FIG. 3 is a schematic flow chart of a method for processing information according to an embodiment of the disclosure. The method is also applied to the electronic device shown in FIG. 2. The method may include the following step S301-S305.
In the step S301, triggering information is acquired through the second sensor among the M sensors.
Implementations for the electronic device to acquire the triggering information through the second sensor may be referred to the foregoing embodiment, which is not repeated herein.
In the step S302, a graphical interaction interface is projected, in response to the triggering information, onto a first portion of a first operation body through the projection lens. The first portion of the first operation body is located on a same side as the second surface.
The graphical interaction interface displayed on the first operation body, i.e., on the arm of the user may be a small interface, a part of the interface, or an interface displaying prompting information.
In the step S303, a sliding operation performed on the graphical interaction interface by a second operation body is acquired through the first sensor.
The sliding operation performed on the graphical interaction interface by the second operation body may be a sliding operation away from the second surface.
In the step S304, a sliding distance of the sliding operation is determined.
The M sensors may include a third sensor, which is for detecting the sliding distance of the sliding operation. The third sensor may be exposed from the second surface of the frame structure. The third sensor may be, but not limited to a distance sensor. The distance sensor may detect the sliding distance of the sliding operation away from the second surface performed by the second operation body.
In the step S305, a size of the graphical interaction interface is changed based on the sliding distance of the sliding operation.
The electronic device may change the size of the graphical interaction interface based on the sliding distance detected by the third sensor. For example, the longer the sliding distance is, the larger the graphical interaction interface displayed on the first operation body is.
An example of changing the size of the graphical interaction interface is as shown in FIG. 4. A touch unit is provided at a side of the display of the electronic device. The touch unit is for detecting a touch operation performed by a finger of the user. The electronic device acquires the triggering information in the case that the user clicks the touch unit with his finger (as shown in FIG. 4a). The graphical interaction interface is projected onto the arm of user through the projection lens, and the graphical interaction interface projected onto the arm of the user is a small interface (as shown in FIG. 4b). The electronic device enlarges the small interface based on the sliding distance in the case that the finger of the user performs, on the small interface. the sliding operation away from the second surface (as shown in FIG. 4c).
In the method for processing information provided in the disclosure, the graphical interaction interface is projected onto the arm of the user, and the user may change the size of the graphical interaction interface projected onto the arm of the user with the sliding operation performed on the graphical interaction interface. The size of the graphical interaction interface is not limited by sizes of the electronic device and the display, thereby leading to a good user experience.
FIG. 5 is a schematic flow chart of a method for processing information according to an embodiment of the disclosure. The method is also applied to the electronic device shown in FIG. 2. The method may include the following steps S501-S505.
In the step S501, triggering information is acquired through the second sensor among the M sensors.
In the step S502, a graphical interaction interface is projected, in response to the triggering information, onto a first portion of a first operation body through the projection lens. The first portion of the first operation body is located on a same side as the second surface.
For example, the second sensor is a touch unit. The second sensor is arranged on the display exposed on the first surface of the frame structure. Prompting information is displayed on the display exposed on the first surface of the frame structure in the case that the electronic device receives information such as a short message. The electronic device acquires the triggering information in the case that a user clicks the touch unit to perform an operation on the prompting information displayed on the display. Then an interface displaying the prompting information is projected, in response to the triggering information, onto the first operation body.
In the step S503, a sliding operation performed by a second operation body on the interface displaying the prompting information is acquired through the first sensor.
The second operation body may be a hand of the user. For example, the first operation body is the left arm of the user, and the second operation body is right hand of the user. The electronic device projects the graphical interaction interface onto the left arm of the user through the projection lens, and the user performs, through the right hand of the user, an interaction operation on the graphical interaction interface displayed on the left arm of the user.
In the step S504, a sliding distance of the sliding operation is determined.
In the step S505, a size of the interface displaying the prompting information is changed based on the sliding distance of the sliding operation, and contents of the prompting information are displayed on a size-changed interface.
An example of changing the size of the interface displaying the prompting information may be referred to FIG. 4. A touch unit is provided at a side of the display of the electronic device. The touch unit is for detecting a touch operation performed by a finger of the user. The electronic device acquires the triggering information in the case that the user clicks on the touch unit with his finger (as shown in FIG. 4a). The graphical interaction interface is projected onto the arm of user through the projection lens, and the graphical interaction interface projected onto the arm of the user is a small interface (as shown in FIG. 4b). The electronic device enlarges the small interface based on the sliding distance in the case that the finger of the user performs, on the small interface, a sliding operation away from the second surface, and the contents of the prompting information are displayed on the enlarged interface (as shown in FIG. 4c). Assuming that the prompting information prompts that a short message is received, in the case that the electronic device obtains the sliding operation performed on the interface of the prompting information, the electronic device enlarges, based on the sliding distance of the sliding operation, the interface displaying the prompting information, and contents displayed in the enlarged interface are switched from the prompting information into contents of the short message.
