5 Tips for Conducting a Mobile Usability Test

1.       Have the charger's ready:

The common battery life issues that fatality the cell phone users in general fatality mobile usability tests as well.  About 10 percent of our users run out of the battery during the perusal.  Having iPhone 4 or 5 chargers along with some Android chargers helps to keep the studies executing. It also does not hurt to have a backup Apple and Android phone ready as well.  We generally have the three devices charged or ready in case a participant forgets their phone, it has connectivity issues and has the problems using an application.

2.       Record finger’s, screens or bodies:

Unlike the desktop studies, where a screen recorder like go to the meeting will capture most of the salient processes, mobile screen recorder like Reflectors won't shows you user’s interacting with the device, just the effects of their activities.  You miss a lot of informative fat fingered misses, swipes and gestures as users attempt to navigate with the small mobile interface.  While recording the user's face or body are not as necessary, being able to see participant move with their phone along with the facial expressions can helps the capture those activity of de-light or frustration.

3.       Encourage the users to pick up their phone:

While it is likely the case of some users prefer a stable phone to interact with, few of the placements may be an artifact of the testing & you will want to minimize that favoritism during the study.

4.       Consider running a moderated mobile study:  

Simply a bit more than a year ago the best and only authentic way to observe a participant and use their mobile device was in persons.  Fortunately, technology has come out in the previous year from companies like User's Zoom or User's testing. Com that allow you to watch the users attempt tasks on mobile devices from anywhere in the world.  All of the advantages of                   un-modulated desktop testing apply here too easier recruiting the specialized or geo-graphically diversified users, & speedy collections of much larger sample sizes.

5.       Plan for different platforms:


Android is not as the same experience of iOS.  There are differences in screen sizes or UI conventions, navigation.  While we have to deal with the different browsers or the idiosyncrasies between PC’s or Mac’s for desktop usability testing, the difference between the mobile devices can be even more sub-stantial. Developers are not the only ones, who have to plan & account for these differences; usability experienced professionals also required to recognize & respond to the device or platform variations.
