ViewFinder is a cross-platform mobile application made to support the installation and reconfiguration of marker-based motion capture systems with multiple cameras.
ViewFinder addresses a common issue when installing or reconfiguring motion capture systems: that system components such as cameras and the host computer can be physically separate and/or difficult to reach, requiring personnel to maneuver between them frequently and laboriously. ViewFinder allows setup technicians or endusers to visualize the output of each camera in the system in a variety of ways in real time, on a smartphone or tablet, while also providing a means to make adjustments to system parameters such as exposure or marker thresholds on the fly. The app has been designed and evaluated through a process observing user-centered design principles, and effectively reduces the amount of work involved in installing and reconfiguring motion capture systems.
ViewFinder is based on previous work by the development team at Qualisys AB, and an interaction design master's thesis project by Emmanuel Batis and Mathias Bylund at Chalmers University of Technology.
