Today people can use the phone to talk with others almost anywhere on the earth . But when you use the phone , you don?t see the person you are talking with . That may change in the near future .

　　Today some people are using a kind of telephone called the picture phone or vision phone . With it , two people who are talking can see each other .

　　Picture phones can be useful when you have something to show the person you?re calling . They may have other uses in the future . One day you may be able to ring up a library and ask to see a book.

　　Then you?ll be able to read the book right over your picture phone . Or you may be able to go shopping through your picture phone . If you see something in the newspaper that you think you want to buy , you?ll go to your phone and call the shop . People at the shop will show you the thing you?re interested in right over the phone . You?ll be able to shop all over town and never even leave your room !
