Electronic device and method with function of preventing key-press from false action

Abstract

The invention discloses an electronic device with the function of preventing the misoperation of a key and a method thereof. The electronic device comprises a touch type key and a processing unit. The touch type key comprises a main touch inductive zone and an auxiliary ouch inductive zone. The auxiliary ouch inductive zone is arranged around the main touch inductive zone. When an object is in contact with the touch type key, the main touch inductive zone can generate a main touch inductive signal; and the auxiliary ouch inductive zone can generate an auxiliary ouch inductive signal. The processing unit can receive the main touch inductive signal and the auxiliary ouch inductive signal. The touch type key can induce the main touch inductive signal and the auxiliary ouch inductive signal through the processing unit, so as to determine whether the touch type key can act or not. Therefore, the complicated actions of locking and unlocking a press-key lock can be avoided when the electronic device in use every time. When being applied in determination/dialing-out keys or rejection/hanging-up keys and other touch type keys, the method for preventing the misoperation of the key can effectively avoid the situation of dialing outwards or hanging-up in a non-early warning manner caused by cheek misoperation during the conversation.

Description

technical field [0001] The present invention relates to an electronic device with a touch key, and in particular to an electronic device with a touch key for preventing malfunction of the key. Background technique [0002] With the advancement of technology, mobile devices (handheld devices) have become commonly used auxiliary tools in daily life. For example, common mobile devices include personal digital assistants (personal digital assistants; PDAs), mobile phones (mobile phones), smart phones (smart phones), etc. These mobile devices are light in size and easy to carry, so the more people use them More and more functions are required, and the application of products is more diverse. [0003] These mobile devices must accept the operator's instructions when performing functions, so the operation convenience of the input interface is very important. For example, the touch button is a very popular input interface at present, but due to the touch Control buttons may move o...

[0003] These mobile devices must accept the operator's instructions when performing functions, so the operation convenience of the input interface is very important. For example, the touch button is a very popular input interface at present, but due to the touch Control buttons may move once they are touched, sometimes causing unexpected actions

Take a mobile phone as an example. When answering a call, the user often puts the phone close to the face and talks, so that the dial button or the hang up button of the phone senses the action, and the call is dialed out or hung up without warning.
