Systems and methods for verifying participation in a meeting using sound signals
Systems and methods for verifying the presence of an attendee in an education session include providing, by a computer hardware processor, information for a codified sound to a leader of the education session, where the leader is located in a substantially enclosed space in which the education session is held. The codified sound represents a leader code. The codified sound is emitted from a first device associated with the leader. A sound signal is received by a second device associated with the attendee. An attendee code is determined from the sound signal received by the second device. The system, such as using the computer hardware processor or the second device, determines whether the attendee code matches the leader code.
1. A method of verifying presence of an attendee at an education session, the method comprising:
providing, by a computer hardware processor, information for a codified sound to a leader of the education session, wherein the leader is located in a substantially enclosed space in which the education session is held, and wherein the codified sound represents a leader code;
emitting the codified sound from a first device associated with the leader;
receiving a sound signal, by a second device associated with the attendee;
determining, by the second device, an attendee code from the sound signal received by the second device; and
determining whether the attendee code matches the leader code.
2. The method of claim 1 , wherein the codified sound is a human-inaudible acoustic signal.
3. The method of claim 1 , wherein the codified sound has a frequency above 20 kHz or less than 20 Hz.
4. The method of claim 1 , further comprising emitting a notification sound having an audible frequency, prior to or while emitting the codified sound.
5. The method of claim 1 , wherein the emitting comprises altering the codified sound during the education session.
6. The method of claim 1 , wherein the codified sound includes a modulated code.
7. The method of claim 6 , wherein the determining of the attendee code comprises demodulating numerical values associated with frequencies in the sound signal.
8. The method of claim 1 , further comprising notifying the leader that the attendee is present within the substantially enclosed space when the attendee code matches the leader code.
9. The method of claim 1 , further comprising notifying the leader that the attendee is not present within the substantially enclosed space when the attendee code does not match the leader code or when the attendee code is not received in a permitted period of time.
10. The method of claim 1 , further comprising allowing the attendee to receive content for the education session after the attendee code is verified to match the leader code, wherein the content is sent to the attendee without use of any codified sound signals.
11. The method of claim 1 , wherein the providing and the sending are performed via an internet connection or a cellular network.
12. The method of claim 1 , wherein the substantially enclosed space is bounded by physical barriers, wherein the physical barriers deter the codified sound from being emitted beyond the substantially enclosed space.
13. The method of claim 1 , wherein the emitting comprises adjusting a volume of the codified sound according to a size of the substantially enclosed space.
14. The method of claim 1 , wherein the emitting comprises using an auxiliary speaker with the first device, to adjust a distance range of the codified sound according to a configuration of the substantially enclosed space.
