Mobile & Handheld Functionality Testing — Why It Matters

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

— The number of people accessing the world wide web from mobile phone and handheld devices is definitely increasing for a massive pace – in 2008 by themselves there’ll be an estimated 58 million PDAs sold around the globe.

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

— The platform through which users gain access to your site can be far less estimated when using mobiles. Computer-based prospects generally simply differ from the other in their internet browser and os (i. age. most people will use a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs differ can drastically.

Which in turn mobile phones and PDAs must you consider?

Mobiles and PDAs can differ from a another drastically, and this should radically transformation how people experience and use websites. Some of the ways in which handheld devices can differ consist of:

– Screen-size (small vs . large)

– Screen layout (portrait vs . landscape)

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

Because the mobile phone / PDA that someone is using will have these kinds of a powerful effect on their experience of your web sites, you should try to evaluate with numerous mobile phones and PDAs as is feasible.

Of course , assessment with every mobile phone and PDA is not possible. Here are some ideas to help reduce the number of gadgets you’ll need to evaluation with:

– Your mobile site visitors may belong to a specialized audience. A number of audiences typically prefer particular types of phones (e. g. telephones with big screens that will support on the web access or small-screen designs that aren’t).
– You will find ‘phone families’ that offer the same user encounter (and is not going to need to be analyzed individually).
— You may only want to test while using most popular mobile phones in Europe and also the most well-known models that are being used to gain access to your site (you can check your site stats to find out this information).

Who do you want to test with?

The people you want to conduct your mobile phone wonderful testing periods with will, of course , rely upon your particular organization and its readership. Some things to keep in mind include:

– How much knowledge they should contain of utilizing their mobile phones to access services. This is certainly particularly important as the market intended for accessing on the web services through mobile phones is growing and the percent of ‘complete novices’ (i. e. persons using the technology for the first time) will be a lot higher than intended for computer users of your website.
– Which cellphone or PERSONAL DIGITAL ASSISTANT they have. We would usually recommend that people make use of their own mobile phone in a practice session, so the evaluation can give attention to your website and not on the way the handheld device performs.

Where should portable usability evaluating sessions become conducted?

Mobiles and PDAs are used inside the real world thus usability diagnostic tests of handheld devices should certainly therefore not only take place in a usability laboratory.

Where, once and how a mobile phone can be used is critical into a person’s experience of the site they are accessing. Any of the following situations could impact this knowledge and therefore things to consider of the web site’s usability:

— Lighting
– Background noises
– Interruptions
– Contingency tasks (i. e. nearly anything the person has been doing at the same time)
– Physical movement

As such, we would recommend, whenever possible, that virtually any mobile phone and PDA functionality testing is normally conducted in a lab and also inside the ‘outside world’.

How you plan and operate mobile phone user friendliness sessions depends on your organization and its readership, but the the majority of popular strategies of mobile user friendliness testing include:

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