User interactive apparatus and method, and computer program utilizing a direction detector with an electromagnetic transmitter for detecting viewing direction of a user wearing the transmitter

摘要

A response storage unit stores a response, a watching degree relative to a display unit, and an output form of the response to a speaker and the display unit. An extracting unit extracts a request from a speech recognition result. A response determining unit determines a response based on the extracted request. A direction detector detects a viewing direction based on sensing information received from a transmitter mounted on a user. A watching-degree determining unit determines a watching degree based on the viewing direction. An output controller obtains an output form corresponding to the response and the determined watching degree from the response storage unit, and outputs the response to the speaker and the display unit according to the obtained output form.