With the method for processing information provided in the disclosure, the graphical interaction interface is projected onto the arm of the user, the user may change the size of the graphical interaction interface projected onto the arm of the user through the sliding operation performed on the graphical interaction interface, and the contents displayed in the graphical interaction interface may be changed. The size of the graphical interaction interface is not limited by sizes of the electronic device and the display, thereby leading to a good user experience.

In the step S602, an interface displaying application icons is projected, in response to the triggering information, onto a first portion of a first operation body. The first portion of the first operation body is located at a same side as the second surface.
According to the embodiment, the electronic device has a standard mode and a smart mode.
In the standard mode, the electronic device may only display information such as time on the display exposed on the first surface of the frame structure. It may be understood that the power is saved since the electronic device in the standard mode is only for displaying the information such as the time.
The electronic device switches from the standard mode to the smart mode in case of acquiring the triggering information. In the smart mode, the electronic device projects the interface displaying the application icons onto the first portion of the first operation body, and the electronic device may respond to an operation performed by a user on an application icon displayed in the interface displaying the application icons.
It should be noted that, in the smart mode, the display exposed on the first surface of the frame structure may display information or may not display information.
In the step S603, a touch operation performed by a second operation body on a first application icon among the application icons displayed in the interface is acquired through the first sensor.
In the step S604, a first application corresponding to the first application icon is started, and the interface displaying the application icons is switched into an interface of the first application program.
For example, as shown in FIG. 7, the electronic device under the standard mode switches from the standard mode to the smart mode in case of obtaining the triggering information. The interface displaying the application icons is projected onto an arm of the user through the projection lens. The user may perform an operation on an application icon among the application icons displayed in the interface. The user may click with his finger on an application icon among the application icons displayed in the interface to start the first application corresponding to the clicked application icon, and the electronic device switches from a current interface into an interface of the first application. For example, in the case that the user clicks on an icon of playing music, the electronic device starts a music playing application to play a song, and switches from the interface displaying the application icons into an interface of the music playing application.
With the method for processing information provided in the disclosure, the interface displaying the application icons may be projected onto an arm of the user. The user starts the first application through the touch operation performed on the first application icon among the application icons displayed in the interface, and the electronic device switches from the interface displaying the application icons into the interface of the first application. A size of a graphical interaction interface projected onto the arm of the user is not limited by sizes of the electronic device and the display, thereby leading to a good user experience.
FIG. 8 is a schematic flow chart of a method for processing information according to an embodiment of the disclosure. The method is also applied to the electronic device shown in FIG. 2. The method may include the following steps S601-S604.

The first sensor may be, but not limited to an image capture device such as a camera.
In the step S804, a sliding distance of the sliding operation is determined.
In the step S805, a size of a graphical interaction interface is changed based on the sliding distance of the sliding operation, and application icons including an application icon carrying the prompting information are displayed on the size-changed interface.
In the step S806, a touch operation performed by a second operation body on the application icon carrying the prompting information is acquired through the first sensor.
In the step S807, an interface displaying the application icons including the application icon carrying the prompting information is switched, in response to the touch operation, into an interface displaying contents of the prompting information.
For example, in the case that the electronic device receives three short messages, prompting information of “three short messages are received” is displayed on the display exposed on the first surface of the frame structure. Assuming that the second sensor is a touch unit arranged on the display, the electronic device acquires the triggering information in the case that the user clicks the displayed prompting information, and the interface displaying the prompting information is projected, in response to the triggering information, onto the first operation body. The interface displaying the prompting information may be a small interface displaying only the prompting information.
In the case that the sliding operation performed by a hand of the user on the interface displaying the prompting information is acquired through the first sensor, the electronic device enlarges, based on the sliding distance of the finger of the user, the interface displaying the prompting information. The contents displayed on the interface are changed. That is, the interface displaying the prompting information is switched into an enlarged interface displaying the application icons. A short message icon is displayed on the enlarged interface displaying the application icons. The short message icon may carry a sign “3” for prompting the user that three short messages are received.
In the case that a touch operation performed by the finger of the user on the short message icon displayed in the interface displaying the application icons is acquired by the first sensor, i.e., in the case that the user clicks the short message icon with his finger, the electronic device switched from a current interface displaying the application icons into an interface displaying contents of the three short messages. That is, the electronic device displays the contents of the short messages on the arm of the user.
