A control method for a portable read-write pen, the portable read-write pen having a touch-read mode and a write-record mode, characterized in that, the portable read-write pen is controlled to automatically switch between the touch-read mode and the write-record mode based on a pressure state of a pen point of the portable read-write pen, and the pen point may be received in or protrude from a pen head, wherein the control method for a portable read-write pen comprises following steps:

• step S1 of detecting a state of the pen point of the portable read-write pen;
• and
• step S2 of controlling, according to the state of the pen point of the portable read-write pen, the portable read-write pen to enable the touch-read mode or the write-record mode,
• wherein detecting a state of the pen point of the portable read-write pen specifically comprises step S12 of:
• detecting a pressure state of the pen point of the portable read-write pen;
• and
• wherein controlling, according to the state of the pen point of the portable read-write pen, the portable read-write pen to enable the touch-read mode or the write-record mode specifically comprises step S22 of:
• determining whether a pressure on the pen point of the portable read-write pen is greater than a pre-set pressure threshold, wherein if yes, the portable read-write pen is controlled to enable the write-record mode;
• and if no, the portable read-write pen is controlled to enable the touch-read mode.
