Mobile & Handheld Functionality Testing – Why It Important

Cellphone and PDA usability evaluating is critical to your business. Actually mobile and handheld functionality testing could possibly be even more important than computer-based simplicity testing. The primary reasons for this kind of are:

— The number of persons accessing the Internet from cell and portable devices is increasing in a massive level – in 2008 exclusively there’ll be an estimated 49.50 million PDAs sold all over the world.

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

— The platform by which users gain access to your site is certainly far less expected when using cellphones. Computer-based website visitors generally only differ from the other person in their web browser and os (i. age. most people will make use of a screen, mouse button and keyboard), whereas the several types of mobile phones and PDAs fluctuate can significantly.

Which in turn mobile phones and PDAs must you consider?

Cellphones and PDAs can differ from a single another substantially, and this is going to radically transformation how persons experience and use websites. Some of the ways in which handheld units can differ involve:

– Screen size (small versus large)

– Screen layout (portrait vs . landscape)

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

Because the mobile phone / PERSONAL DIGITAL ASSISTANT that an individual is using will have this sort of a serious effect on the experience of your site, you should try to evaluate with numerous mobile phones and PDAs as is feasible.

Of course , tests with every mobile phone and PDA is very unlikely. Here are some ideas to help reduce the number of products you’ll need to test out with:

– Your mobile phone site visitors may possibly belong to a selected audience. Certain audiences are more likely to prefer particular types of phones (e. g. phones with big screens that are designed to support via the internet access versus small-screen units that aren’t).
– You will discover ‘phone families’ that offer a very similar user experience (and is not going to need to be analyzed individually).
– You may only want to test considering the most well-known mobile phones in Europe or perhaps the most well-liked models that are being used to access your site (you can look at your site stats to find out this kind of information).

Who do you want to test with?

The people you need to conduct the mobile phone functionality testing trainings with might, of course , depend on your particular organization and its audience. Some things to keep in mind include:

– How much experience they should possess of utilizing their mobile phones to gain access to services. This can be particularly crucial as the market for the purpose of accessing over the internet 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 with respect to computer users of the website.
– Which cellphone or PDA they have. We might usually recommend that people make use of their own cellular phone in a workout, so the check can focus on your website not on the way the handheld device works.

Wherever should cell usability testing sessions be conducted?

Mobile phone devices and PDAs are used inside the real world and so usability testing of portable devices will need to therefore not merely take place in a usability laboratory.

Where, when and how a mobile phone is needed is critical to a person’s experience of the site they are simply accessing. Many of the following instances could effect this knowledge and therefore considerations of the website’s usability:

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

As such, we’d recommend, if you can, that virtually any mobile phone and PDA usability testing is conducted in a lab and also in the ‘outside world’.

How you approach and work mobile phone functionality sessions will be based on your business and its visitors, but the many popular strategies to mobile simplicity testing contain:

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