DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The embodiments of the present invention will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are merely used to explain the present invention, rather than being understood as limitations to the present invention. On the contrary, the embodiments of the present invention include all the changes, modifications and equivalents falling into the scope of the spirit and principles of the appended claims.

[0020] FIG. 1 is a schematic flowchart of a method for prompting based on smart glasses proposed by one embodiment of the present invention, the method comprising:

[0021] S11: the smart glasses acquire current scenario information.

[0022] The smart glasses are an emerging smart device wearable on the head. The smart glasses, like a smart phone, have an independent operating system, may be installed with programs like software and games by a user, be operated and controlled to implement functions such as agenda addition, map navigation, friend interaction, photo capturing and video capturing, video chatting with friends, etc., and may implement wireless network access via a mobile communication network.

[0023] The current scenario information may be acquired by way of images or by way of device interconnection.

[0024] By way of images means to capture the current scenario to acquire an image of the current scenario, while by way of device interconnection means that a device on which the current scenario is located sends the current scenario information to the smart glasses.

[0025] Furthermore, capturing the current scenario may be continuous capturing, or capturing after receiving an event trigger instruction. For example, continuous capturing is started when PPT is enabled or a movie starts to play, so as to acquire an image of the current scenario. Alternatively, when the current scenario is to be captured, an event trigger instruction such as a touch instruction or a voice control instruction is used to start capturing the current scenario. The trigger instruction or voice control instruction may be sent by a user; in addition, the user may also send a trigger instruction to the smart glasses by means of another device, so as to start capturing the current scenario.

[0026] By way of device interconnection, for example, the page number of the PPT that is currently played by a computer and the like may be sent to a smart device.

[0027] S12: the smart glasses determine prompt information corresponding to the current scenario information according to a preconfigured information base, the information base storing at least one kind of scenario information and prompt information corresponding to each kind of scenario information; [0028] wherein the information base records an association relationship between the scenario information and the prompt information, through which the prompt information corresponding to the current scenario information can be found.

[0029] The current scenario information is, for example, an image of the PPT page currently played, and the information base saves the image of the PPT page and the corresponding prompt information which indicates, for example, the content that needs to be extended in the current PPT page. Alternatively, the current scenario information is a video frame currently played, the video frame comprising a face or faces of a certain celebrity or some celebrities, and the information base saves the face of a celebrity and information related to that celebrity, for example, a correlation between information such as the name, and experience, in which facial recognition technology may be used to acquire a face from the current video frame.

[0030] S13: the smart glasses display the prompt information by means of the smart glasses.

[0031] For example, when explaining a PPT, the content that needs to be extended and is not displayed on the projector may be displayed, or when a celebrity is seen, data related to that celebrity may be displayed.

[0032] This embodiment can facilitate a user in seeing prompt information corresponding to the current scenario and improve user experience by means of acquiring the prompt information corresponding to the current scenario information and displaying same by means of the smart glasses.

[0033] FIG. 2 is a schematic flowchart of a method for prompting based on smart glasses proposed by another embodiment of the present invention, the method comprising:

[0034] S21: an information base is established.

[0035] The information base saves at least one kind of scenario information and prompt information corresponding to each kind of scenario information. By means of establishing an information base, scenario information and prompt information may be associated.

[0036] The scenario information and the corresponding prompt information may be information set by a user himself, or information acquired from public resources.

[0037] For example, when explaining a PPT, the user may, in advance, input in the information base each page of PPT picture and corresponding prompt information set by himself, or set the page number of the PPT and the corresponding prompt information; or [0038] the user may input in the information base the scenario information and the corresponding prompt information acquired from public resources. For example, as to celebrities, the faces of these celebrities and the corresponding celebrity information may be acquired from public resources.

[0039] S22: current scenario information is acquired.

[0040] The current scenario information may be acquired by way of images or by way of device interconnection.

[0041] By way of images means to capture the current scenario to acquire an image of the current scenario, while by way of device interconnection means that a device on which the current scenario is located sends the current scenario information to the smart glasses.

