Cellphone and PDA usability screening is critical to your business. Actually mobile and handheld usability testing could possibly be even more important than computer-based wonderful testing. The primary reasons for this kind of are:
— The number of persons accessing the world wide web from portable and portable devices can be increasing for a massive fee – in 2008 together there’ll be an estimated 58 million PDAs sold global.
— People generally have way less experience of utilizing their mobile to get online than they do of using their laptop. This means that computer-based users can be assumed to have a higher level of existing expertise than mobile and handheld users.
– The platform by which users gain access to your site is certainly far less estimated when using cellphones. Computer-based website visitors generally simply differ from each other in their internet browser and main system (i. electronic. most people will use a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs differ can substantially.
Which mobile phones and PDAs should you consider?
Mobile phone devices and PDAs can differ from a another significantly, and this can radically modification how people experience and use websites. Some of the ways in which handheld equipment can differ include:
– Screen-size (small or large)
– Display layout (portrait vs . landscape)
– Input unit (stylus, dlaughters.com numeric pad, dial-wheel, QWERTY keypad)
Because the cellular phone / PDA that someone is using will have these kinds of a profound effect on their particular experience of your web sites, you should try to try with several mobile phones and PDAs as is feasible.
Of course , screening with every cellular phone and PERSONAL DIGITAL ASSISTANT is very unlikely. Here are some suggestions to help narrow down the number of units you’ll need to test out with:
— Your mobile phone site visitors might belong to a particular audience. Several audiences usually tend to prefer particular types of phones (e. g. cell phones with big screens that can support online access vs . small-screen models that aren’t).
– You will discover ‘phone families’ that offer the same user encounter (and will never need to be examined individually).
– You may only want to test with all the most well-known mobile phones in Europe or the most well-known models that are to be used to gain access to your site (you can look at your site statistics to find out this kind of information).
Who do you want to test with?
The people you would like to conduct the mobile phone user friendliness testing sessions with should, of course , be based upon your particular organization and its visitors. Some things to keep in mind include:
– How much experience they should possess of using their mobile phones to view services. This can be particularly crucial as the market intended for accessing web based services through mobile phones keeps growing and the percent of ‘complete novices’ (i. e. persons using the technology for the first time) will be a lot higher than for the purpose of computer users of your website.
— Which cellphone or PDA they have. We might usually advise that people use their own cellphone in a time, so the test out can give attention to your website certainly not on the way the hand-held device functions.
Wherever should mobile phone usability screening sessions always be conducted?
Mobiles and PDAs are used in the real world and so usability evaluating of portable devices will need to therefore not merely take place in a usability lab.
Where, when and how a mobile phone is employed is critical into a person’s connection with the site they can be accessing. Many of the following situations could effect this experience and therefore things to consider of the website’s usability:
– Lighting
— Background sound
– Disruptions
– Contingency tasks (i. e. whatever the person has been doing at the same time)
– Physical movement
As such, we’d recommend, if you can, that any mobile phone and PDA functionality testing can be conducted both in a lab and also in the ‘outside world’.
How you system and work mobile phone usability sessions will be based on your business and its market, but the the majority of popular methods of mobile simplicity testing contain:
– Lab-based (using a camera to record the session)
– Diary-studies (asking people to keep a diary of how they have used their particular mobile phone and any concerns they encounter)
– Paper prototypes (running usability tests on a paper-based version of the site, using mobile phone screen-sized pieces of paper)
