     DETAILED DESCRIPTION 
     Example embodiments of the present application are further described below in detail with reference to the accompanying drawings (in which like elements are denoted by like reference numerals) and description. The following embodiments are used for describing the present application, but are not intended to limit the scope of the present application. 
     Those skilled in the art may understand that the terms such as “first” and “second” in the present application are used only to differentiate different steps, devices, modules, or the like, and neither represent any specific technical meaning, nor indicate any necessary logical relationship between the terms. 
     In a process that a user is in a moving state or on an object (e.g., a vehicle) in a moving state, when the user reads display contents on a handheld or wearable user equipment, or uses a user equipment with a self-snapshot function such as a mobile phone and a smart watch for self-snapshotting, the user equipment may often move relative to the head of the user due to bumping movement, thus disturbing the reading, the self-snapshotting and other events, for example, the user&#39;s eyes get tired easily, the shooting effect is poor and the like. 
     As shown in  FIG. 1 , one example embodiment of the present application provides an information processing method, comprising: 
     S 110 : acquiring eye movement information related to that at least one eye of a user gazes the user equipment; and 
     S 120 : determining relative movement information of the user equipment relative to the head of the user at least according to a non-saccade eye movement part in the eye movement information. 
     For example, the information processing apparatus according to the present application is used as an execution body of this embodiment, to perform S 110 -S 120 . Specifically, the information processing apparatus may be disposed in a user equipment through software, hardware or a combination of software and hardware, or the information processing apparatus itself is the user equipment; the user equipment comprises, but is not limited to, a smartphone, a tablet computer, a smart watch, smart frame glasses, a smart helmet and the like. 
     According to the example embodiment of the present application, relative movement between a user equipment and the head of a user is determined according to a non-saccade eye movement part(s) of eye movement information related to the user gazes the user equipment, especially suitable for determining relative movement between the user and the user equipment in a scenario where the user and the user equipment move at the same time, providing a basis for making compensation corresponding to the relative movement more accurately. 
     The steps of the embodiment of the present application are further described through the following example embodiment: 
     S 110 : Acquire eye movement information related to that at least one eye of a user gazes the user equipment. 
     Herein, the at least one eye may be one eye of the user; or may also be two eyes of the user. 
     In one example embodiment, the gazing the user equipment, for example, may be: gazing contents displayed by a display module on the user equipment, for example, reading displayed texts and images; watching displayed video and the like. 
     In example embodiment, the gazing the user equipment, for example, may be: gazing physical components on the user equipment, for example, gazing a lens of a self-snapshot camera on the user equipment. 
     In one example embodiment, when the user performs an action such as reading, in addition to shaking caused by the above bumping, the head has no other active actions (e.g., rotate), at this point, the eye movement information comprises first movement information related to movement of the at least one eye in a corresponding eye socket. 
     In another example embodiment, the head of the user may also actively perform other actions, at this point, in addition to the first movement information, the eye movement information may further comprise second movement information related to movement of the head of the user. 
     In one example embodiment, optionally, S 110  may comprise: capture the eye movement information through an eye movement information capturing module. 
     In one example embodiment, the eye movement information capturing module, for example, may be an image capturing module towards the user&#39;s eyes, configured to capture an image of the at least one eye of the user, and obtain the eye movement information through image analysis (e.g., the position of the pupil in the eye socket). 
     In another example embodiment, the eye movement information capturing module, for example, may comprise an Electro-Oculogram (EOG) signal capturing module disposed on the at least one eye of the user. At this point, the eye movement information, for example, may be EOG information; or may be movement information of the at least one eye obtained according to the EOG information. 
     In one example embodiment, optionally, it is possible to capture the eye movement information at the side of the user equipment. For example, it is possible to capture an image of the at least one eye through an eye-facing camera on the user equipment. 
     In another example embodiment, optionally, it is feasible to capture the eye movement information at the side of the eye of the user. For example, it is feasible to capture the eye movement information through an eye-facing camera or an EOG detection module on a headset device of the user. 
     In one example embodiment, optionally, S 110  may further comprise: acquiring the eye movement information from at least one external device through a communication module. For example, the eye movement information is acquired from the user equipment or the headset device described above. 
     S 120 : Determine relative movement information of the user equipment relative to the head of the user at least according to a non-saccade eye movement part in the eye movement information. 
     In a process that the user observes an object daily, eye movement usually comprises three types: 
     saccade eye movement, eye movement in a process that the user&#39;s eye changes from one observed object to another observed object, characterized by great angular velocity and angular acceleration and visual processing suspension in the process; 
     fixation eye movement, an action of the corresponding eye when the user&#39;s eye observes an object stationary relative to the user (in the process, the user&#39;s eye is not moving, and in the example embodiment, the non-movement serves as a special example of movement); and 
     smooth pursuit eye movement, movement of the eye in the process that the user&#39;s eye tracks and observes an objective moving relative to the user; compared with the saccade eye movement, the eye movement corresponding to the smooth pursuit eye movement is gentler. 
     Wherein, the fixation eye movement and the smooth pursuit eye movement are eye movement corresponding to that the user intentionally gazes an object. 
