Mobile & Handheld Usability Testing — Why This Matters

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

— The number of people accessing the online world from portable and hand held devices is certainly increasing at a massive amount – in 2008 by themselves there’ll be an estimated fifty eight million PDAs sold all over the world.

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

— The platform through which users get your site can be far less foreseen when using mobile phones. Computer-based prospects generally simply differ from the other in their browser and operating-system (i. electronic. most people will make use of a screen, mouse and keyboard), whereas the different types of mobile phones and PDAs vary can drastically.

Which will mobile phones and PDAs must you consider?

Mobile phones and PDAs can differ derived from one of another significantly, and this might radically alter how persons experience and use websites. Some of the ways that handheld units can differ contain:

– Screen size (small vs . large)

– Display screen layout (portrait vs . landscape)

— Input product (stylus, dagplejenjyttejueljensen.dk numeric pad, dial-wheel, QWERTY keypad)

Because the mobile phone / PDA that someone is applying will have this sort of a powerful effect on their particular experience of your web site, you should try to try with as much mobile phones and PDAs as possible.

Of course , screening with every cellphone and PDA is unachievable. Here are some guidelines to help reduce the number of products you’ll need to evaluation with:

— Your cellular site visitors may possibly belong to a certain audience. Selected audiences typically prefer particular types of phones (e. g. phone with big screens that can support on-line access vs . small-screen designs that aren’t).
– You will find ‘phone families’ that offer a very similar user encounter (and will never need to be tested individually).
– You may only want to test with the most well-liked mobile phones in Europe or the most popular models that are to be used to get your site (you can check your site statistics to find out this information).

Who do you wish to test with?

The people you want to conduct the mobile phone usability testing lessons with will certainly, of course , rely upon your particular business and its target market. Some things to make note of include:

— How much experience they should experience of employing their mobile phones to view services. That is particularly important as the market pertaining to accessing web based services through mobile phones keeps growing and the percent of ‘complete novices’ (i. e. persons using the technology for the first time) will be much higher than with regards to computer users of the website.
— Which mobile phone or PDA they have. We would usually suggest that people use their own cellphone in a practice session, so the check can concentrate on your website but not on the way the handheld device works.

Where should cell usability diagnostic tests sessions become conducted?

Cellphones and PDAs are used in the real world therefore usability testing of hand held devices will need to therefore not simply take place in a usability laboratory.

Where, when ever and how a mobile phone is needed is critical into a person’s experience of the site they can be accessing. One of the following conditions could effect this knowledge and therefore concerns of the web site’s usability:

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

As such, there was recommend, if you can, that any mobile phone and PDA wonderful testing is definitely conducted at a clinical and also in the ‘outside world’.

How you program and operate mobile phone wonderful sessions depends on your organization and its target market, but the many popular strategies of mobile user friendliness testing incorporate:

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