The ability to emphasize specific words or phrases on Android devices by rendering them in a heavier font weight is a common requirement across various applications. For example, in a messaging app, displaying the sender’s name in a prominent typeface assists in quickly identifying who sent a particular message.
Emphasis through typeface modification serves several purposes. It improves readability by creating visual cues for the reader, highlighting key information. A heavier font weight can also signal importance, drawing the user’s attention to crucial aspects of the text. Historically, physical typewriters lacked this function. The digital revolution introduced these capabilities, significantly improving document presentation.
