The XR stack is the set of technologies, components, platforms, and applications that is needed to offer XR/immersive experiences. A key development is the competition between big tech companies (Apple, Meta, Microsoft, and Google) – which is a repeating pattern – to create complete and leading XR stacks with associated ecosystems.
Control over head-mounted display hardware, operating systems, (AI-based) XR engines, middleware, and the adoption of virtual assistants is central to gaining a competitive edge in the XR market.
Big tech companies are progressing substantially on their XR stack control as they look at their portfolios of technologies, products, services, and partnerships. On the contrary, these same big tech companies are also participating in standardisation bodies and open XR initiatives.
