Itwill be of particular importance in the new millennium asusers move away from their desktops and into settingswhere their contexts are changing rapidly. Context isdifficult to use because, unlike other forms of user input,there is no common, reusable way to handle it. As a result,context-aware

We discuss the requirements for dealing with context in a smart environment and present a software infrastructure solution we have designed and implemented to help application designers

We are investigating how an environment made aware of the location and activities of its occupants can better support direct human-human communication. Specifically, we have instrumented a home to explore lightweight, spontaneous hands-free communication between residents in different parts of the

Between visits, diabetes-related issues may not be frequently reflected, learned, and documented by the patients, limiting their self-awareness and knowledge about their condition. We designed a text-messaging system to help resolve this problem. In a pilot, randomized controlled trial with 30 adolescents, we examined the effect of text messages about symptom awareness and diabetes knowledge on glucose control and quality of life. The intervention group that received more text messages between visits had significant improvements in quality of life.

We depict three social scenarios that show the feasibility and applicability of SocialMirror.

In this study, we leverage the use of mobile phones by pediatric patients and report results from a four-month randomized controlled trial (RCT). We examined: 1) how a SMS system impacted the health outcomes

The goals of the survey were to determine who loses objects, what objects are lost, and what strategies are used to locate objects. The current findings suggest that young and middle-aged

Automated detection of events of interest is therefore critical so that these points in the data can be marked for later review. However, for some important chronic health conditions, such as pain and depression, automated detection is only partially achievable. To assist with this

However, in reality, both sensed and interpreted context i s often imper- fect. In this paper, we describe an architecture that supports the building of context-aware services that assume c ontext is imperfect and allows for the refinement of this imperfect context

Our system addresses the tradeoff between speed and accuracy of pen- based text entry by substituting precision on the part of the user for ease of recognition on the part of the computer. Cirrin supports ease of recognition by the computer combined with natural,

For the foreseeable future, use of recognition based systems will introduce uncertainty into the input process. If interactive systems are going to work robustly with recognition-based input, it will be

In this paper, we introduce a novel method to visualize and navigate through the collection by creating a mosaic image that represents the compilation. This image is generated by a labeling-based layout algorithm using various sizes of sample tile images from the collection. Each tile
