Mobile & Handheld User friendliness Testing — Why It Matters

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

– The number of persons accessing the online world from portable and hand held devices is usually increasing in a massive price – in 2008 only there’ll end up being an estimated 49.50 million PDAs sold all over the world.

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

— The platform by which users gain access to your site can be far less predictable when using cellphones. Computer-based website visitors generally just differ from one other in their internet browser and os (i. at the. most people will make use of a screen, mouse button and keyboard), whereas the various types of mobile phones and PDAs differ can drastically.

Which in turn mobile phones and PDAs do you need to consider?

Mobile phones and PDAs can differ from one another drastically, and this will radically modify how persons experience and use websites. Some of the ways that handheld units can differ incorporate:

– Screen size (small versus large)

– Display layout (portrait vs . landscape)

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

Because the cellular phone / PERSONAL DIGITAL ASSISTANT that an individual is using will have this sort of a powerful effect on the experience of your webblog, you should try to test with as much mobile phones and PDAs as possible.

Of course , diagnostic tests with every mobile phone and PDA is unattainable. Here are some guidelines to help focus the number of gadgets you’ll need to test out with:

– Your cell site visitors could belong to a selected audience. Selected audiences usually prefer particular types of phones (e. g. mobile phones with big screens that will support on-line access versus small-screen models that aren’t).
– There are ‘phone families’ that offer a very similar user encounter (and is not going to need to be examined individually).
— You may only want to test while using the most well-known mobile phones in Europe or maybe the most popular models that are to be used to gain access to your site (you actually can check your site figures to find out this information).

Who do you wish to test with?

The people you want to conduct the mobile phone user friendliness testing consultations with can, of course , be based upon your particular business and its crowd. Some things to make note of include:

— How much encounter they should have got of using their mobile phones to reach services. This can be particularly important as the market with respect to accessing on the net services through mobile phones is growing and the percent of ‘complete novices’ (i. e. persons using the technology for the first time) will be a long way higher than for computer users of the website.
– Which mobile phone or PDA they have. We would usually recommend that people apply their own mobile phone in a workout, so the check can concentrate on your website certainly not on the way the hand-held device works.

Where should cell usability tests sessions always be conducted?

Cell phones and PDAs are used inside the real world hence usability evaluating of portable devices will need to therefore not simply take place in a usability laboratory.

Where, the moment and how a mobile phone is used is critical into a person’s experience of the site they are simply accessing. Any of the following instances could influence this knowledge and therefore things to consider of the web site’s usability:

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

As such, we would recommend, if you can, that any mobile phone and PDA wonderful testing is normally conducted at a clinical and also inside the ‘outside world’.

How you prepare and manage mobile phone simplicity sessions will be based on your organization and its audience, but the the majority of popular strategies of mobile user friendliness testing include:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to retain a journal of how they may have used all their mobile phone and any problems they encounter)
– Magazine prototypes (running usability evaluating on a paper-based version from the site, applying mobile phone screen-sized pieces of paper)
