Cellular phone and PDA usability testing is critical on your business. In fact , mobile and handheld functionality testing could be even more important than computer-based functionality testing. The key reasons for this are:
— The number of persons accessing the net from cellular and hand held devices is definitely increasing for a massive pamflet.or.id pace – in 2008 on it’s own there’ll be an estimated 58 million PDAs sold international.
— People generally have a lot less experience of utilizing their mobile to travel online than they do of using their computer. This means that computer-based users can 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 certainly far less expected when using cell phones. Computer-based site visitors generally just differ from each other in their browser and os (i. elizabeth. most people will use a screen, mouse and keyboard), whereas the different types of mobile phones and PDAs change can significantly.
Which mobile phones and PDAs must you consider?
Cell phones and PDAs can differ derived from one of another drastically, and this will radically modification how persons experience and use websites. Some of the ways handheld units can differ contain:
– Screen-size (small vs . large)
– Screen layout (portrait vs . landscape)
— Input device (stylus, numeric pad, dial-wheel, QWERTY keypad)
Because the cellphone / PDA that somebody is using will have such a outstanding effect on their very own experience of your blog, you should try to test with several mobile phones and PDAs as is possible.
Of course , assessment with every mobile phone and PDA is extremely hard. Here are some tips to help narrow down the number of gadgets you’ll need to check with:
– Your cell site visitors may belong to a unique audience. Selected audiences normally prefer particular types of phones (e. g. cellular phones with big screens that are designed to support web based access vs . small-screen products 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 most popular mobile phones in Europe as well as most popular models that are to be used to access your site (you actually can check your site stats to find out this information).
Who do you want to test with?
The people you wish to conduct the mobile phone simplicity testing periods with might, of course , depend on your particular organization and its readership. Some things to keep in mind include:
– How much knowledge they should contain of using their mobile phones to access services. This really is particularly significant as the market meant for 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 a good deal higher than just for computer users of your website.
— Which mobile phone or PDA they have. We would usually recommend that people apply their own cellphone in a practice session, so the test out can give attention to your website and not just on the way the hand-held device functions.
Where should portable usability examining sessions be conducted?
Cell phones and PDAs are used in the real world therefore usability testing of handheld devices should therefore not only take place in a usability laboratory.
Where, once and how a mobile phone is employed is critical to a person’s experience of the site they are accessing. Many of the following conditions could impact this knowledge and therefore concerns of the website’s usability:
– Background noises
– 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 kind of mobile phone and PDA functionality testing is definitely conducted both in a laboratory and also inside the ‘outside world’.
How you schedule and operate mobile phone simplicity sessions depends on your organization and its target market, but the many popular strategies of mobile user friendliness testing contain:
– Lab-based (using a camera to record the session)
— Diary-studies (asking people to hold a journal of how they have used their particular mobile phone and any problems they encounter)
– Daily news prototypes (running usability diagnostic tests on a paper-based version with the site, using mobile phone screen-sized pieces of paper)
