Facebook considered easiest to use social network - I’m dubious

By Trenton Moss on 12 March 2010

Is it? Really? Personally I’m doubtful, but that’s the conclusion of our recent social network usability poll in which half of the respondents felt that Facebook was the easiest to use social network. We asked people ‘which social networking site do you think is the easiest to use?’ The full results were:

  • Myspace – 4%
  • Facebook – 50%
  • Twitter – 19%
  • Bebo – 1%
  • Friends Reunited – 1%
  • LinkedIn – 5%
  • Other – 7%
  • None of them are easy to use – 12%

Looking at those results, there’s clearly a correlation between the voting and the popularity of the social networks in question - no surprise really because the more you use a website the easier you will find it to use.

The difference between social networks and other websites is that the sites themselves are a pass-time, so users can (and are often happy to) learn how to use them properly. On other sites they usually wouldn’t be prepared to take the time.

I think the results might be very different if you were to have a sample of people that had never used any of these sites before, and you carried out usability testing on all the sites. Given the simplicity of Twitter’s proposition, I would expect that it’s the easiest to use for a beginner as there’s far less to learn compared to say Facebook or  any other social network.

I’d be interested to hear what you make of these results…

Guest blog - Computers find male voices ‘harder to recognise’ - Oh dear

By Rhodri Buttrick on 9 March 2010

On 4 March, I came across an article on the BBC News web site reporting that some researchers at Stamford University and at Edinburgh University found, Computers find male voices ‘harder to recognise’. Now I am male and as I cannot hand write, I have been using voice recognition technology (VRT) since I was 10 years old. So, I “screen read” the article to see what insights it had for me.

When I started using VRT, I could barely read but had to read “training text” for the computer to learn my voice. My mother had to sit behind me, whispering the text into my ear in short phrases, which I repeated into the microphone. I was using Dragon Naturally Speaking version 5. It was hard work, but I persevered as this was the last chance saloon for me as I was unable to write and typing was painfully (literally!) slow. I adopted the “good practices” recommended by the software supplier, such as correcting any recognition errors as I went along using the “Correct That” function, rather than overtyping. The result was I achieved a recognition level of over 98%, talking in a natural way, at normal talking speed.

So, what about the Edinburgh and Stamford Universities’ research?  The BBC report says:

Computers failed to understand men’s speech because they make “umm” and “err” sounds more frequently.

Comment: I could have told them this ten years ago! Of course sloppy speech makes recognition levels bad and perhaps men umm and err more than women! People with speech ticks such as saying “y’know” in every sentence also have problems. Isn’t there and old computing saying of “trash in, trash out”?

Computers made mistakes with words which sound similar and can occur in similar contexts, such as “I saw him” or “I saw them”.

Comment: This is a good point. They ought to try “I scream” and “ice cream”. In one of my Religious Studies essays I had “cheeses of Nazareth” leading his disciples. I have however got round this now and I’ll tell you how in a later blog.

Variations in pitch, tone and speed can also cause the system to misunderstand voices.

Comment: Not for me; even though my voice broke, my good practices carried me through and I can talk as fast I want to.

It then said the research was to “improve the accuracy of automated ticket booking lines.” Ah!!! This research was not for people like me after all. It was all about replacing call centre staff with machines; this software would have to deal with any voice without the benefit of any training! Perhaps, if they crack this problem, it will eventually benefit people who cannot hand write or maybe it will be so expensive, it will remain the preserve of the major corporates.

Only the future will tell; until then, I’ll keep using my Dragon Naturally Speaking software coupled with some common sense good practices.

Are your PDFs accessible?

By Brigitte Simard on 3 March 2010

We often get asked about by clients, so I thought I’d also share some thoughts on this matter in this blog post.

Accessible PDFs

PDF files have always been embedded in web pages and that’s not likely to change in the near future. The real challenge here is making sure that the information in the PDF can be accessed by all users, as screen reader and screen magnifier users have traditionally had problems with PDFs. However, screen readers can now read aloud PDF files and they can be magnified by screen magnifiers.

Creating a new PDF

Firstly, you’ll need to make your Word document accessible through the following steps:

To create the PDF you then need to select the toolbar icon:

The alternative way of creating PDFs, that is, printing to Adobe PDF should not be used. This latter method does not tag the PDF document, meaning that all heading information is lost.

After the PDF has been created, you must then check that the document is properly tagged and bookmarked.

Converting existing PDFs

With Acrobat Writer, it’s possible to modify an existing PDF through the following steps:

  • Add new tag
  • View, Re-order, Rename, Modify, Delete or Create tags
  • Update the reading order
  • Add alternative  text to images
  • Convert a scanned PDF with Optical Character Recognition (OCR)

We will follow this post up with a more substantial article in the next couple of months, but let us know in the meantime what your thoughts are on the accessibility of PDFs.

Guest blog - Student loans, another online form!

By Rhodri Buttrick on 2 March 2010

An email came into my inbox and I stared at it with trepidation. It was a reminder to apply for my student loan for my second year at university. I remembered last year: it took ages; I couldn’t find the information and then it timed out as I was too slow.  Next I thought, where did I put the record of last year’s application? What did I say? What if I am not consistent? Is any of the information here (at Uni) or is it at home?  I put it off applying as long as I could but felt that if I didn’t tackle it soon, I wouldn’t get a loan. So, I set aside a whole afternoon and logged in. But, what was this I saw? All last year’s data was already entered! All I had to do was go through each page confirming that is was correct: place of study, course, course code, address (term time) and so on. The only additional data I needed had been sent to me by the university in plenty of time – that was the annual course fee.

After half an hour, the whole application was done. The only tricky part was when the form had an ambiguous question on “Did I want to apply for disability allowance?”  Contrary to my instincts, the right answer was “No” as I had already applied the previous year and disability allowance is for the full 3 years and doesn’t have to be reapplied for.  So, 9 out 10 for the people who designed that form, making it easier for people like me and, as a wider benefit, easier for everyone else as well.

What’s happening at Webcredible

As March rolls around I seem to be spending much of my time sifting through CVs and doing interviews - we’re currently recruiting for both a new marketing manager and head of UX and have had a huge response for both roles. The economic downturn becomes really apparent when we recruit as we end up getting so many responses from some incredibly qualified candidates. We’ve also recently taken on a couple of great new UX consultants so lots of new faces around the office.

Other than recruiting, we’re as busy as usual doing the usual range of usability, accessibility and design projects, as well as lots of training courses. We’ve also got a new advanced web writing training course starting later this month, so are just putting the finishing touches to this. This follows on from the launch of our other 2 new courses, SEO & PPC training this month.

We additionally published our annual ecommerce accessibility report, which as usual picked up plenty of press coverage and got lots of Twitter mentions. This year B&Q topped the charts with a record-high 84% - very impressive and well done to the web team over there. Every year we evaluate the website accessibility of 20 of the major UK high street retailers. Although there were some good improvements from the likes of B&Q,  the overall average slipped slightly which isn’t so encouraging.

Finally we got out and about a bit this month, with our marketing manager Jon presenting at the National Housing Federation Marketing Communications conference on how to engage audiences through social media (watch the video on our YouTube channel). I also presented at an SME ecommerce event at Wembley Stadium on how to increase conversion rates. I have to say, presenting with a view of the entire stadium is certainly impressive. The view - along with the fact that I was presenting with a microphone in my hand - made me rather tempted to break out into song as any rock star wouldn’t. Fortunately for the audience I didn’t.