[0042] Furthermore, capturing the current scenario may be continuous capturing, or capturing after receiving an event trigger instruction. For example, continuous capturing is started when PPT is enabled or a movie starts to play, so as to acquire an image of the current scenario. Alternatively, when the current scenario is to be captured, an event trigger instruction such as a touch instruction or a voice control instruction is used to start capturing the current scenario. The trigger instruction or voice control instruction may be sent by a user; in addition, the user may also send a trigger instruction to the smart glasses by means of another device, so as to start capturing the current scenario.

[0043] By way of device interconnection, for example, the page number of the PPT that is currently played by a computer and the like may be sent to a smart device.

[0044] S23: prompt information corresponding to the current scenario information is determined in the information base.

[0045] For example, the current scenario information is, an image of the PPT page currently played, and the information base saves the image of the PPT page and the corresponding prompt information which indicates, for example, the content that needs to be extended in the current PPT page. Alternatively, the current scenario information is a video frame currently played, the video frame comprising a face or faces of a certain celebrity or some celebrities, and the information base saves the face of a celebrity and information related to that celebrity, for example, a correlation between information such as the name, and experience, in which facial recognition technology may be used to acquire a face from the current video frame.

[0046] S24: the prompt information is displayed by means of the smart glasses in real time.

[0047] For example, when explaining a PPT, the content that needs to be extended and is not displayed on the projector may be displayed, or when a celebrity is seen, data related to that celebrity may be displayed.

[0048] The above-mentioned prompt information may be displayed at a location above the right eye of the smart glasses.

[0049] Furthermore, before the display of the prompt information, whether the prompt information needs to be displayed may be judged, so as to display same only when needed. A button may be set in advance, the button being used for enabling or disabling all the prompt information, and when the button is enabled, the current scenario information and the corresponding prompt information are displayed after being acquired. Alternatively, a part of the prompt information may also be enabled or disabled, for example, displaying the corresponding prompt information when the current scenario meets a set condition, otherwise not displaying same. The set condition may be the time when the user stares at a scenario, and the corresponding prompt information is displayed only when the time exceeds a set threshold. For example, the location where the user's eyeball stares is captured by means of an arranged sensor, and when the time of staring exceeds a set threshold, the corresponding prompt information, such as the face of a certain celebrity, is displayed at the location.

[0050] Furthermore, real-time display of prompt information is taken as an example above, and non-real-time display may also be performed.

[0051] This embodiment, by means of establishing an information base, may find prompt information corresponding to current scenario information in the information base, and by means of showing the prompt information on smart glasses, may enable a user to see the prompt information directly without acquiring same from another device, which facilitates the acquisition of the prompt information by the user, and by means of displaying the prompt information in real time, may enable the user to acquire the corresponding prompt information in real time according to the current scenario and may improve user experience. Displaying on the smart glasses may enrich device functions.

[0052] FIG. 3 is a structural schematic diagram of an apparatus for prompting based on smart glasses proposed by another embodiment of the present invention. The apparatus 30 comprises an acquisition module 31, a determination module 32 and a display module 33.

[0053] The acquisition module 31 is used for acquiring current scenario information; [0054] the current scenario information may be acquired by way of images or by way of device interconnection.

[0055] By way of images means to capture the current scenario to acquire an image of the current scenario, while by way of device interconnection means that a device on which the current scenario is located sends the current scenario information to the smart glasses.

[0056] Furthermore, capturing the current scenario may be continuous capturing, or capturing performed after receiving an event trigger instruction. For example, continuous capturing is started when PPT is enabled or a movie starts to play, so as to acquire an image of the current scenario. Alternatively, the current scenario is to be captured, an event trigger instruction such as a touch instruction or a voice control instruction is used to start capturing the current scenario. The trigger instruction or voice control instruction may be sent by a user; in addition, the user may also send a trigger instruction to the smart glasses by means of another device, so as to start capturing the current scenario.

[0057] By way of device interconnection, for example, the page number of the PPT that is currently played by a computer and the like may be sent to a smart device.

[0060] The current scenario information is, for example, an image of the PPT page currently played, and the information base saves the image of the PPT page and the corresponding prompt information which indicates, for example, the content that needs to be extended in the current PPT page. Alternatively, the current scenario information is a video frame currently played, the video frame comprising a face or faces of a certain celebrity or some celebrities, and the information base saves the face of a celebrity and information related to that celebrity, for example, a correlation between information such as the name, and experience, in which facial recognition technology may be used to acquire a face from the current video frame.

