detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

Figure 1 shows a first embodiment of the invention.

Fig. 1 is a schematic flowchart of a smart watch-based method for prompting overeating according to the first embodiment of the present invention. The method of this embodiment can be executed by a smart watch-based method device for prompting overeating, the device can be implemented by means of hardware and/or software, and can generally be integrated into a smart watch.

The method for prompting overeating based on the smart watch includes:

Step S101 , when an overeating event is triggered, acquire the current physiological parameter value of the user.

The user can make the smart watch implement the function of prompting overeating through the preset buttons or switches in the smart watch, or execute the function of prompting overeating by running corresponding software. When the smart watch receives an event triggered by the user to prompt an overeating event, it acquires the user's current physiological parameter values through various devices configured on the smart watch. For example, use a thermometer configured on a smart watch to measure the user's current body temperature.

Step S102, estimating the user's diet value according to the current physiological parameter value.

The user's diet can be estimated from the user's physiological parameter values. For example, the user's diet is estimated based on the user's eating time. Since the user's eating speed basically does not change greatly, the user's diet is simply estimated according to the user's eating time. In addition, since some physiological parameters, such as heart rate, etc. will also change when the user is eating, the amount of the user's diet can be comprehensively estimated according to the physiological parameter values obtained in step S101.

Step S103, prompting the user to overeat when the estimated food intake value is greater than the preset food intake threshold.

The value of the food intake estimated in step S102 is compared with a preset food intake threshold, which can be input or confirmed by the user in advance according to his own situation or expectation. If the estimated food intake value is greater than the preset food intake threshold, the smart watch will prompt the user to inform the user that the current diet is excessive, so that the user can stop eating according to the reminder to protect their health.

As an optional mode provided by the embodiment of the present invention, the smart watch can prompt the user to overeat by vibrating, making a sound, or turning on the screen. Since the smart watch is worn on the user's wrist, when the smart watch vibrates, makes a sound or lights up the screen, it can attract the user's attention and play a role in reminding the user of overeating.

The embodiment of the present invention comprehensively estimates the user's diet by using the smart watch to obtain the physiological parameter values of the user's diet, and compares the estimated diet with the preset diet threshold, and when the estimated diet value is greater than the preset When the food intake threshold is set, the user is prompted to overeat. It can effectively prevent users from overeating and protect their health.

Figure 2 shows a second embodiment of the invention.

Fig. 2 is a schematic flowchart of the method for prompting overeating based on smart watches provided by the second embodiment of the present invention. The embodiment of the present invention is based on the method for prompting overeating based on smart watches provided in the first embodiment of the present invention . Further, the acquisition of the current physiological parameter value of the user is specifically optimized as follows: acquisition of the data of height, weight and gender input by the user; acquisition of the user's heart rate data measured by the heart rate sensor in the smart watch; The accelerometer, gyroscope and timer obtain the user's eating time length; and calculate the calorie consumption of the user in the eating process according to the heart rate data, eating time length and the data of the height, weight and gender.

Referring to Fig. 2, the method for prompting overeating based on the smart watch includes:

Step S201 , when the event of overeating is triggered, acquire the data of height, weight and gender input by the user.

Users will also lose a certain amount of calories during the eating process, and different users consume different calories and calorie consumption during the eating process. For example, there is a large difference in calorie consumption between adult men and children during the eating process, and the calculated calorie consumption needs to be adjusted according to different physical characteristics of users. The user is required to provide the corresponding height, weight and gender data of the current user, and the smart watch receives the data input by the user and uses it as the basic data for calculating the calorie consumption of the user during eating.

Step S202, acquiring the user's heart rate data measured by the heart rate sensor in the smart watch.

The smartwatch is equipped with a heart rate sensor that can determine instant blood flow by detecting how much red blood absorbs green light. When the heart contracts, the blood flow is large, so the green light absorption is also large; on the contrary, when the heart diastole, the blood flow is small, and the green light absorption is also relatively small, the heart rate sensor can pass through hundreds of times per second. The user's heart rate can be obtained by light irradiation and monitoring of regular changes in green light absorption.

In step S203, the user's eating time is acquired through the accelerometer, gyroscope and timer in the smart watch.

The smart watch is worn by the user. The accelerometer and gyroscope in the smart watch can obtain the smart watch, that is, the user's current exercise state. If the user is in a state of motion, the accelerometer and gyroscope in the smart watch will measure the change of the corresponding value; if the accelerometer and gyroscope do not measure data, it can be considered that the current user is in a static state. Generally, when the user eats, the body will not have strenuous activities. The timer starts timing when the accelerometer and gyroscope do not measure data, and the user's eating time can be obtained.

