This submission discusses my research interests in two areas: measuring user satisfaction in goal-oriented dialogue systems and exploring the potential of multi-modal interactions. For goal-oriented dialogue systems, I focus on evaluating and enhancing user satisfaction throughout the interaction process, aiming to propose innovative strategies and address the limitations of existing evaluation techniques. Additionally, I explore the benefits of multi-modal dialogue systems, highlighting their ability to provide more natural and immersive conversations by incorporating various communication modes such as speech, text, gestures, and visuals.
