talking place value...

Consider this scenario, you are shopping in a supermarket and have a long list of items. You want to do a quick check of the approximate value... This is where your place value comes in real handy.how?
Let the cost of items be like,
rs.1034
rs 973
rs.450
rs.228
rs.1005
rs.824
rs.2000
the best and perhaps the easiest ways to add is by splitting them according to their place values.

thousands - 1000+1000+2000 = 4000
hundreds - 900+400+200+800 = 2300
tens - 70+50+20+20 = 160

total it up = 6460 (approximately)

the actual value being = 6514

The importance of place value is very much underplayed in to-days schools. Practical examples, used to explain the addition based on place value will help better understanding.
we are taught a mechanical way of addition which obscures the basic principle. Memorizing addition values of the single digit numbers and applying them with carry overs helps us only so much as doing a sum correctly. Of-course this is necessary, but try and do your checking by using place value. I am sure you will enjoy the process.

oh so sweet... (typo)

For the love of numbers - D.R.Kaprekar (1)

Once upon a time (January 17, 1905 to be precise), there was born a boy named Kaprekar. He played with numbers like you and I would play solitaire in our pc. Maths was his entertainment. He went on to become a maths teacher and spread the joy and fun of playing with number to others. He was a maths teacher in the beautiful hill town called Devlali or Deolali (1929-1962). A number theory addict, he was invited in many colleges to talk about his unique methods.

He would say of himself:
A drunkard wants to go on drinking wine to remain in that pleasurable state. The same is the case with me in so far as numbers are concerned.
Well ofcourse, many Indian mathematicians laughed at his number theory ideas and called it trivial. After his retirement in 1962 he found it difficult to survive with his pension. He was forced to take maths and science tutions to make enough money.

International fame only came in 1975 when Martin Gardener wrote about Kaprekar and his numbers in his 'Mathematical Games' column in the March issue of Scientific American.

His discoveries in number theory include
Let us make him our hero by entertaining ourself with these fun methods...

Can you imagine...the integers? (student)

If numbers are just numbers and operations (+, -, x, /) just symbols, oh... then maths is really boring.
Well, actually numbers can be imagined as values which make sense. HOW????

I was walking up the stairs with my lil chaaru behind. I had climbed 5 steps and she was still in the first step. Mummy come and hold my hand, lets walk up together. So i came down 4 steps.
Which step am I in? 1st step right.
This is how we should start learning integers, where down, below, back, wrong , etc generally denote the negative value of a number.
The above incident can be numerically written as 5+(-4)=1.

In a snake and ladder game I was in the 15th block. I gained 3 steps in the ladder and fell down by 7 steps. Where am I now. 15+3=18, 18-7=11. Here I have to come down by a total of 7 steps.

Draw the number line in a chart or a paper and stick it next to your bed. Try different jumping actions in the line till you understand the working of negative and positive numbers. 

Whenever you work on the integers, visualise the number line (?), imagine it in your mind. The figure should be stuck in your mind. Remember that zero lies between the positive and negative numbers. Well, Iam sure you know that zero has no value, positive or negative.



There you got it!!!

The "CRAP" principle

A term very interestingly coined by the design course at http://www.colorado.edu/.

The following is my version of the CRAP principle, which can be used in both graphic and web designs.

Contrast contrast brings in visual int rest and focus to the design.contrast can be brought in through fonts, colors and dimensions.a focal point (CVI) can be brought in the design using contrast, which is very essential in guiding the user through the design.contrast should also be balanced. Else it can create chaos.

Repeat repetition is a major factor in UI design to bring in consistency.repetition of elements like font color, header size, layout structure etc., tell the user that they are in the same web site.repetition also goes a long way in brand identity, repeating a particular style, by way of graphics, bylines or quote create a brand recognition.

Align alignment brings in rhythm and grace to the design.print designs like news paper and magazines generally justify the content and have a column alignment web pages favour left alignment and majority have a single column structure.every element in a page should be connected and aligned w.r.t each other. never have elements standing alone.always align a image with captions or baseline text.

Proximity group related design units in close proximity, thereby separating different units of the design.a single unity structure without proper grouping, results in a boring layout.there should be enough white space between one group and the other. maintain consistency in spacing different groups.

