Handheld Devices Functionality Testing – Why This Important

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

– The number of persons accessing the world wide web from cellular and hand held devices is normally increasing for a massive rate – in 2008 on your there’ll become an estimated fifty eight million PDAs sold all over the world.

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

— The platform whereby users get your site can be far less foreseeable when using mobile phones. Computer-based guests generally simply differ from the other person in their browser and os (i. e. most people will make use of a screen, mouse button and keyboard), whereas the different types of mobile phones and PDAs change can substantially.

Which in turn mobile phones and PDAs should you consider?

Mobiles and PDAs can differ from a single another significantly, and this will radically alter how persons experience and use websites. Some of the ways in which handheld products can differ consist of:

– Screen-size (small or large)

– Display layout (portrait vs . landscape)

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

Because the cellphone / PDA that somebody is employing will have such a outstanding effect on their experience of your web blog, you should try to evaluate with several mobile phones and PDAs as is feasible.

Of course , tests with every cellphone and PDA is unattainable. Here are some guidelines to help narrow down the number of products you’ll need to test out with:

— Your portable site visitors may well belong to a certain audience. Specified audiences tend to prefer particular types of phones (e. g. phones with big screens that are designed to support online access or small-screen products that aren’t).
– You will discover ‘phone families’ that offer the same user encounter (and will not likely need to be examined individually).
— You may want to00 test while using the most well-liked mobile phones in Europe or perhaps the most popular models that are to be used to get your site (you can look at your site statistics to find out this information).

Who do you wish to test with?

The people you wish to conduct the mobile phone functionality testing visits with can, of course , depend on your particular organization and its market. Some things to make note of include:

— How much knowledge they should have of using their mobile phones to locate services. That is particularly significant as the market with respect to accessing web based services through mobile phones is growing and the percent of ‘complete novices’ (i. e. people using the technology for the first time) will be even higher than with regards to computer users of your website.
– Which cellular phone or PERSONAL DIGITAL ASSISTANT they have. We would usually recommend that people use their own cellphone in a appointment, so the test can focus on your website but not on the way the hand-held device works.

Just where should cellular usability diagnostic tests sessions become conducted?

Cellphones and PDAs are used in the real world and so usability screening of handheld devices should certainly therefore not simply take place in a usability lab.

Where, once and how a mobile phone is used is critical into a person’s experience of the site they are accessing. The following circumstances could effect this encounter and therefore considerations of the web site’s usability:

– Lighting
– Background noises
– 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 simplicity testing is definitely conducted in a clinical and also inside the ‘outside world’.

How you method and manage mobile phone simplicity sessions depends on your organization and its projected audience, but the the majority of popular strategies to mobile usability testing consist of:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to maintain a diary of how they have used their very own mobile phone and any problems they encounter)
– Old fashioned paper prototypes (running usability screening on a paper based version belonging to the site, applying mobile phone screen-sized pieces of paper)
