    Non-Intrusive Audible Quick Response Code for media application
    (Stellenbosch : Stellenbosch University, 2015-02) McGrath, Neethling; Roux, G. W.
    ENGLISH ABSTRACT: This study details the design of an audible QR Code. The audible QRCode seeks to increase the rate of information exchanged in a human interaction and increase the quality of communication by altering the delivery medium of a QRCode. The delivery medium is changed from a two dimensional bar code to a audio signal. The design is discussed in detail grounded on telecommunication theory including signal modulation, packet construction and error correction. Three techniques were tested in order to reduce the possible intrusive characteristics of the audible QR Code on media content. The commercial uses of the audible QR Code is discussed as well as possible competitions and the advantages it has over the traditional visual QR Code.

    VMS display for ITS
    (Stellenbosch : Stellenbosch University, 2013-11) McGrath, Neethling; Booysen, M. J.
    Design and build a prototype of a variable message system to display traffic notifications on the overhead message signs on a highway. The system must make use of the SMART platform to distribute the messages to potentially multiple VMS displays. A means to confirm delivery and successful display of the message is required.