     When a user gazes a user equipment, if his/her eye movement information comprises the fixation eye movement and/or the smooth pursuit eye movement described above, it indicates that the user is intentionally gazing an object on the user equipment. In the process, if the user equipment makes relative movement relative to the head of the user, this may be embodied in the user&#39;s eye movement information. Therefore, in the embodiment of the present application, the relative movement is determined by using the non-saccade eye movement part in the eye movement information. 
     In one example embodiment, optionally, the non-saccade eye movement part comprises: a smooth pursuit eye movement part corresponding to the smooth pursuit eye movement in the eye movement information. 
     For example, in one possible application scenario, a user reads static display contents such as texts and images displayed on a display module of a user equipment, when the user is static relative to the user equipment, the user&#39;s eye movement information should only comprise a fixation eye movement part and a saccade eye movement part. Once the head of the user moves relative to the user equipment, the static display contents move relative to the head of the user, the original fixation eye movement part becomes a smooth pursuit eye movement part. Therefore, in one example embodiment, S 120  can obtain relative movement information of the head of the user relative to the user equipment only according to the smooth pursuit eye movement part. 
     In another example embodiment, optionally, the non-saccade eye movement part comprises: a smooth pursuit eye movement part corresponding to the smooth pursuit eye movement in the eye movement information, and a fixation eye movement part corresponding to the fixation eye movement in the eye movement information. 
     For example, in one possible application scenario, the display module of the user equipment may display dynamic display contents such as video. Therefore, in a situation where the head of the user is static relative to the user equipment, the user&#39;s eye movement information may also comprise a smooth pursuit eye movement part, at this point, the relative movement information cannot be determined merely relying on the smooth pursuit eye movement part, but the relative movement information needs to be determined by using the smooth pursuit eye movement part and the fixation eye movement part at the same time. 
     In one example embodiment, optionally, the method may further comprise: 
     processing the eye movement information to obtain the non-saccade eye movement part. 
     For example, in one example embodiment, the eye movement information comprises eye rotation angular velocity information, and/or rotation amplitude information and the like; if the eye movement information is processed according to movement features corresponding to the eye movements described above, parts in the eye movement information which correspond to the eye movements can be determined. 
     In other example embodiments, for example, when the eye movement information comprises EOG information, it is also feasible to obtain EOG feature information corresponding to the eye movements according to pre-learning, and then after the EOG information is obtained, the non-saccade eye movement part in the eye movement information can be obtained by processing the EOG information according to the EOG feature information. 
     In one example embodiment, optionally, S 120  may comprise: 
     determining the relative movement information at least according to the non-saccade eye movement part and at least one reference non-saccade eye movement information. 
     The at least one reference non-saccade eye movement information, for example, may be: a non-saccade eye movement part in the eye movement information acquired by the user through a current gaze action in a condition of being static relative to the user equipment. For example, the user is reading texts displayed on the user equipment currently, for example, the user is reading a visual novel; the reference non-saccade eye movement information may be a non-saccade eye movement part in the eye movement information corresponding to the texts displayed on the user equipment read by the user in the static condition. 
     In one example embodiment, the determining the relative movement information at least according to the non-saccade eye movement part and at least one reference non-saccade eye movement information, for example, may comprise: 
     comparing the non-saccade eye movement part with reference non-saccade eye movement information in the at least one reference non-saccade eye movement information which corresponds to the eye movement information, to determine the relative movement information according to their difference. 
     In one possible scenario, for example, the user equipment is displaying a dynamic image currently, for example, the user equipment is playing a video, at this point, the user may gaze a moving object in the video. Therefore, in one example embodiment, optionally, S 120  may further comprise: 
     determining the relative movement information at least according to the non-saccade eye movement part and content display information of the user equipment. 
     Herein, the content display information, for example, may be movement information of each object in the dynamic image. In one example embodiment, for example, it is possible to determine an object watched by the user according to the eye movement information, and then determine eye movement information (having smooth pursuit eye movement corresponding to tracking the object) that the user should correspond to in a condition that the head of the user is static relative to the user equipment, and then obtain the relative movement information according to the difference between the non-saccade eye movement part and the eye movement information the user should correspond to. 
     Definitely, in one example embodiment, while the user watches a moving object, the object itself may also correspond to non-saccade reference eye movement information, and S 120  may further comprise: 
     determining the relative movement information according to the non-saccade eye movement part, the content display information and the at least one reference non-saccade eye movement information. 
     For example, when the user reads text contents in a floating window on a webpage displayed by the user equipment, it is feasible to, after it is determined that the user is reading contents in the floating window, obtain the relative movement information according to the non-saccade eye movement part in the eye movement information, movement information of the floating window, and reference non-saccade eye movement information of the displayed texts read by the user. 
     In one example embodiment, optionally, S 120  may further comprise: 
     determining the relative movement information at least according to the non-saccade eye movement part and movement information of the user equipment corresponding to the period corresponding to the non-saccade eye movement part. 
     In the example embodiment, before S 120 , the method may further comprise: acquiring the movement information. 
