The Future of Human-Computer Interaction: Overview of Input Devices
The future of human-computer interaction: overview of input devices Fabrizio Fornari School of Computer Science H´ask´olinn´ıReykjav´ık- Reykjav´ıkUniversity Reykjav´ık,Iceland November, 2012 Abstract We are in 2012 and we are still using the mouse and the keyboard to interact with a computer. We have seen a lot of changes in the world of Computer Science, relating to: performance, design and the way we interact with the computer. Differ- ent input devices have been developed around the computer, starting from the most recent touchscreens, continuing with webcams, microphones, and arriving to the oldest mice and keyboards. The aim of this research is to let the reader imagine a new way to interact with the computer. To reach our purpose, we introduce advanced technologies such as: Speech and Voice Recognition, Electronic Perception, Eye Tracking and Brain Computer In- terfaces. We propose examples of the cited technologies that may change the paradigm that saw, until now, keyboard and mouse as leaders of the input devices. 1 1 Introduction From the computer's birth1, we saw a lot of changes in the world of Com- puter Science. Changes relating to: performance, design and human-computer interaction [49]. A few years ago, the words \input device" evoked in our mind only two specific objects: the keyboard and the mouse - the main instruments used to provide data to a personal computer. Keyboard and mouse are, in fact, two of the first input devices in the history of computer. Nowadays, with the evolution of computers, we have a large set of input de- vices that changed the way we interact with the computer. -

DESCRIPTORS *Communication (Thought Transfer); Educational Innovation; *Educational Radio; Educational' Technology; Elementary Secondary Education; Interdisciplinary Approach; Language Arts; Self Esteem; *Student Motivation; ''Teaching Methods; *Vocational Education IDENTIFIERS *Ham Radio ABSTRACT Amateur radio is a technology and activity that offers great potential when integrated into academic or vocational curricula. Programs with electrical, electronics, and electromechanical content can benefit from the use of amateur radio, and can also enhance language and communications skills. The biggest value of amateur radio may lie in its ability to enhance a student's motivation and self-esteem. In addition to its specific vocational and technical applications, amateur radio can assist in teaching basic skills and in reducing the isolation of students and teachers as it promotes interdisciplinary education and cultural awareness. Amateur radio is distinctly different from citizens band, as it is a noncommercial service. Ham operators do not need an electronics background, although technical knowledge and skills are helpful. Several examples of the educational use of amateur radio illustrate its potential for academic and vocational education. -

Executive Summary of the ICAO Position for ITU WRC-15 Radio
Executive Summary of the ICAO Position for ITU WRC-15 Radio frequency spectrum is a scarce natural resource with finite capacity for which demand is constantly increasing. The requirements of civil aviation as well as other spectrum users continue to grow at a fast pace, thus creating an ever-increasing pressure to an already stretched resource. International competition between radio services obliges all spectrum users, aeronautical and non- aeronautical alike, to continually defend and justify retention of existing or addition of new frequency bands. The ICAO Position aims at protecting aeronautical frequency spectrum for all radiocommunication and radionavigation systems used for ground facilities and on board aircraft. The ICAO Position addresses all radioregulatory aspects on aeronautical matters on the agenda for the WRC-15. The items of main concern to aviation include the following: identification of additional frequency bands for the International Mobile Telecommunications (IMT). Under this agenda item, the telecommunications industry is seeking up to 1200 MHz of additional spectrum in the 300 MHz to 6 GHz range for mobile and broadband applications. It is expected that a number of aeronautical frequency bands will come under pressure for potential repurposing, especially some of the Primary Surveillance Radar (PSR) bands. Existing frequency allocations which are vital for the operation of aeronautical very small aperture terminal (VSAT) ground-ground communication networks, especially in tropical regions, are also expected to come under pressure. Due to decisions made by a previous WRC, this has already become a problematic issue in Africa. WRC-15 agenda items 1.1 and 9.1.5 refer; potential radioregulatory means to facilitate the use of non-safety satellite service frequency bands for a very safety-critical application, the command and control link for remotely piloted aircraft systems (RPAS) in non-segregated airspace. -
A Simultaneous Radiotelephone and Visual Range Beacon for the Airways
RP341 A SIMULTANEOUS RADIOTELEPHONE AND VISUAL RANGE BEACON FOR THE AIRWAYS By F. G. Kear and G. H. Wintermute ABSTRACT Increased use of the airway radio services by transport operators has resulted in a demand for continuous range-beacon service. At the same time the weather broadcast information has increased in importance and the interruptions to the beacon service have become more frequent. To eliminate difficulties arising from this conflict a transmitting system has been developed which provides simul- taneous transmission of visual range-beacon and radiotelephone signals. This system is designed to employ existing equipment so far as possible. By combining two transmitting sets into one the cost of buildings and antenna equipment is reduced. Continuous check on the operation of both systems can be obtained with less personnel than required at present. The transmitting set consists of a 2-kw. radiotelephone transmitter operating into a nondirective antenna system and an additional set of amplifier branches supplying power through a goniometer into two loop antennas. The two antenna systems are symmetrically disposed with respect to each other, and coupling effects are balanced out to prevent distortion of the space pattern. The phase of the currents in the different antenna systems is controlled by a phase shift unit and means for checking the adjustment of this phase relationship continuously is provided. The equipment on the airplane to receive this service is changed only by the addition of a small filter unit which keeps the low-frequency reed voltages from reaching the head telephones and the voice frequencies from the reed indicator. -

