  • A Model of Two-Thumb Chording on a Phone Keypad
    2015
    Co-Authors: Nirmal Patel, James Clawson, Thad Starner
    Abstract:

    When designing a text entry system for Mobile Phone Keypads, a designer needs to overcome the ambiguity that arises frommapping the 26 letters of the roman alphabet to only 12 keys (0–9, *, #). In this paper, we present a novel two-thumb chording system for text entry on a standard 12-key Mobile Phone Keypad and introduce a performance model based on Fitts ’ Law for an expert user. The model provides a behavioral description of the user and predicts a text entry rate of 55.02 wpm

  • Mobile HCI - A model of two-thumb chording on a Phone Keypad
    Proceedings of the 11th International Conference on Human-Computer Interaction with Mobile Devices and Services - MobileHCI '09, 2009

  • New Technique for Encoding the Secret Message to Enhance the Performance of MSLDIP Image Steganography Method (MPK Encoding)
    2013
    Co-Authors: Abdelmgeid A. Ali, Al Hussien, Seddik Saad
    Abstract:

    Steganography is a Greek origin word which means “hidden writing”. Steganography word is classified into two parts: Steganos which means “secret or covered ” (where you want to hide the secret messages) and the graphic which means “writing”. It is one of the most important techniques of data hiding. By using steganography, secret messages can be hidden in carriers such as images, audio files, text files and videos. In this paper we tried to enhance the performance of the image steganography technique by modifying the secret message itself not the technique of embedding. That’s by using a new encoding technique that we called it Mobile Phone Keypad encoding or MPK encoding, that can represent the secret message characters by two decimal digits only not three decimal digits as ASCII encoding. So, it can save one third of the required space for embedding. Finally, we are hoping to globalize this new MPK encoding technique to be used in the field of steganography