Step S204, calculating the calorie consumption of the user during the eating process according to the heart rate data, the eating time length and the data of the height, weight and gender.

The calorie consumption of the user during the eating process is comprehensively calculated through the heart rate data acquired in steps S201, S202, and S203, the eating time length, and the data of the height, weight, and gender.

Step S205, estimating the user's diet value according to the current physiological parameter value.

Step S206, prompting the user to overeat when the estimated food intake value is greater than the preset food intake threshold.

In the embodiment of the present invention, the acquisition of the user's current physiological parameter value is specifically optimized as follows: acquisition of the data of height, weight and gender input by the user; acquisition of the user's heart rate data measured by the heart rate sensor in the smart watch; The accelerometer, gyroscope and timer in the watch acquire the user's eating time length; and calculate the calorie consumption of the user during the eating process according to the heart rate data, the eating time length and the data of the height, weight and gender. When estimating the user's diet value, the user's calorie consumption during eating is fully considered, and accurate user physiological parameters are obtained through the smart watch, making the estimated diet value more accurate.

Figure 3 shows a third embodiment of the invention.

Fig. 3 is a schematic flowchart of the method for prompting overeating based on a smart watch provided by the third embodiment of the present invention. The embodiment of the present invention is based on the method for prompting overeating based on a smart watch provided in the second embodiment of the present invention . Further, the optimization of estimating the user's eating amount based on the current physiological parameter value is: estimating the user's eating amount according to the heart rate data, the eating time length, and the user's calorie consumption during the eating process.

Referring to Fig. 3, the method for prompting overeating based on the smart watch includes:

Step S301, when the event of overeating is triggered, acquire the data of height, weight and gender input by the user.

Step S302, acquiring the user's heart rate data measured by the heart rate sensor in the smart watch.

In step S303, the user's eating time is acquired through the accelerometer, gyroscope and timer in the smart watch.

Step S304, calculating the calorie consumption of the user during the eating process according to the heart rate data, the eating time length and the data of the height, weight and gender.

Step S305, estimating the amount of the user's diet according to the heart rate data, the duration of the diet and the calorie consumption of the user during the diet.

The user's eating volume is closely related to the eating time, the longer the eating time, the greater the eating volume. At the same time, because the stomach needs a lot of exercise and blood to transport nutrients and oxygen during the process of digesting food, the heart will beat faster and the heart rate will increase. The amount the user eats is linearly related to the heart rate data, the calorie consumption during the eating process, and the length of eating time. Its specific calculation method is as follows:

d=k1*a+k2*b+k3*c, where, d is the estimated amount of the user’s diet, a is the heart rate data; b is the calorie consumption of the user during the eating process; c is the length of eating time; k1, k2 and k3 are preset coefficients, which can be selected according to experience.

Step S306, when the estimated food intake value is greater than the preset food intake threshold, prompting the user to overeat.

In the embodiment of the present invention, the estimation of the user's diet according to the current physiological parameter value is optimized as: estimating the user's diet according to the heart rate data, the length of the eating time and the user's calorie consumption during the eating process, It can make the estimated diet value more accurate, effectively prevent the user from overeating, and protect the user's health.

Further, before prompting that an overeating event is triggered, the following steps are added: acquire the user's physiological parameters during normal eating determined by the user, determine the user's normal eating amount value according to the user's physiological parameters during normal eating, and convert the The normal food intake value is used as the food intake threshold.

Referring to Fig. 4, the method for prompting overeating based on the smart watch includes:

Step S401, acquiring the user's physiological parameters during normal eating determined by the user, determining the user's normal eating volume value according to the user's physiological parameters during normal eating, and using the normal eating volume value as the eating volume threshold.

Before the user triggers the event that prompts the user to overeat, the normal amount of the user's diet needs to be obtained. The user's normal diet can be taken as the normal diet by obtaining the value manually input by the user in advance, but the normal diet obtained in this way is often based on the user's own wishes and cannot actually reflect the user's actual normal diet. In the embodiment of the present invention, the smart watch acquires the physiological parameters of the user when eating normally through the user eating normally. Determine the user's normal eating volume value according to the user's physiological parameters during normal eating, and display the determined user's normal eating volume value to the user. After the user confirms, the determined normal food intake value can be used as the food intake threshold value.

In another implementation of the embodiment of the present invention, it is also possible to obtain the user's physiological parameters during normal eating for many times, and determine the user's normal eating volume value according to the user's physiological parameters, calculate the average value of the normal eating volume, and use the The mean value was used as the food intake threshold.
