The terminal device is generally provided with a plurality of physical keys, and a user clicks the keys to perform functions such as volume control, power on/off or photographing. On some terminal devices, a plurality of keys are arranged side by side in a straight line, and the interval between two adjacent keys is small. If the user performs blind operation on a plurality of keys, the user cannot see the positions of the correctly estimated keys, which is easy to cause false triggering of the keys.
Referring to fig. 1, a schematic flow chart of a key-based instruction triggering method is provided in an embodiment of the present application. The present embodiment is exemplified by applying a processing method of instruction triggering to a terminal device, where the instruction triggering method based on a key may include the following steps:
s101, detecting the state of each key in the N keys when the N keys are pressed simultaneously.
The terminal equipment is provided with N entity keys, the types of the keys can be touch keys or mechanical keys, when a user presses the keys, a pressing event can occur on the keys firstly, and then a lifting event occurs on the keys after a certain time. The terminal device may measure the magnitude of the level on the key to detect a press event or a lift event occurring on the key. In an initial state, N keys arranged on the terminal equipment are all in an un-pressed state, and when the terminal equipment detects that pressing events simultaneously occur on the N keys, the state of each key in the N keys is detected. It should be noted that, in this embodiment, it is not necessarily required that the N keys are pressed at the same time point, a certain time error may be allowed, and as long as an error between the time points of the N key press events is smaller than the duration threshold, it is considered that the N keys are pressed by the user at the same time, that is, the terminal detects that the N keys are pressed at the same time, and the specific duration threshold may be determined according to actual requirements, which is not limited in this embodiment.
When the N keys are pressed simultaneously, the terminal detects the states of the keys in the N keys, mainly detects which key in the N keys is switched from the pressed state to the lifted state, and the detection mode can be realized by detecting the level.
In one or more embodiments, the method further comprises:
when the N keys are all in a lifted state, generating a second instruction when detecting that a second pressing operation occurs on any one key in the N keys; and executing the function indicated by the second instruction.
And the second pressing operation consists of a pressing event and a lifting event, N keys arranged on the terminal are all in a lifting state under the condition that the user does not perform any key operation on the terminal equipment, at the moment, the terminal equipment detects that the pressing event occurs on any key in the N keys, then determines a corresponding function according to the ID of the key when the lifting event occurs on the key, and then executes the function.
S102, detecting the state of the target key when the lifting event occurs on the target key.
When the target key is lifted, namely a user releases the pressing of the target key, the target key is switched from a pressed state to a lifted state, and in the process of switching the pressed state of the target key to the lifted state, other keys except the target key in the N keys are still kept in the pressed state. The terminal detects the state of the target key, mainly detects whether the target key is switched from the lifting state to the pressing state again.
In one or more embodiments, the detecting the state of the target key includes:
when the fact that the level of the target key is switched from a first level to a second level is detected, determining that a pressing event occurs on the target key;
and when the fact that the level of the target key is switched from the second level to the first level is detected, determining that a lifting event occurs on the target key.
The first level and the second level may be determined according to actual requirements, the first level may be greater than the second level or smaller than the second level, and a difference between the first level and the second level should be large, so that sufficient discrimination is ensured.
S103, generating a first instruction when a first pressing operation occurs on the target key.
The first pressing operation consists of two processes of a pressing event and a lifting event, and under the condition that other keys except for the target key in the N keys are still in a pressed state, if the first pressing operation occurs on the target key, a first instruction is generated, and the function of the first instruction can be determined according to actual requirements, for example: the first command has the functions of volume control, photographing, video recording or power on and off. In addition, the time interval between the pressing event and the lifting event in the first pressing operation is smaller than a first preset time, and the first pressing operation is a short pressing operation, the size of the first preset time may be determined according to an actual requirement, which is not limited in this embodiment.
In one or more embodiments, further comprising:
and before the first pressing operation is finished, stopping detecting the states of the N keys if the other keys except the target key in the N keys are lifted.
The first pressing operation is composed of a pressing event and a lifting event, namely, if other keys except the target key in the N keys are switched from a pressing state to a lifting state before the lifting event is completed, the terminal equipment does not generate and execute the first instruction, and the terminal equipment stops detecting the states of the N keys.
