Abstract: Augmented Reality (AR) can make cultural heritage easier to explore by placing digital information and three-dimensional (3D) reconstructions into a user's view of the real world. It can support museum interpretation, tourism, education, and the documentation of historical objects. However, an engaging AR experience is not enough on its own to preserve heritage. A useful system also needs reliable historical information, access for people using different devices and network conditions, and a plan for keeping digital records available over time. This paper reviews four selected studies supplied for the review: an AR software adaptor for smart glasses, an interactive globe for tourism, an AR exhibition of traditional Chinese watermeasurement instruments, and the WebAR-based ARcheoTech platform for Indian heritage. Three wider review papers are also considered to place these examples in context. The studies show different ways to develop and deliver AR experiences, but they use different application settings and evaluation approaches, so their results cannot be compared as if they came from one experiment. Based on this focused review, the paper identifies research opportunities in source-linked historical narratives, community review of cultural information, lowbandwidth access, digital provenance, and long-term preservation. It proposes a conceptual framework called HeritageAR India that combines WebAR, structured heritage records, source and contributor information, optimized 3D assets, and preservation-oriented archiving. The framework is a proposal for future development; it has not been implemented or experimentally evaluated in this paper.
