Browser and GUI Chrome

January 30th, 2012
Summary: “Chrome” is the user interface overhead that surrounds user data and web page content. Although chrome obesity can eat half of the available pixels, a reasonable amount enhances usability.

What do we mean when talking about the “chrome” in a user interface design? An attendee asked this question during a recent course on Visual Design for Mobile and Tablet. Whenever someone asks us a basic question, I assume that many more people want the answer as well — and thus, this article on chrome.

  • Definition: Chrome is the visual design elements that give users information about or commands to operate on the screen’s content (as opposed to being part of that content). These design elements are provided by the underlying system — whether it be an operating system, a website, or an application — and surround the user’s data.
  • Not coincidentally, “Chrome” is also the name of Google’s web browser, though I don’t use the term in that sense here.

I don’t know who came up with the term “chrome,” but it was likely a visual analogy with the use of metal chrome on big American cars during the 1950s: the car body (where you sit) was surrounded by shiny chrome on the bumpers, tail fins, and the like. Read more »

Overloaded vs. Generic Commands

December 28th, 2011
Summary: Overloading different outcomes on similar commands can be confusing. Using the same command for multiple actions enhances usability if the results are conceptually the same.

One way to manage interaction design complexity is to have commands serve double duty. There are two ways of doing this, with different usability implications:

  • Generic commands use the same command in different contexts to achieve conceptually the same outcome, even though details of the specific effects might differ.
  • Overloaded commands use variants of the same command to achieve different outcomes — sometimes depending on the context and other times depending on where the command appears on the screen.

I discussed generic commands in depth in an earlier article. The most famous generic command these days is the pinch-zoom gesture, which works in most touchscreen user interfaces. In fact, the command is so pervasive that users expect it to work universally — and are sorely disappointed when they encounter an application that doesn’t support it. Read more »

Invoked Computing: Device-free Ubiquitous Augmented Reality

December 15th, 2011

invoked computing Invoked Computing: Device free Ubiquitous Augmented Reality
A research group at the University of Tokyo are creating a new paradigm in Human Computer Interaction. Dubbed ‘Invoked Computing’ the idea is to turn everyday objects into computer interfaces and communication devices.

“For example, if you make a gesture, the computer should be able to recognize this as “I want to use the telephone”. So with an iPhone for example, you have everything in a small device and you have to learn how to use it, here we want to do the opposite, the computer will have to learn what you want to do.” Read more »

Accuracy vs. Insights in Quantitative Usability

November 30th, 2011

Summary: Better to accept a wider margin of error in usability metrics than to spend the entire budget learning too few things with extreme precision.

Last week, I made a slide for the new User Experience (UX) Basic Training course with the recommended number of test users for different types of studies. I like teaching foundational courses because they afford me just this kind of opportunity — to distill 25 years of usability process research into a single table. Patterns crystallize when complex topics are condensed to the essence. Read more »

Microsoft’s Vision for Future Productivity

November 12th, 2011

From Microsoft’s Office YouTube Channel:

Watch how future technology will help people make better use of their time, focus their attention, and strengthen relationships while getting things done at work, home, and on the go. (Release: 2011)

There are some interesting concepts in the video involving augmented reality (adding visualizations to one’s environment), new user interfaces and user collaboration, and “Web 3.0″ style communication: where relevant information finds the user at the appropriate time (an intelligent filtering of the overwhelming information now being generated by “Web 2.0″ technologies such as social media).

OmniTouch turns body parts and nearby surfaces into touch interfaces

Multitouch screens are so versatile and easy to use, why limit them to smartphones and tablets? Researchers have been working for several years to extend multitouch to arbitrary surfaces, but a project called OmniTouch from Microsoft Research and a PhD student at the Human-Computer Interaction Institute at Carnegie Mellon University may bring it closer to reality.

How Long Do Users Stay on Web Pages?

September 12th, 2011

Summary: Users often leave Web pages in 10–20 seconds, but pages with a clear value proposition can hold people’s attention for much longer because visit-durations follow a negative Weibull distribution.

How long will users stay on a Web page before leaving? It’s a perennial question, yet the answer has always been the same:

  • Not very long.

The average page visit lasts a little less than a minute.

As users rush through Web pages, they have time to read only a quarter of the text on the pages they actually visit (let alone all those they don’t). So, unless your writing is extraordinarily clear and focused, little of what you say on your website will get through to customers. Read more »

Next Generation Technology for Full Body Game Controllers

September 7th, 2011

MRC Next Generation Technology for Full Body Game Controllers
Patent approved for Motion Recognition Clothing(TM)

Medibotics’ U.S. patent 7,980,141 for Motion Recognition Clothing™ (MRC) has been approved. MRC is an innovative technology for translating body motion into computer-readable signals that could power the next generation of full-body game controllers. The market for translating body motion into computer-readable signals is already very large. For example, over 10 million units of an existing camera-based full-body game controller system have been sold. With further development, MRC could be used for a variety of applications including not only computer gaming, but also virtual reality in general, sports training, medical therapy, virtual exercise, weight management, and telerobotics.

Sony Says Games Will Read Emotions in 10 Years

August 28th, 2011

HAL90001 Sony Says Games Will Read Emotions in 10 YearsSony is talking crazy, indicating that games may be able to tell if you’re lying or depressed just ten years down the road. We’ll stick with growing crops, thanks.

Seriously, when do games stop being games and cross over into virtual reality? This was the question I asked Nvidia months ago at ECGC 2011, and was told there will always be a market for the high-end PC gamer with the rig nearly the size of a bookcase. But putting visual realism aside, what will happen when games suddenly stop acting like games, and become more like a self-aware super AI that could possibly one day sing you happy birthday or annihilate the human race?

aeon The Aeon Project: AR & Virtual Reality In Vehicles

Designers Michaël Harboun, Fabien Chancel and Akki Reddy Challa have been working in collaboration with Dassault Systems to explore augmented reality inside vehicles. In the future, when our cars are autonomous and can drive themselves, Harboun and his colleagues have been questioning what we’ll be doing while travelling along. The Aeon Project features three levels the user can select from the heads up display (HUD): augmented reality, mixed reality and virtual reality. So they can choose from text information, 3D integration and complete virtual immersion. Read more »

You are playing a video game, and your avatar is creeping into a haunted house at the dead of night. Suddenly, you freeze in your chair. Something is crawling up your back…

Whether this idea appeals or not, researchers at Disney have made such sensations possible by inventing a system that fools players into thinking that objects are moving against their skin. Read more »

Utilize Available Screen Space

May 9th, 2011

Summary: Websites and mobile apps both frequently cram options into too-small parts of the screen, making items harder to understand.

A computer screen’s precious pixels are the world’s most valuable real estate. Amazon’s Add to Cart button is 160×27 pixels, or 0.003 square feet (0.0003 m2) at a typical 100 dpi monitor resolution. You could crowd almost 800,000 Buy buttons onto the floor space of the average American home, which currently sells for $160,000. Even a single Buy button will often bring in more than that — let alone the revenue from 800,000 buttons.

Normally, when something is extremely valuable, you try to conserve it. But screen space shouldn’t be hoarded, it should be spent. I see too many designs that cram highly valuable content or action items into tiny spaces while wasting vast amounts of screen space. Read more »
