UBICOMP

Through an iterative design approach, we have proposed and evaluated ways of incorporating user-created information into context-aware systems. We implemented and tested a location-sensitive college campus tour guide called Campus Aware that allows ...

This paper describes a system called ComicDiary that automatically creates a personal diary in a comics style. ComicDiary is built as a sub-system of our ongoing project (C-MAP) to develop a personal guidance system for exhibition touring at museums, ...

A maintenance engineer who talks to pumps and pipes may not seem like the ideal person to entrust with keeping a factory running smoothly, but we hope that our Mobile Reality framework will enable such behavior in the future to be anything but ...

We report on our experiences implementing and testing Rememberer, a tool for recording visits to museums. We describe field trials at the Exploratorium, an interactive science museum in San Francisco. This challenging environment enabled us to verify ...

As ubiquitous computing becomes widespread, we are increasingly coming into contact with "shared" computer-enhanced devices, such as cars, televisions, and photocopiers. Our interest is in identifying general issues in personalizing such shared everyday ...

To be successful, ubicomp applications must be designed with their environment and users in mind and evaluated to confirm that they do not disrupt the users' natural workflow. Well-established techniques for understanding users and their environment ...

Occupants of future computing environments with ubiquitous display devices may feel inundated with changing digital information. One solution is to create a reasoning module that accepts requests to display information from multiple applications and ...

In this paper we explore an activity-centered computing paradigm that is aimed at supporting work processes that are radically different from the ones known from office work. Our main inspiration is healthcare work that is characterized by an extreme ...

In this paper we propose a software architecture for observing and modeling human activity. This architecture is derived from an ontology for context awareness. We propose a model in which a user's context is described by a set of roles and relations. ...

Systems for tracking faces using computer vision have recently become practical for human-computer interface applications. We are developing prototype systems for face-responsive interaction, exploring three different interface paradigms: direct ...

In this paper, we present a stereo-based face tracking system which can track the 3D position and orientation of a user in real-time, and the system's application for interaction with a large display. Our tracking system incorporates dynamic update of ...

We have designed an active tagging system that responds to a coded optical beam from several meters away. The tags contain a minimalist microprocessor that ambiently operates in shutdown mode and, upon detecting particular frequency components in the AM-...

In this paper we discuss the development of 'Z-Tiles' in conjunction with a sister project, 'Self-Organising Sensors' (SOS). Combined, these projects will result in a pressure sensitive, self-organising, interactive sensor design that can be embedded ...

In this paper, we propose a framework for supporting sociallycompatible privacy objectives in ubiquitous computing settings. Drawing on social science research, we have developed a key objective called the Principle of Minimum Asymmetry, which seeks to ...

The Personal Server is a mobile device that enables you to readily store and access the data and applications you carry with you through interfaces found in the local environment. Unlike conventional mobile computers with relatively poor user interfaces,...

This paper discusses how ID-based information access, i.e., information access that utilizes IDs of physical entities, can be enhanced to function in a dynamic and social environment, where users can participate in the process of designing and extending ...

We introduce a new concept of networking objects in everyday environments. The basic idea is to build on the familiar use of surfaces such as walls and boards for attachment of mundane objects such as light controls, pictures, and notes. Hence our ...

Large displays have several natural affordances that can simplify small group collaborative work. They are large enough to hold multiple work areas, they are easy to see and can be manipulated directly via touch. When placed into group and public spaces, ...

Protecting personal privacy is going to be a prime concern for the deployment of ubiquitous computing systems in the real world. With daunting Orwellian visions looming, it is easy to conclude that tamper-proof technical protection mechanisms such as ...

Location modeling and representation are crucial technologies for context-aware applications. In this paper, we present a novel location model combining the virtues of both the hierarchical and coordinate location models, and we introduce a computable ...

Indoor ultrasonic location systems provide fine-grained position data to ubiquitous computing applications. However, the ultrasonic location systems previously developed utilize narrowband transducers, and thus perform poorly in the presence of noise ...

Networked Surfaces are a novel technology, using contact with physical surfaces such as desks to provide network connectivity for mobile devices. In addition, Networked Surfaces can accurately estimate the positions and orientations of connected devices,...

Measuring the locations of people in a building is an important part of ubiquitous computing. We present new hardware and software for this purpose. The hardware, called SmartMoveX, is an active badge system in which a small radio transmitter is ...

This note describes a standalone generic location event simulator that has been designed for the visualisation, scalability testing and evaluation of location-aware event-driven middleware and applications.

Ubiquitous computing is finally becoming a reality. However, there are many practical issues that stand in the way of mass acceptance. We have been investigating these practical concerns within the context of an autonomous application that takes care of ...

Load sensing is a mature and robust technology widely applied in process control. In this paper we consider the use of load sensing in everyday environments as an approach to acquisition of contextual information in ubiquitous computing applications. ...

Tennenhouse [1] coined the term proactive computing where humans get out of the interaction loop and may be serviced specifically according to their needs and current situation. In this paper we propose a framework for proactive guidance which aims to ...

This paper describes a distributed, multi-sensor system architecture designed to provide a wearable computer with a wide range of complex context information. Starting from an analysis of useful high level context information we present a top down ...

Nutrition has a big impact on health, including major diseases such as heart disease, osteoporosis, and cancer. This paper presents an application designed to help people keep track of the nutrional content of foods they have eaten. Our work uses ...
