  • simple numerical analysis of longboard Speedometer data
    Physics Education, 2013
    Co-Authors: Jonathan P Hare
    Abstract:

    Simple numerical data analysis is described, using a standard spreadsheet program, to determine distance, velocity (speed) and acceleration from voltage data generated by a skateboard/longboard Speedometer (Hare 2012 Phys. Educ. 47 409–17). This simple analysis is an introduction to data processing including scaling data as well as simple numerical differentiation and integration. This is an interesting, fun and instructive way to start to explore data manipulation at GCSE and A-level—analysis and skills so essential for the engineer and scientist.

  • skateboard longboard Speedometer project
    Physics Education, 2012
    Co-Authors: Jonathan P Hare
    Abstract:

    A simple, low-cost infrared LED Speedometer is described that can be fitted to a skateboard, longboard or even a bicycle to measure speed. Notes on building, setting up and calibration are given. When used with a low-cost data logger, continuous measurements of speed can be made while out and about. The device forms an interesting science club project and would be a great introduction for potential physicists and engineers to scientific instrument design, testing and calibration as well as generating lots of their own interesting data to analyse.

  • the effects of a simulated head up display Speedometer on perceptual task performance
    Human Factors, 1990
    Co-Authors: Russell J Sojourmer, Jonathan F Antin
    Abstract:

    This study compared the effects of simulated head-up display (HUD) and dashboard-mounted digital Speedometers on key perceptual driving tasks in a simulated driving environment. Subjects were 20 male and female volunteers ranging in age from 19 to 51 years. A videotape, taken from the driver's perspective, of a car traveling along a memorized route served as the test scene. While viewing the test scene subjects performed tasks related to navigation, speed monitoring, and salient cue detection. The simulated HUD Speedometer produced generally superior performance on the experimental tasks; most important, it enabled subjects to respond significantly more quickly to the salient cues. Implications for the effects of HUDs on automobile safety are discussed.

  • dynamic Speedometer dashboard redesign to discourage drivers from speeding
    Human Factors in Computing Systems, 2005
    Co-Authors: Manu Kumar
    Abstract:

    We apply HCI design principles to redesign the dashboard of the automobile to address the problem of speeding. We prototyped and evaluated a new Speedometer designed with the explicit intention of changing drivers' speeding behavior. Our user-tests show that displaying the current speed limit as part of the Speedometer visualization (i.e. the dynamic Speedometer) results in safer driving behavior. Designing with the intent to achieve a particular behavior can be an effective approach for increasing the safety of mission-critical systems. This is an area in which HCI designers can have a significant impact.

  • Real time positioning by fusing differential-GPS and local vehicle sensors
    SICE 2003 Annual Conference (IEEE Cat. No.03TH8734), 2003
    Co-Authors: M. Imamura, K. Kobayashi, K. Watanabe
    Abstract:

    Real-time accurate positioning of a vehicle when driving yields accurate navigation. One of the most popular positioning systems employs differential GPS to determine vehicle position. This paper describes a new method for real-time positioning that fuses differential GPS and the vehicle's local sensors including a Speedometer and optical fiber gyroscope.

  • Absolute speed estimation from sequential frames of omni-directional image
    SICE 2003 Annual Conference (IEEE Cat. No.03TH8734), 2003
    Co-Authors: K. Kobayashi, M. Amemiya, K. Watanabe
    Abstract:

    For autonomous navigation, the omni-directional camera is a suitable sensor for capturing a 360 degree image without any dead angles. In this paper, we propose a new image-based absolute (translational and/or rotational) speed measurement method using sequential frames of an omni-directional image. The proposed method demonstrates the omni-directional camera's ability to function not only as a vision sensor but also as a Speedometer. The validity of the proposed method was examined in real field images.
