In the sphere of metaverse, human–computer interaction (HCI) technology and its allied intellectual machine algorithms have fascinating scope of exploration. Intelligent robots are highly used in medical, smart homes, wearable technology, intelligent tutoring, mobile-based learning, privacy, and security domain. HCI refers to the process by which a computer and a person exchange information in a particular way to complete particular tasks. Additionally, a lot of technological companies, including Facebook and Microsoft, have initiated to build metaverse, an alive environment with a new social arrangement. As a result, its future is uncertain. This research work presents complete and comprehensive processing techniques for metaverse and HCI. It also analyzes and confers the features and constraints associated with these methods for compacting visual data, interacting methods, assessment and evaluation method, and assisted living for the better quality of life while dealing with HCI technology. The work examines the use of the concepts of metaverse and HCI and briefly covers their fundamental ideas. This study also tried to include the challenges that arise fundamentally. The chapter also includes the arena that is beyond HCI and metaverse. The metaverse is a promising sector with tremendous expansion possibilities, but there are still several pressing challenges, this paper will argue, drawing on a number of articles and reports from recent years.
