吳宜曄於作品中試著處理屬於個體間些微不同的知覺能力與情感狀態 ; 洞察事物的瞬間、訊息傳遞和解讀、觀看真實與虛擬幻象的交錯。透過研究媒材技術進而找出可被操作的某個關鍵與主題呼應 ; 如重組構成數位影像的像素、操作電子郵件的函式、多畫面影像的關係等。也嘗試以不同手法接近想談論的主題 ; 如單純的錄像、即時的影像、影像裝置與空間的關係、音效、文字、甚至網路。
For the longest time, I Yeh’s work has focused on the minute differences in emotion and observation between individuals, including themes such as first impressions, the sending and receiving of messages, and the blurred lines between experiencing the real and virtual. By studying the mediums of technology he find malleable metaphorical points to harken back to the themes. Such as, reconstructing the pixel of live image, manipulating the function of e-mail system, and the relationship between multi-channel images. he approach the subject and themes by means of single-channel video, instant image, video installation, sound effect, space, text, and even the internet.
