Method and apparatus for detecting a force

A method for detecting a force, comprising:

• determining, according to a fitting function, a force corresponding to detected raw data when an input medium of a second electronic device is subjected to an acting force;
• wherein the fitting function is obtained by:
• acquiring a plurality of sample data of a first electronic device, wherein each of the plurality of sample data of the first electronic device comprises a preset force of the first electronic device and raw data of the first electronic device, and the raw data of the first electronic device is obtained by detecting a deformation signal generated by the preset force of the first electronic device applied to an input medium of the first electronic device;
• and
• determining the fitting function according to the plurality of sample data of the first electronic device, wherein the fitting function denotes a corresponding relationship between a force applied to the input medium of the first electronic device and the detected raw data;
• wherein the force corresponding to the detected raw data when the input medium of the second electronic device is subjected to the acting force is determined by a fourth raw data, a fourth force corresponding to the fourth raw data, a fifth raw data and a fifth force corresponding to the fifth raw data, wherein the fourth raw data is raw data greater than the first raw data in a data corresponding relationship table, and the fifth raw data is raw data smaller than the first raw data in the data corresponding relationship table, and the data corresponding relationship table comprises a corresponding relationship between different raw data and forces calculated in advance according to the fitting function.
