User interface design consists of a collaborative activity where various stakeholders can all sketch the future interactive system at different levels of fidelity on different devices and computing platforms. User interfaces sketches are also intended to support prototypes on multiple computing platforms and operating systems that all impose their own capabilities and constraints. In order to support the needs for user interface design by sketching, this paper describes Gambit, a multi-platform system that provides a light-weight approach for prototyping graphical user interfaces by sketching with HTML5. The paper reports on an experiment for the most preferred platform/devices for three primary sketching functions by designers and developers in a Gambit-supported session.
