Handheld Devices Wonderful Testing – Why It Matters


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

– The number of people accessing the world wide web from cellular and hand held devices is definitely increasing by a massive level – in 2008 the only person there’ll be an estimated 49 million PDAs sold around the world.

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

– The platform by which users access your site is normally far less expected when using mobile phone devices. Computer-based website visitors generally simply differ from the other in their internet browser and os (i. vitamin e. most people will make use of a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs change can dramatically.

Which usually mobile phones and PDAs should you consider?

Mobiles and PDAs can differ from a another significantly, and this definitely will radically alter how people experience and use websites. Some of the ways in which handheld products can differ consist of:

– Screen-size (small or large)

– Display layout (portrait vs . landscape)

— Input device (stylus, www.afropress.co.uk numeric keypad, dial-wheel, QWERTY keypad)

Because the mobile phone / PERSONAL DIGITAL ASSISTANT that someone is using will have this sort of a powerful effect on all their experience of your websites, you should try to test with numerous mobile phones and PDAs as it can be.

Of course , testing with every cellular phone and PDA is improbable. Here are some guidelines to help narrow down the number of gadgets you’ll need to evaluation with:

– Your mobile phone site visitors could belong to a specific audience. Specified audiences usually prefer particular types of phones (e. g. mobile handsets with big screens that are designed to support web based access vs . small-screen models that aren’t).
– You will discover ‘phone families’ that offer the same user knowledge (and will not need to be examined individually).
— You may want to00 test while using most well-known mobile phones in Europe or maybe the most popular 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 intend to conduct the mobile phone usability testing sessions with should, of course , rely upon your particular business and its target audience. Some things to make note of include:

– How much knowledge they should have got of employing their mobile phones to locate services. This really is particularly crucial as the market to get accessing on the net services through mobile phones keeps growing and the percent of ‘complete novices’ (i. e. people using the technology for the first time) will be considerably higher than meant for computer users of your website.
– Which cellphone or PERSONAL DIGITAL ASSISTANT they have. We might usually recommend that people employ their own cellphone in a workout, so the test can concentrate on your website not on the way the handheld device functions.

Just where should mobile usability testing sessions always be conducted?

Mobiles and PDAs are used inside the real world thus usability evaluating of hand held devices should certainly therefore not merely take place in a usability lab.

Where, once and how a mobile phone is utilized is critical into a person’s experience of the site they may be accessing. Any of the following conditions could effect this experience and therefore considerations of the site’s usability:

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

As such, we’d recommend, when possible, that virtually any mobile phone and PDA user friendliness testing can be conducted in a clinical and also inside the ‘outside world’.

How you method and operate mobile phone usability sessions will be based on your business and its target audience, but the most popular strategies of mobile simplicity testing include:

– Lab-based (using a camera to record the session)
– Diary-studies (asking people to keep a journal of how they may have used their very own mobile phone and any challenges they encounter)
– Paper documents prototypes (running usability examining on a paper-based version of this site, employing mobile phone screen-sized pieces of paper)
