Handheld Devices User friendliness Testing — Why It Important


Cellphone and PDA usability screening is critical to your business. In fact , mobile and handheld simplicity testing could possibly be even more important than computer-based wonderful testing. The main reasons for this kind of are:

– The number of people accessing the Internet from portable and hand held devices is normally increasing in a massive cost – in 2008 exclusively there’ll be an estimated fifty eight million PDAs sold worldwide.

— People generally have a lot less experience of utilizing their mobile to go online than they do of using their computer system. This means that computer-based users can be assumed to get a higher level of existing expertise than mobile and handheld users.

– The platform whereby users access your site is usually far less predictable when using mobile phone devices. Computer-based website visitors generally just differ from the other person in their internet browser and os (i. y. most people will make use of a screen, mouse button and keyboard), whereas the various types of mobile phones and PDAs vary can dramatically.

Which in turn mobile phones and PDAs must you consider?

Cellphones and PDAs can differ from another dramatically, and this will certainly radically modification how people experience and use websites. Some of the ways in which handheld devices can differ contain:

– Screen-size (small vs . large)

– Display layout (portrait vs . landscape)

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

Because the cellular phone / PDA that an individual is applying will have such a outstanding effect on the experience of your web site, you should try to check with as many mobile phones and PDAs as possible.

Of course , evaluating with every cellular phone and PDA is hopeless. Here are some ideas to help narrow down the number of products you’ll need to test with:

– Your portable site visitors might belong to a particular audience. A number of audiences are more likely to prefer particular types of phones (e. g. mobile phones with big screens that will support on the net access versus small-screen designs that aren’t).
– You will discover ‘phone families’ that offer a very similar user encounter (and will not need to be analyzed individually).
— You may want to00 test with all the most well-liked mobile phones in Europe or the most well-liked models that are being used to access your site (you actually can check your site statistics to find out this kind of information).

Who do you need to test with?

The people you want to conduct the mobile phone simplicity testing trainings with will, of course , be based upon your particular organization and its crowd. Some things to make note of include:

– How much experience they should contain of employing their mobile phones to gain access to services. This is certainly particularly crucial as the market with regards 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 very good higher than pertaining to computer users of your website.
– Which mobile phone or PDA they have. We would usually suggest that people use their own cellular phone in a practice session, so the test can give attention to your website but not on the way the hand-held device works.

Exactly where should mobile phone usability assessment sessions be conducted?

Cell phones and PDAs are used in the real world so usability evaluating of hand held devices should certainly therefore not merely take place in a usability laboratory.

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

– Lighting
– Background noises
– Interruptions
– 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 simplicity testing is usually conducted at a laboratory and also inside the ‘outside world’.

How you plan and work mobile phone functionality sessions depends on your organization and its projected audience, but the most popular methods 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 particular mobile phone and any problems they encounter)
– Daily news prototypes (running usability tests on a paper-based version on the site, using mobile phone screen-sized pieces of paper)
