  • Using Genetic Algorithms to Design an Optimized Keyboard Layout for Brazilian Portuguese
    Using Genetic Algorithms to Design an Optimized Keyboard Layout for Brazilian Portuguese Gustavo Pacheco1, Eduardo Palmeira1, Keiji Yamanaka1 1Faculdade de Engenharia Eletrica´ – Universidade Federal de Uberlandiaˆ (UFU) Uberlandiaˆ – MG – Brazil fpacheco.gustavo.alves,[email protected], [email protected] Abstract. Currently, keyboards are the most common means of communicating with computers. Despite being the most commonly used keyboard layout, QW- ERTY has had various issues raised concerning its effectiveness, as it is not efficient in English (target language) or in fact other languages. Therefore, this paper presents the development process of a Genetic Algorithm with the inten- tion of generating a more adequate and coherent layout proposal for Brazilian Portuguese, which has its focus on ergonomics and user productivity. Using five ergonomic criteria and a statistical analysis of the characters and sequences of most frequently used pairs in Brazilian Portuguese, a layout approximately 53% better than QWERTY was obtained. 1. Introduction Currently, keyboards are the most common means of communicating with computers. The electronic era has strengthened the unique and dominant position of the QWERTY layout keyboard. This layout had its design conceived in 1874, for typewriters, but it was only in the first decade of the 20th century that it became established as the international keyboard standard. At that time, writers commonly used only their index fingers for typing. The first typists searched for the character and, after finding it, pressed it to make its impression on the paper. It was a slower and more cautious interaction. Only after the 1930s, the typing speed was improved when all ten fingers started to be used as a conventional manner of interaction.

  • Abstract There Has Been a Substantial Growth in Interest in Mobile Text Entry Over Recent Years, Among Both Researchers and Users
    Rhodes University Department of Computer Science Computer Science Honours Literature Review Principal Investigator: Edison Mukadah Supervisor: Greg Foster Co-Supervisor: Hannah Slay Mobile Interface Design and Predictive Text Algorithm For Improved Text Entry Abstract There has been a substantial growth in interest in mobile text entry over recent years, among both researchers and users. Increasingly mobile devices are being used to perform text-intensive applications, such as text messaging, creating a demand for more efficient and easier to use text entry methods. Unlike for desktop computing, no single standard mobile text entry method has emerged. The diversity of mobile devices makes it unlikely that this will occur in the near future. Thus, mobile text entry remains a very open area of research, providing a fertile environment for the development of innovative text entry methods. A necessary part of the development of a new mobile text entry method is a comparison of its performance with existing ones. A review of current best practice for the qualitative and empirical evaluation of mobile text entry methods is presented, alongside a classification of existing mobile text entry methods and the various ways to optimise text entry. A mobile interface that uses a scroll wheel will then be designed together with a predictive text algorithm by combining or improving the various techniques that will be examined by this literature review for improved text entry. Empirical tests will then be conducted to test the hypothesis that the new interface has a faster text entry input rate compared to the traditional Multi-Tap keypad. 1 Introduction 1.1 The Popularity of Mobile Devices Mobile computing devices popularity has escalated astronomically over the past years.

This is a standard where keystrokes from the telephone keypad are translated into dual tone signals over the audio link. It has been gaining popularity for some years now because of its numerous advantages over the traditional telephone signalling scheme. In this project DTMF tone generation and the detection can be done with the help of MATLAB. The Goertzel algorithm implementation examines the energy of one of the two tones from an incoming signal at 8 DTMF frequencies to determine which DTMF frequency is present.

  • 1.Introduction
    1.INTRODUCTION 1 1. INTRODUCTION: Cell phone operated robot is a machine that can be controlled with a mobile. In this project, the robot is controlled by a mobile phone that makes a call to the mobile phone attached to the robot. In the course of a call, if any button is pressed, a tone corresponding to the button pressed is heard at the other end of the call. This tone is called "Dual Tone Multiple- Frequency" (DTMF) tone. The robot perceives this DTMF tone with the help of the phone stacked on the robot. The received tone is processed by the microcontroller with the help of DTMF decoder. The microcontroller then transmits the signal to the motor driver ICs to operate the motors & our robot starts moving Conventionally, Wireless-controlled robots use rf circuits, which have the drawbacks of limited working range, limited frequency range and the limited control. Use of a mobile phone for robotic control can overcome these limitations. It provides the advantage of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls. Although the appearance and the capabilities of robots vary vastly, all robots share the feature of a mechanical, movable structure under some form of control. The Control of robot involves three distinct phases: perception, processing and action. Generally, the preceptors are sensors mounted on the robot , processing is done by the on-board microcontroller or processor, and the task is performed using motors or with some other actuators. In this project the robot, is controlled by a mobile phone that makes call to the mobile phone attached to the robot in the course of the call, if any button is pressed control corresponding to the button pressed is heard at the other end of the call.

K. Gautam2 1Student, M.tech (ECE), S.D. College of Engineering & Technology, Muzaffarnagar 2Principal, S.D. College of Engineering & Technology, Muzaffarnagar ---------------------------------------------------------------------***---------------------------------------------------------------------- Abstract - The communication switching system enables the universal connectivity. The universal connectivity is realized when any entity in one part of the world can communicate with any other entity in another part of the world. In many ways telecommunication will acts as a substitute for the increasingly expensive physical transportation. The telecommunication links and switching were mainly designed for voice communication. With the appropriate attachments/equipments, they can be used to transmit data. A modern society, therefore needs new facilities including very high bandwidth switched data networks, and large communication satellites with small, cheap earth antennas. Speed and size are two important factors while designing the electronic system. It’s Speed of operation and flexibility to modify, measures the performance of the system operation. Traffic handling capacity is an important element of service quality and will therefore play a basic role in this choice Microprocessor/microcontroller (MPMC) system can handle sequential operations with high flexibility and use of Field Programmable Gate Array (FPGA) can handle concurrent operations with high speed in small size area. So combined features of both these systems can enhance the performance of the system. High Performance Hybrid Telephone Network System (HTSS) is designed using combination of stored program control (SPC) and VLSI technology.