UI Basics - Few gudelines


“A good designer knows the user and designs for the user”

The user interface is the aggregate of means by which people (the users) interact with a particular machine, device, computer program or other complex tool (the system). The user interface provides means of:
• Input, allowing the users to manipulate the system
• Output, allowing the system to produce the effects of the users' manipulation.

- Wikipedia encyclopedia

The following list is a compilation of some basic guidelines every designer will follow and some of my personal experiences.

Even before that, there is one point which I would emphasize -
It is not enough if a design is aesthetically pleasing it should also be technically flawless.

1. Know your user and understand their profile (requirement gathering, persona creation and other usability tools)
2. The client is not always the end user. If you feel a certain element is essential in terms of the user, let the client know about it.
3. Follow consistency in terms of placement, color, functionality etc.
4. Make visual cues clear.
E.g. if link text are underlined, do not underline submenus or titles. This will confuse the user.
5. Know how to attract attention. Animated gif or a promotional tool should be attractive at the same time be in sync with rest of the page.
6. Use css and html to give optimum results. Understanding of SEO basics and css2 go a long way in making a good website.
7. Provide Help to the user.
About boxes, help documents, tool tips, visual cues etc (feed back to say action is complete).
8. Visually define the context. Cancel and refresh buttons placed together in a form generally created confusion.
9. Give importance to typography. Defining correct font size for headers, sub-headers and other text help the user to a great extent.
10. Use proper metaphors when you design icons.
11. Use controls effectively. (Radio button, check box etc.)
12. User testing is an absolute essential.

This is not an exhaustive list. Comments and suggestions are welcome.

some key factors...

I was browising through a article in the digital web magazine - "The Business of Blue", by Stephen Van Doren.

Few basic concepts which I thought will be of help to review.

Saturation
is important to strong colour scheme because it is the primary criterion by which a reader or viewer will assess the work. Stronger saturations call for a much louder voice, where desaturated schemes lend themselves to a much lighter touch.

Visibility,
of course, pertains to how the colours "jump" from the page. It is important to note that not all colours need to do this; they can be as transparent as you wish. At the same time, if you place a premium on visibility the choice of colour must be evident to the viewer, or the implied message is lost.

Hierarchy
refers to the levels of colour utilized in a scheme: in each swatch combination, there are three colours.
The first is the primary colour, used in major washing of objects and blocks to give the first "punch."
The second is the subordinate colour, which is used to substantiate the claim the primary colour holds on the viewers attention.
The third the accent colour, which should be used sparingly within reason so that the viewer's eye can jump from place to place to ascertain what is truly important about a particular project.

Stephen Van Doren is a software developer and graphic designer from Denver, Colorado.

Typography and CSS2

CSS1 vs. CSS2

A designers dream will always be to bring some amount of typographic aesthetics into a webpage.
Because the main challenge online is that, people to a great extent tend to scan the content that actually read it. So one has to judiciously use techniques to highlight important text. How different yet technically viable a site can be made in terms of text, will be the top of mind concern for any designer.

With little extra time spent on style sheet authoring, all these can be achieved to a great extent with the CSS2 techniques.

The effect of judiciously exploiting CSS2 can be seen in the following links which Garrett Dimon in his article "CSS Typography" in the Digital web magazine.
http://www.Kottke.org
http://www.RobWeychert.com
http://www.Subtraction.com
http://www.AListApart.com

In CSS1 fonts used were assumed to be in the client's system and were identified solely by name. Alternate fonts were specified through the properties. CSS2 gives the liberty to the author to describe the font that is to be used. And the user to select a font when the author's requested font is not immediately available.

The beauty of CSS2 is that, it defines the information in the client/user agent database and allows stylesheet authors to contribute to it. To display a character with a particular font, the user agent first identifies the "best fit" form the data base. Then retrieves font data locally or from the web to display the character using the particular glyphs.

So in css2 there are basically two mechanisms, font specification by the author and font selection by the user agent.

css2 specifies fonts according to the following characteristics
Font family, font style, font variant, font weight, font stretch and font size.
As a fall back mechanism generic family name is always specified as in css1. The five generic font families are serif, sans-serif, cursive, fantasy and monospace

In font selection by the user agent, there are four possible actions. Font name matching, intelligent font matching, font synthesis and font download.

