Mobile & Handheld Usability Testing – Why It Matters

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

— The number of persons accessing the web from mobile phone and portable devices is usually increasing in a massive rate – in 2008 alone there’ll always be an estimated fifty eight million PDAs sold across the world.

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

– The platform by which users get your site can be far less expected when using mobiles. Computer-based website visitors generally just differ from one another in their browser and operating-system (i. age. most people will use a screen, mouse and keyboard), whereas the several types of mobile phones and PDAs are different can dramatically.

Which in turn mobile phones and PDAs must you consider?

Mobiles and PDAs can differ from one another noticeably, and this can radically alter how people experience and use websites. Some of the ways handheld products can differ contain:

– Screen size (small or large)

– Display layout (portrait vs . landscape)

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

Because the cellular phone / PERSONAL DIGITAL ASSISTANT that somebody is employing will have this sort of a unique effect on their experience of your websites, you should try to check with several mobile phones and PDAs as possible.

Of course , examining with every mobile phone and PERSONAL DIGITAL ASSISTANT is unachievable. Here are some ideas to help focus the number of gadgets you’ll need to test out with:

— Your portable site visitors could belong to a selected audience. Specific audiences are more likely to prefer particular types of phones (e. g. cell phones with big screens that will support internet access or small-screen versions that aren’t).
– You will discover ‘phone families’ that offer the same user encounter (and will never need to be examined individually).
— You may want to00 test with the most well-liked mobile phones in Europe as well as most popular models that are to be used to get your site (you actually can look at your site figures to find out this kind of information).

Who do you need to test with?

The people you need to conduct the mobile phone user friendliness testing times with is going to, of course , rely upon your particular organization and its target audience. Some things to bear in mind include:

— How much knowledge they should include of utilizing their mobile phones to gain access to services. That is particularly important as the market meant for accessing on the web 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 designed for computer users of your website.
– Which cellphone or PERSONAL DIGITAL ASSISTANT they have. We would usually advise that people work with their own mobile phone in a program, so the check can concentrate on your website and never on the way the handheld device works.

Wherever should cell usability screening sessions be conducted?

Mobile phone devices and PDAs are used inside the real world consequently usability evaluating of hand held devices should therefore not simply take place in a usability lab.

Where, the moment and how a mobile phone is needed is critical to a person’s connection with the site they may be accessing. The following situations could influence this experience and therefore things to consider of the website’s usability:

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

As such, we would recommend, if at all possible, that virtually any mobile phone and PDA usability testing is definitely conducted at a lab and also in the ‘outside world’.

How you system and work mobile phone user friendliness sessions depends on your organization and its audience, 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 diary of how they have used their very own mobile phone and any challenges they encounter)
– Newspapers prototypes (running usability screening on a paper based version from the site, using mobile phone screen-sized pieces of paper)
