Video Game Teaches Blind People to Navigate Buildings

Image: Rendering of physical environment represented in the AbES software; in gamer mode, the player (yellow icon) navigates through the virtual environment using auditory cues to locate hidden jewels (blue squares) and avoid being caught by chasing monsters (red icons).

Blind people can learn the spatial layout of an unfamiliar building using a novel “video game” virtual reality environment that employs only audio-based cues, thus enabling them to learn skills that may improve functional independence, say US and Chilean scientists.

Teaching Video Game Characters Natural Body Language

Video game characters with natural responses to human body language

Researchers at Goldsmiths, University of London have been using theater performers to design computer software capable of reading and replicating the way in which humans communicate with their bodies.

Dr Marco Gillies from the Department of Computing has made virtual characters more believable by enlisting actors to teach them body movement. The actors interact with members of the public through a screen, and their responses to specific body language are memorized as algorithms by the software.

Why Country Sites Are So Bad

Summary: When a multinational company produces a localized country site, usability is often lost. Local advertising agencies design good-looking sites that don’t communicate.

Something was gnawing at me as I observed our last several rounds of international usability studies. Many of the websites we tested around the world had uncommonly low quality — not unlike what we saw in the United States during the 1990s.

Reflecting on this observation, I realized that the worst sites were usually not the truly local sites designed by local businesses or government agencies. Instead, the offenders often came from huge multinational corporations that fielded country sites with horrible usability.

Finding Out What They Think: A Rough Primer To User Research, Part 2

[The following is the second of two articles by college professor and researcher Ben Lewis-Evans on games user research methodology (see Part 1, which covered focus groups, heuristics, and questionnaires, as well as giving a grounding in the topic of user research in general. In this article, Lewis-Evans covers interviews, observational methods (including think out loud and contextual inquiry), game metrics, and biometrics.]

Interviews

Much like a questionnaire — a topic covered in the last installment — an interview is for collecting subjective data. However, the face-to-face nature of an interview means that you can be more interactive in your data collection, which if done correctly, can lead to very rich data. However, it is also obviously quite time-consuming, and it is harder to analyze and quantify the data you get at the end.

The quality of what you get out of an interview will also depend greatly on your own skill as an interviewer, so here are some tips.

Gesture Control System Uses Sound Alone

SoundWave lets an ordinary laptop function like a Kinect sensor.

When you learned about the Doppler Effect in high school physics class—the wave frequency shift that occurs when the source of the wave is moving, easily illustrated by a passing ambulance—you probably didn’t envision it helping control your computer one day.

Finding Out What They Think: A Rough Primer To User Research, Part 1

[In this first article in a new series, college professor and user research Ben Lewis-Evans takes a look at different methods of game user research, offering up a handy guide to different ways you can collect useful information about your game.]

This article, and its forthcoming followup, is intended to give a rough idea to developers of several different methods that can be used in games user research.

However, many, many books have been written on research methodology and I cannot cover everything. Therefore these two articles cannot be taken as completely comprehensive.

In the first of the articles I will be covering a few general points about Games User Research and then discussing three methods, focus groups, heuristic evaluation and questionnaires in some detail.

Creating the Illusion of Emotion or Why You Care About Ones and Zeroes

As much as you may love video games and the stories they help you tell, it’s impossible to escape the fact that much of your experience is a trick of the mind.

The thing that separates video games from other forms of media, the ability to interact with and perhaps shape a virtual world, is mostly powered by the artificial intelligence of the characters that populate that experience.

But at its best gaming artificial intelligence systems, AI expert David Mark says, are, like 2-year-olds, basically sociopaths. What he means is that they are intrinsically anti-social. Getting past that problem doesn’t mean imbuing a character with personality, it means tricking gamers.

Browser and GUI Chrome

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.

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.”

Accuracy vs. Insights in Quantitative Usability

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.
