While virtual reality (VR) games offer immersive experiences, prolonged improper head posture during VR gaming sessions can cause neck discomfort and injuries. To address this issue, we prototyped a framework to detect instances of improper head posture and apply various visual interventions to correct them. After assessing the prototype's usability in a co-design workshop with participants experienced in VR design and kinesiology, we refined the interventions in two main directions --- using explicit visual indicators or employing implicit background changes. The refined interventions were subsequently tested in a controlled experiment involving a target selection task. The study results demonstrate that the interventions effectively helped participants maintain better head posture during VR gameplay compared to the control condition.
