7 javablogs Recent Entries Motivation

Data Structures in Java/C++

In his book, 7 Habits of Highly Effective People, Stephen Covey tells the story of a woodcutter who took a new job for a timber merchant. The woodcutter was determined to do his best, so when the employer presented him with an axe he went straight to work. The first day the woodcutter brought 18 trees to the boss. “Congratulations,? the boss said. “Keep it up!? With this motivational encouragement the cutter went out the next day with even more determination. However, at the end of the day he could only bring back 15 trees. The third day he worked harder still, yet try as he might only 10 trees could be felled. So it went; each succeeding day yielded fewer trees. “I must be losing my strength,? the woodcutter thought. He decided to approach his boss to apologize for his unexplained deteriorating output. “When was the last time you sharpened your axe?? the boss asked. The woodcutter stared dumbfounded. “Sharpen my axe! I had no time to sharpen my axe. I have been too busy trying to cut trees!?

It is possible to be too busy to maintain your effectiveness. Whatever your personal situation, this might be the right time to ask yourself if it is time to “sharpen your axe.?

They have a manifesto on the web site that reads: “Most places on Earth, the Internet is more accessible than electricity, clean water, or basic sanitation. That's an amazing proliferation, and an outstanding opportunity to apply simple technologies to some of the world's most pressing problems. We're setting out to do exactly that, focusing on the intersection of innovation and public health.?

22 javablogs Recent Entries How to build the perfect Android tablet, part 4: Resolution and aspect ratio

Ed Burnette's Dev Connection Blog RSS | ZDNet

The perfect tablet should be wide enough to view typical web pages in landscape mode, but not so wide that it looks weird when turned on its side. Here’s how to pick the right compromise.

23 PlanetEclipse Feeds from Planet Eclipse Blogs Ed Burnette: How to build the perfect Android tablet, part 4: Resolution and aspect ratio


In part 2 of this series I stressed the importance of a responsive multi-touch screen to the success of upcoming Android tablets (or any tablet shaped device that competes with the iPad). For this installment I want to return to the display and discuss a different, um, aspect with you. My pick for the 4th most important feature of the perfect tablet is:

#4: A high resolution display that is wide but not *too* wide

One of the top reasons to have a mobile internet-capable device, be it a tablet or smart phone, is to browse the web. Unfortunately the web doesn’t look so great on most mobile displays unless the web site has been specifically formatted for the small screen. The reason is that the vast majority of web sites were created for desktop and laptop monitors which are both wide and tall.

What is the resolution of the monitor you are using right now? You’re probably using it in landscape mode, which means the width is more than the height. According to one site, 96% of web users in 2010 have a display which is 1024 pixels wide by 768 pixels tall or bigger, and 69% use displays that are at least 1280 pixels wide. Web developers design their sites to look good on the majority of screens, so most web sites expect at least 1024×768. If you screen is smaller than that, then the result can often be hard to read. Either the text is too small, or you’ll have to do a lot of scrolling to see it, or both.

For example, one of the sites I frequently visit is dzone.com (I used to run an Eclipse forum for them a few years ago). Unfortunately the site is almost unusable on my Nexus One, which has a resolution of 800Ă—480. Try viewing this page on your phone to see what I mean. I know that with proper use of style sheets you can design a site that will be friendly to many different resolutions, but flexible sites like that are few and far between. Therefore, for best results on the real web, a width of 1024 pixels is pretty much the minimum you should accept in a tablet.

How about height? The ratio of width / height is called the aspect ratio. There’s a great chart on Wikipedia showing all the standard aspect ratios, but here are some common screen sizes and ratios you might be familiar with:

DeviceResolutionRatio
Nexus One800Ă—4801.67 (5:3)
Droid 2854Ă—4801.78 (16:9)
iPhone 4960Ă—6401.5 (3:2)
Samsung Tab1024Ă—6001.71
iPad, older laptops1024Ă—7681.33 (4:3)
TV Hi-def 720p1280Ă—7201.78 (16:9)
Apple MacBook1280Ă—8001.6
MacBook Pro1440Ă—9001.6
WSXGA+1680Ă—10501.6
TV Hi-def 1080p1920Ă—10801.78 (16:9)
Theatrical standardn/a1.85
Anamorphic wide screenn/a2.39

Clearly, a 1.78 ratio (16:9) or higher would be ideal for watching movies. But movies probably aren’t the only thing you’re going to do with the device. Remember web browsing? How about using it in portrait mode for reading books or running games? A very wide screen turns into a very tall screen when you rotate it 90 degrees. The all-purpose nature of tablets is probably why Apple chose an old-school 1.33 (4:3) ratio for the iPad. But having used the iPad for several months, I think they went a little too far. On the other extreme, my Droid seems a little too tall for portrait work. Therefore my perfect tablet will have a screen aspect ratio somewhere between 1.5 and 1.7.

Interestingly, the “golden ratio” is 1.618, which is right in the middle of my range. Who am I to argue with centuries of artists, architects, and mathematicians? Given a width of 1024 or 1280 pixels, and factoring in commonly available LCD panel sizes, I recommend picking one of the following screen sizes for your new tablet:

1024Ă—600: A little on the wide side for my tastes, but should be adequate for web browsing.
1280×800: Tall enough to watch 720p video without scaling, and wide enough for any web site you’re likely to encounter.

To summarize, avoid tablets that are 800 or even 854 pixels wide or less. I’m not saying they won’t be functional and useful for some purposes, but we’re talking perfection here, folks. Also, I’d avoid anything much above 1280 for now. Without zooming, you’ll find that most of the web sites out there on the net will be too tiny to read.

Finally, don’t get fixated on the 1.78 (16:9) ratio just because High Definition TV uses that. A little letterboxing while watching Avatar is a small price to pay for a much more generally usable device that can be viewed in any orientation. Your TV doesn’t have to work on its side in portrait mode, but your tablet does.

See all the articles in the “Perfect Android Tablet” series:

  1. Long lasting battery
  2. Capacitive multi-touch
  3. Android Market and friends
  4. High resolution

What would you build into *your* perfect Android tablet? Share your thoughts in the comment area below. Next week I’ll have one final feature idea to share with you.
