Computer Says No: Mobile Apps Connectivity Messages

Sharing some insight into connectivity messages for mobile applications. Based on some recent ethnography done by myself, and prompted by a real business case, I would recommend a message that:


  • In plain language, briefly and directly tells the user what is wrong and why. Something like: Cannot connect because of a network problem.
  • Affords the user a means to retry connecting (or attempts automatically). Mobile context of use means users anticipate possible interruptability and disruption of task, so they will try again as an effective course of action.
  • Tells the user when connection is re-established, and off they go.
  • Saves any work already done, implicitly. (Bonus points on the ADF critical task setting scale for that one.)

The following images showing my experience while reading ADF-EMG Google Groups notification my (Android ICS) Samsung Galaxy S2 during a loss of Wi-Fi give you a good idea of a suitable kind of messaging user experience (UX) for mobile apps in this kind of situation.

The UX possible is dependent on device and platform features, sure, so remember to integrate with the device capability (see point 10 of this great article on mobile design by Brent White and Lynn Rampoldi-Hnilo) but taking these considerations into account is far superior to a context-free dumbed down common error message repurposed from the desktop mentality about the connection to the server being lost, so just "Click OK" or "Contact your sysadmin".

Oracle Applications User Experience Mobile Apps Design Patterns

While in Munich, I also talked about the Oracle Applications User Experience (Applications-UX) Mobile UX strategy.

The Oracle Applications-UX team has made a strategic investment in mobile user experience, with a dedicated team of cognitive psychologists; usability engineers, interaction designers, architects, and so on that innovates fast and hard, brainstorms on cutting edge mobile UX design solutions for all Oracle applications. The mobile space changes rapidly, and this presentation generated a lot of excitement and energy in the audience.

Again, I used local examples to get the message across. I used the Android version of the clever-tanken.de app as a local market example (on the day the top paid Android app in Germany) and illustrated how important ethnography is to the user-centered design process behind our mobile strategy.


Finding that cheap gas in Germany with the clever-tanken.de Android app.

For example, although almost 90% of German workers are contactable out of hours, workers don’t always want to be reached and value their work-lfe balance. VW has agreed not to contact workers in six plants in Germany on their BlackBerries out of hours accordingly. So, from a user requirements perspective in Germany it’s critical to take into account those labor unions or Betriebsräten as stakeholders.

I also explained our user-centered, multistakeholder, mobile design patterns creation process (it includes Apple consultation in the case of iPhone app designs), and how these patterns provide proven cutting edge user experience solutions in a scalable, reusable way for mobile app development teams.

Developing apps using these up-to-the-minute olutions requires a development environment to match. The ever-changing mobile O/S landscape, ADF Mobile enables developers and partners to respond rapidly to changing user experience expectations without redeveloping content. We can support the same content, easily, across different devices with no compromise on user experience or native O/S navigation or actions, while addressing mobile data security issues that customers tell us about, and more. Read the Oracle ADF Mobile white paper for more details.

If you’re presenting to worldwide audiences about mobile user experience, then I recommend that you check out appannie.com for the latest market intelligence including local app popularity charts (it's iPhone, iPad and Android right now) and some very nice infographics on the state of mobile computing. Other useful stats on mobile usage growth, including number of devices and data usage, is available from techcrunch.com.
