Information processing device for selecting notification to prompt safety action performed by user in accordance with user behavior
Provided is an information processing device including a control unit that: stores a plurality of first notifications for prompting a safety action in association with the safety action to be taken by a user; selects one first notification from among the plurality of the first notifications when a determination is made to prompt the user to take the safety action in accordance with a behavior of the user; and outputs a presentation instruction for the selected one first notification.
1. A wearable terminal device comprising:
a sensor module configured to acquire a behavior of a user holding the wearable terminal device;
an output device configured to play a voice massage;
one or more memories configured to store a notification database and an action history database of the user, the notification database including a plurality of first notifications for prompting a safety action to be taken by the user, the plurality of first notifications including four voice messages with four different voices and a same message, the four different voices being a male synthetic voice, a female synthetic voice, a character voice and a recorded voice; and
one or more processors, wherein the one or more processors are programmed to:
select one voice message from among the plurality of the first notifications to prompt the user to take the safety action in accordance with the behavior of the user acquired by the sensor module;
cause the output device to play the selected one voice message;
determine whether the user has taken the safety action after the output device playing the selected one voice message;
add information indicating the one voice message and information indicating a result of the determination to the action history database each time the determination is made; and
select the one voice massage based on the action history database, wherein the one or more processors are further programmed to;
calculate a probability that the user has taken the safety action after causing the output device to play each of the four voice messages, based on the action history database;
select one voice message with the highest probability of the user taking the safety action when selecting the one voice massage from among the plurality of the first notifications; and
cause the output device to play the selected one voice message with the highest probability of the user taking the safety action.
2. A wearable terminal device comprising:
a sensor module configured to acquire a behavior of a user holding the wearable terminal device;
an output device configured to play a voice massage;
one or more memories configured to store a notification database and an action history database of the user, the notification database including a plurality of first notifications for prompting a safety action to be taken by the user, the plurality of first notifications including four voice messages with four different voices and a same message, and the four different voices being a male synthetic voice, a female synthetic voice, a character voice and a recorded voice; and
one or more processors, wherein the one or more processors are programmed to:
select one voice message from among the plurality of the first notifications to prompt the user to take the safety action in accordance with the behavior of the user acquired by the sensor module;
cause the output device to play the selected one voice message:
determine whether the user has taken the safety action after the output device playing the selected one voice message;
add information indicating the one voice message and information indicating a result of the determination to the action history database each time the determination is made; and
select the one voice massage based on the action history database, wherein
calculate a probability that the user has taken the safety action after causing the output device to play each of the four voice messages, based on the action history database;
classify each of the four voice messages into one of a first group in which the probability is equal to or greater than a threshold value and a second group in which the probability is less than the threshold value; and
set a first selection rate that is a probability that the one voice message is selected from the first group to be higher than a second selection rate that is a probability that the one voice message is selected from the second group, when selecting the one voice message from among the plurality of the first notifications.
3. The wearable terminal device according to claim 1 , wherein:
the one or more memories are further configured to store a plurality of second notifications different from the plurality of the first notifications; and
the one or more processors are further programmed to:
select one second notification from among the plurality of the second notifications after the determination; and
output a presentation instruction for the selected one second notification.
4. The wearable terminal device according to claim 3 , wherein the one or more processors are further programmed to:
add the information indicating the one voice message, the information indicating the result of the determination, and information indicating the second notification presented after the determination to the action history database each time the determination is made; and
select the one second notification based on the action history database when selecting the one second notification from among the plurality of the second notifications.
