User Experience

Number of Internet Users

In 2011, Cisco Internet Business Solutions Group (IBSG) released a report stating that there were 12.5 Billion devices connected to the internet in 2010, exceeding the world population (6.8 Billion) for the first time. Cisco also forecasted that “there will be 25 billion devices connected to the Internet by 2015 and 50 billion by 2020″ [1].

News outlets sensationalized this, taking the finding out of context. Even Cisco’s drew the wild conclusion, “we know that approximately 2 billion people use the Internet today. Using this figure, the number of connected devices per person jumps to 6.25 in 2010, instead of 1.84″ [1].

These claims are fallacies of misplaced correctness, and just ridiculous so lets put it into context.

Before analyzing it logically, lets analyze it anecdotally, using common sense. I’m a technologically savvy individual and I have 1 Desktop + 1 Laptop + 1 SmartPhone + 1 Tablet + 1 Work Computer = 5 Internet Connected Devices. I know that I have more devices than most, so there is no way that the average person had 6.25 Internet-connected devices in 2010.  And, if the percentage of the population to use the Internet grows to 100% in 2015 (best-case), that would mean that the average person has 3.47 devices [1][2].  I really can’t picture the average person in a 3rd world country having as many as 3-4 Internet-connected devices by 2015.

Now lets investigate the cause of this fallacy.  This finding describes the number of devices connected to the internet not the number of people.  Both Cisco and the media are guilty of drawing conclusions from this data without considering the context, and are dead wrong in their predictions.  They are taking “devices” to exclusively mean “personal devices” when really it encompasses:

  • Personal Computers,
  • Work Computers,
  • SmartPhones,
  • Tablets,
  • iPods, and notably,
  • Computer Servers

Google Inc., among other companies, has a larger server farm which contributes to the number of Internet connected devices.  There are so many “devices” in the world that are not “personal devices” that conclusions cannot simply be drawn through dividing the number of “devices” by the world population.

I’m surprised by the lack of critical thinking on behalf of Cisco; they are supposed to be trend setters and reliable guides of the Internet of Things and this has made me seriously doubt their credibility.

If you plan to build a business-model on these future predictions, think critically, and think twice.

How To User Experience

Rainbow Banding : How to analyze results from Usability Testing

I have noticed that there is a wealth of literature online on how to conduct a Usability Study, but I have yet to find anything to demonstrate how to analyze the data collected from a study. Therefore, I thought I’d share a technique that works well for me.  I call it “Rainbow Banding”.

1. Prepare your testing protocol with spaces for participant feedback

Create a protocol template with numbered tasks and questions.  Ensure there is adequate space between each to record relevant answers and observations.


2. Record  the observations

Record the observations from each participant in a fresh copy of this document.  If changes to the protocol, ordering, or wording need to be made, ensure you make them as early in the testing process as possible.

3. Combine your observations

Once you have recorded observations from all of your participants, combine your results in a blank copy of your testing protocol.

Create a section above labelled “Participants” and assign each participant both a unique number and colour. Start by recording the observations from each participant under the appropriate numbered heading (shown below). Use the colour associated with that participant to record the observation. If a second  participant demonstrates the same behaviour or expresses the same sentiment, add a +1 to that observation in the second participant’s colour (this will make analysis easier later-on).

Once you have combined the results from 3 participants, review this list of combined observations and add subheadings to further combine and categorize the findings and observations.  Do this every few participants to make it easier to tally and analyze the results later-on.

In the example above both ‘Dave’ and ‘Holly’ demonstrated the same sentiment under 2) subheading Recent Posts.  +1 was added to the sentiment in each participant’s colour.  You will notice that this helps reduce visual clutter and makes analysis easier at the end.  You will also notice that the subheadings Readability  and  Navigation were added below 4).  Categorizing the feedback as you go along helps chunk the data and will make analysis easier at the end.

4) Tally the Results

Once you have combined the observations from all participants, you can now easily analyze the results adding up similar sentiments, and categorizing findings into a report.

 

Please write me and let me know if this technique worked for you, if you have a similar technique, or if you found it worked poorly.

User Experience Food for Thought with RIM’s Joey Benedek

Tonight I attended a talk by RIM’s Director of UX Research, Joey Benedek, at uxWaterloo.

Joey joined Research in Motion as Director if UX Research in the summer of 2009, just in time to kick off the Blackberry6 development effort. Prior to RIM, Joey spent 9 years at Microsoft spending most of his time in the User Experience organization for Windows finishing his career there as the UX Research manager for Windows 7. Originally from Canada, RIM has provided a homecoming for Joey who completed his graduate work at Carleton’s HCI lab.” -Mark Connolly

Joey Benedek had many interesting things to say, but I thought I’d reiterate some of the more interesting things for myself as well as my loyal reader (also myself).

Facets of Design

There are many facets to the design of a product, as both Joey Benedek and RIM realize:

  • User research
  • Interaction Design
  • Visual / Auditory Design
  • Industrial / ergonomic Design
  • Branding

User research involves requirements gathering- what does the user need and how should their needs be addressed?  Interaction design focuses on creating a meaningful interaction between the interface and the user; again this involves user research.  Visual and auditory design partially cover candy UI, but also creating features that are pleasing and not annoying with repetition.  Industrial and ergonomic design focus on the form factor.  And finally, branding focuses on keeping that recognizable feel.  It’s all a lot to juggle when designing a product, and being equally vital in the design process, it is important that all of these design elements harmonize.

Menus – Efficiency vs. Aesthetics
  • In his experience, text-based one-dimensional menus provide users with far more efficient use.  However, in my experience, this is only when users become proficient and memorize where menu elements are.  There is still a lot of overhead in processing all that text to begin with.
  • In his experience, image-based multi-dimensional menus provide a better experience, but slow user efficiency

One solution to this problem is to used text-based menus with associated icons.  However, as Joey states, it is important not have the iconography overpower the text and distract the user.

Settings – Series vs. Parallel
  • In series, or in sequential flow, is the way that settings have typically been done in the past.  Looking at any Windows version up to Vista you will notice that the computer settings are accessed through a very long list.  Again, someone can become proficient at navigating this list over time, but for the majority of users who access settings infrequently this creates a lot of overhead.  Another example on Windows and the Blackberry is wizards- wizards force the user to modify their settings one step at a time.  There is no flexibility of control.  Often users will get fed up and exit the wizard without setting anything pertinent up.
  • In parallel, users have the option of setting up whatever they want, in what order they want, by selecting an according action.  For example, “Set up-email” or “Change Display Preferences.”  The best way categorize these settings is to do card sorting with users, getting them to label categories as verbs.
Don’t break design patterns
  • If users have become accustomed to using your product in a certain way, and they enjoy it, don’t change it on them next revision.  This poses a new challenge for designers: How do we create the next iteration of design without breaking the thing that users are used to, enjoy, and identify with us.
Personas vs. Scenarios
  • Knowing your target user is important, but the goal of developing personas is not  to directly use this information to evaluate the product, rather to understand the contexts of use.  Once you have developed your contexts of use (scenarios), use those to design and evaluate the product.