This is just a snap preview of the concepts. Elaborate details are available at w3c

Who is a UX Designer

Been quite some time since I last visited my blog. Wanted to write about a very interesting discussion over the HCI-IDC group mails. The topic was about the very identity of designers. Who is a UX designer and what is his/her exact profile? Interaction design, visual interface design, information design, usability analyst, IA, emerging tech design are different roles of a UX dessigner. As Mr.Dinesh Katre rightly put it, to claim oneself as a UX designer and not having your fundas right will be over claiming and under performing. A designer according to me should be conversant with at least all the basics and specialize in a couple of UX concepts. Today people who choose this field is luckier that they have these specialized subjects offered at their graduation levels. This gives them more confidence about the subject when they enter the industry. Rather people like me learnt in the process of experience and on a larger scale on requirement basis of projects we worked in. Learning is a ongoing process and one way or other you get into it if you have interest in the subject and wish to improve.

Teak wood carving...

I've been going to this carpenter shop next door and for the past few weeks and understand the way they create/carve the furniture designs. This is Bakur Bose and he's been working on a intricately carved sofa. The models are selected by the customers and the carpenters go ahead with it. Giving here few snaps i've taken during the process...

1. The 3 seater piece assembled

Center of Visual Impact

Imagine yourself reading your daily with that favorite cup of coffee in your hand or browsing through a webpage at free time on your favorite subject. Do you start reading from the left to right, top to bottom, or there is this one thing that attracts your attention first? A colorful photograph or a headline in a comparatively larger font which might not exactly be placed at the left top.
A good designer can actually guide you through the page in a particular way by using different design elements as an attention grabber. This attention grabber is termed as the CVI – Center of Visual Impact, a concept that Mario Garcia writes about in his book Pure Design. CVI is about the use of one visual element that is at least three times larger than others on the page. http://poynter.org/dg.lts/id.33/aid.3251/column.htm
The CVI concept is very important as it plays a major role in shelf visibility of the product. It is not only restricted to News papers or magazines but also proves to be of use in web designing, package designing and Interior designing.
And, yes there should be only one CVI in a page. Else it will lead to confusion.

Of Header and Sub header...

Header and Sub header plays the role of introducing the subject line to the reader. Besides the choice of words or phrasing of the headers, their presentation in a print or web medium has great significance.

The cover design
The main aim behind the cover design is to give a glimpse of what’s there inside thus prompting the reader to buy and browse through. A Serif/Slab Serif is an obvious favorite choice for the title or the name of the magazine. With strong finishing strokes and extensions, these help grab the attention from a distance. Supported generally with a photograph or illustration (very rarely) the cover design template demands attention grabbers. I have rarely seen any magazine follow a standard color pattern on their covers. The color choice will obviously depend on the image the designer chooses. The ideal pattern for the highlight text will be to stick to a single font family with the headers in bold text and the detail text in at least three points smaller in size. Going for different font options or fully upper case creates confusion.

The font size variation (Main text atleast 3points bigger than the rest of the text) plays a important role in the visual appeal of both the cover and the inside pages, be that print or web. I will next talk about a important concept dealing with size variation.

Art 'n Silliguri

After a really long time, I am back to my blog. Moving to Silliguri from Chennai has brought in a lot of changes to my life. What i would like to write here is about the artistic resourcefulness of this place.
Of the many things which intested me here Pottery, Cane furniture and teak wood carving are the most intresting. Very close to Ranidanga where i stay is a place called Matigara, here one will find a row of thached shops on either side of the road with some very intresting and intricate pottery work. Thery have a wide range of products from the common flower pot designd to the most amazing terracotta stuff.One piece which you would find in almost every house here is the winding bell, the wind chime.
Go further down towards Baghdogra airport, again a row of shops with men crafting the best of teak wood furniture.
My next postings will concentrate more on these.

Who Designed the font…?

Verdana was designed by Matthew Carter to be used and read on screen. Carter co-founded Bitstream Inc. in 1981, one of the first digital type foundries, where he worked for ten years. Designed with an eye for both function and aesthetics, Verdana's characters have a large x-height and are widely spaced to ensure that letters don't run together. The font was first released when shipped with Microsoft's Internet Explorer in 1996.

