Cellphone and PDA usability testing is critical on your business. In fact , mobile and handheld user friendliness testing could be even more important than computer-based simplicity testing. The key reasons for this kind of are:
— The number of people accessing the Internet from mobile phone and handheld devices is usually increasing in a massive charge – in 2008 together there’ll become an estimated 54.99 million PDAs sold worldwide.
– People generally have a lot less experience of employing their mobile to go online than they do of using their computer. This means that computer-based users may be assumed to have a higher level of existing expertise than mobile and handheld users.
— The platform whereby users get your site is definitely far less predictable when using mobile phone devices. Computer-based website visitors generally simply differ from the other in their internet browser and os (i. y. most people will use a screen, mouse button and keyboard), whereas the different types of mobile phones and PDAs change can dramatically.
Which usually mobile phones and PDAs should you consider?
Mobile phone devices and PDAs can differ derived from one of another substantially, and this can radically improve how people experience and use websites. Some of the ways handheld equipment can differ incorporate:
– Screen-size (small or large)
– Display screen layout (portrait vs . landscape)
— Input unit (stylus, www.nvmilano.com numeric keypad, dial-wheel, QWERTY keypad)
Because the mobile phone / PERSONAL DIGITAL ASSISTANT that someone is using will have this kind of a outstanding effect on their very own experience of your websites, you should try to try with as much mobile phones and PDAs as is possible.
Of course , testing with every cellular phone and PERSONAL DIGITAL ASSISTANT is unachievable. Here are some ideas to help reduce the number of units you’ll need to evaluation with:
– Your cell site visitors may possibly belong to a unique audience. A number of audiences often prefer particular types of phones (e. g. mobile handsets with big screens that will support on line access or small-screen types that aren’t).
– You will discover ‘phone families’ that offer a very similar user experience (and is not going to need to be examined individually).
— You may only want to test while using most popular mobile phones in Europe or maybe the most popular models that are being used to access your site (you actually can look at your site statistics to find out this kind of information).
Who do you want to test with?
The people you want to conduct the mobile phone usability testing visits with should, of course , rely upon your particular business and its customers. Some things to bear in mind include:
— How much encounter they should possess of using their mobile phones to locate services. This really is particularly crucial as the market pertaining to accessing over the internet services through mobile phones keeps growing and the percent of ‘complete novices’ (i. e. people using the technology for the first time) will be far higher than for computer users of the website.
– Which cellphone or PERSONAL DIGITAL ASSISTANT they have. We would usually recommend that people apply their own cellular phone in a session, so the check can give attention to your website but not on the way the handheld device performs.
In which should cellular usability testing sessions be conducted?
Mobiles and PDAs are used in the real world consequently usability evaluating of handheld devices should certainly therefore not only take place in a usability lab.
Where, once and how a mobile phone can be used is critical to a person’s experience of the site they may be accessing. The following conditions could affect this encounter and therefore concerns of the web site’s usability:
— Lighting
— Background sound
– Disruptions
– Concurrent tasks (i. e. whatever the person is performing at the same time)
– Physical movement
As such, we’d recommend, whenever possible, that any kind of mobile phone and PDA functionality testing is definitely conducted at a laboratory and also in the ‘outside world’.
How you system and work mobile phone wonderful sessions depends on your business and its crowd, but the most popular strategies of mobile user friendliness testing contain:
– Lab-based (using a camera to record the session)
— Diary-studies (asking people to maintain a journal of how they have used their particular mobile phone and any challenges they encounter)
– Standard paper prototypes (running usability assessment on a paper-based version for the site, applying mobile phone screen-sized pieces of paper)
