  text: In this paper we present a system for indoor navigation based on received
    signal strength index information of Wireless-LAN access points and relative position
    estimates. The relative position information is gathered from inertial smartphone
    sensors using a step detection and an orientation estimate. Our map data is hosted
    on a server employing a map renderer and a SQL database. The database includes
    a complete multilevel office building, within which the user can navigate. During
    navigation, the client retrieves the position estimate from the server, together
    with the corresponding map tiles to visualize the user's position on the smartphone
    display.

  text: In this paper we present a system for car navigation by fusing sensor data
    on an Android smartphone. The key idea is to use both the internal sensors of
    the smartphone (e.g., gyroscope) and sensor data from the car (e.g., speed information)
    to support navigation via GPS. To this end we employ a CAN-Bus-to-Bluetooth adapter
    to establish a wireless connection between the smartphone and the CAN-Bus of the
    car. On the smartphone a strapdown algorithm and an error-state Kalman filter
    are used to fuse the different sensor data streams. The experimental results show
    that the system is able to maintain higher positioning accuracy during GPS dropouts,
    thus improving the availability and reliability, compared to GPS-only solutions.

  text: In this paper we present a novel vehicle tracking method which is based on
    multi-stage Kalman filtering of GPS and IMU sensor data. After individual Kalman
    filtering of GPS and IMU measurements the estimates of the orientation of the
    vehicle are combined in an optimal manner to improve the robustness towards drift
    errors. The tracking algorithm incorporates the estimation of time-variant covariance
    parameters by using an iterative block Expectation-Maximization algorithm to account
    for time-variant driving conditions and measurement quality. The proposed system
    is compared to an interacting multiple model approach (IMM) and achieves improved
    localization accuracy at lower computational complexity. Furthermore we show how
    the joint parameter estimation and localizaiton can be conducted with streaming
    input data to be able to track vehicles in a real driving environment.

  text: A combination of GPS (global positioning system) and INS (inertial navigation
    system) is known to provide high precision and highly robust vehicle localization.
    Notably during times when the GPS signal has a poor quality, e.g. due to the lack
    of a sufficiently large number of visible satellites, the INS, which may consist
    of a gyroscope and an odometer, will lead to improved positioning accuracy. In
    this paper we show how velocity information obtained from GSM (global system for
    mobile communications) signalling, rather than from a tachometer, can be used
    together with a gyroscope sensor to support localization in the presence of temporarily
    unavailable GPS data. We propose a sensor fusion system architecture and present
    simulation results that show the effectiveness of this approach.

  text: Smart homes provide their users with maximum comfort and convenience. In this
    paper, we present a profile management framework for situation-dependent customization
    in smart home environments, which meet the user preferences with given device
    capabilities. We apply profile processing and evolution methods to customize profiles
    on the fly and to automatically evolve user preferences. Furthermore, we give
    a comprehensive study on profile management technology.