In one or more embodiments, when the keys other than the target key of the N keys are pressed, a time interval between the lift event occurring on the target key and the first pressing operation should be less than a second duration threshold, and the size of the second duration threshold may be determined according to actual requirements.
And S104, executing the function indicated by the first instruction.
And the terminal equipment determines the ID of the target key and the function corresponding to the pressing mode according to the preset mapping relation and executes the function.
The following describes, by way of example, the key-based instruction triggering method according to the present application with reference to fig. 2, where the terminal device in fig. 2 is an AR glasses, the AR glasses are provided with 3 physical keys, that is, a key 1, a key 2, and a key 3 from left to right, and a forefinger in fig. 2 corresponds to the key 1, a middle finger corresponds to the key 2, and a ring finger corresponds to the key 3. Optionally, 3 buttons on the AR glasses are arranged in a straight line, and the AR glasses are further provided with a blind guiding column, so that a user can conveniently position the buttons during blind operation, and the blind guiding column can be arranged in front of or behind the 3 buttons. When a user does not perform any key operation on the AR glasses, keys 1 to 3 on the AR glasses are all in a lifted state, when the index finger, the middle finger and the ring finger of the user simultaneously press the 3 keys, when the AR glasses detect that the keys 1 to 3 simultaneously press down events, the AR glasses detect the states of the keys 1 to 3, and when the AR glasses detect that one key in the keys 1 to 3 is lifted up and other cases are still in a pressed state, the state of the key is detected; assuming that the target key is the key 2, when the key 1 and the case 3 are in a pressed state and the lift event occurs on the key 2, the AR glasses detect the states of the keys 1 to 3 to be continuously detected, when the first pressing operation occurs on the key 2, a first instruction is generated according to the ID of the key 2, the AR glasses execute the function indicated by the first instruction, and the key 1 and the key 3 are always in a pressed state before the first pressing operation is completed. If at least one key in the keys 1 and 3 is lifted before the first pressing operation is finished, a first instruction is not generated, and the states of the keys are continuously detected.
As can be seen from the above, when a simultaneous pressing event of multiple keys is detected, the states of the multiple keys are detected, and if a lifting event occurs to a target key of the multiple keys but other keys are still in a pressed state, an instruction is generated according to the pressing operation occurring on the target key, and a function instructed by the instruction is executed. Therefore, the user can accurately determine the target key to be clicked by pressing the key through a plurality of fingers to realize the accurate positioning of the key, and then execute the corresponding function on the pressing of one key in the keys, so that the possibility of carrying out false triggering on the key in full operation is reduced.

In this embodiment, it is not necessarily required that the N keys are pressed at the same time point, a certain time error may be allowed, and as long as an error between the time points of the N key press events is smaller than the duration threshold, it is considered that the N keys are pressed by the user at the same time, that is, the terminal detects that the N keys are pressed at the same time, and the specific duration threshold may be determined according to actual requirements, which is not limited in this embodiment.
For example: the time of the pressing event on the key 1 is t1, the time of the pressing event on the key 2 is t2, the time of the pressing event on the key 3 is t3, and the time threshold value is 0.1ms, and the simultaneous pressing events on the key 1, the key 2 and the key 3 are determined as long as the time interval between any two times of t1, t2 and t3 is less than 0.1ms of the time threshold value.
And S303, detecting the state of the target key when the lifting event occurs on the target key.
When the target key is lifted, namely a user releases the pressing of the target key, the target key is switched from a pressed state to a lifted state, and in the process of switching the pressed state of the target key to the lifted state, other keys except the target key in the N keys are still kept in the pressed state. The terminal detects the state of the target key, mainly detects whether the target key is switched from the lifting state to the pressing state again.
S304, generating a first instruction when the first pressing operation is generated on the target key.
The first pressing operation consists of two processes of a pressing event and a lifting event, and under the condition that other keys except for the target key in the N keys are still in a pressed state, if the first pressing operation occurs on the target key, a first instruction is generated, and the function of the first instruction can be determined according to actual requirements, for example: the first command has the functions of volume control, photographing, video recording or power on and off. In addition, the time interval between the pressing event and the lifting event in the first pressing operation is smaller than a first preset time, and the first pressing operation is a short pressing operation, the size of the first preset time may be determined according to an actual requirement, which is not limited in this embodiment.
