  • PREFACE TO THE SECOND EDITIONIt gives the author and the editor immensepleasure in presenting the Second edition withall marked improvements over the previousone. Basically the main idea of publishing thismagazine is to create a sense of research andscience in the young technocrats. This is alsokept in mind that the way of lucidness is muchclear in approach. It covers articles-Biomedical, Solar, Embedded and many moreassociated fields. The author would also like tothank the readers(both teachers and students)who sent their valuable suggestions thatbecame the basis for the revision of thismagazine.

    The author would also like to appreciate thesincere efforts and contribution made by hisstudent Praveen G Nair in presentation of thisnew form.

    Lastly, but not the least, the author is thankfulto Rahul Sharma for bringing this magazine intime.

    Cell.The Research and Development cell

    (SSIPMT) works to implement the

    innovative ideas from the idea pool,

    which are contributed by R & D cell

    members. This cell performs a research

    into challenges present around us in our

    lives to come up with promising

    solutions and to implement them.

    This is the second edition and so We

    expect this magazine would help you in

    view of your technical mission. Any

    mistake in the entire content is deeply

    regreted.We welcome your opinions and

    suggestions regarding the betterment of

    this magazine. You can mail us regarding

  • EOG is a recording technique that allows the standing potential

    between the cornea and the posterior pole of the eye to be recorded.

    The whole process of measurement of EOG is known as

    Electrooculography. This gives a review on Electrooculography and

    its use in various HCI systems. Detection of eye blinks from EOG

    signal has also been included in this review work Using electro-

    oculography (EOG), two types of eye-gaze interfaces have been

    developed; "EOG Pointer" and "EOG Switch". The former enables a

    user to move a computer cursor or to control a machine using only

    eye-gaze, regardless of drifting signal and blinking artifacts. In

    contrast, the latter output an ON/OFF signal only. Although it has the

    least simple function, it enables every user easily to turn ON/OFF a

    nurse-call device or to send one bit signal to a personal computer

    with high stability and reliability.

    The EOG Pointer consists of three modules; an EOG recording unit,

    a signal processor and a display unit . Disposable solid-gel electrodes

    connected to pinch-clip leads were attached to the right and left

    temples of a subject and to the forehead as a reference . Set a

    biopotential amplifier as DC mode, the EOG was amplified, and

    sampled to a computer through 12-bits analog I/O board with 200 Hz

    sampling frequency. Using EOG data that was collected by the EOG

    recording unit, the signal processor computes the direction of the

    user's eye gaze after the certain calibration mentioned shortly. A

    pointer on a computer monitor was then displayed to show the user's

    eye-gazing point in real time. At this moment, the individual's head

    was fixed into a chin-rest stabilizing apparatus because head

    movement leads to recording artifact. However, we have

    incorporated a head motion capturing system into the EOG Pointer,

    and it has become successful to allow for greater freedom of

    movement for the subject . 7

  • The above trials demonstrated how the EOG Pointer was useful as aneye-gaze interface if drifting signal and blinking artifacts wereproperly handled. The clinical trials of the EOG Pointer, however,reached the different conclusion. Subjects in the clinical trial, whosuffered from ASL or muscular dystrophy, were not so interested incursor control. Although the EOG Pointer has higher reliability, manyof subjects needed something more reliable and simple. Probably thisis the case of Less is More slogan . According to this slogan, everysingle element in a user interface places some additional burden onthe user in terms of having to consider whether to use that element.Having fewer options will often mean better usability because theusers can concentrate on understanding those fewer options. TheEOG Pointer is relatively simple and reliable comparing to other eye-gaze interfaces, it is still redundant for patients in a real world.Therefore, my research group switched our design concept to developthe simple version of the EOG Pointer, called EOG Switch.

  • 7 hidden features

    1).Your Omni box is a Calculator

    Omni box in Google Chrome

    As you may or may not know, Google will calculate basic math in thesearch bar. However, did you know that you can access a similar mathfunction in your omnibox without ever going to Just type ina basic math problem and the correct answer will appear in thesuggestions below the omnibox without pressing enter (as you have todo on

    2).Your Omni box Is a Unit Converter


  • Your omnibox can also perform Google-like unit conversions without going toGoogle. As with the calculator, the correct answer will appear in the suggestionsbelow without ever hitting enter. As you type, Chrome will automaticallyconvert your number into a unit that you may or may not want. So, if you type"9 inches," Chrome may automatically suggest conversion rate to centimeters.

    3) A Simple Image Browser

    Have you ever been organizing your computer and come across some jpeg andyou have no idea what it is or how it got on your computer? Well if you justwant to see what it is real quick, you can just drag it directly into your Chromebrowser window and take a quick gander.

    4) Drag to search

    Why CROME?

    In design terminology, chrome refers to the non-webpage parts of the browser's interface

    the toolbars, tabs and buttons. This is part of the reason Chrome was chosen as the

    browser name.


  • Highlighting a word and performing a drag and drop is fundamentally the same asperforming a cut and paste, so it stands to reason that you could just highlight aword or phrase and drag it into the omnibox to perform a Web search.

    5) Navigate Up and Down Using Key Commands

    You can use the spacebar to scroll down on any webpage, and you can scroll back up by pressing Shift and the spacebar.

    6) Open Accidentally Closed Tabs

    Have you ever mistakenly closed a tab? We all have. BUT thankfully Chrome is aforgiving browser and makes it possible to get it all back. All you have to do is pressControl-Shift-T (Command-Shift-T on a Mac) and Chrome will reopen any recentlyclosed tabs.

    7)A Lot of Information Hidden in That Omnibox

    You may have also noticed on the far left of your omnibar a little icon thatresembles a folded piece of paper or lock (to signify a secured site). If you click onit, it will prompt a window with all sorts of information about the site as well aspermissions particular to that site, which you can then manipulate.
