Lost in cyberspace

You only have to be the parent of a child over the age of seven to know what I’m talking about: the vacant eyes so preoccupied by what’s on screen that they can’t focus on your face for more than a few seconds before being drawn back into the cyberworld.

As you talk, your little darling types or toggles. “Are you listening to me?” you ask, only to be told in a precocious tone: “Yeahhhh. I’m multitasking, Mum.”

How Microsoft’s Xbox 360 & Kinect Help Surgeons in the OR

The sight of a surgeon playing “Grand Theft Auto” in the operating room might raise eyebrows, but it’s one example of how consumer technology is being repurposed to advance the practice of medicine.

Rising medical costs — bloated by expensive, complicated machines — are wrecking the nation’s economic health, while off-the-shelf consumer gadgets keep getting cheaper and more powerful. So the health care industry has discovered it can tap into the innovative wonders of an Xbox 360 or PlayStation 3 or an Android smartphone app.

Sony Predicts Return of Virtual Reality

July 5, 2011

Not content with attempting to usher in the advent of 3D console gaming, it seems Sony now has its sights set on the next quantum leap – virtual reality.

Speaking in a video interview to promote next month’s b.tween 3D event in London, SCE Studios exec Mike Hocking explained that Sony’s recently announced HMD device could represent the future of 3D gaming by allowing users access to a full ‘virtual’ world.

2011 E3 Coverage: New Wii, Kinect Games and PS Vita

June 7, 2011

New Nintendo Wii, Star Wars Game Using Microsoft’s Kinect, and PlayStation Vita Portable

Coverage update from the world’s leading video game conference: the E3 Expo in Los Angeles

Situated Research is bringing you the hot news from the world’s largest annual video game conference, the E3 Expo, which began this week in Los Angeles. So far, Nintendo has announced it’s next-generation console, called the Wii U, and Sony has launched a new handheld called the PlayStation Vita. Microsoft has announced some interesting new games for the Kinect, including Star Wars, Disneyland Adventures, and Halo 4.

Utilize Available Screen Space

May 9, 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.

BrainDriver: A Mind Controlled Car

March 23, 2011

Imagine you could drive your car using only your thoughts. German researchers have just made that possible – and they have the video to prove it. Following his recent interview on the Robots Podcast about autonomous vehicles, Raul Rojas, an AI professor at the Freie Universitat Berlin, and his team have demonstrated how a driver can use a brain interface to steer a vehicle.

For IBM’s Watson technology, What Happens After “Jeopardy!”?

IBM’s Supercomputer Has Implications for Healthcare, Information Tech and More

Wouldn’t it be nice to have your very own supercomputer in your pocket?

If your laptop crashed while you were working on a major presentation, you could ask your portable expert to help diagnose the problem. If you wanted to bone up on Middle Eastern history, you could ask it to comb every document available and then wrap it all up in a simple summary (annotated, of course).

Kinect Gestural UI: First Impressions

December 30, 2010

Read the manual before using the interface. (Kinect Adventures)
(Yes, it’s a *cute* manual, but these are still instructions to memorize.)

Summary: Inconsistent gestures, invisible commands, overlooked warnings, awkward dialog confirmations. But fun to play.

Kinect is a new video game system that is fully controlled by bodily movements. It’s vaguely similar to the Wii, but doesn’t use a controller (and doesn’t have the associated risk of banging up your living room if you lose your grip on the Wii wand during an aggressive tennis swing).

Why You Only Need to Test with 5 Users

November 15, 2010

Some people think that usability is very costly and complex and that user tests should be reserved for the rare web design project with a huge budget and a lavish time schedule. Not true. Elaborate usability tests are a waste of resources. The best results come from testing no more than 5 users and running as many small tests as you can afford.

In earlier research, Tom Landauer and I showed that the number of usability problems found in a usability test with n users is:

N(1-(1-L)ⁿ)

where N is the total number of usability problems in the design and L is the proportion of usability problems discovered while testing a single user. The typical value of L is 31%, averaged across a large number of projects we studied. Plotting the curve for L=31% gives the following result:

The most striking truth of the curve is that zero users give zero insights.

Castlevania: Good Usability, Poor User Experience

October 20, 2010

Konami recently sent us a copy of their new title, Castlevania: Lords of Shadow. After testing the game, it was clear that the game could be a case study to highlight the difference between usability and user-experience (UX).
