Cellular phone and PDA usability tests is critical on your business. In fact , mobile and handheld user friendliness testing could be even more important than computer-based usability testing. The key reasons for this are:
– The number of people accessing the Internet from mobile phone and portable devices is certainly increasing for a massive fee – in 2008 alone there’ll be an estimated 58 million PDAs sold across the world.
— People generally have a lot less experience of using their mobile going online than they do of using their pc. This means that computer-based users may be assumed to have a higher level of existing expertise than mobile and handheld users.
— The platform by which users get your site is usually far less expected when using mobile phone devices. Computer-based website visitors generally only differ from the other in their browser and os (i. e. most people will make use of a screen, mouse and keyboard), whereas the several types of mobile phones and PDAs are different can dramatically.
Which in turn mobile phones and PDAs do you need to consider?
Mobile phone devices and PDAs can differ from a single another substantially, and this definitely will radically improve how persons experience and use websites. Some of the ways handheld units can differ involve:
– Screen size (small or large)
– Display layout (portrait vs . landscape)
— Input product (stylus, webinar.paradigma.center numeric pad, dial-wheel, QWERTY keypad)
Because the cellphone / PERSONAL DIGITAL ASSISTANT that an individual is applying will have this sort of a deep effect on the experience of your websites, you should try to test with several mobile phones and PDAs as is feasible.
Of course , examining with every mobile phone and PDA is hopeless. Here are some guidelines to help reduce the number of equipment you’ll need to test out with:
– Your mobile site visitors may possibly belong to a particular audience. Selected audiences are more likely to prefer particular types of phones (e. g. cellular phones with big screens that are designed to support on-line access or small-screen types that aren’t).
– You will discover ‘phone families’ that offer the same user experience (and is not going to need to be analyzed individually).
– You may only want to test while using most well-known mobile phones in Europe or maybe the most popular models that are being used to get your site (you can check your site stats to find out this kind of information).
Who do you wish to test with?
The people you intend to conduct your mobile phone usability testing lessons with can, of course , depend on your particular business and its target market. Some things to make note of include:
— How much encounter they should own of employing their mobile phones gain access to services. This can be particularly important as the market designed for 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 a good deal higher than intended for computer users of your website.
– Which cellphone or PDA they have. We would usually recommend that people work with their own mobile phone in a workout, so the evaluation can concentrate on your website and not just on the way the handheld device works.
Just where should portable usability diagnostic tests sessions always be conducted?
Mobile phones and PDAs are used inside the real world hence usability examining of handheld devices should therefore not only take place in a usability clinical.
Where, when ever and how a mobile phone is used is critical to a person’s connection with the site they are accessing. The following situations could affect this encounter and therefore factors of the web site’s usability:
– Background noises
– Contingency 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 functionality testing is definitely conducted in a lab and also in the ‘outside world’.
How you package and work mobile phone functionality sessions depends on your organization and its target audience, but the the majority of popular techniques of mobile user friendliness testing contain:
– Lab-based (using a camera to record the session)
– Diary-studies (asking people to continue a diary of how they have used their very own mobile phone and any challenges they encounter)
– Paper documents prototypes (running usability evaluating on a paper based version with the site, using mobile phone screen-sized pieces of paper)
