You’re right that traditional QR codes require a camera to scan, which can be a challenge in virtual reality (VR) environments where users are wearing head-mounted displays. However, there are still a few ways that QR codes can be used in VR.
One option is to use motion controllers to scan QR codes. For example, if a user is playing a VR game and encounters a QR code, they could point their motion controller at the code and “scan” it by pressing a button. This would trigger an action or experience within the game.
Another option is to use a separate device, such as a smartphone or tablet, to scan QR codes. For example, a VR experience could prompt the user to take off their headset and scan a QR code using their phone. This would allow the user to access additional content or information related to the VR experience.
In addition to QR codes, there are other ways to provide interactive and clickable elements within VR environments. For example, objects within the environment could be designed to respond to user input, such as hovering over an object with a motion controller to trigger an action or display information.
Another option is to use gaze-based interactions, where the user’s gaze is used to trigger actions or display information. For example, the user could look at an object in the VR environment to access additional information or trigger a related experience.
Overall, while scanning QR codes directly in VR environments can be challenging, there are still ways to incorporate QR codes and interactive elements within these experiences. As VR technology continues to evolve, we may see new and innovative ways to incorporate interactive elements and clickable links within VR environments
