Lo-Fi（低傳真），與高傳真相對應，即表示「相當低的資訊傳真度」。數位時代剛起步之初的數位產品，由於電子處理的速度及能力有限，並不如今日高傳真科技的傳真度。在高解析度下，這些高端產品，幾乎無法察覺數位與類比之間的差異。然而低解析度，所呈現的是一種抽象與失真的感覺。

相信不少人對過去幾個像素（pixel）所組成的電子遊戲角色，充滿了想像。這些資訊雖不盡寫實，但卻因為其相當低度的資訊量傳達，以及其單純化，反而凸顯了所要傳達的資訊強度。這種限促狀況所設計出的圖形、聲響，也因此都是被精心考慮過的。

「Lo – Fi」，以伺服馬達矩陣，控制高數量的鋁箔片反光，加上投射燈光的渲染…形成一具類比的顯示螢幕。觀眾的視野角度，直接影響到所觀看出的內容，形成在數位與類比之間的交錯感覺。

Lo-Fi ("low fidelity"), contrasting with high fidelity, contains "rather low quantity of information in definition."

Unlike today's high-end products that barely exhibited the distinction between digital and analog processes, early electronic products at the infancy of the digital age had a distinct "digital" feel due to limited capabilities and speed in expressing information precisely. As a result, they seemed to present an abstract and distorted form of low-definition information.

Avatars composed of few pixels in video games of the 70s must have fascinated and inspired many players. Although the figures lack life-like details, the simplification as conveyed by the low information flow surprisingly accentuates the strength of that information. Under these constraints, the figures, images, and sounds have been elaborately designed.

"Lo-Fi" uses a matrix of servo motors to control high-volume reflections of aluminum foils under a projected light, hence creating a display similar to an analog LED monitor. The audience's viewing angle can directly alter the information they may receive, arousing in them an ambiguous perception, alternating between the digital and the analog.
