WebEx and GoToMeeting are the most commonly used technologies to conduct a synchronous remote usability test.[4] However, synchronous remote testing may lack the immediacy and sense of "presence" desired to support a collaborative testing process. Moreover, managing inter-personal dynamics across cultural and linguistic barriers may require approaches sensitive to the cultures involved. Other disadvantages include having reduced control over the testing environment and the distractions and interruptions experienced by the participants' in their native environment.[5] One of the newer methods developed for conducting a synchronous remote usability test is by using virtual worlds.[6]
