Abstract

The participant terminal 80 includes imaging means 81 for shooting video of the participant who uses the participant terminal 80 , frequency measurement means 82 for measuring the number of nods of the participant from the shot video, and action information transmission means 83 for transmitting action information that information of the participant is associated with the number of nods to the server 70 . The server 70 includes transmission means 71 for transmitting the action information to the speaker terminal 90 . The speaker terminal 90 includes participant output means 91 for outputting the information of the participant in order according to the number of nods included in the action information.

Claims (43)

1 . A communication system comprising:

participant terminals used by participants of a lecture or conference;

a speaker terminal used by a speaker of the lecture or conference; and

a server,

wherein the participant terminal includes:

imaging means for shooting video of the participant who uses the participant terminal;

frequency measurement means for measuring the number of nods of the participant from the shot video; and

action information transmission means for transmitting action information that information of the participant is associated with the number of nods to the server,

wherein the server includes transmission means for transmitting the action information to the speaker terminal,

wherein the speaker terminal includes participant output means for outputting the information of the participant in order according to the number of nods included in the action information and measurement start instruction means for instructing to start measuring actions of the participant,

wherein the measurement start instruction means transmits an instruction to start measuring the number of nods of the participant to the server,

wherein the transmission means in the server transmits an instruction to start measuring the number of nods of the participant to the participant terminal, and

wherein the frequency measurement means starts measuring the number of nods when receiving the instruction to start measuring.

2 . The communication system according to claim 1 , wherein

the speaker terminal includes initialization instruction means for instructing to initialize the number of actions of the participant,

the initialization instruction means instructs to the server to initialize the number of nods of the participant,

the transmission means in the server transmits an initialization instruction for the number of nods of the participant to the participant terminal, and

the frequency measurement means initializes the number of nods of the participant when receiving the initialization instruction.

3 . The communication system according to claim 1 ,

wherein the participant output means outputs the information of the participant in descending or ascending order of the number of nods.

4 . The communication system according to claim 1 , wherein

the frequency measurement means measures the number of claps of the participant from accepted input video,

the action information transmission means transmits the action information that the information of the participant is associated with the number of claps to the server,

the transmission means in the server transmits the action information to the speaker terminal, and

the participant output means in the speaker terminal outputs the information of the participant in order according to the number of claps included in the action information.

5 . The communication system according to claim 1 , wherein

the server includes participant number measurement means for measuring the number of detected participants that is the number of terminals which transmit the action information including one or more nods numbers,

the transmission means in the server transmits the number of detected participants to the speaker terminal, and

the participant output means outputs the number of detected participants.

6 . An output device comprising:

a memory storing instructions; and

one or more processors configured to execute the instructions to:

transmit an instruction to start measuring the number of nods of the participant to the server which transmits an instruction to start measuring the number of nods of the participant to the participant terminal which measures the number of nods when receiving the instruction to start measuring;

input for each participant the number of nods of the participant measured from shot video of the participant; and

output information of the participant in order according to the number of nods.

7 . A communication method performed by a participant terminal used by a participant of a lecture or conference, a server, and a speaker terminal used by a speaker of the lecture or conference, the method comprising:

the speaker terminal sends an instruction to start measuring the number of nods of the participant to the server,

the server transmits an instruction to start measuring the number of nods of the participant to the participant terminal,

the participant terminal shoots video of the participant who uses the participant terminal,

the participant terminal measures the number of nods of the participant from the shot video, wherein the participant terminal starts measuring the number of nods when receiving the instruction to start measuring,

the participant terminal transmits action information that information of the participant is associated with the number of nods to the server,

the server transmits the action information to the speaker terminal, and

the speaker terminal outputs the information of the participant in order according to the number of nods included in the action information.
