Action Through Non Action is a video performance where the artist uses his body as an interfering sensor to capture the rhythm caused by its presence in a crowd. The performer stands still in the middle of a crowd in the most densely populated district in Hong Kong. The artist performs no action, even so interaction cannot be avoided, his presence creates an interference in the normal flow of the crowd.

The individuals change their paths, the presence of the performer originates multiple chain reactions. The touches of the elements of the crowd in the performer’s both arms are recorded through the use of several contact microphones connected to a recorder and a headphone set. The headphones isolate the performer’s audition, he can only listen to the sound of people touching him. The encrypted data originates a score that interferes with the video playback by controlling an optical flow algorithm. The video presented in the performance interference in its own documentation.

Action Through Non Action 是一段視像表演。藝術家João Vasco Paiva以他的身體作感應器，來捕捉他在人群之中所產生的旋律。

只見藝術家身處香港最擁擠的地段的人群之中:他並無動作。即便如此，他與人群的互 動仍在所難免。他的存在已產生干擾，擾亂了人潮本身的移動。藝術家如連鎖反應的源 頭，人群因他而改變原來的路線。當人們與他相觸碰之時，觸碰就由安裝在藝術家雙臂的感應器所紀錄，並同時傳送到錄音儀器及藝術家所戴的耳機內。由於耳機有隔音功效，在表演過程中藝術家就只能聽到因別人觸碰他而起的聲音。另一方面，加密過的錄音則按一套以光流而定的計算法來干擾錄像重播。這錄像是表演本身及其干擾過程作出的表演記錄。
