Handheld Devices Usability Testing — Why That Matters

Cellular phone and PDA usability assessment is critical on your business. Actually mobile and handheld functionality testing could be even more important than computer-based usability testing. The key reasons for this kind of are:

— The number of people accessing the Internet from portable and handheld devices is increasing for a massive pace – in 2008 upon it’s own there’ll always be an estimated fifty eight million PDAs sold all over the world.

— People generally have a lot less experience of employing their mobile to travel 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 whereby users access your site is far less foreseen when using cell phones. Computer-based site visitors generally only differ from the other person in their browser and os (i. at the. most people will make use of a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs are different can substantially.

Which mobile phones and PDAs do you need to consider?

Cellphones and PDAs can differ in one another noticeably, and this will radically alter how people experience and use websites. Some of the ways in which handheld products can differ include:

– Screen-size (small versus large)

– Display screen layout (portrait vs . landscape)

– Input device (stylus, medoc-care.jp numeric keypad, dial-wheel, QWERTY keypad)

Because the cellular phone / PDA that somebody is employing will have such a outstanding effect on all their experience of your websites, you should try to try with as many mobile phones and PDAs as it can be.

Of course , evaluating with every mobile phone and PDA is impossible. Here are some ideas to help reduce the number of gadgets you’ll need to evaluation with:

– Your mobile site visitors may possibly belong to a selected audience. Certain audiences usually tend to prefer particular types of phones (e. g. cellular phones with big screens that can support on the net access versus small-screen units that aren’t).
– You will discover ‘phone families’ that offer a very similar user knowledge (and will never need to be tested individually).
– You may want to00 test together with the most well-liked mobile phones in Europe as well as most popular models that are to be used to access 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 the mobile phone usability testing visits with is going to, of course , be based upon your particular business and its target market. Some things to keep in mind include:

— How much encounter they should experience of employing their mobile phones gain access to services. This really is particularly crucial as the market for accessing on the web services through mobile phones keeps growing and the percent of ‘complete novices’ (i. e. persons using the technology for the first time) will be a long way higher than pertaining to computer users of the website.
– Which cellular phone or PDA they have. We would usually recommend that people apply their own cellphone in a procedure, so the test can concentrate on your website and not on the way the hand-held device functions.

Exactly where should portable usability evaluating sessions always be conducted?

Cellphones and PDAs are used inside the real world therefore usability diagnostic tests of handheld devices will need to therefore not merely take place in a usability lab.

Where, when and how a mobile phone is used is critical to a person’s connection with the site they are really accessing. Some of the following situations could affect this experience and therefore things to consider of the website’s usability:

– Lighting
— Background noises
– Distractions
– Concurrent tasks (i. e. anything at all the person is doing at the same time)
– Physical movement

As such, we’d recommend, if possible, that virtually any mobile phone and PDA user friendliness testing is conducted both in a laboratory and also in the ‘outside world’.

How you prepare and operate mobile phone usability sessions will be based on your business and its customers, but the most popular methods of mobile wonderful testing incorporate:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to continue to keep a journal of how they have used their mobile phone and any complications they encounter)
– Standard paper prototypes (running usability screening on a paper-based version of your site, using mobile phone screen-sized pieces of paper)
