Purpose: This paper aims to describe digital twin and EPI Cube impacts on users’ perceptionMethodology: This is a literature review. Literature was searched in Science Direct and Google Scholar databases. Keywords were augmented reality, virtual reality, digital twin, EPI Cube, users’ perception. Inclusion criteria are review and research paper. Exclusion criteria are short note or commentary.Results: The invention of Augmented-Reality, Virtual-Reality, and Mixed-Reality technologies gives a new perception for users. There are integrations of virtual and physical objects. The most common terms are EPI Cube and digital twin. EPI Cube means Embodiment, Presence, and Interactivity. Embodiment is associated with technological application and integration. Digital twin is other term for augmented reality and virtual reality. The boundaries between those areas are not clear enough. However, the important thing is the user’s perception.  It is essential in business aspects because there is a sensation of interaction in mixed reality.Conclusion: Digital twin and EPI Cube give a sensation of interaction in mixed reality between virtual and augmented reality. Limitations: This is a narrative review, therefore it cannot provide any empirical data about the digital twin and EPI Cube impacts on users’ perception.Contribution: Augmented and virtual reality, also digital twin and EPI Cube are useful in business application. They give new impacts and perceptions for users. It is suitable for business application.Keywords: augmented reality, digital twin, EPI Cube, user’s perception, virtual reality
