How to ’screen read’ a locked PDF

By Rhodri Buttrick on 13 December 2010

Regular readers of my blog will know I have a lot of difficulty with sustained reading.  I can read a few pages okay, or more if the subject matter is quite light.  However, I am studying Philosophy at university and the subject matter is seldom light. The effort it takes for me to read is often so great I have little brain capacity left for actually understanding the material.  This is the case for many dyslexic people and the programme on Kara Tointon (see my earlier blog) illustrated this well. Kara’s brain was scanned and monitored as she read words. Later analysis showed that, whilst she used the same areas of the brain to read, the effort she had to use to decode the words was significantly greater than that for the “normal” population.

new-picture-23Fortunately for me, many of the key texts are provided electronically. I can therefore use a text reader and gain an understanding of the text far more easily by listening to it. My brain does not have to waste valuable capacity on decoding.  I was struggling with some research for an essay and so decided to “read” around the subject and came across a 6 page article which looked as if it might help. Unfortunately this pdf was “locked”. The screen reader could not access it. Help!

After a short panic I thought that perhaps I could print it out and then scan the printed pages and convert them to text.  It would work, even if it was a bit of an effort. However, the solution was better than that. ClaroRead, one of the commonly used assistive programs for dyslexics, is able to “scan” directly from a pdf.  In a matter of seconds, I have a version of the article in a format which Claro’s screen reader could access.
Result!

I’d better get on with that essay now.

Augmented reality games and mobiles

By Alistair Gray on 10 December 2010

My attention has recently been drawn to this video of an entertaining looking augmented reality video game, using a mobile phone, a ‘game board’ and some ‘Skittles’ (other candies are available). For those wondering augmented reality is the addition of computer generated imagery over a real world view to give you an ‘augmented’ view of the world.

The game controls look like a lot of fun, even if the gameplay itself isn’t very deep.

Some interesting quotes from the video:

This isn’t a game to be played sitting down - It’s meant to be dynamic

With motion controls soon to be out on the 3 major consoles, it’s clear that getting game players off the couch is a big aim over Christmas and beyond. This is a great alternative to shelling out a large sum of money for a console. Who needs top of the range motion tracking when you can wave a camera around? With the growth in popularity of smartphones developers have a huge potential market to develop augmented reality games for.

Camera controls that would typically require a mouse and keyboard are handled by simply moving the device … It’s a new experience, that our users have picked up quickly

Controlling the camera is often a real issue for non-game players. This game gets over this problem by simply using a 1-to-1 mapping of the camera with the phone, removing a big barrier to many potential players. Will augmented reality get more people gaming?

Augmented reality has started to appear already. Various apps can, for example show you the nearest tube. But I’m looking for enjoyment, for fun.

I’m really looking forward to augmented reality board games. In fact, more have started to appear on YouTube, maybe they’ll appear quicker than I thought. There’s also potential building much deeper, interactive games directly into the real world (see ‘Conspiracy for Good‘ by Tim King, of Heroes fame).

What do you think? - Will augmented reality take off? Does anyone have any ideas for augmented reality games using a phone?

Communicating UX

By Yeevon Ooi on 10 December 2010

As a UX consultant, I’m constantly trying to communicate information which is abstract and complex on various scales. This could range from specific to conceptual and existent to existence-unknown. Some examples (ranked from less abstract to more abstract) of information that I need to communicate on a daily basis (to clients or colleagues or anyone at all) is shown in the figure below:

Less abstract

  • Discuss colours, font size, typography and how they should be used or look like on a specific interface
  • Describe how a page on a website can be structured, organised, and/or designed
  • Explain interactions on a website or interface
  • Explain project timelines, processes, workflows, and user journeys
  • Describe mental models or subjective experiences held by different people on different topics

More abstract

Some of the above examples can be easily solved by producing wireframes or quick mock-ups, but the tricky ones are explaining mental models, subjective experiences and trying to weave them into a story that you’re trying to tell.

Not surprisingly, a lot of my time at work involves cracking my head to figure out what’s the best way to explain something  so that it makes sense to the person who ’sees’ it, and yes, you guessed it right! Visual artefacts help a lot in communicating these ideas, especially abstract and subjective concepts which shouldn’t be communicated via language alone.

