Cellphone and PDA usability assessment is critical to your business. In fact , mobile and handheld user friendliness testing could be even more important than computer-based user friendliness testing. The key reasons for this are:
— The number of people accessing the Internet from mobile phone and handheld devices is usually increasing in a massive cost – in 2008 alone there’ll be an estimated 49 million PDAs sold world-wide.
– People generally have a lot less experience of utilizing their mobile to move online than they do of using their pc. This means that computer-based users could 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 is usually far less predictable when using mobiles. Computer-based website visitors generally just differ from each other in their web browser and operating-system (i. y. most people will use a screen, mouse button and keyboard), whereas the several types of mobile phones and PDAs change can dramatically.
Which usually mobile phones and PDAs should you consider?
Cellphones and PDAs can differ from another substantially, and this might radically switch how persons experience and use websites. Some of the ways handheld gadgets can differ contain:
– Screen-size (small versus large)
– Display screen layout (portrait vs . landscape)
— Input unit (stylus, estadisticas.cne.gob.sv numeric keypad, dial-wheel, QWERTY keypad)
Because the mobile phone / PDA that an individual is employing will have these kinds of a unique effect on their particular experience of your web sites, you should try to evaluate with as much mobile phones and PDAs as it can be.
Of course , examining with every mobile phone and PDA is unachievable. Here are some guidelines to help narrow down the number of devices you’ll need to test with:
— Your mobile phone site visitors may possibly belong to a particular audience. A number of audiences are inclined to prefer particular types of phones (e. g. handsets with big screens that will support on the web access vs . small-screen types that aren’t).
– You will discover ‘phone families’ that offer the same user knowledge (and will not likely need to be examined individually).
— You may want to00 test together with the most popular mobile phones in Europe or the most popular models that are being used to get your site (you actually can check your site statistics to find out this kind of information).
Who do you need to test with?
The people you would like to conduct the mobile phone usability testing sessions with will, of course , depend on your particular business and its visitors. Some things to bear in mind include:
— How much knowledge they should have got of using their mobile phones to locate services. This really is particularly crucial as the market for the purpose of accessing web based services through mobile phones is growing and the percent of ‘complete novices’ (i. e. persons using the technology for the first time) will be far higher than just for computer users of the website.
– Which cellular phone or PDA they have. We would usually suggest that people work with their own cellular phone in a procedure, so the test out can concentrate on your website certainly not on the way the handheld device performs.
Where should cellular usability assessment sessions always be conducted?
Cell phones and PDAs are used inside the real world and so usability diagnostic tests of portable devices will need to therefore not simply take place in a usability laboratory.
Where, once and how a mobile phone can be used is critical into a person’s connection with the site they are really accessing. Some following circumstances could influence this experience and therefore factors of the web site’s usability:
— Lighting
— Background sound
– Interruptions
– Concurrent tasks (i. e. anything the person does at the same time)
– Physical movement
As such, there was recommend, when possible, that virtually any mobile phone and PDA functionality testing can be conducted in a laboratory and also inside the ‘outside world’.
How you system and manage mobile phone usability sessions will be based on your organization and its market, but the the majority of popular techniques of mobile simplicity testing incorporate:
– 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 mobile phone and any challenges they encounter)
– Newspaper prototypes (running usability testing on a paper-based version in the site, applying mobile phone screen-sized pieces of paper)
