What happened to remote usability testing?

The idea of conducting usability tests remotely emerged ten years ago. Since then, it has been studied empirically, and some software organizations employ remote methods. Yet there are still few comparisons involving more than one remote method. This paper presents results from a systematic empirical comparison of three methods for remote usability testing and a conventional laboratory-based think-aloud method. The three remote methods are a remote synchronous condition, where testing is conducted in real time but the test monitor is separated spatially from the test subjects, and two remote asynchronous conditions, where the test monitor and the test subjects are separated both spatially and temporally. The results show that the remote synchronous method is virtually equivalent to the conventional method. Thereby, it has the potential to conveniently involve broader user groups in usability testing and support new development approaches. The asynchronous methods are considerably more time-consuming for the test subjects and identify fewer usability problems, yet they may still be worthwhile.
