Next, the control section 102 monitors whether or not a slide image turning operation has been performed (Step SB8). When the slide image turning operation has not been performed (NO at Step SB8), the control section 102 monitors again whether or not the identification information has been transmitted from the audience terminal 200 at Step SB3. When the slide image turning operation has been performed (YES at Step SB8), the control section 102 judges whether or not all slide images has been displayed (Step SB9). When all slide images has not been displayed (NO at Step SB9), the control section 102 reads out a next slide image at Step SB1 and performs the following process described above.
Therefore, the presenter can perform the presentation while watching the slide image and the question table T10 displayed on the display 107. When the identification information has been received from the audience terminal 200, the presenter can comprehend immediately a status of the questions by updating the total number of the identification information displayed on the question table T10 on a real-time basis. As a result, the presenter can give a follow up explanation for a slide image which has many questions and adjust allocation of time in the question-and-answer session according to the total number of the questions. In this manner, the presenter can make adaptable correspondence for the question-and-answer session during the presentation.
When all slide images has been displayed (YES at Step SB9), the control section 102 performs the question-and-answer session. Namely, the control section 102 reads out and display the slide image sequentially in order of the number of the identification information for the each slide image counted at Step SB5 (Step SB10). As the question table T10 described in
The control section 102 retransmits the slide image read out for the question-and-answer session to the audience terminal 200 (Step SB11). The audience can look the slide image corresponding to the questions by the audience terminal 200. Then, the control section 102 redisplays the previously displayed slide image sequentially in order of the number of the received identification information in response to a slide image turning operation by the presenter in the question-and-answer session (NO at Step SB12). When all slide images received the identification information has been redisplayed (YES at Step SB12), the presentation including the question-and-answer session ends.
As described above, the presenter can perform adaptable the question-and-answer session based on a status of the questions displayed and updated on the question table T10 in a real-time basis. The presenter can slide the question-and-answer session at an appropriate timing in consideration of a progress status and remaining time of the presentation. Thus, the presentation system according to the embodiment can provide a question-and-answer session that meets an audience need.
