Mobile & Handheld Functionality Testing — Why This Matters

Mobile phone and PDA usability screening is critical to your business. Actually mobile and handheld usability 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 net from mobile phone and hand held devices is certainly increasing at a massive rate – in 2008 together there’ll become an estimated fifty eight million PDAs sold all over the world.

— People generally have a lot less experience of using their mobile to go online than they do of using their laptop. This means that computer-based users may be assumed to have a higher level of existing expertise than mobile and handheld users.

— The platform through which users get your site is normally far less foreseen when using mobiles. Computer-based readers generally simply differ from the other in their internet browser and os (i. at the. most people will make use of a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs change can substantially.

Which will mobile phones and PDAs must you consider?

Mobile phones and PDAs can differ from one another significantly, and this will certainly radically adjust how persons experience and use websites. Some of the ways handheld equipment can differ contain:

– Screen size (small or large)

– Screen layout (portrait vs . landscape)

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

Because the cellphone / PDA that somebody is employing will have these kinds of a outstanding effect on their particular experience of your web blog, you should try to evaluate with as much mobile phones and PDAs as it can be.

Of course , assessment with every mobile phone and PDA is impossible. Here are some suggestions to help focus the number of gadgets you’ll need to evaluation with:

– Your mobile phone site visitors may possibly belong to a particular audience. A number of audiences are inclined to prefer particular types of phones (e. g. handsets with big screens that are designed to support on the net access versus small-screen styles that aren’t).
– You will discover ‘phone families’ that offer the same user encounter (and is not going to need to be examined individually).
– You may only want to test considering the most well-liked mobile phones in Europe or the most well-known models that are to be used to gain access to your site (you can look at your site statistics to find out this kind of information).

Who do you want to test with?

The people you want to conduct your mobile phone user friendliness testing instruction with will, of course , rely upon your particular business and its target audience. Some things to make note of include:

— How much experience they should have got of utilizing their mobile phones to locate services. This can be particularly important as the market meant for accessing internet services through mobile phones keeps growing and the percent of ‘complete novices’ (i. e. people using the technology for the first time) will be a long way higher than with regards to computer users of your website.
— Which cellular phone or PDA they have. We might usually recommend that people employ their own mobile phone in a time, so the evaluation can focus on your website but not on the way the hand-held device performs.

Exactly where should portable usability assessment sessions become conducted?

Cellphones and PDAs are used in the real world so usability examining of portable devices ought to therefore not merely take place in a usability clinical.

Where, when and how a mobile phone can be used is critical to a person’s experience of the site they are accessing. Many of the following circumstances could influence this experience and therefore considerations of the web site’s usability:

– Lighting
– Background sound
– Interruptions
– Contingency tasks (i. e. whatever the person is performing at the same time)
– Physical movement

As such, there was recommend, if at all possible, that virtually any mobile phone and PDA user friendliness testing can be conducted in a laboratory and also in the ‘outside world’.

How you program and work mobile phone wonderful sessions depends on your organization and its viewers, but the the majority of popular strategies of mobile usability testing include:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to retain a diary of how they have used all their mobile phone and any problems they encounter)
– Newspaper prototypes (running usability screening on a paper-based version within the site, using mobile phone screen-sized pieces of paper)
