Fantasy HCI! Dream Lab and Dream Team for the Future

Fantasy HCI!

My wish is to have my own lab so I can create and test out various interactive applications that run on screens of all sizes, and play with new interactive gadgets and displays. I'd also like to provide mobile lab services so I can go out and see how emerging technologies play out in real-life situations and settings during the design & development process as well as after-market.

I'd like to focus on social-collaborative & cognitive aspects of emerging technologies. Because of my background in school psychology, I'd work towards ensuring that new applications, technologies, and systems follow the guidelines of Universal Design for Learning as well as Universal Usability. I have some ideas about the transdisciplinary characteristics I'd like to see for members of the lab's Dream Team, but I'm saving that for another post. Now I just need to win the lottery so I can hire my team and run with the ball. Team Charlotte, N.C., anyone?

Digital Photography - off topic

This picture was taken in the mountains of Norway, not too far from Flam and the nearby fjords with my digital camera. Peaceful.

I've been observing people of all ages using technology durng my trip, within the context of wayfinding, communication, usability, and user experience, and I'll be posting more when I return.

Usability, Accessibility, and User Experience in a Win7 Environment

Microsoft's newest operating system, Win7 (beta), allows for multi-touch interaction and application development. From what I can tell from the news from the Consumer Electronic Show (CES 2009), touch and gesture interaction holds quite a bit of interest among consumers and application developers alike.

Hopefully people will think carefully about user experience and usability factors when developing the applications we'll be using in the not too distant future!

Because of my background as a school psychologist, I’m interested how touch/gesture applications can address accessibility and universal usability issues.

I wasn't able to locate user experience or usability information for Win7. Here are a few links from the Microsoft website that I think are worth reading:

Touch Interaction Guidelines

How to Design a Great User Experience

Designing with Windows Presentation Foundation

Accessibility

According to the research from Microsoft, ”more than half of all computer users experience difficulties or impairments related to accessibility, and are likely to benefit from the use of accessible technology. Moreover, approaching software design with the flexibility and inclusiveness that are the hallmarks of accessibility often results in overall improved usability and customer satisfaction.”

Regarding touch/gesture interaction, know that “19% (24.4 million) of computer users have a mild dexterity difficulty or impairment, and 5% (6.8 million) of computer users have a severe dexterity difficulty or impairment.”

Christian Moore, from the NUI-Group, shared this nice graphic that depicts the various fields that intersect or converge with interface design, which I think is useful when thinking about how we will design, develop, and use emerging technologies:

Concepts such as accessibility and universal usability can fit into this design!

The Internet of Surfaces? Microsoft's Pete Thompson discusses screens and surfaces of all sizes.

I came across this video of Microsoft Surface's general manager, Pete Thompson, on the GottaBeMobile website. According to Thompson, the people who worked with TouchWall discussed in the video, were also involved with Microsoft Surface.

Apparently, the Surface and Wall folks at Microsoft aren't sure of what they are doing with screens of all sizes.

(If you are interested in surface form factors, see my previous blog post, Emerging Interactive Technologies, Emerging Interactions, and Emerging Integrated Form Factors.)

There are many unanswered questions from my perspective.

Bill Gates portends that every surface will be a computer, a concept that is echoed in the video. If so, what are people doing to ensure that surface-supporting environments are universally designed?

Before Microsoft and other companies unleash "surface" technology to the masses, they must get a few things right.

Will they?

Will the researchers at Microsoft find out how various screens play out in classrooms, in the community settings, on-the job, and in-between?

For example, large interactive displays in urban and retail settings have the potential to provde people with a rich amount of information about what is around them. These displays serve little purpose if they are user-unfriendly, and no purpose at all if they are not accessible.

If developers and designers are not following basic user-centered design guidelines and usability standards now, how can we expect the nextgen systems of display surfaces to support universal usability? As our population ages, this will be more of a problem.

From what I can tell, there will be more opportunities for people to use their mobile devices to interact with larger screens and surfaces when they are out and about. For example, when I was at the airport recently, I noticed that there was a large display that offered cell-phone ringtone downloads. Microsoft was behind this display.

Interconnectivity and interoperability between devices and screens of all sizes is important to think about. If universal usability guidelines are not followed, our mobile devices will be difficult to use in the world of surfaces.

It isn't much of a leap to see the big picture. Just think about the problems we have with our remote controls and entertainment centers in our homes! We might have to carry all sorts of devices just to get from point A to point B. I'm not kidding. It will not be a pretty sight, especially if the privacy and security issues are not resolved as we move to a world that supports the internet of things.

Or shall I say, the internet of surfaces?

Technology Supported Human-World Interaction Blog

I've started another blog: Technology Supported Human-World Interaction (TSHWI)

"TSHWI is about the development of newer technologies that support human-world interaction. This concept incorporates the best of of HCI, CSCW, universal usability, interaction design, game design, educational technology, and Ubicomp/ Pervasive Computing. The definition of "World", can include virtual worlds, simulations, VR, or augmented reality - just about anything humans interact with in their daily lives."
