The blood pressure information includes mean arterial pressure values. When the skin of a user is touched by a touch body, namely when the arm of the user is pressed, pressure is generated on the blood vessel of the user, so that the arterial pressure value of the user in a short time is changed. Based on the above, whether the skin of the projection display interface is touched by the touch body can be determined according to the artery pressure value. The following describes a process of determining whether the skin of the projection display interface is touched by a touch object by using a specific example.
The processor determines whether the skin of the projection display interface is touched by the touch object according to the blood pressure information acquired by the first sensor, and the method specifically includes:

And in the case that the difference value is larger than a preset threshold value, the processor determines that the skin of the projection display interface is touched by the touch body.
And under the condition that the difference value is smaller than or equal to the preset threshold value, the processor determines that the skin of the projection display interface is not touched by the touch body.
In this example, the initial mean arterial pressure value is an arterial pressure value at which the arm of the user is not subjected to external pressure, and the initial mean arterial pressure value may be determined from the historical blood pressure information acquired by the first sensor. The mean arterial pressure value is the mean arterial pressure value acquired by the first sensor at the current moment.
During the use of the wearable device by the user, the first sensor may monitor the mean arterial pressure value of the user at the current moment in real time and compare the mean arterial pressure value at the current moment with a preset initial mean arterial pressure value. When the difference between the average arterial pressure value at the current moment and the initial average arterial pressure value is greater than the predetermined threshold, that is, when the abrupt change of the average arterial pressure value at the current moment is greater than the predetermined threshold, it is determined that the arm of the user is subjected to the external pressure, that is, the skin of the projection display interface is touched by the touch object. Under the condition that the difference value between the average arterial pressure value at the current moment and the initial average arterial pressure value is smaller than or equal to the preset threshold value, namely under the condition that the mutation quantity of the average arterial pressure value at the current moment is smaller than or equal to the preset threshold value, the arm of the user is considered not to be subjected to external pressure, namely the skin of the projection display interface is not touched by the touch body.
In the embodiment of the application, before the projection assembly is controlled to work according to the position information of the touch object acquired by the second sensor, whether the skin of the projection display interface is touched by the touch object is determined according to the blood pressure information acquired by the first sensor, so that the error identification rate of the wearable device can be reduced.
Taking the second sensor 40 including the first distance sensor 41 and the second distance sensor 42 as an example, a process of determining a touch position where the touch object touches the projection display interface will be described.
In this example, the determining, by the processor, the touch position of the touch projection display interface by the touch object according to the position information of the touch object acquired by the second sensor specifically includes:
the processor determines the position information of the touch body according to first distance information acquired by the first distance sensor and second distance information acquired by the second distance sensor.
And the processor determines the touch position of the touch projection display interface of the touch body according to the position information of the touch body.
For example, fig. 3 shows a schematic diagram of a user touching a projection display interface, as shown in fig. 3, 301 is the projection display interface, and point C is the position of the finger of the user. Fig. 4 shows a schematic diagram of a process for determining position information of a touch object, as shown in fig. 4, first distance information (x) is a distance from a first distance sensor 41 (point a) to a user finger (point C), second distance information (y) is a distance from a second distance sensor 42 (point B) to the user finger (point C), and a position of the user finger (point C), that is, position information of the touch object, can be determined according to an intersection of the first distance information (x) and the second distance information (y).

For example, during the use of the wearable device by the user, the first sensor may monitor the mean arterial pressure value of the user at the current time in real time and compare the mean arterial pressure value at the current time with a preset initial mean arterial pressure value. Under the condition that the difference value between the average arterial pressure value at the current moment and the initial average arterial pressure value is larger than a preset threshold value, namely under the condition that the mutation amount of the average arterial pressure value at the current moment is larger than the preset threshold value, the arm of the user is considered to be subjected to external pressure, namely the skin of the projection display interface is touched by a touch body, and at the moment, the blood pressure information is determined to meet the preset condition. Under the condition that the difference value between the average arterial pressure value at the current moment and the initial average arterial pressure value is smaller than or equal to a preset threshold value, namely under the condition that the mutation quantity of the average arterial pressure value at the current moment is smaller than or equal to the preset threshold value, the arm of the user is considered not to be subjected to external pressure, namely the skin of the projection display interface is not touched by a touch body, and at the moment, the blood pressure information is determined not to meet the preset condition.
In the embodiment of the application, the blood pressure information acquired by the first sensor is acquired, and the projection assembly is further controlled to work according to the position information of the touch body acquired by the second sensor under the condition that the blood pressure information meets the preset condition, so that the false recognition rate of the wearable device can be reduced.

Step S5311, determining position information of the touch object according to the first distance information and the second distance information.
Step S5312, determining a touch position of the touch object on the touch projection display interface according to the position information of the touch object.
For example, fig. 3 shows a schematic diagram of a user touching a projection display interface, as shown in fig. 3, 301 is the projection display interface, and point C is the position of the finger of the user. Fig. 4 shows a schematic diagram of a process for determining position information of a touch object, as shown in fig. 4, first distance information (x) is a distance from a first distance sensor 41 (point a) to a user finger (point C), second distance information (y) is a distance from a second distance sensor 42 (point B) to the user finger (point C), and a position of the user finger (point C), that is, position information of the touch object, can be determined according to an intersection of the first distance information (x) and the second distance information (y).

The touch position of the projection display interface may be, for example, position information of an interaction control in the projection display interface. In specific implementation, the target action corresponding to the touch position may be determined according to a pre-stored mapping relationship between the target action and the touch position of the projection display interface and the touch position at which the touch body touches the projection display interface, and the projection component is controlled to execute the target action.
