  • print vs electronic readings in college courses cost efficiency and perceived learning
    Internet and Higher Education, 2014
    Co-Authors: Sung Wook Ji, Sherri Michaels, David Waterman

    Abstract:

    Abstract We report surveys of 101 students in two undergraduate college courses about their use of required readings accessed via a university-administered electronic reserve system. About two-thirds of respondents printed at least some readings, although nearly half of the total pages were read online. Most students who printed incurred substantially lower total costs (in terms of both direct printing expense and time opportunity costs) than the projected price of a printed and bound coursepack with all of the readings—thus suggesting electronic provision to be cost-efficient for most students. Respondents reported an overall preference for electronically supplied readings. The advantage of electronic reserves was overwhelmingly perceived to be cost, but large majorities said they usually read more, and learned more, when printed readings are supplied. These findings suggest that university and student incentives to employ electronically supplied readings may be misaligned.

  • E-Textiles for Autonomous Location Awareness
    IEEE Transactions on Mobile Computing, 2007
    Co-Authors: Madhup Chandra, Mark T. Jones, Thomas L. Martin

    Abstract:

    This paper describes an autonomous, wearable location awareness system that determines a user’s location within a building given a map of that building. The system uses a moderate number of ultrasonic range transceivers as the sensing elements. Given a set of range readings from these sensors, the system attempts to match those actual readings to expected readings associated with a set of candidate locations for the wearer. These expected readings are calculated using a simulation model of the propagation of ultrasonic signals within a building. A complementary algorithm is given for determining the wearer’s movement between rooms, allowing for the uncertainty associated with sensor readings in complex, multiroom environments. A wearable prototype system is described and results from this system in a range of scenarios are presented and analyzed

  • E-textiles for autonomous location awareness
    Eighth International Symposium on Wearable Computers, 2004
    Co-Authors: Madhup Chandra, Mark T. Jones, T.l.m. Bradley

    Abstract:

    In this paper, we describe an autonomous, wearable electronic textile location awareness system that will determine a user’s location within a building given a map of that building. The system uses a moderate number of ultrasonic range transceivers as the sensing elements. Given a set of range readings from these sensors, the system attempts to match those actual readings to expected readings associated with a set of candidate locations for the wearer. These expected readings are calculated using a simulation model of the propagation of ultrasonic signals within a building. An additional algorithm is given for determining the wearer’s movement between rooms, allowing for the uncertainty associated with sensor readings in complex, multiroom environments. A wearable prototype system is described and results from this system in a variety of situations are presented.
