For example, described electronic equipment monitors described the first operating body and when first moment, has left described projection operation face, described electronic equipment can be determined described the first end of operation that described the first operating body carries out, described electronic equipment can judge which kind of operation described the first operation is specially according to the duration of contact of described the first operating body and described projection operation face and/or contact trace, thereby can determine the response mode with described the first operational correspondence.

For example, if described electronic equipment determines that in the second monitoring constantly time described the first operating body contacts with described projection operation face, the described first monitoring constantly after described second moment determines that described the first operating body has left described projection operation face, and described electronic equipment can determine described second constantly and the mistiming between described first moment.If the described mistiming is not more than default duration threshold value, what described electronic equipment can determine that described the first operating body carries out is single-click operation.If the described mistiming is greater than described default duration threshold value, what described electronic equipment can determine that described the first operating body carries out is long by operation, the operation of pinning for a long time.