Baskerville is a transitional serif typeface designed by the English gentleman printer John Baskerville in 1757. Baskerville had also mastered the craft of engraving headstones, a knowledge that influenced his design process. His letters are sharply detailed with a vivid contrast between thick and thin elements. During his lifetime, Baskerville's letters were denounced as extremist, but today we think of Baskerville as a classic, elegant, and easy to read font. Baskerville's lifestyle was also regarded with suspicion: he was a professed agnostic living out of wedlock (see Mrs Eaves).

Bodoni , created by Giambattista Bodoni in the 1790s, is known as a modern typeface. It has nearly flat, unbracketed serifs, an extreme contrast between thick and thin strokes, and an overall vertical stress. Compared to Garamond, which is based on handwriting, Bodoni is severe, glamorous, and dehumanized. Similar typefaces were also designed in the late eighteenth century by François Ambroise Didot and Justus Erich Walbaum.

Caslon is named for the British typographer William Caslon, whose typefaces were an eighteenth-century staple and a personal favorite of Benjamin Franklin (who also enjoyed the racier innovations of John Baskerville). The U.S. Declaration of Independence and the Constitution were first printed in Caslon's types. Classified as transitional, Caslon has strong vertical elements and crisp serifs. Adobe Caslon, designed by Carol Twombly in 1990, transports Caslon's solid Anglo pedigree into the digital age.

Centaur was designed by Bruce Rogers between 1912 and 1914, inspired by the work of the fifteenth-century Venetian printer Nicolas Jenson. Emphatically calligraphic, Centaur is paired with the italic Arrighi, designed by Frederic Warde. Centaur was commissioned by the Metropolitan Museum of Art for printing the museum's ephemera. It is called Centaur because it was used in a 1915 publication of Maurice de Guerin's poem of the same name.

Century Expanded was created in 1900 by Morris Fuller Benton, who was trained as a mechanic and engineer and became a leading designer during the early years of the American Type Foundry. The Century family is so called because it was initiated by Morris's father, Linn Boyd Benton, for Century magazine. Classified as Egyptian owing to its slab serifs, Century Expanded maintains its substance and openness at small sizes. It is often used in children's books.

Clarendon, named for The Clarendon Press that commissioned its design in 1845, is classified as an Egyptian typeface. It has heavy, slab serifs and ball terminals on the arms of some letters. This stocky, functional, Victorian face can be seen in early advertisements as well as in dictionary entries.

HTF Didot was created by Jonathan Hoefler in 1992, inspired by the late eighteenth-century designs of Francois Ambroise Didot. It has an overall vertical stress, extreme contrast from thick to thin, and unbracketed serifs. Hoefler created different styles for use at different sizes, enabling the typeface to maintain its distinctive character across wildly divergent scales, from enormous letters on the side of a bus to tiny text on the pages of a magazine. Each font is represented by a number that lets the user know the smallest point size at which it should be used.

Fedra Sans was designed by Peter Bilak in 2001. Bilak was commissioned by Reudi Baur Integral Design to develop a corporate face for the German insurance company Bayerische Rück. The design brief required a "de-protestantized Univers." Bilak, a Czech-born designer working in the Netherlands, sought to create a face that would work equally well on screen and on paper, and at both small and large sizes. The Fedra type family includes at least 35 variations.

Franklin Gothic, designed in 1902 by Morris Fuller Benton for the American Type Founders , is one of the most popular sans-serif types ever produced. Named after Benjamin Franklin, it is a weighty sans-serif font often used for headlines. ATF later gave ITC permission to create additional weights for the Franklin Gothic family. Matthew Carter created a refined version of Franklin Gothic for use in the graphic identity of the Museum of Modern Art, New York.

Futura was designed by the German typographer Paul Renner in 1927. This geometric sans-serif font embodies Bauhaus ideals in a practical, commercially viable typeface. Futura has round O's and a capital M, N, and W with sharply pointed peaks and valleys. Renner, who viewed Futura as an appropriate typeface for the machine age, streamlined the alphabet by eliminating the tail from lowercase t and j.

Georgia, designed by Matthew Carter in 1996, is the serif companion to his sans serif font Verdana. Commissioned by Microsoft and created specifically for on-screen reading, it maintains clarity at small sizes and at low screen resolutions. It has a more vibrant character and open quality than Times, another common default face for Web designers.

