Cellphone and PDA usability testing is critical to your business. Actually mobile and handheld user friendliness testing could possibly be even more important than computer-based user friendliness testing. The main reasons for this kind of are:
– The number of persons accessing the online world from cell and hand held devices is usually increasing for a massive rate – in 2008 by itself there’ll become an estimated fifty eight million PDAs sold global.
– People generally have way less experience of employing their mobile to continue 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 is usually far less predictable when using mobile phone devices. Computer-based guests generally only differ from each other in their web browser and main system (i. y. most people will make use of a screen, mouse and keyboard), whereas different types of mobile phones and PDAs vary can dramatically.
Which mobile phones and PDAs should you consider?
Mobiles and PDAs can differ from another substantially, and this will certainly radically switch how people experience and use websites. Some of the ways in which handheld devices can differ consist of:
– Screen size (small or large)
– Display layout (portrait vs . landscape)
— Input equipment (stylus, webinar.paradigma.center numeric keypad, dial-wheel, QWERTY keypad)
Because the cellular phone / PDA that an individual is using will have this kind of a unique effect on their particular experience of your webblog, you should try to check with several mobile phones and PDAs as is possible.
Of course , screening with every cellular phone and PDA is hopeless. Here are some suggestions to help narrow down the number of equipment you’ll need to evaluation with:
– Your cell site visitors might belong to a specific audience. Several audiences are likely to prefer particular types of phones (e. g. mobile phones with big screens that can support on line access versus small-screen styles that aren’t).
– You will find ‘phone families’ that offer a very similar user experience (and will never need to be analyzed individually).
— You may only want to test together with the most well-liked mobile phones in Europe or perhaps the most popular models that are being used to gain access to your site (you actually can look at your site statistics to find out this information).
Who do you wish to test with?
The people you intend to conduct your mobile phone functionality testing visits with will certainly, of course , depend on your particular business and its projected audience. Some things to keep in mind include:
— How much knowledge they should currently have of employing their mobile phones to reach services. This is particularly significant as the market with respect to accessing on line services through mobile phones is growing and the percent of ‘complete novices’ (i. e. people using the technology for the first time) will be way higher than pertaining to computer users of the website.
– Which cellphone or PDA they have. We would usually suggest that people work with their own cellphone in a time, so the check can focus on your website instead of on the way the handheld device performs.
Exactly where should cellular usability examining sessions become conducted?
Cellphones and PDAs are used in the real world thus usability assessment of handheld devices should certainly therefore not simply take place in a usability lab.
Where, when ever and how a mobile phone is employed is critical into a person’s connection with the site they are really accessing. Many of the following circumstances could effect this knowledge and therefore things to consider of the site’s usability:
— Background sound
– Contingency tasks (i. e. whatever the person is doing at the same time)
– Physical movement
As such, we would recommend, if at all possible, that any mobile phone and PDA functionality testing can be conducted in a clinical and also inside the ‘outside world’.
How you prepare and operate mobile phone usability sessions depends on your organization and its target market, but the many popular techniques of mobile user friendliness testing involve:
– Lab-based (using a camera to record the session)
– Diary-studies (asking people to continue to keep a diary of how they may have used their particular mobile phone and any concerns they encounter)
– Paper documents prototypes (running usability assessment on a paper based version of your site, using mobile phone screen-sized pieces of paper)
