Haptic feedback is crucial for enhancing realism and immersion in XR applications, yet current implementations often lack consistency across devices and interaction types. In this paper, we propose a universal approach for designing real-time haptic feedback in the Meta Quest ecosystem, based on a modular architecture and an interaction- driven rule. Our key insight is that the timing of haptic feedback should depend on the semantics of interaction: feedback should be triggered upon physical contact if the object does not change its state, and upon state change otherwise. We implemented this principle in Unity using a layered architecture that decouples hand logic, application logic, and glove-specific hardware control. The framework supports both custom-built (Haptic CeTI Glove) and commercial (TactGlove DK2) gloves and has been validated in two XR applications: a juggling simulator and a latency testing interface. Our results demonstrate how architecture- level abstraction enables reusability and extensibility across use cases, while user testing highlights the importance of latency in perceived realism. The proposed rule provides a practical guideline for developers aiming to design intuitive and consistent haptic experiences in XR.
