Capacitance plate can using current value as detection signal: when human body proximity capacitance plate, human body is equivalent to electric conductor, forms two electrodes of capacitor, according to capacitance calculation formula with the conductive layer in capacitance plate:
C=ε * ε 0*S/d ... formula 1
Wherein, C is capacitance, and S is that the right opposite of capacitor amasss, ε and ε 0 is the dielectric coefficient of two media forming electric capacity, and d is the distance between capacitor two electrodes.From formula 1, the distance between electric capacity C and two electrode is inversely proportional to, and when the hand of user is more close to screen, the strength of current of generation is larger; When distance d is identical, the area S of the hand of user is larger, and capacitance C is larger.Therefore, under utilizing range sensor to get the condition of staff and screen distance, strength of current can be utilized to detect the area of staff.
Under the normal operating conditions of capacitance plate, capacitance plate will be adjusted to and accurately identify user operation position, and only just make response to the complete contact screen of user's hand.In the present invention when user will unlock screen time, the induction standard of capacitance plate will be lowered, and then can current data be obtained, and the area S of the hand of analytical calculation user.Compared with the method for example one, example two does not rely on external light source, is therefore suitable for more extensive.

The characteristic two of fingerprint, i.e. " different ", proposed by British Henry 〃 Matthias Volz (Henry 〃 Fulds), namely write the author of " dactylography " for first.He is British royal fellow of the Faculty of Physicians and Surgeons, professor's biology.He is during Japan does missionary work, see that the file of much Japan is the same with the file of China, usually restrain impression of the hand, just start to collect fingerprint research in a large number, and the student of tissue Japan and doctor carry out the test of various relevant fingerprint, thus the fingerprint demonstrating different people is different.He also demonstrates the theory of " fingerprint is unchangeable " that Losec you (Welker) proposes simultaneously.
The method of example three based on fingerprint above-mentioned two large characteristics and propose.
The touch-screen of terminal is needed to have the function of fingerprint collecting in example three.Here fingerprint density refers to the number of streakline in unit area in the fingerprint of user, and unit is: bar/25mm
2.Can arrange and multi collect is carried out to the fingerprint of user, calculate corresponding fingerprint density respectively, the fingerprint density obtained by multi collect is again averaged, average, maximal value or minimum value to obtain final fingerprint density, exemplarily in three, the fingerprint density of the user determined.
