Hi,Kaining. I agree with you that there are many ways to show that multimedia and AR can work together. For example, augmented reality technology uses a device that can capture the visual effects of the real world. People can view animation, sound and data through the screen in the image. I also learned about the development of augmented reality technology in the future. I think there can be more intelligent input recognition in the future, such as odor recognition, voice recognition and gesture recognition.In the future, the development of reality technology must be more advanced than augmented reality technology.I learned the characteristics of instructional design from your blog. Let me know that instructional design is a learner centered process that helps promote learning more effectively.
