Functional reactive programming

Abstract

In this paper, we consider using reactive functional programming techniques in F#. We share our experience of using those techniques in developing natural user interface based on Kinect and Leap Motion sensors, and in controlling TRIK robotics toolset, and describe the project of a robotics platform, remotely controlled by gestures. We demonstrate how nicely reactive functional programming can be implemented on multiple platforms using F# programming language, and how streams of events can span boundaries of an isolated system in distributed environment. We also describe Kinect-based physical activity tracker project that uses reactive functional programming approach.
