Handheld Devices Simplicity Testing – Why This Matters

Mobile phone and PDA usability testing is critical on your business. Actually mobile and handheld simplicity testing could possibly be even more important than computer-based usability testing. The key reasons for this kind of are:

— The number of persons accessing the world wide web from cellular and hand held devices is certainly increasing at a massive level – in 2008 by themselves there’ll end up being an estimated 49.50 million PDAs sold international.

– People generally have much less experience of using their mobile going online than they do of using their computer. This means that computer-based users can be assumed to possess a higher level of existing expertise than mobile and handheld users.

— The platform by which users access your site is normally far less foreseen when using cell phones. Computer-based readers generally just differ from the other person in their browser and operating system (i. e. most people will use a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs are different can greatly.

Which mobile phones and PDAs must you consider?

Mobiles and PDAs can differ from a another significantly, and this is going to radically improve how people experience and use websites. Some of the ways in which handheld gadgets can differ include:

– Screen-size (small versus large)

– Display layout (portrait vs . landscape)

– Input machine (stylus, numeric keypad, dial-wheel, QWERTY keypad)

Because the cellphone / PERSONAL DIGITAL ASSISTANT that somebody is using will have these kinds of a powerful effect on their very own experience of your internet site, you should try to try with several mobile phones and PDAs as is feasible.

Of course , screening with every cellular phone and PDA is extremely hard. Here are some guidelines to help reduce the number of devices you’ll need to check with:

— Your portable site visitors may well belong to a particular audience. Specific audiences often prefer particular types of phones (e. g. handsets with big screens that can support over the internet access versus small-screen models that aren’t).
– You will discover ‘phone families’ that offer the same user experience (and is not going to need to be examined individually).
– You may only want to test while using the most well-known mobile phones in Europe or maybe the most well-known models that are being used to access your site (you can look at your site figures to find out this kind of information).

Who do you need to test with?

The people you wish to conduct your mobile phone wonderful testing treatments with should, of course , rely upon your particular organization and its customers. Some things to make note of include:

– How much experience they should contain of employing their mobile phones to gain access to services. This is particularly significant as the market to get accessing web based services through mobile phones keeps growing and the percent of ‘complete novices’ (i. e. people using the technology for the first time) will be considerably higher than with regards to computer users of the website.
— Which cellphone or PERSONAL DIGITAL ASSISTANT they have. We would usually advise that people use their own cellphone in a appointment, so the evaluation can give attention to your website certainly not on the way the hand-held device performs.

In which should cellular usability screening sessions become conducted?

Mobile phones and PDAs are used in the real world thus usability tests of hand held devices will need to therefore not simply take place in a usability clinical.

Where, once and how a mobile phone can be used is critical to a person’s connection with the site they are really accessing. Many of the following situations could impact this knowledge and therefore factors of the website’s usability:

— Lighting
– Background noise
– Interruptions
– Contingency tasks (i. e. anything the person is doing at the same time)
– Physical movement

As such, we would recommend, if at all possible, that any mobile phone and PDA usability testing is normally conducted both in a laboratory and also inside the ‘outside world’.

How you package and operate mobile phone simplicity sessions depends on your organization and its visitors, but the many popular techniques of mobile functionality testing consist of:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to retain a record of how they may have used the mobile phone and any problems they encounter)
– Standard paper prototypes (running usability diagnostic tests on a paper based version from the site, employing mobile phone screen-sized pieces of paper)
