3-D display and communication technology

In this paper, we describe 3-D display in the aspect of communication technology. 3-D display provides 3-D images to the viewers with more accurate and realistic information than which 2-D display does. This feature is an essential component of communication technology. Generally communication technology pursues for exchanging and sharing of thoughts, feelings and ideas. 3-D displays are effective contact media to achieve these goals. The concept of accessible spatial dimension of a person is used to describe 3-D display in the aspect of communication technology. It is classified into three dimensions and each of dimensions represents the dimension of contact media. Several research results, related with 3-D display and communication technology are introduced based on the concept.
