Abstract

The embodiment of the invention discloses a capacitive non-contact answering method, and belongs to the technical field of intelligent learning. The method comprises the following steps: detecting whether a finger exists in a detection plane which is above an answering screen and has a fixed distance with the answering screen or not; when it is detected that the finger is placed in the detection plane, collecting the current value of a preset RC series circuit in the answer screen under the detected finger; calculating an equivalent capacitance value of the capacitive sensor according to the currently collected current value of the RC series circuit; calculating the finger area sensed by the capacitive sensor according to the equivalent capacitance value of the capacitive sensor; judging whether the finger area sensed by the capacitance sensor meets a preset capacitance triggering requirement or not; and if the finger area sensed by the capacitive sensor meets a preset capacitance triggering requirement, triggering the capacitive sensor so as to perform answer input on the answer screen. According to the invention, the security of the electronic answering equipment can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent learning, in particular to a capacitive non-contact answering method. Background technique [0002] With the rapid development of computer technology, the online answering (non-paper answering) method has been applied, and it has been widely used because of its ease of use and low cost. At present, the electronic devices used for online answering are all contact-type, and there are mainly two specific methods: one is to answer questions through external input devices, such as keyboards, mice, etc.; the other is to input answers by touching the touch screen. Among them, the method of answering questions by touching the touch screen does not need an additional external input device, has the advantage of lightness, and has been liked by more people. [0003] However, no matter answering questions through an external input device or a touch screen, candidates’ fingers are required to touch the ex...
