Coordinate alignment using acceleration data from a smartphone to interact with a Digital TV

Abstract

Using and holding a smartphone has become natural and ensures user acceptance as well as intuitive handling. We focus on using accelerators in a smartphone to interact with a Digital TV. To use the orientation and movement of smartphones for use interaction, the coordinate alignment between a smartphone and the screen of a Digital TV is required. In this paper, we proposed the method that allows aligning the coordinate extracted from acceleration data to the screen coordinate or world coordinate of a Digital TV. From experimental results, our proposed method has a good performance in a coordinate alignment.
