1. The document describes the development of a remote usability testing system that allows observers to remotely view, record, and analyze test participants using mobile applications on their own devices from any location. 2. The goals of the system were to make mobile usability testing more natural and less intrusive for participants by eliminating the need for specialized software or traveling to a lab, while still allowing observers to see the mobile screen, user's interactions, and voice. 3. The approach involved using a camera to capture the mobile screen, transmitting the video and audio streams to observers, and implementing screen capturing for some devices. This would extend their existing usability lab capabilities to remote mobile testing.
