Virtual reality head-mounted displays (VR HMDs) can provide three-dimensional content to increase user immersion that is relatively acceptable. However, user interactions with VR HMDs often do not satisfy a virtual environment. In this article, the authors propose a smart human–computer interaction technique that runs on VR HMDs and Leap Motion. In this study, they focused on improving interaction methods for VR content and providing interfaces and information necessary for the operation of such content in a user-friendly manner, which should reduce fatigue and dizziness. To this end, they propose and validate a smart head-up display that is suitable for VR content. Specifically, a virtual head-up display (HUD) was designed and optimized for use with VR HMD and Leap Motion technologies. Additionally, they present comparative performance tests to validate the proposed system.
