Foldable electronic device including magnetic sensor and method for preventing open/closed recognition malfunction thereof

A method performed by an electronic device for preventing opening/closing recognition erroneous operations of the electronic device, the electronic device including a first housing, a second housing foldably coupled to the first housing, a first magnetic body disposed in the first housing, a second magnetic body disposed in the second housing, a first sensor configured to detect a change in magnetic force according to a distance between the first magnetic body and the second magnetic body, at least one second sensor configured to detect a folding angle between the first housing and the second housing, a first processor connected to the first sensor through a first data line and an interrupt line, the first data line being configured to transfer first sensor data and the interrupt line being configured to transfer an interrupt signal in case that a magnetic force condition is satisfied based on the change in magnetic force, a second processor connected to the at least one second sensor through a second data line configured to transfer data from the at least one second sensor, the second data line branching off from a node of the interrupt line so as to be connected to the first sensor, and memory, comprising one or more storage media, storing instructions, the method comprising:

• outputting, by the first sensor, a first interrupt signal indicating a second state to the first processor and the second processor through the interrupt line in case that, while the electronic device is recognized as being in a first state, a first recognition condition which causes a change from the first state to the second state is satisfied by a change in magnetic field measured by the first sensor;
• activating, by the second processor, the at least one second sensor and angle calculation processing circuitry in response to receiving the first interrupt signal, thereby calculating the folding angle between the first housing and the second housing;
• maintaining, by the first processor or the second processor, recognition of the first state in case that the folding angle is included in a first state condition;
• and
• recognizing that the electronic device has changed from the first state to the second state in case that the folding angle is outside the first state condition.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, in which the electronic device includes a first housing, a second housing foldably coupled to the first housing, a first magnetic body disposed in the first housing, a second magnetic body disposed in the second housing, a first sensor configured to detect a change in magnetic force according to a distance between the first magnetic body and the second magnetic body, at least one second sensor configured to detect a folding angle between the first housing and the second housing, a first processor connected to the first sensor through a first data line and an interrupt line, the first data line being configured to transfer first sensor data and the interrupt line being configured to transfer an interrupt signal in case that a magnetic force condition is satisfied based on the change in magnetic force, a second processor connected to the at least one second sensor through a second data line configured to transfer data from the at least one second sensor, the second data line branching off from a node of the interrupt line so as to be connected to the first sensor, and memory, comprising one or more storage media, storing instructions, cause the electronic device to perform operations, the operations comprising:

• outputting, by the first sensor, a first interrupt signal indicating a second state to the first processor and the second processor through the interrupt line in case that, while the electronic device is recognized as being in a first state, a first recognition condition which causes a change from the first state to the second state is satisfied by a change in magnetic field measured by the first sensor;
• activating, by the second processor, the at least one second sensor and angle calculation processing circuitry in response to receiving the first interrupt signal, thereby calculating the folding angle between the first housing and the second housing;
• maintaining, by the first processor or the second processor, recognition of the first state in case that the folding angle is included in a first state condition;
• and
• recognizing that the electronic device has changed from the first state to the second state in case that the folding angle is outside the first state condition.
