Handheld Devices Usability Testing — Why This Matters




  • このエントリーをはてなブックマークに追加

Mobile phone and PDA usability diagnostic tests is critical to your business. Actually mobile and handheld user friendliness testing could be even more important than computer-based usability testing. The primary reasons for this kind of are:

– The number of persons accessing the web from cellular and hand held devices is definitely increasing for a massive pace – in 2008 by themselves there’ll always be an estimated 54.99 million PDAs sold world-wide.

— People generally have way less experience of using their mobile to go online than they do of using their pc. This means that computer-based users may be assumed to possess a higher level of existing expertise than mobile and handheld www.hms-watchstore.com users.

— The platform whereby users access your site is normally far less foreseeable when using cell phones. Computer-based prospects generally just differ from each other in their browser and operating-system (i. e. most people will use a screen, mouse and keyboard), whereas the different types of mobile phones and PDAs vary can considerably.

Which in turn mobile phones and PDAs must you consider?

Mobiles and PDAs can differ from one another significantly, and this is going to radically adjust how people experience and use websites. Some of the ways in which handheld units can differ consist of:

– Screen-size (small versus large)

– Display screen Can i buy lexapro in spain layout (portrait vs . landscape)

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

Because the cellular phone / PERSONAL DIGITAL ASSISTANT that somebody is using will have this kind of a powerful effect on their very own experience of your web sites, you should try to evaluate with as much mobile phones and PDAs as is possible.

Of course , evaluating with every mobile phone and PERSONAL DIGITAL ASSISTANT is very unlikely. Here are some guidelines to help narrow down the number of devices you’ll need to test out with:

– Your portable site visitors might belong to a certain audience. Selected audiences usually 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 find ‘phone families’ that offer the same user encounter (and will not need to be analyzed individually).
– You may only want to test with all the most well-known mobile phones in Europe or maybe the most popular models that are being used to gain access to your site (you can look at your site stats to find out this kind of information).

Who do you wish to test with?

The people you wish to conduct the mobile phone functionality testing periods with can, of course , rely upon your particular business and its audience. Some things to make note of include:

– How much experience they should contain of employing their mobile phones to gain access to services. This really is particularly significant as the market for the purpose of accessing online 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 long way higher than for computer users of your website.
– Which cellular phone or PDA they have. We might usually recommend that people make use of their own mobile phone in a workout, so the evaluation can give attention to your website and not on the way the hand-held device functions.

Wherever should portable usability assessment sessions become conducted?

Cell phones and PDAs are used inside the real world so usability evaluating of portable devices should therefore not only take place in a usability lab.

Where, the moment and how a mobile phone is used is critical into a person’s experience of the site they are simply accessing. Some of the following conditions could influence this experience and therefore factors of the site’s usability:

– Lighting
— Background noise
– Disruptions
– Contingency tasks (i. e. nearly anything the person does at the same time)
– Physical movement

As such, we would recommend, if at all possible, that any kind of mobile phone and PDA usability testing is conducted in a lab and also inside the ‘outside world’.

How you program and manage mobile phone usability sessions depends on your business and its target audience, but the many popular strategies of mobile simplicity testing involve:

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