It should be noted that the bluetooth headset 100 according to the embodiment of the present invention has a Text-to-Speech (TTS) module 20, which is coupled to the beacon information receiving module 10 and can perform a Text-to-Speech (Text-to-Speech) function, so that the shopping information in the Text format output by the beacon information receiving module 10 can be converted into a Speech format and then output as an audio signal. Next, when the user wears the bluetooth headset 100 and enters the signal area created by the second beacon device 200b, the text-to-speech module 20 of the bluetooth headset 100 can convert the catering information analyzed and output by the beacon information receiving module 10 in the text format into the speech format, and then output the converted catering information as an audio signal. Finally, when the user wears the bluetooth headset 100 and enters the signal area created by the third beacon device 200c, the text-to-speech module 10 of the bluetooth headset 100 can convert the activity information analyzed and output by the beacon information receiving module 10 in the text format into the speech format, and then output the activity information in the audio signal.
Therefore, when a user wears the bluetooth headset 100 according to the embodiment of the present invention to visit a shopping mall, the bluetooth headset 100 can receive beacon information and has a text-to-speech function, and can convert the received and analyzed shopping information, dining information, or activity information in a text format into a speech format and output the speech format as an audio signal, so that the user can receive an auditory notification through the bluetooth headset 100, and can concentrate on the current activity rather than a visual notification, and does not need to look down at the mobile phone, thereby providing a more immersive experience for the user.
Further, since the beacon device 200 does not substantially move, the beacon device 200 can be used as a beacon device for positioning, and can continuously broadcast position information of the location thereof, thereby providing guidance in the room. Therefore, in an application scenario of the embodiment of the present invention, a beacon device 200 may be disposed at each exit or near the exit of a large public place such as an airport or a station, when a user wears the bluetooth headset 100 according to the embodiment of the present invention to approach the exit, the location information in the text format may be converted into a voice format and output as an audio signal through the text-to-speech function of the bluetooth headset 100, and the location information may include the name of the exit or the name of the exit nearby, so that when the user moves forward in the airport or the station in a fast pace, the user does not need to look over the mobile phone with his head down, and the situation that the mobile phone is easy to look over with his head down when walking can be avoided.
In addition, in an application scenario of the embodiment of the present invention, a beacon device 200 may be placed under each of the paintings of the exhibition or gallery to continuously broadcast the navigation information of the paintings.
