Mobile & Handheld Functionality Testing – Why It Matters

Cellphone and PDA usability testing is critical to your business. Actually mobile and handheld usability testing could be even more important than computer-based wonderful testing. The key reasons for this are:

– The number of people accessing the online world from mobile phone and portable devices can be increasing at a massive price – in 2008 on your there’ll end up being an estimated fifty eight million PDAs sold across the world.

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

– The platform by which users get your site is definitely far less expected when using mobile phones. Computer-based prospects generally just differ from the other in their web browser and operating system (i. y. most people will make use of a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs vary can substantially.

Which usually mobile phones and PDAs do you need to consider?

Mobile phone devices and PDAs can differ from another noticeably, and this can radically modification how people experience and use websites. Some of the ways handheld devices can differ involve:

– Screen-size (small vs . large)

– Display screen layout (portrait vs . landscape)

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

Because the cellphone / PDA that someone is employing will have such a serious effect on their particular experience of your site, you should try to try with as many mobile phones and PDAs as is possible.

Of course , examining with every cellphone and PERSONAL DIGITAL ASSISTANT is extremely hard. Here are some suggestions to help focus the number of devices you’ll need to test with:

– Your mobile phone site visitors may belong to a specialized audience. Several audiences are likely to prefer particular types of phones (e. g. cellular phones with big screens that are designed to support on theweb access or small-screen products that aren’t).
– You will discover ‘phone families’ that offer a very similar user encounter (and will not likely need to be tested individually).
— You may want to00 test when using the most well-known mobile phones in Europe or perhaps the most well-liked models that are being used to access your site (you actually can look at your site figures to find out this kind of information).

Who do you wish to test with?

The people you need to conduct your mobile phone simplicity testing trainings with will certainly, of course , depend on your particular organization and its readership. Some things to keep in mind include:

— How much encounter they should include of utilizing their mobile phones to view services. This can be particularly crucial as the market with respect to accessing on the net services through mobile phones keeps growing and the percent of ‘complete novices’ (i. e.persons using the technology for the first time) will be a lot higher than with regards to computer users of your website.
— Which cellular phone or PDA they have. We might usually recommend that people work with their own mobile phone in a period, so the test can concentrate on your website and not just on the way the hand-held device functions.

In which should mobile phone usability testing sessions become conducted?

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

Where, once and how a mobile phone can be used is critical to a person’s connection with the site they are accessing. The following situations could influence this knowledge and therefore factors of the website’s usability:

– Lighting
— Background noises
– Interruptions
– Concurrenttasks (i. e. nearly anything the person is doing at the same time)
– Physical movement

As such, we would recommend, when possible, that any mobile phone and PDA wonderful testing is certainly conducted in a laboratory and also in the ‘outside world’.

How you prepare and manage mobile phone user friendliness sessions will be based on your organization and its customers, but the most popular strategies to mobile usability testing involve:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to keep a record of how they may have used the mobile phone and any concerns they encounter)
– Old fashioned paper prototypes (running usability evaluating on a paper-based version on the site, employing mobile phone screen-sized pieces of paper)
