For example, as shown in Figure 2 A, for a kind of possible embodiment of the present invention.In fig. 2, first operating body is The hand of user.Described image collecting unit is positioned at the described first operation body side surface, and so, described image collecting unit can Collect second image corresponding to described first image corresponding to first operating body and the first operating body shade. In fig. 2, shadeless hand is first operating body, and hypographous hand is the first operating body shade.In Fig. 2A In, the first position can be determined according to first operating body, and institute can be determined according to the first operating body shade State the second place, and in fig. 2 as can be seen that the first position and the second place do not overlap, and described first Put the distance with the second place in described first image information and be obviously more than first pre-determined distance, it is seen then that scheming First operating body described in 2A is in suspended state, and it does not touch the surface in the projection operation face.It is then if described First operating body is operated, and the electronic equipment can not respond to the operation.And it can be seen that in fig. 2 Camera is located at side, and so, from the perspective of camera, first operating body and the first operating body shade are located at In one plane, it is ensured that camera more can intactly collect described first image corresponding to first operating body With the first operating body shade corresponding to second image.

For example, as shown in Figure 2 B, for a kind of possible embodiment of the present invention.In fig. 2b, first operating body is The hand of user.Described image collecting unit is positioned at the certain angle of the described first operation body side surface, and so, described image is adopted Collection unit can collect institute corresponding to described first image corresponding to first operating body and the first operating body shade State the second image.In fig. 2b, shadeless hand is first operating body, and hypographous hand is that first operating body is cloudy Shadow.In fig. 2b, the first position can be determined according to first operating body, and can be cloudy according to first operating body Shadow determines the second place, and in fig. 2b as can be seen that the first position and the second place overlap, it is seen then that First operating body described in Fig. 2 B has touched the surface in the projection operation face.Then if first operating body is grasped Make, the electronic equipment can respond to the operation.And can be seen that camera in fig. 2b and be located at side, so, From the perspective of camera, first operating body and the first operating body shade are in a plane, it is ensured that Camera more can intactly collect described first image corresponding to first operating body and first operating body is cloudy Second image corresponding to shadow.

In the embodiment of the present invention, the electronic equipment first operating body can be carried out in real time or timing monitors.Example Such as, the electronic equipment can be monitored by described image collecting unit to first operating body.

According to the first position and the second place, it is the contact projection operation to determine first operating body The surface in face, or not in contact with the surface in the projection operation face after, the electronic equipment can continue to described first grasp It is monitored as body, determines when first operating body leaves the projection operation face.When the electronic equipment monitors institute State the first operating body and have left the projection operation face, you can determine that first operating body carries out first end of operation, It can determine which kind of operation first operation is specially in succession, so as to the response according to corresponding to the described first operation determination Mode.

For example, the electronic equipment, which monitors first operating body, have left the projection operation at the first moment Face, then the electronic equipment can determine first end of operation that first operating body is carried out, the electronic equipment can Judge that first operation has with the time of contact according to first operating body and the projection operation face and/or contact trace Which kind of operation body is, be may thereby determine that and the described first corresponding response mode of operation.

If for example, the electronic equipment monitors at the second moment determines first operating body and the projection operation Face is in contact, and first moment monitoring after second moment determines that first operating body have left the projection Operating surface, then the electronic equipment can determine the time difference between second moment and first moment.It is if described Time difference is not more than preset duration threshold value, then what the electronic equipment can determine that first operating body carried out is to click behaviour Make.If the time difference is more than the preset duration threshold value, the electronic equipment can determine the first operating body institute What is carried out is that long-press operates, i.e., the operation pinned for a long time.

If for example, the electronic equipment monitors at the second moment determines first operating body and the projection operation Face is in contact, and first moment monitoring after second moment determines that first operating body have left the projection Operating surface, the 3rd moment monitoring after first moment determine that first operating body connects with the projection operation face To touch, the 4th moment after the 3rd moment monitors again determines that first operating body have left the projection operation face, Then the electronic equipment can determine that the very first time between second moment and first moment is poor, first moment With the second time difference between the 3rd moment, and can determine between the 3rd moment and the 4th moment the 3rd Time difference.If these three time differences, no more than the preset duration threshold value, the electronic equipment can determine described What one operating body was carried out is once-through operation, such as the operation can be double click operation.If there is one in three time differences More than the preset duration threshold value, then what the electronic equipment can determine that first operating body carried out is to operate twice, The electronic equipment can according to the very first time, poor and described second time difference determines why this operates difference twice respectively Kind operation.

Preferably, the electronic equipment except the time of contact according to first operating body and the projection operation face come It is specially which kind of operation is outer to judge first operation, can also connecing by first operating body and the projection operation face Rail-engaging mark or the simultaneously contact trace and the time of contact judge which kind of operation first operation is specially.

If for example, the electronic equipment monitors at the second moment determines first operating body and the projection operation Face is in contact, and first moment monitoring after second moment determines that first operating body have left the projection Operating surface, then the electronic equipment can determine that first operating body exists between second moment and first moment The trace information streaked on the projection operation face.For example, the electronic equipment can determine first operating body in institute Threeth positional information of second moment corresponding on the projection operation face is stated, and first operating body can be determined in institute Fourth positional information of first moment corresponding on the projection operation face is stated, then, if the 3rd positional information institute is right The 3rd position answered is same position with the 4th position corresponding to the 4th positional information, or the 3rd position with it is described The distance between 4th position is not more than the second pre-determined distance, then the electronic equipment can determine first operating body in institute State and do not moved on projection operation face, then what first operating body was carried out is likely to single-click operation, or long-press operation etc., And if the 3rd position and the 4th position are not same position, or between the 3rd position and the 4th position Distance be more than second pre-determined distance, then what first operating body was carried out is likely to slide.