     Herein, the movement information, for example, may be at least one inertial sensing information of the user equipment, and it is feasible to acquire the information through at least one inertial sensor of the user equipment. The at least one inertial sensor, for example, may comprise at least one of the following: 
     at least one acceleration sensor, at least one gyroscope, at least one magnetic sensor, at least one gravity sensor and the like. 
     The movement information, for example, may comprise the at least one inertial sensing information captured by the at least one inertial sensor. 
     In one example embodiment, when the execution body of the information processing method is located at the side of the user equipment, the acquiring the movement information, for example, may comprise: 
     acquiring the movement information through the at least one inertial sensor of the user equipment. 
     In another example embodiment, for example, when the execution body is not located at the side of the user equipment, the acquiring the movement information may further comprise: 
     acquiring the movement information from at least one external device through communication. 
     The at least one external device, for example, may comprise the user equipment. 
     In one example embodiment, optionally, the determining the relative movement information at least according to the non-saccade eye movement part and movement information may comprise: 
     determining eye movement components of the non-saccade eye movement part corresponding to at least one movement feature of the movement information; and 
     determining the relative movement information at least according to the eye movement components. 
     In one example embodiment, the at least one movement feature may comprise at least one of the following: 
     movement change frequency feature, movement change amplitude feature and movement change phase feature. 
     For example, in one example embodiment, optionally, S 120  may comprise: 
     determining a part where eye movement information change frequencies in the non-saccade eye movement part match movement change frequency feature of the movement information; the difference between this part of the non-saccade eye movement part and eye movement information that the movement information should corresponding to is the corresponding part of the relative movement information. 
     Similarly, in one possible scenario, the user may also watch dynamic images displayed on the user equipment, at this point, it is also possible to combine the content display information to determine the relative movement information more accurately; therefore, in one example embodiment, S 120  may further comprise: 
     determining the relative movement information at least according to the non-saccade eye movement part, the content display information and movement information of the user equipment corresponding to the period corresponding to the non-saccade eye movement part. 
     According to the embodiment of the present application, through the implementations described above, it is feasible to determine relative movement information between the user and the user equipment more accurately, and the relative movement information can be applied to multiple aspects, bringing about better user experience to the user. For example, it is feasible to predict a relative movement rule between the user and the user equipment in a future period of time according to current relative movement information between the user and the user equipment, thus performing a corresponding operation. 
     For example, in one example embodiment, after the relative movement information is determined, the method further comprises: 
     adjusting display of a display content of the user equipment according to the relative movement information. 
     In the example embodiment, by adjusting the content display of the user equipment, it is feasible to eliminate or reduce bad effects, for example, increase reading fatigue or the like, brought about to the user by relative movement between the user and the user equipment corresponding to the relative movement information. 
     For example, in one example embodiment, the adjusting display of a display content of the user equipment according to the relative movement information may comprise: 
     determining a display shifting parameter of the display content of the user equipment according to the relative movement information; and 
     displaying the display content according to the display shifting parameter; 
     wherein the display shifting parameter is configured to perform display stabilizing compensation on a relative movement corresponding to the relative movement information. 
     Herein, the display shifting parameter, for example, may comprise at least one of: compensation speed, compensation time, and shifting amplitude. 
     The example embodiment is further described through the following application scenario. 
     In one possible application scenario, a user uses a user equipment on a moving vehicle, wherein bumping movement x(t) of the vehicle is transferred to the user equipment and the head of the user respectively through different channels, causing their movements to be different, a movement rule of a display module of the user equipment is y D (t), and a movement rule of the head of the user is y H (t). 
     When static display contents such as texts and images of the display module of the user equipment are read, due to existence of relative movement between the display module and the head of the user, when the user reads the contents with the eye, their movement difference y D (t)−y H (t) has to be compensated by the eye, causing the original fixation eye movement for the texts in the display contents to become frequent smooth pursuit eye movement w(t) at certain amplitude, and such additional smooth pursuit movement increases the burden of the eye, causing discomfort such as fatigue and dizziness. 
     To reduce the user&#39;s discomfort in reading, it is necessary to eliminate or reduce the movement difference y D (t)−y H (t) through an image stabilizing technology, to eliminate or reduce the additional smooth pursuit eye movement, for example, to try to achieve an effect of w(t)=0. 
     In one example embodiment, the method of eliminating the movement difference y D (t)−y H (t) comprises: 
     adding compensation movement corresponding to the movement difference y D (t)−y H (t) to the display content displayed by the display module, to cause movement of the display content relative to the head of the user to be 0. 
     For example, generally, when a user reads a mobile phone, the eye is at a distance about 25 cm to 50 cm from the screen; the amplitude of relative shaking of the mobile phone at which uncomfortable reading is caused is generally within 0.2-3 cm. By taking the vertical direction of reading as example, as shown in  FIG. 2 , when bumping occurs during reading, if a gaze point moves a distance of Δy relative to a human eye, the view variation Δφ caused by the gaze point of human eye pursuit shake is:
 
