Adjusting font sizes

摘要

A device may determine a baseline size of a font, obtain a distance between a user and a mobile device when the baseline size is determined, determine, via a sensor, a current distance between the mobile device and the user, determine a target size of the font based on the current distance, the distance, and the baseline size, set a current size of the font to the target size of the font, and display, on the mobile device, characters in the font having the target size.

1. A device comprising:
an output component to provide an audio or visual output; a sensor to determine a distance between a user and the device; one or more processors to:
obtain, as a baseline distance between the user and the device, a particular distance between the user and the device via the sensor;provide test values for the audio or visual output to the user when the distance between the user and the device is the baseline distance;determine a baseline value based on a test value selected from the test values according to the baseline distance;after determining the baseline value, determine, via the sensor, a first current distance between the user and the device;determine a first target value for the audio or visual output based on the first current distance, the baseline distance, and the baseline value;provide, via the output component, an audio or visual output having a magnitude specified by the first target value;determine a second current distance between the user and the device;determine a second target value for the audio or visual output based on the second current distance, the baseline distance, and the baseline value; andprovide, via the output component, the audio or visual output, changing a magnitude of the audio or visual output toward a magnitude specified by the second target value at a speed that is dependent on a user-specified speed preference and a speed of a change from the first current distance to the second current distance; and a memory to store the determined baseline value, associating with the obtained baseline distance.
