Handheld Devices Functionality Testing – Why It Important

Cellular phone and PDA usability assessment is critical to your business. Actually mobile and handheld functionality testing could possiblybe even more important than computer-based wonderful testing. The main reasons for this are:

— The number of persons accessing the online world from cellular and hand held devices is usually increasing in a massive price – in 2008 upon it’s own there’ll end up being an estimated 54.99 million PDAs sold across the world.

— People generally have way less experience of utilizing their mobile to get 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 by which users gain access to your site is definitely far less expected when using mobile phones. Computer-based prospects generally simply differ from the other person in their browser and operating system (i. y. most people will make use of a screen, mouse and keyboard), whereas the different types of mobile phones and PDAs fluctuate can significantly.

Which will mobile phones and PDAs should you consider?

Cellphones and PDAs can differ from one another noticeably, and this definitely will radically adjust how people experience and use websites. Some of the ways handheld devices can differ consist of:

– Screen-size (small versus large)

– Display screen layout (portrait vs . landscape)

— Input system (stylus, numeric keypad, dial-wheel, QWERTY keypad)

Because the cellular phone / PDA that somebody is applying will have this sort of a outstanding effect on their particular experience of your web site, you should try to try with several mobile phones and PDAs as is feasible.

Of course , examining with every cellphone and PERSONAL DIGITAL ASSISTANT is unachievable. Here are some ideas to help narrow down the number of gadgets you’ll need to check with:

– Your portable site visitors might belong to a specific audience. Particular audiences often prefer particular types of phones (e. g. smartphone with big screens that can support internet access vs . small-screen products that aren’t).
– You will find ‘phone families’ that offer a very similar user experience (and will not likely need to be examined individually).
– You may only want to test along with the most popular mobile phones in Europe as well as most well-known models that are to be used to gain access to your site (you actually can look at your site statistics to find out this information).

Who do you want to test with?

The people you would like to conduct the mobile phone functionality testing visits with will certainly, of course , depend on your particular business and its visitors. Some things tobear in mind include:

— How much knowledge they should currently have of utilizing their mobile phones to locate services. This really is particularly significant as the market meant for accessing on line services through mobile phones is growing and the percent of ‘complete novices’ (i. e. persons using the technology for the first time) will be much higher than designed for computer users of the website.
– Which cellular phone or PDA they have. We might usually recommend that people apply their own mobile phone in a practice session, so the check can give attention to your website rather than on the way the handheld device functions.

Just where should mobile phone usability tests sessions always be conducted?

Mobile phone devices and PDAs are used inside the real world thus usability testing of hand held devices should therefore not merely take place in a usability clinical.

Where, once and how a mobilephone can be used is critical into a person’s experience of the site they can be accessing. Any of the following circumstances could affect this experience and therefore concerns of the web site’s usability:

– Lighting
– Background noises
– Disruptions
– 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 user friendliness testing is definitely conducted at a laboratory and also in the ‘outside world’.

How you schedule and work mobile phone simplicity sessions depends on your organization and its crowd, but the the majority of popular strategies of mobile simplicity testing consist of:

– Lab-based (using a camera to record the session)
– Diary-studies (asking people to continue to keep a diary of how they have used the mobile phone and any concerns they encounter)
– Paper prototypes (running usability screening on a paper based version of your site, applying mobile phone screen-sized pieces of paper)
