    With the advent of tiny networked devices, Mark Weiser's vision of a world embedded with invisible computers is coming to age. Due to their small size and relative ease of deployment, sensor networks have been utilized by zoologists, seismologists and military personnel. In this paper, we investigate the application of sensor networks to the film industry. In particular, we are interested in augme... View full abstract»

  • Learning to detect user activity and availability from a variety of sensor data

    Publication Year: 2004, Page(s):13 - 22
    Cited by:  Papers (29)  |  Patents (1)

    Using a networked infrastructure of easily available sensors and context-processing components, we are developing applications for the support of workplace interactions. Notions of activity and availability are learned from labeled sensor data based on a Bayesian approach. The higher-level information on the users is then automatically derived from low-level sensor information in order to facilita... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (335 KB) | HTML iconHTML

    There are many navigation systems for visually impaired people but few can provide dynamic interactions and adaptability to changes. None of these systems work seamlessly both indoors and outdoors. Drishti uses a precise position measurement system, a wireless connection, a wearable computer, and a vocal communication interface to guide blind users and help them travel in familiar and unfamiliar e...

    In large scale surveillance applications, coherent presentation of data coming from myriad sensors becomes a problem. For example, tasks such as "locate an intruder" are no longer easy when the user is facing a room of monitors connected to hundreds of cameras. Therefore, there is a need for a system that allows the user to easily navigate the data space. Due to the scale of the application, such ... View full abstract»

    This paper proposes a system for quickly realizing a function for robustly detecting daily human activity events in handling objects in the real world. The system has three functions: 1) robustly measuring 3D positions of the objects; 2) quickly calibrating a system for measuring 3D positions of the objects; 3) quickly registering target activity events; and 4) robustly detecting the registered ev...

    Context-aware computing systems demand an accurate and up-to-date world model which computationally represents the environment they oversee. Systems to date tend to have small-scale implementations with hand-programmed world models. In real environments, manual creation and maintenance of such models is infeasible. This work presents a method of using signals propagating in a multilateration posit... View full abstract»

    Applications in the pervasive computing domain are challenged by the dynamism in which their execution environment changes, e.g. due to user mobility. As a result, applications have to adapt to changes regarding their required resources. In this paper we present PCOM, a component system for pervasive computing. PCOM offers application programmers a high-level programming abstraction which captures... View full abstract»

    There is growing interest in the use of context-awareness as a technique for developing pervasive computing applications that are flexible, adaptable, and capable of acting autonomously on behalf of users. However, context-awareness introduces various software engineering challenges, as well as privacy and usability concerns. In this paper, we present a conceptual framework and software infrastruc...

    People are an important part of many business processes. Current workflow-based implementations of business processes constrain users to the desktop environment; require them to periodically check for pending tasks; and do not support direct or synchronous people-to-people interaction. On the other hand, the wide spectrum of people collaboration tools ranging from telephones to instant messaging a... View full abstract»

    Context awareness will become increasingly important in future domestic consumer electronics. In many domestic context aware applications, there is a need for location and orientation information about persons, devices or objects in the home. This information can be provided by a dedicated indoor location system. A consumer location system should be robust, safe, easy to set up, low cost, and shou... View full abstract»

    One way to improve inferences on sensor data is to tune the algorithms through a time-consuming offline procedure. A less expensive and potentially more accurate method is to use an online procedure based on feedback from users, who often know best what the data means to them. We present a method for user-assisted location inference based on 802.11b wireless signal strengths. A user 'corrects' sys... View full abstract»

    We present the cooperative location-sensing system (CLS), an adaptive location-sensing system that enables devices to estimate their position in a self-organizing manner without the need for an extensive infrastructure or training. Hosts cooperate and share positioning information. CLS uses a grid representation that allows an easy incorporation of external information to improve the accuracy of t... View full abstract»
