The National Science Foundation (NSF) is offering a grant opportunity titled "Mind, Machine and Motor Nexus" (M3X) aimed at supporting fundamental research that enhances bidirectional interactions between intelligent engineered systems and humans within physics-based environments. This program seeks proposals that advance knowledge in areas such as conceptual frameworks, dynamic interaction analysis, and innovative technologies for enhanced interaction, particularly in complex settings like elder care and disaster response. The M3X program emphasizes the importance of understanding human-machine collaboration and encourages submissions that propose significant contributions to the field. Proposals can be submitted at any time, and interested applicants can seek feedback on their project summaries by contacting M3X@nsf.gov.
