Cellular phone and PDA usability testing is critical to your business. Actually mobile and handheld user friendliness testing could be even more important than computer-based functionality testing. The key reasons for this kind of are:
— The number of persons accessing the net from portable and hand held devices is certainly increasing in a massive pace – in 2008 only there’ll become an estimated 49 million PDAs sold throughout the world.
– People generally have a lot less experience of employing their mobile to move online than they do of using their laptop. This means that computer-based users could be assumed to get a higher level of existing expertise than mobile and handheld users.
— The platform through which users access your site is normally far less foreseeable when using mobiles. Computer-based website visitors generally only differ from each other in their browser and os (i. e. most people will use a screen, mouse button and keyboard), whereas the several types of mobile phones and PDAs vary can considerably.
Which will mobile phones and PDAs must you consider?
Cell phones and PDAs can differ from one another significantly, and this definitely will radically modification how people experience and use websites. Some of the ways in which handheld units can differ contain:
– Screen size (small or large)
– Display layout (portrait vs . landscape)
— Input machine (stylus, umangworld.com numeric pad, dial-wheel, QWERTY keypad)
Because the cellular phone / PERSONAL DIGITAL ASSISTANT that someone is using will have this sort of a unique effect on their experience of your web blog, you should try to check with as much mobile phones and PDAs as it can be.
Of course , screening with every mobile phone and PDA is unachievable. Here are some suggestions to help narrow down the number of equipment you’ll need to evaluation with:
– Your mobile site visitors might belong to a particular audience. Certain audiences usually prefer particular types of phones (e. g. smartphone with big screens that will support web based access or small-screen products that aren’t).
– There are ‘phone families’ that offer a very similar user encounter (and will not need to be analyzed individually).
— You may only want to test when using the most well-known mobile phones in Europe or perhaps the most well-known models that are to be used to get your site (you actually can look at your site figures to find out this kind of information).
Who do you need to test with?
The people you wish to conduct your mobile phone usability testing periods with can, of course , be based upon your particular organization and its target market. Some things to make note of include:
— How much encounter they should experience of employing their mobile phones to locate services. That is particularly important as the market meant for accessing over the internet 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 lot higher than intended for computer users of your website.
— Which cellphone or PDA they have. We might usually advise that people work with their own cellular phone in a time, so the test can focus on your website and never on the way the handheld device functions.
Where should mobile usability examining sessions always be conducted?
Cell phones and PDAs are used in the real world consequently usability examining of portable devices should therefore not simply take place in a usability laboratory.
Where, the moment and how a mobile phone is used is critical into a person’s experience of the site they may be accessing. Some of the following instances could effect this encounter and therefore factors of the web site’s usability:
– Background noise
– Concurrent tasks (i. e. anything the person has been doing at the same time)
– Physical movement
As such, we’d recommend, if possible, that any kind of mobile phone and PDA usability testing is conducted in a lab and also in the ‘outside world’.
How you arrange and operate mobile phone user friendliness sessions will be based on your organization and its viewers, but the most popular strategies to mobile simplicity testing involve:
– Lab-based (using a camera to record the session)
— Diary-studies (asking people to keep a journal of how they may have used the mobile phone and any concerns they encounter)
– Paper prototypes (running usability tests on a paper based version of your site, employing mobile phone screen-sized pieces of paper)
