Systems, methods, and non-transitory computer readable media containing instructions for causing at least one processor to perform operations for changing display of virtual content based on temperature are provided. In one implementation, the processor is configured to perform operations comprising displaying virtual content via a wearable extended reality appliance, wherein during displaying of the virtual content, heat is generated by at least one component of the wearable extended reality appliance; receiving information indicative of a temperature associated with the wearable extended reality appliance; determining a need to change display settings of the virtual content based on the received information; and based on the determination, changing the display settings of the virtual content to achieve a target temperature.

A luminous keyboard and an optical module thereof are provided. The optical module includes a light guide sheet, a reflective film on one side of the light guide sheet, and an optical film on another side of the light guide sheet opposite to the reflective film. The optical film has a mask pattern. The mask pattern defines a light-transparent region, a light-shielding region, and a light modulation region extending from the light-shielding region to the light-transparent region. The light-transparent region allows light to pass therethrough. The light-shielding region blocks light. The light modulation region partially allows light to pass therethrough and partially blocks light, so that an average light-transmitting rate per unit area of the light modulation region is smaller than that of the light-transparent region and larger than that of the light-shielding region.
