Wherein, the intelligent wearable device can be any feasible device, such as an intelligent bracelet, an intelligent collar and the like. In addition, the physiological characteristic signals collected by the intelligent wearable device are used as the basis for adjusting the navigation page, the natural attributes of the person are utilized, namely the behavior trend of the person is inertial and is influenced by the external environment, when the person is in a oppressive environment and a happy environment, the mood and the behavior of the person are different, and if the person intends to visit the website at the moment, the target website is also related to the website. Therefore, the method and the device realize dynamic and accurate navigation page display.
As described in the step S1, a display instruction of a navigation page is received, where multiple websites are integrated on the navigation page. The plurality of web sites integrated on the navigation page may be any feasible web site, for example, an entertainment-related web site, such as a video web site, a novel web site, or the like, or a learning-related web site, for example, a training web site, or a work-related web site.
As described in step S2, the physiological characteristic signal of the current cycle sent by the smart wearable device is obtained, and a first curve of the physiological characteristic signal of the current cycle changing with time is drawn. It should be emphasized that the navigation page of the present application does not show a static fixed website, and the displayed website is related to the physiological characteristic signal of the user, so that the physiological characteristic signal of the current period sent by the smart wearable device needs to be acquired.

The standard physiological characteristic signal is used for comparing with the physiological characteristic signal of the current period. The standard physiological characteristic signal can be obtained in advance in any feasible manner, for example, by collecting physiological characteristic signals of a plurality of cycles of a user of the intelligent wearable device and then selecting the physiological characteristic signal of a specified cycle from the physiological characteristic signals (the selection method can adopt any feasible method, for example, the number of extreme points of the physiological characteristic signals is calculated firstly, and then the physiological characteristic signal of the cycle corresponding to the minimum number of the extreme points is used as the physiological characteristic signal of the specified cycle, wherein the extreme points refer to the numerical values of the points which are greater than the numerical values of two points directly connected with the extreme points); and then acquiring a navigation page displayed on a screen of the page display terminal in the specified period, and taking the navigation page at the moment as the navigation page of the specified period, namely the standard navigation page corresponding to the standard physiological characteristic signal.

As described in step S8, the web address integrated on the standard navigation page is modified according to the at least one environmental image, so as to obtain an improved navigation page.

Specifically, the page display terminal receives a display instruction of the navigation page, so that the improved navigation page is directly displayed on the screen, and a user can go to a target website through the improved navigation page at the fastest speed. Further, the improved navigation page further comprises a website address manually added by the user in advance, for example, the website address is added through the preference and the use habit of the user, and the website address is arranged in any mode of characters or pictures. Furthermore, labels and brief introduction are attached to the website address, so that the user can conveniently perform screening and quick search in multiple dimensions. Furthermore, the improved navigation page also comprises recommended websites according to the use habits and the use frequency of the user, so that the website content is enriched, and the speed of the user directly going to the target website is improved.
In one embodiment, the step S4 of calculating the difference degree value between the first curve and the second curve according to a preset curve difference value calculation method includes:
s401, generating a first time sequence function P (t) corresponding to the first curve, and generating a second time sequence function L (t) corresponding to the second curve;
s402, according to a formula:
r (t) MIN (j (t), V), wherein
Obtaining a function R (t), wherein P (t) is the first timing function, L (t) is the second timing function, t is time, MIN is a minimum function, V is a preset parameter, and V is greater than 0;

The above formula not only considers the numerical value difference between the curves, but also considers the variation trend difference between the curves along with the time, so that the difference degree value is more accurate, and the final determination of the environment image is ensured.
In one embodiment, the step S5 of extracting at least one difference region from the first curve according to a preset difference region extraction method includes:
s501, judging whether the first time length of the function R (t) is a continuous time length or not;
s502, if the first time length of the function R (t) is not continuous time length, dividing the first time length of the function R (t) into a plurality of continuous sections, wherein the two different sections are not continuous;
s503, judging whether the lengths of the continuous sections are all larger than a preset time length threshold value;
and S504, if the length unevenness of the plurality of continuous sections is larger than a preset time length threshold, recording the sections with the lengths larger than the preset time length threshold as designated sections, and taking the designated sections as difference areas to perform extraction processing.