Δφ=Δ y/D   (1)
 
     wherein D is a distance from the eye to the gaze point. 
     The distance D from the eye to the screen during reading is regarded as a constant, and by calculating a derivative of time for two sides of the formula (1), the following formula can be obtained:
 
ω= Dv   (2)
 
     wherein ω is angular velocity during smooth pursuit eye movement of an eyeball, and v is linear velocity of the gaze point corresponding to the eye; it is thus clear that, when the eyeball has angular velocity corresponding to the smooth pursuit eye movement in a certain direction, the compensation velocity V D  of the desired screen display content is:
 
 v   D   ≈ω/D   (3)
 
     For example, in one example embodiment, it is feasible to determine compensation for the display content at the time of k+1 through smooth pursuit eye movement information of the user acquired at the time of k: 
     1) in the beginning: compensation speeds in horizontal and vertical directions of the display content are both set as 0, that is,
 
 v   DH ( t| 0)=0 ; v   DV ( t| 0)=0
 
     2) if horizontal and vertical components of smooth pursuit detected at the time of k are respectively ω H (t|k), ω V (t|k); 
     the compensation speeds in horizontal and vertical directions at the time of k+1 are respectively updated as:
 
 v   DH ( t|k+ 1)= v   DH ( t|k )−ω H ( t|k )/ D;  
 
 v   DV ( t|k+ 1)= v   DV ( t|k )−ω V ( t|k )/ D;  
 
     3) if no smooth pursuit is detected at the time of k,
 
 v   DH ( t|k+ 1)= v   DH ( t|k );
 
 v   DV ( t|k+ 1)= v   DV ( t|k ).
 
     The above is merely one example embodiment of adjustment of the content display; those skilled in the art can know that the manner of adjusting other parameters of the content display to eliminate or reduce the bad effects can also be applied to the embodiment of the present application, for example, in one example embodiment, relative movement corresponding to the relative movement information comprises changes of a relative angle, for example, a relative elevation angle changes, and at this point, it is also feasible to adjust a display perspective parameter of the display content. 
     Those skilled in the art can see that, through the above adjustment, it is feasible to make the display content watched by the user rest or move less relative to the user when the head of the user makes relative movement relative to the user equipment, causing the user to feel more comfortable and tireless when watching the display content. 
     In one possible application scenario, a user uses a user equipment having a self-snapshot image capturing function for self-snapshotting, for example, when the user controls the user equipment for self-snapshotting through hands or a selfie stick or other tools, the user often needs to watch his/her own image displayed on the user equipment in advance and then takes a shot, in the process, if the user equipment moves relative to the head of the user, the image shot often has a poor effect. Therefore, in one example embodiment, in response to that the user equipment is in a self-snapshot image capturing state, the method further comprises: 
     adjusting a shooting parameter of the user equipment according to the relative movement information, to perform shooting shake compensation on a relative movement corresponding to the relative movement information. 
     It can be seen by those skilled in the art that, in the present application, when shooting shake compensation is performed on the relative movement to cause the user to move relative to the user equipment, it is also possible to obtain a better self-snapshotting image effect and improve user experience. 
     It should be understood by those skilled in the art that, in any one of the foregoing methods of the implementations of the present application, the value of the serial number of each step described above does not mean an execution sequence, and the execution sequence of each step should be determined according to the function and internal logic thereof, and should not be any limitation to the procedure of the implementations of the present application.