Now the question is what visuals are useful for communicating such ideas? Well, unfortunately there’s no handbook to all the ideas we can possibly present in the world. The good news is there’s no right or wrong way in using visual artefact’s as long as they make sense and explain the message accurately. What works quite well sometimes is using existing diagrams or charts and modifying them to suit what I have to explain.

Telling complicated stories which involve complex processes and abstract concepts don’t usually work well on a screen. Some of the methods which I found useful in the past include using posters full of colour-coded post-it notes, storyboards, sketches, or a bit of all the above methods. In fact, the most effective method involves complementing these different artefact’s (e.g. PowerPoint and handouts of page designs) and weaving them together with the story that you want to tell.

So I say let’s get out of our comfort zone and stop being conscious about our drawing skills or ability to cut and paste things and give this a try the next time a story needs to be told. Oh, and please recycle any materials you produce during this process :)

Increase the clickable area of links using CSS

By Steven Datt on 6 December 2010

This is my first blog post for Webcredible - I’ve just recently joined the team here. My name is Steven Datt; I’ve recently completed a degree at Roehampton in Web & Multimedia computing, and I’m a web developer to the core. I can’t say just how excited I am to have landed this job, not many can say they got their ideal web development job straight out of uni!

I’m mainly a PHP sort of guy, though here at Webcredible I get to learn all sorts of things, from the frontend HTML & CSS to the back end scripting and databases, even the usability testing that goes on. Because of this, I’m in a good position to filter out, interpret and pass on whatever I learn to you, as I learn it - and I’m finding there’s a lot they can teach me here!

Increasing the clickable area for links may seem like a small and insignificant addition, but it actually greatly increases the usability your site offers, which in turn increases potential conversions.

You can see examples of this feature on our site and there’s a way of accomplishing it with a few lines of CSS.

To begin, we’ll create the list items for the navigation:


<ul>
<li><a href='#'>Link 1</a></li>
<li><a href=
'#'>Link 2</a></li>
<li><a href=
'#'>Link 3</a></li>
<li><a href=
'#'>Link 4</a></li>
</ul>

Simple List

Now to add a bit of style to it all:


ul {
list-style: none;
padding: 5px;
margin: 0;
}
ul li {
float: left;
margin: 0 5px;
}
ul li a {
color: #000;
text-decoration: none;
}
ul li a:hover {
background: red;
text-decoration: underline;
}

Which gives us this horizontal aligned navigation bar. Half way there!

icl-step2

So, we’ve created the links, and styled them, the last piece of the puzzle is to put in the CSS to maximise the link area:

ul li a {
color: #000;
text-decoration: none;
}

Add this code which will increase the “hit” area to encompass more space surrounding the link text:

display: block;
padding: 10px;

And we’re done! Told you it was simple!

The user experience of Metropolis

By Philip Webb on 6 December 2010

I recently saw a complete version of the silent era vision of the future, Metropolis. What struck me apart from the prophetic glimpses of video-phones, skyscraper living and robots was the user experience of watching a full-length silent film. Initially, I found it alien and didn’t think my attention span, shortened by Youtube and iTunes, would cope with it.

The lack of speech was intrusive – how could the plot be conveyed without it? The screen titles were sporadic and seemed to repeat the one or two words I’d already managed to lip-read: ‘Maria! Maria!’ The acting and the make-up was over-the-top. Action scenes dragged on some time after I understood what was happening. But then gradually, I started to realise how all these elements were intended.

The screen titles are kept to a minimum to avoid interruptions. The lack of speech is compensated by a glorious film score that becomes integral to the film in a way that soundtracks can’t do now because the music is continuous. Modern film music can sometimes intrude on the experience, signalling too obviously what emotion we’re supposed to feel but in Metropolis the score and the image are coupled so strongly, the feeling of manipulation fades away. Even the hammy acting and the theatrical make-up contribute, becoming a necessary means of expression where the subtleties of dialogue are missing.

The result is a different user experience, one that’s rare now that the blend of music, image, and dialogue has been standardised into a Hollywood norm. But it made me realise that the user experience of films can be varied to good effect by altering the mix of these elements. For example, check out the modern Jeff Mills soundtrack to this classic scene of Maria the ‘man-machine’ coming to life. There’s something chilling and hypnotic about the mix of techno and the 1927 vision of a robot.
