Connections is a file system search tool that combines traditional content-based search with context information gathered from user activity. By tracing file system calls, Connections can identify temporal relationships between files and use them to expand and reorder traditional content search results. Doing so improves both recall (reducing falsepositives) and precision (reducing false-negatives). For example, Connections improves the average recall (from 13% to 22%) and precision (from 23 % to 29%) on the first ten results. When averaged across all recall levels, Connections improves precision from 17 % to 28%. Connections provides these benefits with only modest increases in average query time (2 seconds), indexing time (23 seconds daily), and index size (under 1 % of the user’s data set).

This paper presents a context-aware mobile recommender system, codenamed Magitti. Magitti is unique in that it infers user activity from context and patterns of user behavior and, without its user having to issue a query, automatically generates recommendations for content matching. Extensive field studies of leisure time practices in an urban setting (Tokyo) motivated the idea, shaped the details of its design and provided data describing typical behavior patterns. The paper describes the fieldwork, user interface, system components and functionality, and an evaluation of the Magitti prototype. Author Keywords Field studies, user experience design, interaction, contextaware computing, mobile recommendation systems, leisure. ACM Classification Keywords H5.m.

Helping computer users rapidly locate files in their folder hierarchies has become an important research topic in today’s intelligent user interface design. This paper reports on FolderPredictor, a software system that can reduce the cost of locating files in hierarchical folders. FolderPredictor applies a cost-sensitive prediction algorithm to the user’s previous file access information to predict the next folder that will be accessed. Experimental results show that, on average, FolderPredictor reduces the cost of locating a file by 50%. Another advantage of FolderPredictor is that it does not require users to adapt to a new interface, but rather meshes with the existing interface for opening files on the Windows platform.

Personal data is growing at ever increasing rates, fueled by a growing market for personal computing solutions and dramatic growth of available storage space on these platforms. Users, no longer limited in what they can store, are now faced with the problem of organizing their data such that they can find it again later. Unfortunately, as data sets grow the complexity of organizing these sets also grows. This problem has driven a sudden growth in search tools aimed at the personal computing space, designed to assist users in locating data within their disorganized file space.

is a new initiative at the MIT Media Laboratory with the goal of magnifying human abilities by an order of magnitude (‘10x’), or more, along various cognitive and physical dimensions. Based on an understanding of human abilities and limitations, technologies can be shaped to extend human reach. By setting our sights on 10x gains, we deliberatively seek human abilities which can be dramatically improved with appropriate technologybased catalysts. We view the underlying challenges of developing assistive technologies for individuals with impairments and bionic technologies for unimpaired individuals as fundamentally similar in nature. Across this spectrum, our aim is to develop technologies that complement rather than replace human abilities. Consider our ability to visually search. There are many mysteries regarding the mechanisms underlying human vision and memory, but we can nonetheless make some simple observation about how we search. When searching for our keys, why do we often look repeatedly in the same places? We might be far more efficient in search if we could keep ourselves from looping to places we have already looked. Imagine a lightweight device, perhaps woven into a pair of eyeglasses, that keeps track of where people have looked and steers them away from looking there again. This search aid would not need to know where the target object is — it would simply augment the person’s visual search routine with a form of extended memory. With the appropriate interface for steering ongoing search, such a technology may lead to human-machine superperformance — more efficient

Abstract. Human memory at its best can perform astonishing feats { the tiniest snippet of information can trigger whole chains of associations, ending at an item long-believed forgotten. While modern information sys-tems excel at systematic manipulation of structured or semi-structured information or even vast repositories of unstructured textual information, they are still far from these capabilities. Unfortunately, human memory is also prone to failure. Thus, a per-sonal information system that augments human memory through suit-able means to store and access information could have huge benets. In this paper, we introduce a problem domain for research on such a sys-tem: researchers who attend academic conferences and need to remember names, aliations and research interests of fellow conference attendees and many other types of information. Academic interest in wearable, context-aware systems for information display and capture has strongly increased in the last few years. We present an overview of existing sys-tems and point out unresolved issues. We show that resolving these issues will not only make it possible to build improved augmented memory sys-tems but will also contribute to research in a wider context. Finally, we outline our agenda for research in this area.

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302.

Sharing events with others is an important part of many enjoyable experiences. While most existing co-presence systems focus on work tasks, in this paper we describe a lightweight mobile system designed for sharing leisure. This system allows city visitors to share their experiences with others both far and near, through tablet computers which share photographs, voice and locations. A collaborative filtering algorithm uses historical data of previous visits to recommend photos, web pages and places to visitors. In an extensive user trial we explored how these resources were used to collaborate around a physical place.

Helping computer usersrapidlylocate files in theirfolder hierarchiesisapractical research problem involvingboth intelligentsystemsand userinterfacedesign. Thispaperreportson FolderPredictor, a software system that can reduce the cost of locating files in hierarchical folders. FolderPredictor applies a cost-sensitive prediction algorithm to the user’s previous file access information to predict the next folder that will be accessed. Experimental results show that, on average, FolderPredictor reduces the number of clicks spent on locating a file by 50%. Several variations of the cost-sensitive prediction algorithm are discussed. An experimental study shows that the best algorithm among them is a mixture of the most recently used (MRU) folder and the cost-sensitive predictions. Furthermore, FolderPredictor does not require users to adapt to a new interface, but rather meshes with the existing interface for opening files on the Windows platform.

Abstract. In this paper, we unpack three themes for the multidisciplinary codesign of a physical and digital meeting space environment in supporting collaboration: that social practices should dictate design, the importance of supporting fluidity, and the need for technological artifacts to have a social voice. We describe a prototype meeting space named inSpace that explores how design grounded in these themes can create a user-driven, information-rich environment supporting a variety of meeting types. Our current space includes a table with integrated sensing and ambient feedback, a shared wall display that supports multiple concurrent users, and a collection of storage and infrastructure services for communication, and that also can automatically capture traces of how artifacts are used in the space.
