Information display system and information display method

Abstract

An information display system according to the present disclosure includes: display device provided in a mask, the display device being configured to display a screen viewed by a person wearing the mask; and display control unit for switching a displaying mode of the screen.

1 . A wearable device comprising:
 a sensor to detect environmental information;   at least one memory storing instructions; and   at least one processor configured to execute the instructions to:
 acquire the environmental information by the sensor; 
 display a first screen in front of the user, the first screen including an area to display the environmental information; and 
 display an alert on the first screen based on the environmental information sensed by the sensor. 
   
     
     
         2 . The wearable device according to  claim 1 , wherein the sensor is camera. 
     
     
         3 . The wearable device according to  claim 2 , wherein the environmental information includes video. 
     
     
         4 . The wearable device according to  claim 3 ,
 wherein the at least one processor further configured to execute the instructions to process an analyze for detecting a possibility of occurring an incident based on the video,   wherein the instructions to display the alert on the first screen is executed in the case of that information indicating specific feature is displayed in the video.   
     
     
         5 . The wearable device according to  claim 1 , wherein the sensor is gas sensor. 
     
     
         6 . The wearable device according to  claim 5 , wherein the environmental information includes a kinds of gas and concentration of the gas. 
     
     
         7 . The wearable device according to  claim 6 ,
 wherein the at least one processor further configured to execute the instructions to process an analyze for detecting a possibility of occurring an incident based on the kinds of gas and concentration of the gas,   wherein the instructions to display the alert on the first screen is executed in the case of that concentration of specific gas is greater than threshold.   
     
     
         8 . The wearable device according to  claim 1 , wherein the alert indicates detecting a possibility of occurring an incident. 
     
     
         9 . The wearable device according to  claim 1 ,
 wherein the at least one processor further configured to execute the instructions to receive an input to change screen to display in front of the user;   display a second screen in front of the user in response to receive the input, the second screen being different from the first screen.   
     
     
         10 . The wearable device according to  claim 9 ,
 wherein the at least one processor further configured to execute the instructions to display the alert on the second screen based on the environmental information sensed by the sensor,   wherein the alert for the second screen is displayed at specific position of the second screen, the specific position being different from a position of displaying the alert for the first screen.   
     
     
         11 . An information display method comprising:
 acquiring environmental information by a sensor to the detect environmental information;   displaying a first screen in front of the user, the first screen including an area to display the environmental information; and   displaying an alert on the first screen based on the environmental information sensed by the sensor.   
     
     
         12 . A non-transitory computer readable medium storing a program causing a computer to execute:
 acquiring environmental information by a sensor to the detect environmental information;   displaying a first screen in front of the user, the first screen including an area to display the environmental information; and   displaying an alert on the first screen based on the environmental information sensed by the sensor.
