Abstract

In human-robot interaction (HRI), the quality of user experience is paramount. Thus, developing strategies to tailor robotic responsiveness to user comfort zone is essential. However, current methods remain constrained by complex software and limited to unidirectional speed enhancement. Inspired by the adaptive pathways of biological brain, this study introduces a photochromic diarylethene-doped organic floating-gate field-effect transistor (OFGFET) capable of bidirectional response speed control. Mechanism investigations revealed that a light-controllable back charge transfer process facilitates dynamic speed adjustments. Notably, the OFGFET device potentially enables effective regulation of response speeds to enhance user comfort while maintaining efficient and detailed movie playback. This work establishes a distinctive paradigm in HRI, offering unprecedented adaptability that could transform user experience design across diverse interactive technologies.
