HCI (arduino uno + grasshoper)

I'm seeking two different projects of the same principle but different idea's of course, the project should be implemented using an Arduino-Uno and one type of sensor (physical agent) and be designed in Rhino, Grasshopper and interface with Arduino (virtual agent), the project is about recognizing two different gestures using a sensor (of your choice), the grasshopper should reflect the gestures been made skills needed: basic knowledge of rhino, Arduino, and grasshopper more details in attached PDF file *again I'm asking for two different projects