Gill Sans was created by the English designer Eric Gill in 1928. Its forms are more humanistic, less geometric, than its German contemporary Futura. Note how the lowercase a relates to the a in Garamond (in contrast to the circular a of Futura). Additionally, Gill Sans is recognized by its flared capital R and the closed descender of the lowercase g. Gills Sans has been called Britain's Helvetica; it remains today an overwhelmingly popular typeface across the United Kingdom.

Garamond is the name for typefaces based on pages printed by Claude Garamond in sixteenth-century France. Many versions of Garamond were created in the twentieth century, including Adobe Garamond, designed by Robert Slimbach in 1989, and ITC Garamond, a distinctly 1970s version with a grossly enlarged x-height. Adobe Garamond honors the proportions of its Renaissance source while translating the face for modern use. Note the elegant, three-dimensional bowl of the lowercase a and the gap in the uppercase P.

Helvetica was designed in 1957 by Max Meidinger. This deliberately anonymous typeface is one of the world's most commonly used fonts, with variations created for both Latin and non-Latin characters. Its solid, upright forms are tempered by surprising curves in the lowercase a and the uppercase R. Helvetica has a generous x-height and is available in numerous weights and styles. It was called Neue Haas Grotesk before getting its current name, Helvetica, in the early 60s, which is the Latin word for "Switzerland."

News Gothic is a solid sans-serif face designed by Morris Fuller Benton in 1908. It is similar to Benton's other sans serifs, Franklin Gothic; and Alternate Gothic. The caps in News Gothic have a relatively uniform width, and the lowercase forms are compact and powerful.

Trade Gothic was designed by the American designer Jackson Burke between 1948 and 1960 for Linotype. Similar in character to nineteenth-century grotesques and twentieth-century staples like News Gothic, Trade Gothic has a large x-height and excellent condensed variants. Often used for newspaper headlines, Trade Gothic is tough, direct, and generic.

Ideal Line Lengths - a core usability issue

I happened to browse through one of the blogs today. The subject was pretty interesting, but there was no column separation whatsoever. The text runs from the extreme left to the right making the reading experience quite tiring. It is importance to understand the benefits of having a ideal line length for the content.

Well I am again comparing the print and the web. In print, be that magazines, books or newspapers the column width is maintained for comfortable reading. This has scientific reasons. At normal reading distances, your eyes can comfortably span an acute focus of only about 3 inches width. A 30-40 character per line is considered to be ideal in print layouts, so that you have a comfortable eye span focus.

In web, there is no fixed screen width. When the design is a fixed width layout, things are easier to control to a certain extent. But when you have a liquid layout, the alignment changes with the resolutions the user sets in his computer. Imagine a 1024 resolution with your content running from left to right! Not very interesting right?. A designer can control the width in a liquid layout using css. But its not foolproof.

The discussion about fixed vs. liquid layout has been going on for a long time with each on having their merits and shortcomings, with browser compatibility being one of the major concerns.

Lets be conscious of how we display our the content and make online reading a pleasant experience.

Typeface in the New Business Line

First it was the Hindu redesign on April 14th last year, Mario Garcia has now proved it again with the redesign of Business Line. The financial daily by the Hindu, unveiled its new design on Feb 14, 2006.And Frontline, a bi-weekly magazine published by The Hindu, gets its new look on March 2. And what is of interest to us besides the design aspects is the typeface used.
Mercury Display, Mercury Text, various weights of Griffith Gothic and Big Caslon are the type faces used by Mario Garcia and his team for the news paper.
Mercury as research suggests uniquely suits to the demands of editorial typography.

Griffith Gothic An interesting fontface with 18 styles, Griffith Gothic is recommended for Newspapers, Magazines and Branding & Identity.

Big Caslon Caslon’s text types have often been revived, but the display sizes, forceful and a touch eccentric, have had no digital version until Matthew Carter’s Big Caslon. The face is meant for use at eighteen point & above.
Among other uses this fontface is highly recommended for magazines.

Welcome Change for good!!!
Hopefully I get sometime during this weekend to ponder into the design aspects and usability of this new avatar :)

Type Classification

Trying to understand the charecteristics of a font face, i've been going through a lot of books and sites. Though there are innumerable classifications, there are 9 broad categories which give a better understanding of the subject. I am not going to dwell in detail about them here, rather will give few useful links.
1. Humanist
2. Garalde
3. Transitional
4. Didone
5. Slab-serif
6. Lineale
7. Glyphic
8. Script
9. Graphic / Decorative