Global Maritime Distress and Safety System (GMDSS) Handbook 2018 I CONTENTS
FOREWORD This handbook has been produced by the Australian Maritime Safety Authority (AMSA), and is intended for use on ships that are: • compulsorily equipped with GMDSS radiocommunication installations in accordance with the requirements of the International Convention for the Safety of Life at Sea Convention 1974 (SOLAS) and Commonwealth or State government marine legislation • voluntarily equipped with GMDSS radiocommunication installations. It is the recommended textbook for candidates wishing to qualify for the Australian GMDSS General Operator’s Certificate of Proficiency. This handbook replaces the tenth edition of the GMDSS Handbook published in September 2013, and has been amended to reflect: • changes to regulations adopted by the International Telecommunication Union (ITU) World Radiocommunications Conference (2015) • changes to Inmarsat services • an updated AMSA distress beacon registration form • changes to various ITU Recommendations • changes to the publications published by the ITU • developments in Man Overboard (MOB) devices • clarification of GMDSS radio log procedures • general editorial updating and improvements. Procedures outlined in the handbook are based on the ITU Radio Regulations, on radio procedures used by Australian Maritime Communications Stations and Satellite Earth Stations in the Inmarsat network. Careful observance of the procedures covered by this handbook is essential for the efficient exchange of communications in the marine radiocommunication service, particularly where safety of life at sea is concerned. Special attention should be given to those sections dealing with distress, urgency, and safety. Operators of radiocommunications equipment on vessels not equipped with GMDSS installations should refer to the Marine Radio Operators Handbook published by the Australian Maritime College, Launceston, Tasmania, Australia. No provision of this handbook or the ITU Radio Regulations prevents the use, by a ship in distress, of any means at its disposal to attract attention, make known its position and obtain help. -

Article a Look at S&T Awareness
SISSA – International School for Advanced Studies Journal of Science Communication ISSN 1824 – 2049 http://jcom.sissa.it/ Article A look at S&T Awareness - Enhancements in India Chandra Mohan Nautiyal Basing mainly on author's direct involvement in some science communication efforts in India, and other reports, this contribution depicts and analyses the present science communication/ popularization scenario in India. It tries to dispel a myth that rural people don't require or don’t crave for S&T information. It discusses need for science and technology communication, sustaining curiosity and creating role models. Citing cases of some natural, 'unnatural' and organized events, it recounts how S&T popularization efforts have fared during the past decade and a half. It's made possible using print, AV and interactive media which, at times, require lot of financial inputs. However, this contribution shows that a number of natural and other phenomena can be used to convince people about power of S&T and in molding their attitude. The cases cited may be from India, but, with a little variation, are true for most of the developing and under- developed societies. 1. Introduction Considering that nearly half of the Indian population is engaged in agriculture but contributes only about one fifth to the GDP, indicates a malaise and calls for more scientific and methodical approach in the farming sector. A change is needed not only in the information base but also the attitude. Therefore, there is a need to examine the role of Science and Technology (S&T) in their lives and ways to improve the level.
