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. -

Thomas Edison Alexander Graham Bell
The Inventing Game Cut out the images. Cut out the name of the inventor separately. Read out the text as a clue. Can people match the correct name and image? THOMAS EDISON Clue The first great invention developed by (don’t say the name) Thomas Edison was the tin foil phonograph. A prolific producer, Edison is also known for his work with light bulbs, electricity, film and audio devices, and much more. ALEXANDER GRAHAM BELL Clue In 1876, at the age of 29, (don’t say the name) Alexander Graham Bell invented his telephone. Among one of his first innovations after the telephone was the "photophone," a device that enabled sound to be transmitted on a beam of light. GEORGE WASHINGTON CARVER Clue (Don’t say the name) George Washington Carver was an agricultural chemist who invented 300 uses for peanuts and hundreds of more uses for soybeans, pecans, and sweet potatoes. His contributions chang ed the history of agriculture in the south. ELI WHITNEY Clue (Don’t say the name) Eli Whitney invented the cotton gin in 1794. The cotton gin is a machine that separates seeds, hulls, and other unwanted materials from cotton after it has been picked. JOHANNES GUTTENBERG Clue (don’t say the name) Johannes Gutenberg was a German goldsmith and inventor best known for the Gutenberg press, an innovative printing machine that used movable type. JOHN LOGIE BAIRD Clue (don’t say the name) John Logie Baird is remembered as the inventor of mechanical television (an earlier version of television). Baird also patented inventions related to radar and fibre optics. -

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. -
