Claim of US Patent No. 10,338,726

1. A method of distinguishing between different touch forces for a mobile device having a touch component, comprising steps of:(A) preloading an area of a maximum touch region of the touch component touched by a user's finger using at least one touch gesture with a maximum force, presetting a relationship among a current force, an area of a current touch region, the maximum force and the area of the maximum touch region, and presetting at least two force levels, wherein each of the at least two force levels corresponds to a respective range of a ratio of the current force to the maximum force, the relationship satisfies FNOW/FMAX)=(?SNOW/?SMAX), in which FNOW is the current force, FMAX is the maximum force, SNOW is the area of the current touch region, and SMAX is the area of the maximum touch region;
(C) detecting and calculating the area SNOW of the current touch region of the touch component when touched;
(D) according to the relationship, calculating the ratio FNOW/FMAX of the current force to the maximum force by using the area SNOW of the current touch region, so as to determine a corresponding one of the at least two force levels based on the calculated ratio FNOW/FMAX.