[0061] The display module 33 is used for displaying the prompt information by means of the smart glasses.

[0062] For example, when explaining a PPT, the content that needs to be extended and is not displayed on the projector may be displayed, or when a celebrity is seen, data related to that celebrity may be displayed.

[0063] This embodiment can facilitate a user in seeing prompt information corresponding to the current scenario and improve user experience by means of acquiring the prompt information corresponding to the current scenario information and displaying same by means of the smart glasses.

[0064] FIG. 4 is a structural schematic diagram of an apparatus for prompting based on smart glasses proposed by another embodiment of the present invention. The apparatus 30 further comprises an establishment module 34 used for establishing the information base.

[0065] The establishment module 34 is specifically used for: saving scenario information set by a user and prompt information corresponding to the scenario information in the information base; or saving scenario information acquired by the user from public resources and prompt information corresponding to the scenario information in the information base.

[0066] The information base saves at least one kind of scenario information and prompt information corresponding to each kind of scenario information. By means of establishing an information base, scenario information and prompt information may be associated.

[0067] The scenario information and the corresponding prompt information may be information set by a user himself, or information acquired from public resources.

[0068] For example, when explaining a PPT, the user may, in advance, input in the information base each page of PPT picture and corresponding prompt information set by himself, or set the page number of the PPT and the corresponding prompt information; or [0069] the user may input in the information base the scenario information and the corresponding prompt information acquired from public resources. For example, as to celebrities, the faces of these celebrities and the corresponding celebrity information may be acquired from public resources.

[0070] In another embodiment, the acquisition module 31 is specifically used for: capturing a current scenario to acquire an image of the current scenario.

[0071] In another embodiment, the acquisition module is further specifically used for: capturing the scenario continuously to acquire an image of the current scenario; or capturing the current scenario according to an event trigger instruction.

[0072] In another embodiment, the event trigger instruction used by the acquisition module comprises: a touch instruction or a voice control instruction given by the user; or a trigger instruction sent by the user via another device.

[0107] By way of device interconnection, for example, the page number of the PPT that is currently played by a computer and the like may be sent to a smart device.

[0108] S23': prompt information corresponding to the current scenario information is determined in the information base.

[0109] For example, the current scenario information is, an image of the PPT page currently played, and the information base saves the image of the PPT page and the corresponding prompt information which indicates, for example, the content that needs to be extended in the current PPT page. Alternatively, the current scenario information is a video frame currently played, the video frame comprising a face or faces of a certain celebrity or some celebrities, and the information base saves the face of a celebrity and information related to that celebrity, for example, a correlation between information such as the name, and experience, in which facial recognition technology may be used to acquire a face from the current video frame.

[0110] S24': the prompt information is displayed by means of the smart glasses in real time.

[0111] For example, when explaining a PPT, the content that needs to be extended and is not displayed on the projector may be displayed, or when a celebrity is seen, data related to that celebrity may be displayed.

[0112] The above-mentioned prompt information may be displayed at a location above the right eye of the smart glasses.

[0113] Furthermore, before the display of the prompt information, whether the prompt information needs to be displayed may be judged, so as to display same only when needed. A button may be set in advance, the button being used for enabling or disabling all the prompt information, and when the button is enabled, the current scenario information and the corresponding prompt information are displayed after being acquired. Alternatively, a part of the prompt information may also be enabled or disabled, for example, displaying the corresponding prompt information when the current scenario meets a set condition, otherwise not displaying same. The set condition may be the time when the user stares at a scenario, and the corresponding prompt information is displayed only when the time exceeds a set threshold. For example, the location where the user's eyeball stares is captured by means of an arranged sensor, and when the time of staring exceeds a set threshold, the corresponding prompt information, such as the face of a certain celebrity, is displayed at the location.

[0114] Furthermore, real-time display of prompt information is taken as an example above, and non-real-time display may also be performed.

[0115] This embodiment, by means of establishing an information base, may find prompt information corresponding to current scenario information in the information base, and by means of showing the prompt information on smart glasses, may enable a user to see the prompt information directly without acquiring same from another device, which facilitates the acquisition of the prompt information by the user, and by means of displaying the prompt information in real time, may enable the user to acquire the corresponding prompt information in real time according to the current scenario and may improve user experience. Displaying on the smart glasses may enrich device functions.
