Researching Usability

Interactive Triptych Framework (ITF)

This week has been largely spent reading papers as I try to review the Interactive Triptych Framework as a possible framework for evaluating library@nesc later in the project. I still feel like I’m at the beginning of a long journey on this subject and often find that Twitter can be a massive distraction when trying to concentrate for longer than 20 minutes! That being said, I wanted to summarise the framework below from the paper which proposed it. Other papers of relevance will be documented in subsequent blogs.

Analysing and evaluating usefulness and usability in electronic information services, Tsakonas & Papatheodorou, Journal of Information Science, 2006;32

This paper presents the ITF model and suggests that interaction is effected equally by content and system characteristics. It also states that usefulness and usability are interconnected from the user’s point of view. ITF is a holistic picture of user interaction and other approaches to Electronic Information Services (EIS) evaluation. The proposed framework illustrates the interactions taking place between the three components: system, content and users. Each component interacts with each other and it is these interactions which define three evaluation approaches: usefulness, usability and performance.

An important observation of the research paper was the identification of a correlation between usefulness and usability from the users point of view. In addition to this is that fact that all attributes (usefulness, usability and performance) were equally preferred by users and considered important for their interaction. However, the research also reported that usefulness precedes usability when users are asked to state a preference suggesting that content quality is paramount for EISs.

An integrated approach which evaluates usefulness and usability is recommended in order to provide a holistic image of user interaction. If the ITF were to be adopted for the planned evaluation of library@nesc then such an approach would need to be designed. This is something which I intend to give some thought to.

Social Media event from NESTA

In addition to reading this week I also watched a streamed event on social media organised by NESTA entitled ‘Social media – a force for good?’. This well organised and interesting event invited three people with something to say on the subject to answer questions: Stephen Fry, Biz Stone (founder of Twitter) and Reid Hoffman (founder of LinkedIn). If you missed the live stream you can watch on the NESTA website. Although it was a talk on social media, Twitter inevitably dominated the questions. I’ve summarised a couple of points raised which I thought were topical and of interest:

  • Biz stated that his prediction for Twitter in years to come is that it won’t be triumph of technology, more a triumph of humanity. It seemed like there has been recent debate about social media and whether or not it is a saviour or slayer of humanity. I think scientific research will play a great role in attempting to answer this question. Twitter is relatively young and very little (if any) solid research has been done on its effects on individuals and society. There seems to be a huge amount of potential for researchers on this subject and this makes it an exciting subject.
  • Another similar question asked if things like Twitter are increasing isolation amongst people. Biz refuted this when he pointed to the many Tweetups that happen around the world. As an attendee of a weekly Twitter related meet-up- Edinburgh Coffee Morning I tend to agree. Although I am relatively new to the group it seems that many friendships have been formed through face-to-face conversation which has continued on into Twitter and more recently Facebook. The Guardian wrote this week  ‘Is local the new social now?’ and when thinking about the popularity and regularity of local Tweetups then it is fair to say that it is.
  • Finally a topic which cropped up a few times was the power of the masses on Twitter. Reid Hoffman put it as “The wisdom of the crowd or the madness of the masses.” This refers not only to the information which influences us on an individual basis but also the potential of Twitter (and all forms of mass communication) to whip people up into a frenzy with (possible) catastrophic consequences. One could argue that the masses are not on Twitter which is equally correct but I wonder how long it will be before this changes and we see more extremists using Twitter to communicate their message (if not already)? Something to be aware of at least.

Finally

I thought I would post another Dilbert strip which I saw this week. Its on the theme of cloud computing and made me laugh. Have a great weekend!

So I’ve been meaning to create my own blog for a while. After joining the UX2.0 project last week its finally materialised. Although there will be an official UX2.0 blog on the website (still under construction), I wanted to get started on my own blog so I can talk about the project more informally. I’m hoping that it will not only serve to keep others updated  but also invite some discussion and input into the project as we begin to collect results.

It will hopefully also be a space where I can also talk about usability in general, from current research methods to my own experiences. If you are visiting my blog for the first time, thanks for stopping by. It may be a bit light on the ground at the moment but please check back here again soon or better still save it to your RSS feed to be kept right up to date! 🙂

Since its Friday and the weekend is imminent, I though I would share one of the many great Dilbert comic strips on usability, enjoy!
