Whether it's getting a wedding dress, makeup or a haircut, more shops are using tablet computers to help customers visualize what they would look like before actually taking the plunge.

One dress rental company centered in eastern Japan has been using an application it developed to let customers "try on" various wedding dresses.

After a photo of the customer's face is captured on the tablet screen, a hundred different dresses can be called up in succession. Even the color can be adjusted to match the bride-to-be's skin tone.
