For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Input method of the present invention and system, be applied to the electronic equipment with haptic signal generating unit.Described haptic signal can be the vibration signal of various frequency or intensity, also can be the signal that the sense of touch in the region that user is touched changes.Such as, when some haptic signals can make user touch corresponding region, feel smooth, when some haptic signals can make user touch corresponding region, feel coarse.Because different objects can give people different touch feelings, therefore by different haptic signals, can bring for user the touch feeling touching different objects.At present, market is proposed the multiple driver with haptic signal generating function (including, but not limited to motor, linear motor, piezoelectric ceramics, EAP, the sense of touch driver etc. that the intellectual materials such as EMP are made) and relevant control chip, the electronic equipment in the application can use related tactile driver and control chip as haptic signal generating unit.
Fig. 1 is the process flow diagram of input method embodiment 1 of the present invention.As shown in Figure 1, described method can comprise:
Step 101: produce haptic signal, so that user identifies according to the described haptic signal experienced by described haptic signal generating unit; Wherein, the field that different haptic signals is corresponding different;
The haptic signal that described haptic signal generating unit produces can be vibration signal, also can be other forms of haptic signal.For vibration signal, different haptic signals can have different vibration frequencies, time of vibration, and/or, oscillation intensity.The field that different haptic signals is corresponding different, different fields then can for different passwords.
Other forms of haptic signal comprises the true Haptic of senseg company.This technology can produce the electric field signal of frequency and Strength Changes on the surface of touch-screen., user, when touching this touch-screen, due to the effect of electric field, can experience the different texture impressions such as coarse or round and smooth.
User can carry out touch sensible by the limbs of self (such as palm) in the region that vibration signal sends.
Step 102: judge whether to receive the confirmation instruction, obtains the first judged result;
To be a vibration frequency the be vibration signal of 10 hertz supposing that the codon pair pre-set answers, and haptic signal generating unit produces is the vibration signal of 100 hertz, after then user senses this vibration, can determine that this vibration signal is not correct preset password.Now user can not input validation instruction.Haptic signal generating unit can continue the vibration signal producing other frequencies afterwards.
After user experiences the vibration signal of 10 hertz, user can input validation instruction.Concrete, can by the respective keys input validation instruction on electronic equipment.When electronic equipment is the electronic equipment with touch-screen, also input validation instruction can be carried out by the specific region touched on touch-screen.
Step 103: when described first judged result represent receive described confirmation instruction time, field corresponding for the described haptic signal produced in the time range between the first moment to the second moment when receiving described confirmation instruction before receiving described confirmation instruction is inputted.
Because haptic signal generating unit can produce multiple haptic signal according to preset rules (comprising random), in described multiple haptic signal, have plenty of the haptic signal of answering with codon pair, have plenty of the aliasing signal of not answering with codon pair.After user experiences the haptic signal of answering with codon pair, user understands input validation instruction, the haptic signal that produces in the time range between the first moment to the second moment when receiving described confirmation instruction before what now user confirmed receive described confirmation instruction just.Therefore, field corresponding for the described haptic signal produced in the time range between the first moment to the second moment when receiving described confirmation instruction before receiving described confirmation instruction can be inputted.
It should be noted that, receive the described haptic signal produced in the time range between the first moment to the second moment when receiving described confirmation instruction before described confirmation instruction, can be the haptic signal produced recently, also can be the continuous multiple haptic signal produced recently.Further, receive the field that the described haptic signal that produces in the time range between the first moment to the second moment when receiving described confirmation instruction before described confirmation instruction is corresponding, can be the shorter field that a haptic signal is corresponding, also can be the long field that multiple haptic signal is corresponding.
In the present embodiment, produce haptic signal, so that user identifies according to the described haptic signal experienced by haptic signal generating unit; When receiving the confirmation instruction, field corresponding for the described haptic signal produced in time range between the first moment to the second moment when receiving described confirmation instruction before receiving described confirmation instruction is inputted, the input function based on tactile feedback can be realized, owing to realizing input based on tactile feedback, the field of input cannot be in sight, so the situation adopting visual inputting interface to cause password to be revealed can be avoided, improve the security of input.
Fig. 2 is the process flow diagram of input method embodiment 2 of the present invention.As shown in Figure 2, described method can comprise:
Step 201: obtain oscillation intensity parameter, according to described oscillation intensity parameter, produce described vibration signal;
In this step, different codon pair answers the vibration signal of varying strength.Certainly, different time of vibration or vibration frequency also can be adopted to distinguish different vibration signals.
Step 202: judge whether to receive the confirmation instruction, obtains the first judged result;
Step 203: when described first judged result represent receive described confirmation instruction time, the described haptic signal produced recently is inputted as password.
Step 204: when described first judged result represent do not receive described confirmation instruction time, produce new haptic signal by described haptic signal generating unit, so that user identifies according to the described haptic signal experienced again.
When not receiving the confirmation instruction of user in Preset Time, just can judge that the first judged result is no.Input method in the present embodiment, can be one and generate (comprising random) process of various types of haptic signal according to preset rules.These haptic signals are corresponding password a bit, and some is not corresponding password.Therefore, when user does not have input validation instruction in Preset Time, can think that current haptic signal is not the haptic signal that codon pair is answered, therefore need to produce next haptic signal, so that user continues to judge whether to create correct password, thus completes the input process of password.
Fig. 3 is the process flow diagram of input method embodiment 3 of the present invention.As shown in Figure 3, described method can comprise:
Step 301: in the first predetermined time period, produces first group of haptic signal by described haptic signal generating unit;
In the present embodiment, in one group of haptic signal, both comprised the haptic signal as password, also comprising is not the haptic signal of password.Often organize haptic signal and comprise a haptic signal as password.Suppose that one group of haptic signal comprises three haptic signals altogether, so as first haptic signal that the haptic signal of password can be in one group of haptic signal, second haptic signal, or the 3rd haptic signal.
Step 302: judge whether to receive the confirmation instruction, obtains the first judged result;
User can input validation instruction at any time.That is, when one group of haptic signal not yet produces complete, if user has felt that then user can input validation instruction at once as the haptic signal of password.
Step 303: when described first judged result represent receive described confirmation instruction time, the described haptic signal produced recently is inputted as password.
Step 304: when receiving described first judged result in described first predetermined time period, and described first judged result represents when receiving described confirmation instruction, judges whether described first group of haptic signal produces complete, obtains the second judged result;
