Question: We are trying to invent a service which is called VR(virtual reality) online shopping. It is basically that we are able to shop online and understand this product through VR techniques. For example, if I'm trying to buy a table online, through the VR techniques, I can know the size and interior and exterior of the table, and I can clearly know that if the table fit in my room or not. This is just a example, it could be any other products. Please write this service's market trend in about 400 words.
