The document discusses biosyncing, which is defined as bio-mechanical symbiosis between a human and machine in a reactive, performance-augmenting loop. It provides examples of communication in biosyncing including biometric data, feedback adjustment, and nudges. Recent developments in supporting technologies like artificial intelligence and mixed reality are advancing and improving biosyncing. The document discusses several prototypes created by Pearson Labs involving biosyncing, mixed reality, and their application in education. It addresses hurdles and opportunities for using these technologies in education.
