Handheld Devices Usability Testing – Why It Important

Cellular phone and PDA usability diagnostic tests is critical on your business. Actually mobile and handheld simplicity testing could be even more important than computer-based wonderful testing. The primary reasons for this are:

— The number of people accessing the online world from cellular and handheld devices is normally increasing by a massive pace – in 2008 together there’ll become an estimated fifty eight million PDAs sold globally.

— People generally have much less experience of employing their mobile to search online than they do of using their computer system. This means that computer-based users may 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 far less foreseen when using mobile phones. Computer-based guests generally only differ from one another in their browser and operating-system (i. y. most people will make use of a screen, mouse button and keyboard), whereas the several types of mobile phones and PDAs change can greatly.

Which will mobile phones and PDAs do you need to consider?

Mobiles and PDAs can differ from a single another substantially, and this will radically adjust how people experience and use websites. Some of the ways handheld devices can differ consist of:

– Screen size (small versus large)

– Display layout (portrait vs . landscape)

– Input system (stylus, numeric pad, dial-wheel, QWERTY keypad)

Because the cellphone / PERSONAL DIGITAL ASSISTANT that an individual is employing will have such a outstanding effect on the experience of your web site, you should try to check with several mobile phones and PDAs as it can be.

Of course , screening with every cellular phone and PERSONAL DIGITAL ASSISTANT is extremely hard. Here are some suggestions to help narrow down the number of gadgets you’ll need to check with:

— Your cellular site visitors may belong to a certain audience. Selected audiences normally prefer particular types of phones (e. g. phones with big screens that are designed to support on line access or small-screen products that aren’t).
– You will discover ‘phone families’ that offer a very similar user encounter (and will never need to be examined individually).
— You may only want to test while using most well-known mobile phones in Europe as well as most well-known models that are to be used to access your site (you actually can look at your site stats to find out this kind of information).

Who do you need to test with?

The people you need to conduct your mobile phone simplicity testing classes with is going to, of course , rely upon your particular organization and its target market. Some things to make note of include:

— How much experience they should have of using their mobile phones to reach services. This is particularly significant as the market with respect to accessing web based services through mobile phones is growing and the percent of ‘complete novices’ (i. e. persons using the technology for the first time) will be even higher than with respect to computer users of your website.
— Which cellphone or PDA they have. We might usually recommend that people use their own cellular phone in a procedure, so the evaluation can give attention to your website and necessarily on the way the handheld device works.

Where should portable usability examining sessions become conducted?

Mobiles and PDAs are used inside the real world and so usability assessment of handheld devices ought to therefore not simply take place in a usability lab.

Where, when ever and how a mobile phone is utilized is critical to a person’s connection with the site they are accessing. Some following conditions could effect this experience and therefore factors of the site’s usability:

— Lighting
— Background noise
– Interruptions
– Contingency tasks (i. e. anything the person has been doing at the same time)
– Physical movement

As such, we would recommend, if at all possible, that virtually any mobile phone and PDA user friendliness testing can be conducted in a laboratory and also in the ‘outside world’.

How you prepare and run mobile phone simplicity sessions depends on your organization and its crowd, but the many popular strategies of mobile wonderful testing incorporate:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to keep a diary of how they may have used their mobile phone and any concerns they encounter)
– Paper prototypes (running usability examining on a paper based version with the site, using mobile phone screen-sized pieces of paper)
