  With the upcoming AI regulations (e.g., EU AI Act) and rapid advancements in
generative AI, new challenges emerge in the area of Human-Centered Responsible
Artificial Intelligence (HCR-AI). As AI becomes more ubiquitous, questions
around decision-making authority, human oversight, accountability,
sustainability, and the ethical and legal responsibilities of AI and their
creators become paramount. Addressing these questions requires a collaborative
approach. By involving stakeholders from various disciplines in the
2\textsuperscript{nd} edition of the HCR-AI Special Interest Group (SIG) at CHI
2024, we aim to discuss the implications of regulations in HCI research,
develop new theories, evaluation frameworks, and methods to navigate the
complex nature of AI ethics, steering AI development in a direction that is
beneficial and sustainable for all of humanity.
