Virtual and augmented reality have changed the way people learn, play, and work. These technologies have made a big impact on how people interact with their surroundings. However, there is still a lot to learn about how these technologies affect how people move and coordinate their actions. This study looked at how different types of screens and body positions influence how well people can use both hands together. It compared two types of screens: virtual reality (VR) goggles and a projected screen. The study also looked at how people performed while standing up and lying down.

The study included 12 people who all preferred using their right hand. They had to do a task that required them to use both hands together in a specific way. Their performance was measured using special graphs that showed how well they could coordinate their movements. The results showed that using VR goggles made it easier for people to perform the task well, no matter if they were standing or lying down. This suggests that VR goggles help people focus better by reducing distractions and making it easier to ignore changes in their environment. On the other hand, the projected screen made it easier for people to synchronize their movements when they were lying down, but not when they were standing up. This shows that the type of screen can affect how well people can coordinate their movements depending on their body position. The projected screen also led to fewer mistakes when people were lying down. This means that while VR goggles help people perform consistently in different positions, projected screens might be better for tasks that require precise control and focus.

The study shows that there is a trade-off between the two types of screens. VR goggles offer stability and adaptability, making them good for tasks that require consistent performance in different positions. Projected screens, however, might be better for tasks that need precise control and attention. This means that when designing training programs, rehabilitation exercises, or any task that involves motor coordination, it is important to consider the specific needs of the task and choose the right type of display.

The study also highlights the importance of understanding how different factors can affect motor performance. By knowing how display type and body position influence movement, researchers can develop better tools and techniques for improving motor skills. This knowledge can be applied in various fields, from education to healthcare, to help people perform better in different situations. It is also important to note that while this study provides valuable insights, more research is needed to fully understand the complex ways in which these factors interact.

The study also raises questions about the future of virtual and augmented reality. As these technologies continue to evolve, it will be important to consider how they can be used to improve motor performance and coordination. This includes not only the type of display but also the design of the tasks and the environment in which they are performed. By taking a critical look at these factors, researchers can develop more effective and efficient ways to use virtual and augmented reality for a wide range of applications.
