Abstract Computing devices and applications are now used beyond the desktop, in diverse environments, this trend toward ubiquitous computing is accelerating. One challenge that remains emerging research field ability to enhance behavior of any application by informing it context its use. By context, we refer information characterizes a situation related interaction between humans, applications, surrounding environment. Context-aware promise richer easier interaction, but current state still...

The proliferation of computing into the physical world promises more than ubiquitous availability infrastructure; it suggest new paradigms interaction inspired by constant access to information and computational capabilities. For past decade, application-driven research on abiquitous (ubicomp) has pushed three themes: natural interfaces, context-aware applications, automated capture . To chart a course for future in computing, we review accomplishments these efforts point remaining...

Context-enabled applications are just emerging and promise richer interaction by taking environmental context into account. However, they difficult to build due their distributed nature the use of unconventional sensors. The concepts toolkits widget libraries in graphical user interfaces has been tremendously successtil, allowing programmers leverage off existing building blocks interactive systems more easily. We introduce concept widgets that mediate between environment application same...

We have created a system for identifying people based on their footstep force profiles and tested its accuracy against large pool of data. This floor may be used to identify users transparently in everyday living working environments. user models profile features been able achieve recognition rate 93%. also shown that the effect footwear is negligible accuracy.

One potentially useful feature of future computing environments will be the ability to capture live experiences occupants and provide that record users for later access review. Over last three years, a group at Georgia Institute Technology has designed extensively used particular instrumented environment: classroom captures traditional lecture experience. This paper describes history Classroom 2000 project provides results extended evaluations effect automated on teaching learning There are...

Despite advances in clarifying high level design needs, analyzing a system's ability to meet desired quality criteria is still difficult. The authors propose using scenarios make analysis more straightforward. In their case study report, they analyze lessons learned with this approach. They developed the Software Architecture Analysis Method, an approach that uses gain information about attributes. Scenarios are brief narratives of expected or anticipated system from both user and developer...

While software architecture has become an increasingly important research topic in recent years, insufficient attention been paid to methods for evaluation of these architectures. Evaluating architectures is difficult two main reasons. First, there no common language used describe different Second, clear way understanding with respect organization's life cycle concerns -software quality such as maintainability portability, modularity, reusability, and so forth. We address shortcomings by...

In the future, a largely invisible and ubiquitous computing infrastructure will assist people with variety of activities in home at work. The applications that be deployed such systems create manipulate private information provide access to other resources. Securing is challenging for number reasons. Unlike traditional where control has been explored, decisions may depend on context which requests are made. We show how well-developed notion roles can used capture security-relevant...

This paper introduces a low cost, fast and accessible technology to support the rapid prototyping of functional electronic devices. Central this approach 'instant inkjet circuits' is ability print highly conductive traces patterns onto flexible substrates such as plastic films cheaply quickly. In addition providing an alternative breadboarding conventional printed circuits, we demonstrate how technique readily supports large area sensors high frequency applications antennas. Unlike existing...

Recognizing when eating activities take place is one of the key challenges in automated food intake monitoring. Despite progress over years, most proposed approaches have been largely impractical for everyday usage, requiring multiple on-body sensors or specialized devices such as neck collars swallow detection. In this paper, we describe implementation and evaluation an approach inferring moments based on 3-axis accelerometry collected with a popular off-the-shelf smartwatch. Trained data...

Although food journaling is understood to be both important and difficult, little work has empirically documented the specific challenges people experience with journals. We identify key in a qualitative study combining survey of 141 current lapsed journalers analysis 5,526 posts community forums for three mobile Analyzing themes this data, we find discuss barriers reliable entry, negative nudges caused by techniques, social features. Our results motivate research exploring wider range...

Chronic and widespread diseases such as obesity, diabetes, hypercholesterolemia require patients to monitor their food intake, journaling is currently the most common method for doing so. However, subject self-bias recall errors, poorly adhered by patients. In this paper, we propose an alternative introducing EarBit, a wearable system that detects eating moments. We evaluate performance of inertial, optical, acoustic sensing modalities focus on inertial sensing, virtue its recognition...

To address M. Weiser's (ibid., p. 19-25) human-centered vision of ubiquitous computing, the authors focus on physical interaction, general application features and theories design evaluation for this new mode human-computer interaction.
