Handheld Devices Functionality Testing — Why This Important

Mobile phone and PDA usability diagnostic tests is critical on your business. In fact , mobile and handheld user friendliness testing could be even more important than computer-based user friendliness testing. The main reasons for this are:

– The number of persons accessing the online world from portable and handheld devices is certainly increasing for a massive pace – in 2008 exclusively there’ll end up being an estimated 49 million PDAs sold globally.

— People generally have much less experience of employing their mobile to move online than they do of using their computer system. 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 get your site is usually far less foreseen when using mobile phone devices. Computer-based site visitors generally only differ from the other in their internet browser and os (i. y. most people will use a screen, mouse button and keyboard), whereas different types of mobile phones and PDAs change can drastically.

Which will mobile phones and PDAs should you consider?

Cell phones and PDAs can differ from a single another significantly, and this should radically adjust how people experience and use websites. Some of the ways that handheld gadgets can differ contain:

– Screen size (small or large)

– Display layout (portrait vs . landscape)

— Input device (stylus, numeric keypad, dial-wheel, QWERTY keypad)

Because the cellphone / PERSONAL DIGITAL ASSISTANT that someone is using will have such a unique effect on all their experience of your websites, you should try to check with as many mobile phones and PDAs as possible.

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

– Your portable site visitors may possibly belong to a specialized audience. Selected audiences are more likely to prefer particular types of phones (e. g. cellular phones with big screens that can support on line access versus small-screen designs that aren’t).
– You will discover ‘phone families’ that offer a very similar user knowledge (and is not going to need to be analyzed individually).
— You may only want to test while using most popular mobile phones in Europe as well as most popular models that are to be used to get your site (you actually can look at your site stats to find out this information).

Who do you need to test with?

The people you wish to conduct your mobile phone usability testing consultations with will certainly, of course , be based upon your particular organization and its customers. Some things to keep in mind include:

— How much encounter they should currently have of using their mobile phones to locate services. This is certainly particularly crucial as the market designed for accessing on the web 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 lot higher than pertaining to computer users of the website.
— Which mobile phone or PDA they have. We would usually recommend that people work with their own cellular phone in a practice session, so the test can give attention to your website and not just on the way the hand-held device works.

Where should mobile usability diagnostic tests sessions become conducted?

Mobile phones and PDAs are used in the real world so usability assessment of hand held devices will need to therefore not simply take place in a usability lab.

Where, when and how a mobile phone is needed is critical into a person’s connection with the site they may be accessing. Many of the following conditions could affect this encounter and therefore things to consider of the web site’s usability:

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

As such, there was recommend, if you can, that any kind of mobile phone and PDA user friendliness testing can be conducted in a clinical and also inside the ‘outside world’.

How you program and operate mobile phone functionality sessions will be based on your business and its projected audience, but the many popular strategies to mobile wonderful testing consist of:

– Lab-based (using a camera to record the session)
— Diary-studies (asking people to maintain a diary of how they have used their particular mobile phone and any challenges they encounter)
– Traditional prototypes (running usability examining on a paper-based version belonging to the site, employing mobile phone screen-sized pieces of paper)
