A method for deleting messages, comprising:

• step A01:
• recording a sliding path of a user on a terminal and mapping the sliding path as a message deleting command;
• step A02:
• defining a margin of error based on the sliding path;
• step A:
• popping up a message prompt box when a new message is detected and must be displayed, whether the screen is locked or the terminal is being used;
• step B:
• examining the sliding path of users on the screen and deciding whether it is in line with the pre-defined deleting path;
• and
• step C:
• deleting the message directly when the sliding path is in line with the pre-defined deleting path,
• wherein the shape of the sliding path comprises square, circle and line, which comprises straight lines, tilted lines and curved lines;
• defining the margin of error comprises defining the direction, length, and position on the screen of a linear sliding path, and the size and position on the screen of a square/circle sliding path,
• wherein the margin of error comprises a length L of the actual sliding path, with L meeting the criteria L1≤L≤L2;
• a height H, with H meeting the criteria H1≤H≤H2, where L1 is a first length, L2 is a second length, H1 is a first height and H2 is a second height.
