多彩視覺誘發腦控顯示系統與影像補償技術之研究

Abstract

現今顯示系統與使用者的互動已經越來越普及，然而在顯示技術逐漸成熟的同時，如何再創造出更多顯示器未來的價值，更是重要的課題。 本計畫的研究目的便是在結合顯示技術提出一視覺腦機介面互動式顯示系統。視覺腦機介面為一經視覺刺激誘發腦電波變化，透過腦電波讓使用者可以直接對外界裝置與儀器進行控制的一種溝通與連結的管道。此技術的優勢在於以更直覺化的操作模式，並結合日益重要的腦科學研究領域，發展一具更為人性化的互動系統。 本計畫研究不同的色彩視覺刺激對大腦神經電位反應的變化，進而延伸至靜態、動態影像的視覺刺激，發展影像處理之技術，同時解決影像失真、色分離等問題，保持影像的完整性，如此方可使視覺腦機互動系統有更靈活的運用空間，亦為顯示器產業引入更智慧化的應用層面，為顯示器產業與視覺腦機互動系統的重要發展。

Nowadays, display system with user interaction has become increasingly popular in display technology. However, how to recreate more future values of displays is a significant issue at the same time when the display technology gradually becomes mature. The objective of this sub-project is to propose a visual-based SSVEP BCI interactive system integrated with display technology. The SSVEP BCI system is a communication and connection for users to control external devices or instruments with EEG evoked by visual stimuli. The intuitive operations of SSVEP BCI-based interactive displays is one of the most important advantages, and after combining with the increasingly important field of brain science, an user-friendly interactive system as a meaningful innovation can improve the quality of people’s lives. This project studies the effects of polychromatic visual stimuli on brain wave potential responses, and then extended to the visual stimulation of static and dynamic images, the development of image processing technology, while solving problems such as image distortion and color separation to maintain the integrity of the image. Therefore, the visual-based brain-computer interactive system will have more flexible application. Moreover, the display industry can be leaded to the level of smarter application, which is an important development of the display industry as well as the SSVEP BCI-based interactive displays.