     a first determination sub-unit  3221 , configured to determine eye movement components of the non-saccade eye movement part corresponding to at least one movement feature of the movement information; and 
     a second determination sub-unit  3222 , configured to determine the relative movement information at least according to the eye movement components. 
     In one example embodiment, the at least one movement feature may comprise at least one of the following: 
     movement change frequency feature, movement change amplitude feature and movement change phase feature. 
     In one possible scenario, for example, the user equipment is displaying a dynamic image currently, for example, the user equipment is playing a video, at this point, the user may gaze a moving object in the video. Therefore, in one example embodiment, optionally, as shown in  FIG. 4 d   , the relative movement determination module  320  may comprise: 
     a third determination unit  323 , configured to determine the relative movement information at least according to the non-saccade eye movement part and content display information of the user equipment. 
     Herein, the content display information, for example, may be movement information of each object in the dynamic image. 
     Definitely, in one example embodiment, while the user watches a moving object, the object itself may also correspond to non-saccade reference eye movement information; at this point, the third determination unit  323  may further determine the relative movement information according to the non-saccade eye movement part, the content display information and the at least one reference non-saccade eye movement information. 
     In another example embodiment, optionally, the third determination unit  323  may further determine the relative movement information according to the non-saccade eye movement part, the content display information and movement information of the user equipment corresponding to the period corresponding to the non-saccade eye movement part. 
     According to the embodiment of the present application, through the above example embodiments, it is feasible to determine relative movement information between the user and the user equipment more accurately, and the relative movement information may be applied to multiple aspects, bringing about better user experience to the user. For example, it is feasible to predict a relative movement rule between the user and the user equipment in a future period of time according to current relative movement information between the user and the user equipment, thus making a corresponding operation. 
     For example, as shown in  FIG. 4 e   , in one example embodiment, the apparatus  300  further comprises: 
     a display adjustment module  350 , configured to adjust display of a display content of the user equipment according to the relative movement information. 
     In the example embodiment, by adjusting the content display of the user equipment, it is feasible to eliminate or reduce bad effects, for example, increase reading fatigue or the like, brought about to the user by relative movement between the user and the user equipment corresponding to the relative movement information. 
     In one example embodiment, optionally, the display adjustment module  350  comprises: 
     a display parameter determination unit  351 , configured to determine a display shifting parameter of the display content of the user equipment according to the relative movement information; and 
     a display unit  352 , configured to display the display content according to the display shifting parameter; 
     wherein the display shifting parameter is configured to perform display stabilizing compensation on a relative movement corresponding to the relative movement information. 
     In one possible application scenario, a user uses a user equipment having a self-snapshot image capturing function for self-snapshotting, for example, when the user controls the user equipment for self-snapshotting through hands or a selfie stick or other tools, the user often needs to watch his/her own image displayed on the user equipment in advance and then takes a shot, in the process, if the user equipment moves relative to the head of the user, the image shot often has a poor effect. Therefore, in one example embodiment, the apparatus  300  further comprises: 
     a self-snapshot module  360 , configured to capture a self-snapshot image of the user; and 
     a self-snapshot parameter adjustment module  370 , configured to adjust a shooting parameter of the self-snapshot module according to the relative movement information, to perform shooting shake compensation on a relative movement corresponding to the relative movement information. 
     It can be seen by those skilled in the art that, in the present application, when shooting shake compensation is performed on the relative movement to cause the user to move relative to the user equipment, it is also possible to obtain a better self-snapshotting image effect and improve user experience. 
     Reference can be made to the corresponding description in the embodiment shown in  FIG. 1  for further description about the functions of the modules and units in the embodiment of the present application.
