Handheld Devices Simplicity Testing -- Why That Important

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

- The number of persons accessing the online world from mobile and handheld devices is definitely increasing by a massive cost - in 2008 by itself there'll become an estimated 58 million PDAs sold all over the world.

-- People generally have way less experience of employing their mobile to get 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 gain access to your site is far less predictable when using mobiles. Computer-based website visitors generally simply differ from one another in their internet browser and main system (i. at the. most people will make use of a screen, mouse and keyboard), whereas the different types of mobile phones and PDAs fluctuate can significantly.

Which usually mobile phones and PDAs should you consider?

Cellphones and PDAs can differ derived from one of another noticeably, and this can radically transformation how people experience and use websites. Some of the ways handheld products can differ incorporate:

- Screen-size (small or large)

- Display layout (portrait vs . landscape)

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

Because the cellular phone / PDA that an individual is applying will have this sort of a outstanding effect on their very own experience of your internet site, you should try to test with as many mobile phones and PDAs as is possible.

Of course , evaluating with every mobile phone and PERSONAL DIGITAL ASSISTANT is hopeless. Here are some suggestions to help focus the number of units you'll need to test out with:

-- Your mobile phone site visitors could belong to a selected audience. Several audiences are inclined to prefer particular types of phones (e. g. handsets with big screens that will support online access vs . small-screen units that aren't).
- There are 'phone families' that offer the same user experience (and is not going to need to be analyzed individually).
- You may want to00 test along with the most well-known mobile phones in Europe and also the most popular models that are being used to get your site (you actually can check your site statistics to find out this kind of information).

Who do you want to test with?

The people you would like to conduct the mobile phone functionality testing sessions with can, of course , be based upon your particular business and its customers. Some things to make note of include:

- How much encounter they should have of utilizing their mobile phones to locate services. This really is particularly significant as the market pertaining to accessing over the internet services through mobile phones is growing and the percent of 'complete novices' (i. e. persons using the technology for the first time) will be far higher than to get computer users of your website.
-- Which cellphone or PERSONAL DIGITAL ASSISTANT they have. We would usually recommend that people use their own cellular phone in a procedure, so the evaluation can focus on your website instead of on the way the handheld device works.

Exactly where should mobile usability assessment sessions become conducted?

Mobiles and PDAs are used inside the real world and so usability diagnostic tests of handheld devices should certainly therefore not only take place in a usability laboratory.

Where, when and how a mobile phone can be used is critical to a person's connection with the site they are really accessing. One of the following circumstances could affect this knowledge and therefore things to consider of the website's usability:

- Lighting
-- Background noise
- Disruptions
- Contingency tasks (i. e. nearly anything the person is doing at the same time)
- Physical movement

As such, we'd recommend, if possible, that any mobile phone and PDA simplicity testing is conducted both in a clinical and also in the 'outside world'.

How you approach and manage mobile phone functionality sessions will be based on your business and its market, but the most popular strategies to mobile user friendliness testing involve:

- Lab-based (using a camera to record the session)
-- Diary-studies (asking people to maintain a journal of how they may have used the mobile phone and any complications they encounter)
- Paper documents prototypes (running usability diagnostic tests on a paper-based version with the site, using mobile phone screen-sized pieces of paper)
