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.
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.
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.
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.
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).
Matthew Sharritt, President of Situated Research, has an article titled “Designing Game Affordances to Promote Learning and Engagement” appearing in a special issue of the Cognitive Technology Journal. The issue, focusing on “Games for Good”, contains our article (starting on p. 43).
When Glenn Harrington donned a motion capture suit complete with more than 40 reflective spheres he wasn’t being turned into the latest video game character, but helping to design car manufacturing jobs that are less physically stressful on workers.
Rockstar Games was nice enough to send us a copy of Red Dead Redemption to try out. After spending time playing the game, we recommend grabbing a copy.
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.
This list of ten features should be embraced by game designers
Steve Krug argues in his book Don’t Make Me Think! that a good program or product should let users accomplish their intended tasks as easily and directly as possible. The less time it takes a person to complete a desired task (even if only by a few seconds), the more satisfying it becomes. When that happens, people are more likely to use a product in greater frequency and return for more. So in the spirit of improved usability, here are ten standard features every videogame designer should embrace.
