Mobile & Handheld Functionality Testing — Why That Matters

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

– The number of people accessing the world wide web from cell and handheld devices can be increasing by a massive pace – in 2008 exclusively there’ll end up being an estimated 49.50 million PDAs sold across the world.

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

— The platform whereby users gain access to your site is normally far less foreseeable when using mobiles. Computer-based readers generally simply differ from the other person in their web browser and operating system (i. y. most people will use a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs fluctuate can considerably.

Which mobile phones and PDAs do you need to consider?

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

– Screen size (small versus large)

– Display layout (portrait vs . landscape)

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

Because the cellphone / PERSONAL DIGITAL ASSISTANT that someone is applying will have these kinds of a powerful effect on all their experience of your web site, you should try to check with several mobile phones and PDAs as is feasible.

Of course , examining with every mobile phone and PDA is out of the question. Here are some ways to help reduce the number of units you’ll need to evaluation with:

— Your mobile site visitors may belong to a specific audience. Specified audiences often prefer particular types of phones (e. g. cell phones with big screens that can support web based access versus small-screen types that aren’t).
– There are ‘phone families’ that offer a very similar user experience (and will not likely need to be examined individually).
— You may only want to test considering the most popular mobile phones in Europe as well as most well-known models that are being used to access your site (you actually can check your site figures to find out this information).

Who do you wish to test with?

The people you need to conduct the mobile phone simplicity testing sessions with can, of course , be based upon your particular business and its visitors. Some things to bear in mind include:

— How much experience they should have of using their mobile phones to view services. This really is particularly crucial as the market just for accessing over the internet services through mobile phones is growing and the percent of ‘complete novices’ (i. e. people using the technology for the first time) will be very good higher than just for computer users of your website.
— Which cellular phone or PDA they have. We might usually suggest that people make use of their own cellphone in a program, so the check can give attention to your website and not on the way the hand-held device works.

Exactly where should mobile phone usability evaluating sessions end up being conducted?

Mobile phones and PDAs are used in the real world therefore usability examining of hand held devices ought to therefore not simply take place in a usability lab.

Where, the moment and how a mobile phone is employed is critical to a person’s connection with the site they are simply accessing. Any of the following situations could effect this encounter and therefore things to consider of the site’s usability:

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

As such, there was recommend, if at all possible, that virtually any mobile phone and PDA functionality testing is certainly conducted both in a laboratory and also in the ‘outside world’.

How you system and run mobile phone wonderful sessions depends on your organization and its readership, but the the majority of popular ways of mobile user friendliness testing involve:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to hold a diary of how they have used their particular mobile phone and any concerns they encounter)
– Newspapers prototypes (running usability diagnostic tests on a paper based version with the site, applying mobile phone screen-sized pieces of paper)
