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.

Utilize Available Screen Space

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.

Kinect Gestural UI: First Impressions

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

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.

GameFlow and Gameplay in Madden NFL ’11

As a fan of football games, going back to the days of classics like Tecmo Bowl (NES), we were excited to play this year’s redesign of the successful Madden NFL series. We can report that Madden NFL ’11 is the most realistic, graphically stunning, and holistic football simulation to date. However, the new “GameFlow” play calling system has many hardcore Madden fans up in arms, due to the departure from classic play calling in football games. We will discuss some of the new features in Madden NFL ’11, why GameFlow is a step in the right direction, and some features that could be improved for next year’s release of Madden NFL.

What’s Wrong With the RITE Method?

A critique of a common method used in video game usability research

Many video game usability practitioners employ a method to test usability within video games, called the ‘RITE’ method, short for Rapid Iterative Testing and Evaluation (RITE). Pioneered at Microsoft Games Studios and Microsoft Research, the RITE method has been adopted by many usability research organizations besides the teams at Microsoft.

While the RITE method has some advantages, such as the ‘rapid iterative’ ability to suggest changes to designers and test them in successive passes, it may fall short when looking for usability issues that lie beneath the surface.
