We propose a remote transmission system of hand clapping from the audience to the performer on live video streaming. This system consists of a collection system for a clapping button and hand clapping machines. The collection system for these buttons is to count the number of clicks they receive on the related website. The hand clapping machine is a mechanical device that imitates hand clapping and works by increasing the number of the clicks to produce a clapping sound and the physical movements of hands at the shooting location. This system is intended to reproduce the simple presence of the audience at the shooting location by transmitting movement and sound of hand clapping in real-time. We consider and evaluate this system by observing the behavior and the evaluation of the performer and audience at performances where this system is used.
