    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2167 KB)  

    This paper presents the development of Spectacles-a modular autonomous, wireless displays platform for integration with eyeglass frames. The Spectacles hardware-software platform includes local computation and communication facilities, an integrated power supply, and modular system building blocks, such as sensors, voice-to-text and text-to-speech components, localization and positioning units, and microcameras and micodisplays units. Developers can easily assemble the system building blocks to application-specific instances of wearable displays. View full abstract»

  • How to Mitigate Signal Dragging during Wardriving

    Page(s): 20 - 27
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (4108 KB)  

    In wardriving, test devices in moving vehicles measure received signal strengths (RSSs) from nearby base stations (BSs) and record them with location information, which is a key component in localization technologies. In this article, the authors analyze the wardriving data in real WCDMA, GSM, and Wi-Fi networks and describe how signal dragging degrades their performance. They also propose three methods for postprocessing wardriving data to filter out any outdated BS information, thereby mitigating this effect. View full abstract»

  • LOC8: A Location Model and Extensible Framework for Programming with Location

    Page(s): 28 - 37
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (16256 KB)  

    Location is a core concept in most pervasive systems-and one that's surprisingly hard to deal with flexibly. Using a location model supporting a range of expressive representations for spaces, spatial relationships, and positioning systems, the authors constructed LOC8, a programming framework for exploring location data's multifaceted representations and uses. With LOC8, developers can construct complex queries by combining basic queries and additional contextual information. View full abstract»

  • Human Activity Recognition and Pattern Discovery

    In principle, activity recognition can be exploited to great societal benefits, especially in real-life, human centric applications such as elder care and healthcare. This article focused on recognizing simple human activities. Recognizing complex activities remains a challenging and active area of research and the nature of human activities poses different challenges. Human activity understanding encompasses activity recognition and activity pattern discovery. The first focuses on accurate detection of human activities based on a predefined activity model. An activity pattern discovery researcher builds a pervasive system first and then analyzes the sensor data to discover activity patterns. View full abstract»

  • Service Composition Issues in Pervasive Computing

    Page(s): 62 - 70
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1488 KB)  

    Combining existing services to create new pervasive computing services involves special design considerations, including context awareness, contingency management, device heterogeneity, and user empowerment. Service composition is a natural concept around which to structure pervasive systems and individuate parts of them that are suitable for contingency management, application, storage, and so on. The notion of service composition also provides a natural frame for addressing systemic issues such as performance, usability, and security. In this case, such characteristics aren't determined by a particular service but rather by the software architecture-how services are combined. View full abstract»

  • A Low-Power, Battery-Free Tag for Body Sensor Networks

    Page(s): 71 - 77
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1628 KB)  

    A new tag for pervasive sensing applications consists of a custom integrated circuit, an antenna for radio frequency energy harvesting, and sensors for monitoring physiological parameters. This paper presents a wearable tag design that can monitor multiple signals. The tag generates an alarm when it suspects a patient emergency. To quickly cover a large portion of the population at risk, we kept the tag affordable (less than US$2 each when manufactured in volume), disposable, small, and easy to use. Such tags would be useful for hospitals, facilities for infants and the elderly, and ordinary homes to detect and alert caregivers to possible problems including SCA and SIDS. View full abstract»

  • Eigenplaces: Segmenting Space through Digital Signatures

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1425 KB)  

    Researchers use eigendecomposition to leverage MIT's Wi-Fi network activity data and analyze to the physical environment. We proposed a method to analyze and categorize wireless access points based on common usage characteristics that reflect real-world, placed-based behaviors. It uses eigendecomposition to study the Wi-Fi network at the Massahusetts Institute of Technology (MIT), correlating data generated as a byproduct of network activity with the physical environment. Our approach provides an instant survey of building use across the entire campus at a surprisingly fine-grained level. The resulting eigenplaces have implications for reseach across a range of wireless technology as well as potential applications in network planning, traffic and tourism management, and even marketing.

    Cars offer an interesting but challenging microcosm for pervasive computing research and, in particular, for interaction with pervasive computing systems. Increasingly, researchers are looking at interactive applications in the car and investigating human-car interaction from a computer science—rather than an ergonomics or mechanical engineering—perspective. This article reports on the International Conference on Automotive User Interfaces and Interactive Vehicular Applications, wherein participants shared presentations on topics such as aesthetics, user interaction and distraction, safety, and driver monitoring.
