Call for Participation

The AmI-12 conference brings together researchers and practitioners from industry and academia working in the field of technologies and applications of Ambient Intelligence. Ambient Intelligence represents a vision of the future where we shall be surrounded by invisible technological means, sensitive and responsive to people and their behaviors, deliver advanced functions, services and experiences. Ambient intelligence combines concepts of ubiquitous technology, intelligent systems and advanced user interfaces putting the humans in the center of technological developments.

Authors are invited to submit manuscripts of original unpublished work in all areas related to Ambient Intelligence. Contributions are solicited from, but not limited to the following topics:

objects, devices and environments that embody ambient intelligence
context models and context factors
sensing and reasoning technology
natural and multimodal interaction styles and user interfaces
advanced interface artifacts
end User Development for Ubiquitous Environments
adaptation in Ambient Intelligence
multi-device Interaction
security, privacy and trust
ambient intelligence services
business model and business cases
knowledge-based systems, computational intelligence

autonomic systems, multi-agent architectures and systems
adaptive architectures, symbiotic systems
industrial and commercial applications of ambient intelligence
configuration and control of ambient environments by end-users
user experience and user experience factors (e.g., acceptance)
ambient intelligence for special target groups
ambient intelligence applications (e.g., assisted living, future shopping)
artifacts in ambient intelligence environments (e.g., robots)
large scale ambient contexts (e.g., intelligent buildings, urban public spaces, smart cities)
social media applications in ambient environments
societal implications of ambient intelligence
distributed software, systems, middleware and frameworks
reflections on the current state and future of ambient intelligence
ambient games and game scenarios
artifacts in ambient intelligence environments (e.g., robots)
deployments and field tests of ambient intelligence technology

All submissions will be peer reviewed. The main proceedings will appear in Springer Lecture Notes in Computer Science (LNCS). Authors are invited to submit their contributions electronically via the conference website: http://www.ami-12.org.

Do users prefer mobile applications or mobile web versions?

Android-ODM-apps-vs-web

When users use their mobile phones to check the news, weather, email, or their social networks, they often have a choice between the mobile web version or a specially-created mobile app. But which do they prefer? Mobile apps – at least according to their time spent.

According to first-reported data from Nielsen Smartphone Analytics, a new effort that tracks and analyzes data from on-device meters installed on thousands of iOS and Android smartphones, the average Android consumer in the U.S. spends 56 minutes per day actively interacting with the web and apps on their phone. Of that time, two-thirds is spent on mobile apps while one-third is spent on the mobile web.

Perhaps more surprising, despite the hundreds of thousands of apps available for Android, a very small proportion of apps make up the vast majority of time spent. In fact, the top 10 Android apps account for 43 percent of all the time spent by Android consumers on mobile apps. The top 50 apps account for 61 percent of all time spent. With 250,000+ Android apps available at the time of this writing, that means the remaining 249,950+ apps have to compete for the remaining 39 percent of the pie.

The question now concerns knowing whether it is more efficient to use a mobile application or a mobile web version. This could aid to justify the correlation between the time spent in interaction and the users' preferences.

Another factor of influence can be the own nature of the tasks performed. It is possible that tasks executed in mobile web versions require more time than mobile applications, affecting thus the interaction time.

Using the available screen space

vivian.motti — Mon, 01 Aug 2011 12:13:05 +0000

8 years ago, Nielsen analyzed the space allocation across 50 website homepages and found that only 40% of screen space was used on navigation

or content of interest to users. This was in the days of 800×600 monitors when space was particularly precious. Today, many websites are a bit better, and bigger monitors obviously allow for more room to play.

Still, sites frequently open important features in tiny pop-ups, violating two guidelines:

Don’t pollute users’ screens with pop-ups.
Show stuff in a space that’s big enough to let users see everything they need to see without scrolling.

Tablets

The proliferation of small, hard-to-use interaction areas in iPad apps is partly Apple’s fault because of a design mistake in the default email application. The inbox is shown as a skinny menu down the side. This is great in the landscape view, letting users quickly alternate between the inbox and individual messages so they can quickly process their mail.

In the portrait orientation, however, the inbox menu appears as an overlay that partly obscures the message content, making it impossible to work with the two panes simultaneously. Why show two panes, when you can’t use both? It would be better to display the inbox across the entire tablet screen, showing more messages and/or more extensive previews of each message.

Bigger is Better

Mobile devices and tablets are inherently small, so you must optimize the use of their screen space and show things as large as possible. Desktop screens are bigger, so you can often achieve a better user experience by enlarging things even more.

There are very few exceptions to the rule that bigger is better in user interfaces. One example is found on sites that insist on opening new windows and maximizing them — even on the biggest of monitors. Once people get a 30-inch monitor, they don’t want maximized browser windows anymore; it’s highly annoying to find, say, a glossary entry taking up 2560×1600 pixels and obscuring the other windows you’re working with.

Optimizing the UI for the available screen space is a key strategy for improving usability.
