavement in the context of interactive technologies

Abstract: While it can be a delicate and emotionally-laden topic, new technological trends compel us to confront a range of problems and issues about death and bereavement. This area presents complex challenges and the associated literature is extensive. In this paper we offer a way of slicing through several perspectives in the social sciences to see clearly a set of salient issues related to bereavement. Following this, we present a theoretical lens to provide a way of conceptualizing how the HCI community could begin to approach such issues. We then report field evidence from 11 in-depth interviews conducted with bereaved participants and apply the proposed lens to unpack key emergent problems and tensions. We conclude with a discussion on how the HCI design space might be sensitized to better support the social processes that unfold when bereavement occurs.

Texture: Human Expression in the Age of Communications Overload

Abstract: Our workdays are so filled with emails, instant messaging, and RSS feeds that we complain that theres not enough time to get our actual work done. At home, we are besieged by telephone calls on landlines and cell phones, the beeps that signal text messages, and work emails on our BlackBerrys. Its too much, we cry (or type) as we update our Facebook pages, compose a blog post, or check to see what Shaquille ONeal has to say on Twitter. In Texture, Richard Harper asks why we seek out new ways of communicating even as we complain about communication overload. Harper explores the interplay between technological innovation and socially creative ways of exploiting technology, between our delight in using new forms of communication and our vexation at the burdens this places on us, and connects these to what it means to be humanalive, connected, expressivetoday. He describes the mistaken assumptions of developers that more is always betterthat videophones, for example, are better than handheldsand argues that users prefer simpler technologies that allow them to create social bonds. Communication is not just the exchange of information. There is a texture to our communicative practices, manifest in the different means we choose to communicate (quick or slow, permanent or ephemeral). The goal, Harper says, should not be to make communication more efficient, but to supplement and enrich the expressive vocabulary of human experience.

The Inside Text: Social, Cultural and Design Perspectives on SMS

Abstract: SMS or Text is one of the most popular forms of messaging. Yet, despite its immense popularity, SMS has remained unexamined by science. Not only that, but the commercial organisations, who have been forced to offer SMS by a demanding public, have had very little idea why it has been successful. Indeed, they have, until very recently, planned to replace SMS with other messaging services such as MMS. This book is the first to bring together scientific studies into the values that texting provides, examining both cultural variation in countries as different as the Philippines and Germany, as well as the differences between SMS and other communications channels like Instant Messaging and the traditional letter. It presents usability and design research which explores how SMS will evolve and what is likely to be the pattern of person-to-person messaging in the future. In short, The Inside Text is a fundamental resource for anyone interested in mobile communications at the start of the 21st Century.

Who's hogging the bandwidth: the consequences of revealing the invisible in the home

Abstract: As more technologies enter the home, householders are burdened with the task of digital housekeeping-managing and sharing digital resources like bandwidth. In response to this, we created and evaluated a domestic tool for bandwidth management called Home Watcher. Our field trial showed that when resource contention amongst different household members is made visible, people's understanding of bandwidth changes and household politics are revealed. In this paper, we describe the consequences of showing real time resource usage in a home, and how this varies depending on the social make up of the household.

Designing a technological playground: a field study of the emergence of play in household messaging

Abstract: We present findings from a field study of Wayve, a situated messaging device for the home that incorporates handwriting and photography. Wayve was used by 24 households (some of whom were existing social networks of family and friends) over a three-month period. We consider the various types of playfulness that emerged during the study, both through the sending of Wayve messages and through the local display of photos and notes. The findings are explored in the context of the literature on play, with the aim of identifying aspects of Wayve's design, as well as the context in which it was used, that engendered playfulness. We also highlight the role of play in social relationships, before concluding with design implications.

Accessing and interacting with information

Abstract: In some implementations, an access device may sense movement in six degrees of freedom for interacting with information in a user interface. In some implementations, a security feature may be included for verifying an authorization of a user to use the access device. Additionally, in some implementations, the access device may establish communication with an available computing device for accessing and interacting with information that may include remotely stored information, cloud data, cloud services, and the like.

Data Store Including a File Location Attribute

Abstract: A data store including a file location attribute is described. In an embodiment, the location attribute for a data element, such as a file or database record, is stored with the bytes of data and records the geographic location of the data element. Writing to this attribute is limited to a single trusted entity, such as an operating system, to ensure that the location data can be trusted and when a data element is moved or replicated, the attribute is updated to reflect the new location of the data element. This location data is made available to users and applications by a metadata service which tracks the locations of data elements and responds to requests from users. Access control policies can been defined in terms of location and stored at the metadata service and the metadata service can then enforce these policies when responding to requests.

Resource Allocation Framework for Wireless/Wired Networks

Abstract: A resource allocation framework for wireless/wired networks is described. In an embodiment, methods of end host based traffic management are described which operate separately from the underlying access control protocol within the network (e.g. wireless MAC protocol or TCP). The rate limits for each flow are set based on per-flow weights, which may be user specified, and based on an estimate of the utilization of the shared resource and the rate limits are adjusted periodically so that the resource is not underutilized or saturated. Some embodiments compute a virtual capacity of the resource which is adjusted to optimize the value of the utilization and then the virtual capacity is shared between flows according to the per-flow weights. Methods for estimating the utilization of a wireless network and the capacity of a broadband access link are also described.

Evaluation of a CE approved ambulatory patient monitoring device in a general medical ward

Abstract: An evaluation of a newly CE approved bedside monitoring device used in a general hospital ward is presented. This evaluation has shown that it is feasible to use the system within this environment to provide medical staff with supplementary information on patient health, at more frequent intervals than traditional monitoring methods. The physiological data recorded by the body worn device is wirelessly transmitted to a patient management system for storage and display. Good correlation between heart rate values recorded by hospital staff and those recorded by the automated Vitalsens VS100 system was observed. The system has highlighted clinical information that routine observations alone did not readily identify. This can provide clinicians with a better view of the overall health status of the patient. Such medical issues include those witnessed in this study, namely paroxysmal AF, ectopic beats, increasing heart rates recorded prior to a hypoglycaemic event, general high and low heart rate trends and various instances where clinically relevant ECG data has been captured.

Cloud mouse: a new way to interact with the cloud

Abstract: In this paper we present a novel input device and associated UI metaphors for Cloud computing. Cloud computing will give users access to huge amount of data in new forms as well as anywhere and anytime, with applications ranging from Web data mining to social networks. The motivation of this work is to provide users access to cloud computing by a new personal device and to make nearby displays a personal displayer. The key points of this device are direct-point operation, grasping UI and tangible feedback. A UI metaphor for cloud computing is also introduced.

Information retrieval using time

Abstract: Information retrieval using time is described. In an embodiment a web-crawler creates time objects which are composites of content of different media types obtained from potentially different sources and, for example, are about the same date or date range. For example, a time object may comprise an image and a piece of text about an event in 1977. In this case the time object may have the date 1977 stored with it as well as URLs of originating web pages. In an embodiment a user is able to query a search engine to retrieve time objects which are displayed in a manner related to the dates of the time objects. For example, the time objects may be displayed in chronological order against a time line. In examples time objects may be dynamically created as a web page is requested and displayed with that web page.

The Metaphysics of Communications Overload

Abstract: This paper enquires into the nature of the act of communication between two or more persons. It proposes that such acts are best conceived of as moral, as related to the performative consequences of the acts in question. Given this, the paper then asks what applicability phrases like ‘overload’ might have, and whether quantitative techniques have a role other than as a heuristic in understanding and designing tools for the control of communication overload between people.
