Towards the perfect infrastructure for usability testing on mobile devices.

ABSTRACTIn this paper, we describe various setups that allow usability professionals to conduct effective user studies on mobile devices. We describe the factors relevant when building a solution for mobile device observation and the various designs we worked with in the Google user experience research environment as we iterated to meet changing study needs. We highlight several systems that can successfully be used in an industry environment, including a novel setup that is fully portable, can be used in a usability lab as well as in the field, accommodates a large variety of different mobile devices, and allows for live observation by product teams around the world.
