Imagine shopping using a virtual shopping mall on the Web via your computer, smartphone, or TV, where the products you order are really coming from a dull looking warehouse that lacks all the gloss and decorum of the virtual shopping mall.
Taking this further into the future, my guess is this 3D interface to online shopping could be woven into 3D games. If generation Web are use to gaming, then they could shop while inside a game or virtual world. The creation of Avatar Shopping could also be a useful service. That is, an online profile that could be embedded into many services including websites, apps. and games.
